Export RIS Citation Information. TY - Tech Report AU - Dwyer, Carmine E. A2 - Applied Research Associates, Inc. A3 - Vermont Agency of Transportation A3 - United States. Department of Transportation. Federal Highway Administration AB - Pavement markings provide continuous safety information to roadway users related to the roadway alignment, vehicle positioning, and other important driving-related tasks. During nighttime hours on many roadways, pavement markings are the only roadway asset to guide and regulate traffic. Therefore, it is important that pavement markings are performing well, are both durable and retroreflective. However, there are many factors that can affect pavement marking performance, such as the environment, traffic, and winter maintenance practices. The Vermont Agency of Transportation (VTrans) experiences significant challenges with all these factors. Additionally, besides the potential safety risks to roadway travelers, there are financial costs to VTrans for frequently replacing markings. However, a relatively new pavement marking material, a polymer modified cement-based pavement marking, has the potential for being more durable than other marking materials. With a longer service life, it also has the potential for having a competitive annualized cost. In Spring 2025 VTrans awarded a research study to Applied Research Associates, Inc. (ARA) to conduct an evaluation of the cement-based marking. The objectives of the study were to perform a measured assessment of the marking's performance on VTrans roadways, determine an estimated service life, and from the service life calculate the material's annualized cost. However, the marking manufacturer, which had offered to install the test markings at no cost, did not follow through on that offer. Therefore, VTrans made the decision to cancel the study. This conduct of research report serves as a record of the work completed before the study's cancellation.

Department of Transportation. Federal Highway Administration AB - Over the past few years, considerable roadway damage has occurred in Vermont due to intense precipitation, leading to upslope landslides and debris flows (mixtures of boulders, trees and slurries) spilling onto roadways. Although landslide occurrence has a long history in the State, the debris flow phenomenon addressed in this work is relatively new to Vermont and needs further attention. The work is focused on non-channelized debris flows, that is, debris flows not specifically associated with gullies and channels developed through fluvial processes. Identifying areas susceptible to such debris flows and monitoring of these areas will facilitate asset management, improve roadway safety, potentially reduce the need for emergency road closures and help reduce long-term costs associated with repeated emergency responses. The susceptibility to debris flow is influenced by several factors such as slope angle, slope materials and rainfall intensity. The key outcome of this study was to create a map identifying high-hazard areas (susceptible to debris flow) for awareness, asset management and monitoring. We considered rainfall as the triggering factor to initiate debris flow and merged rainfall data with topographic and soil parameter data to produce a debris flow factor of safety map for a study area comprised of a 152 m (500 ft) buffer zone on either side of national and state routes. Three factor of safety groupings categorize the terrain in the buffer zone into stable, marginally unstable, and unstable, and thereby the debris flow potential in the design rainfall triggering scenario.

Export RIS Citation Information. TY - Tech Report AU - D'Angelo, Daniel AU - Hoyne, David A2 - Applied Research Associates A2 - Greenman-Pedersen Inc. A3 - Vermont Agency of Transportation A3 - United States. Department of Transportation. Federal Highway Administration AB - The Vermont Agency of Transportation (VTrans) is experiencing declining competition for bridge projects and rising construction costs. At the same time, demographic shifts are reducing workforce experience within both the Agency and the contracting community. Project plan content and quality processes have not evolved significantly since the Interstate era, despite major changes in construction materials, equipment, and technology. Currently, VTrans does not have a formal mechanism for obtaining feedback from the contracting community regarding project plans, risk allocation, and constructability. This research developed a framework to improve engagement with industry partners and enhance the quality and constructability of transportation projects. It is recommended that an oversight team be established to guide the implementation of the Framework. The Oversight Team would determine the implementation priority of each strategy (for example, addressing high risk themes first), identify the lead(s) of a Working Group for each strategy, identify the initial program areas to be involved, establish a schedule, provide guidance, and monitor progress. The research gained from this project will assist VTrans with improving efficiency and provide staff with tools to deliver better quality and more easily constructed projects expeditiously at lower costs and increased competition. The administration, construction and maintenance costs of projects will be reduced due to improved quality and constructability of project plans. The long-term benefit is a relationship that is built on trust, where all collaborators and partners are committed to advancing the state of practice, where voices are heard, challenges are overcome, and the process is respectful, transparent, and effective. Through this framework, the Agency, contractors, suppliers, and consultants will be more efficient because they have been engaged in a development process where the outcomes and results are well defined and understood.

Federal Highway Administration AB - This research investigated the use of recycled asphalt shingles (RAS) as a mechanical stabilizer in full depth reclamation (FDR)pavement rehabilitation. The study aimed to determine whether processed and minimally processed RAS could serve as sustainable alternatives to conventional stabilizers while diverting roofing waste from landfills. Laboratory testing was conducted on FDR materials from two reference projects (Marshfield-Danville and Cambridge-Johnson), blended with 5% and 10% RAS. Mechanical evaluations included indirect tensile strength, triaxial resilient modulus, and triaxial shear strength, while pavement performance was predicted using MnPAVE modeling. Results showed that the incorporation of 5% RAS, particularly minimally processed, maintained acceptable mechanical properties and service life, whereas higher contents reduced strength and stiffness. Processed RAS led to higher air voids, negatively affecting mixture performance, while minimally processed RAS improved cohesion and internal friction. Economic and environmental assessments, including life-cycle cost analysis (LCCA) and life-cycle assessment (LCA), indicated that 5% RAS is feasible when transport distances are similar to conventional aggregates and service life is not compromised. Field implementation and long-term monitoring are recommended to validate laboratory findings and optimize RAS use in practice.

This research builds upon previous research to develop improved low-cost robotic culvert inspection systems, i.e., the HIVE 2.0. The motivation is that culvert failures can be expensive and pose public safety hazards. Improved methods of assessing the condition of culverts facilitate the planning of maintenance and replacement projects. The policy of the Vermont Agency of Transportation (VTrans) is to inspect every culvert once every 5 years, resulting in about 9,600 culverts needing to be inspected annually. Culverts with small diameters, i.e. approximately 1-m (36-in) or less, preclude human inspection. The intended use of HIVEs is for small culvert inspections. This report describes the design, build and test of three HIVE variants: 1. HIVE 2.1 - A new and improved robot based on the Sherman tank platform of the HIVE 2.0; 2. HIVE 3.0 - A robot built on the same chassis as the HIVE 2.1, but with more sophisticated capabilities including teaming and increased autonomy; and 3.

Department of Transportation. Federal Highway Administration AB - Portland Cement Concrete (PCC) pavements still retain value after their useful design life. The most effective method to reuse PCC pavements is to recycle them as base/subbase layers. The Environmental Protection Agency's (EPA) Waste Reduction Model (WARM) estimates greenhouse gas (GHG) emissions savings of approximately 0.04 metric tons CO2e per short ton of PCC not landfilled. Recycling PCC in place can achieve GHG emissions savings of 0.01 metric tons of CO2e per short ton of aggregate replaced. PCC fracturing (FCP) methods generally include (1) rubblization (RCP) with steel to concrete bond ruptured,(2) crack-and-seat (C&S) for PCC without steel reinforcement, and (3) break-and-seat (B&S) for PCC with steel reinforcement. FCP structural coefficients, as shown below, are the recommended literature-reported values for the design of HMA overlays: RCP: 0.14 -0.30, C&S: 0.20 -0.35, B&S: 0.20 -0.35 The AASHTO AASHTOWare Pavement ME Design characterizes pavement materials hierarchically, commensurate with their importance, size, and cost to the project. MEPDG Manual of Practice recommended FCP modulus values are: RCP: 50 ksi to 150 ksi, C&S, B&S: 150 ksi to 1,000 ksi. The scheme used to estimate FCP layer coefficients is mathematically expressed as a FCP = 0.0045 ∛(EFCP). The estimated FCP layer coefficients for Pike, Tate, and Forrest/Jones counties are similar to those reported in the literature.

Department of Transportation AB - An up-to-date traffic sign inventory is essential for roadway safety, infrastructure maintenance, and support of intelligent road agents, yet traditional manual inspections are inefficient and labor-intensive. This research presents an automated system that leverages deep learning and computer vision to detect, classify, and generate a comprehensive traffic sign inventory from log videos and open street images. To enhance model performance, a new traffic sign dataset tailored to Washington state traffic scenarios was developed and used for training. Additionally, traffic sign condition assessment was explored using six retro-reflectivity-related features. The integrated system consists of four modules-detection, tracking, assessment, and inventory building-each designed to perform a specific function, with the final inventory visualized geospatially. For this system, sparse R-CNN was employed for detection and classification, while a DNN classifier was used for assessment. Experimental results demonstrated high detection accuracy (93.50 mAP@50) and reliable condition assessment (93.56 percent accuracy) while maintaining computational efficiency (25.4 FPS). A comparison with the Washington State Department of Transportation (WSDOT) inventory revealed key discrepancies. By automating traffic sign management, this system provides a scalable, cost-effective solution for transportation agencies to maintain accurate inventories, prioritize maintenance, and enhance roadway safety, thereby ensuring more reliable roadway and seamless mobility for all road users.

The technical framework consists of machine learning models for route- and event-level lane departure risk prediction leveraging different sources of emerging data. Field study is also conducted to assess lane marking conditions and how well lane detection function works using ADAS (Advanced Driver Assistance System) technology. Using the proposed framework and data from 2020 to 2022, we identify that driver age, driving speed, lighting condition, and surface condition are consistently the top factors contributing to lane departure crashes on state routes in Washington. Field study shows that though weak spots exist, overall lane marking conditions on the surveyed segments are compatible with the lane detection function of ADAS.

Kentucky Transportation Center A3 - Kentucky Transportation Cabinet AB - The Kentucky Transportation Cabinet (KYTC) is responsible for inspecting, maintaining, and improving 27,000 centerline miles of pavement. Given the vastness of the state's transportation network, KYTC needs a robust method for prioritizing pavement preservation projects. The Cabinet has relied on pavement condition ratings, data collected using Laser Crack Measurement Systems, and input from district-level staff to prioritize these types of projects. But this approach over-looks information that should be considered, such as factors related to safety, mobility, and geographic context. To resolve these shortcomings, Kentucky Transportation Center (KTC) researchers worked with KYTC subject-matter experts to develop the Enhanced Pavement Prioritization Index (EPPI). This index, partially modeled on methods adopted by other states, can be used to approach project prioritization more holistically. Potential projects are scored on 10 final factors after testing eliminated two variables due to data issues. The factors are grouped into three categories - Condition, Mobility, and Safety. Weights were assigned to each factor through the Analytic Hierarchy Process. Two factors are included in the Condition category: Pavement Distress Index and Highway Performance Monitoring System (HPMS) Cracking %. The Safety category also has two factors: Mean SCRIM Coefficient (MSC) and Rutting. And the Mobility category includes six factors: Average Daily Traffic, Average Daily Truck Traffic, Snow and Ice Priority System, Truck Route, Functional Classification, and the Criticality Index. The EPPI can be refined by KYTC over the next several budget cycles as it is put into practice ranking potential pavement projects.

In recent years, the use of polymer matrix composite materials as primary structural components has risen, especially in the general aviation (GA) industry. The use of composites not only results in weight savings, but also reduces part counts, joining operations, and results in significant savings in assembly, storage, and inspection. However, joi ...

Federal Aviation Administration. Office of Aviation Research A4 - Shyprykevich, Peter AB - In recent years, the use of polymer matrix composite materials as primary structural components has risen, especially in the general aviation (GA) industry. The use of composites not only results in weight savings, but also reduces part counts, joining operations, and results in significant savings in assembly, storage, and inspection. However, joining of some integral parts is still required. GA aircraft industry also uses bonded joints with bondline thicknesses much greater than the 0.01in. that was standard in aircraft bonded joints. For composites, there are two methods of joining: bonding and mechanical fastening. Of the two, adhesively bonding composite structures is the preferred method for a variety of reasons. There are several adhesive test methods that are used to determine the in situ properties of an adhesive joint for use in design. From these methods, ASTM D 1002, D 3165, and D 5656 were evaluated in this investigation with the substrate materials of 2024-T3 phosphoric anodized aluminum, carbon/epoxy quasiisotropic laminate, and fiberglass/epoxy quasi-isotropic laminate. Bondline thicknesses from 0.010-0.160 inch were evaluated for three paste adhesive systems using different test methods and substrate materials. The apparent shear strength given by the test methods investigated was found to be highly dependent on adherend bending stiffness, which directly effects the peel stress distributions in the adhesive layer. Thin-adherend specimens, regardless of bondline thickness, yielded lower apparent shear strengths than the thick adherend specimens and gave misleading information when comparing the apparent shear strengths of different adhesive systems. The adhesive shear-stress behavior was characterized over the range of bond thicknesses and environmental conditions and several recommendations and correction factors were offered for the thick-adherend test method.

Department of Transportation. Federal Aviation Administration. Office of Aviation Research AB - This collection of papers is a product of Task 11C of the Federal Aviation Administration (FAA) Aircraft In-flight Icing Plan. The papers are of two types. Industry users of icing simulation tools (facilities and computer codes) contributed articles describing how icing simulation methods are used in the design process and the certification process by their industry segment. These contributions include discussion of limitations of current tools and of gaps arising from differences between simulation needs and current capabilities. A table summarizing gaps noted by different industry users and recommendations for improvement is included in Appendix C to this report. Examination of the table reveals several major concerns. One such concern is the development of criteria and validation data, as necessary, for acceptance of simulation tools in certification. A large number of recommendations are listed for icing analysis computer codes. Increased use of these codes is attractive to industry in part because of their potential for improvements in cost/flow time in the design and certification processes. Issues of validation data and acceptance criteria are recognized as especially relevant to icing analysis computer codes. Providers and developers of icing simulation tools contributed articles summarizing the capabilities currently available in their respective areas. They address issues such as range of capabilities, accuracy, repeatability, and ease of use. They also list limitations of the simulation methods in terms of how well they function with respect to their stated purpose and how well they simulate natural icing encounters.
