The research team investigated the acquisition of high-resolution images with American Association of Highway and Transportation Officials (AASHTO) standard MP47 and created a tool for viewing the vendor’s data and labeling different distresses on three pavement types (Asphalt Concrete Pavement (ACP), Jointed Concrete Pavement (JCP), and Continuously Reinforced Concrete Pavement (CRCP), respectively). 2D/3D images were selected carefully to include diverse pavement defects to be annotated. For each type, the selected images were labeled with bounding boxes to manually locate and mark the pavement surface distresses. Segmentation masks were provided for a small portion of images for potential applications. A comprehensive image library was established in the AASHTO standard data format, capturing diverse pavement conditions and surface types in Texas.

Federal Highway Administration AB - The development of a national standard data format for two-dimensional/three-dimensional (2D/3D) pavement surface images and Artificial Intelligence (AI) Machine Learning (ML) in Computer Vision adopted by AASHTO and embraced by state DOTs has provided TxDOT the opportunity to develop new methods for automated pavement condition assessment. This research implements automated pavement condition evaluation using 2D/3D surface imagery and Artificial Intelligence. A comprehensive image library was established in the AASHTO standard data format, capturing diverse pavement conditions and surface types in Texas. The dataset includes 5,892 2D/3D image pairs and associated labels for Asphalt Concrete (ACP), 7,750 for Jointed Concrete (JCP), and 5,776 for Continuously Reinforced Concrete Pavement (CRCP). These correspond to 10,885, 16,943, and 13,779 individual distress instances, respectively, as defined by the TxDOT Pavement Management Information System (PMIS) for a total of 19,418 images. Neural network models such as YOLO (You Only Look Once) series were trained on the established library datasets for generalization and robustness of pavement distress measurements. Leveraging vision-based AI and ML models, the system automatically detects and measures surface distresses, achieving a mAP50 of over 0.80 for ACP, 0.70 for JCP, and 0.75 for CRCP on the validation datasets. These models were integrated into practical tools for calculating PMIS distress scores and delivered via a dedicated software application for TxDOT. A pilot study was implemented using both the library and vendor-collected field data in 2024 to validate the efficacy of the proposed methods. The research concludes with actionable recommendations and a strategic roadmap designed to transition these findings into full-scale operational implementation within TxDOT’s pavement management system.

Bureau of Materials and Physical Research A3 - United States. Department of Transportation. Federal Highway Administration AB - This study investigated the potential pavement performance, resiliency, cost-effectiveness, and environmental efficiency of incorporating locally sourced Illinois aggregates into stone-mastic asphalt (SMA) through an integrated laboratory and full-scale assessment. SMAs were designed using local aggregates with different lithology and durability levels. The potential performance of SMAs with local aggregates was benchmarked against those using imported aggregates. Optimized SMA designs with local aggregates were developed, and aggregate degradation was quantified at successive stages of mixture production, construction, and loading. Full-scale pavement sections were built; six SMAs were placed on top of a 2 in hot-mix asphalt binder layer overlaying continuously reinforced concrete pavement. The sections were instrumented and tested using the Illinois Accelerated Pavement Tester. Varying loading configurations and temperatures were applied to measure the response of each section. Then, the pavement was loaded under constant tandem loads at approximately 80°F. Pavement performance was interpreted using SMA strains and surface rut depth. Peak transverse tensile strain proved effective for characterizing viscoelastic recovery and distinguishing mixture behavior under repeated loading. The strain-based recovery measurements were incorporated into a viscoelastic-based rutting progression framework and used to compare SMA performance. Aggregate breakage was measured and was primarily associated with compaction and laboratory loading processes, whereas accelerated traffic loading produced negligible additional degradation, indicating that aggregate stability was governed by mixture design and construction rather than in-service loading. Life cycle assessment and life cycle cost analysis suggested that using local aggregates is not only cost effective but also reduces negative environmental impacts while maintaining SMA’s expected performance and resiliency. Through integrated laboratory mixture design and performance testing, full-scale pavement construction, accelerated pavement testing, instrument responses, and life cycle cost analysis and environmental assessment, this study demonstrated that SMA incorporating locally sourced Illinois aggregates could achieve performance comparable to conventional SMA while reducing costs and environmental impact. Hence, this study recommends designing and adopting 50 gyration SMA with local aggregates.

It served as the Secretary of Transportation’s initial policy blueprint for the restructuring process later carried forward by the United States Railway Association. It is the first part of a three-volume set: Volume I → methodology, criteria, policy logic Volume II, Part 1 → zone results (Northeast states) Volume II, Part 2 → zone results (Midwest + southern states) Volume I found that the region’s railroad system suffered from severe physical deterioration, financial insolvency, excess route mileage, duplicated facilities, and declining competitiveness. It recommended consolidating high-volume interstate routes, modernizing core corridors, coordinating operations among carriers, preserving financially justified local service, and addressing excess lines through abandonment, subsidy, or combined rail–motor service. In context, the report provided an analytical foundation for USRA’s later Preliminary and Final System Plans, which translated these recommendations into Conrail’s network, property transfers, abandonments, and subsidized service arrangements. Overall, the report framed the 3R Act restructuring around a central goal: preserving essential rail service while creating a more efficient, financially viable, and publicly affordable rail system.

Research Management Center AB - Corrosion of steel tendons in post-tensioned bridge girders can lead to section loss and, if left unaddressed, may result in strand rupture and a corresponding reduction in girder strength. In the state of Florida, a number of remedial measures have been explored and implemented to address such issues, including the use of corrosion inhibitors to mitigate strand corrosion. Impregnation of corrosion-inhibiting fluids into grouted post-tensioned tendons has been shown to be effective in reducing strand corrosion. However, the impregnation of these fluids may also have the potential to adversely affect the bond between steel tendons and the surrounding grout. Past studies involving pull-out tests of unstressed strands in grout have indicated that a reduction in bond strength may result from the use of corrosion-inhibiting fluids. However, relatively little research has been carried out to determine the effect that such fluids may have on the flexural performance of full-scale post-tensioned concrete bridge girders. AB - In this study, full-scale experimental flexural tests of post-tensioned concrete beams with grouted tendons were performed to directly evaluate the extent to which impregnation with a corrosion-inhibiting fluid might affect either the strength level performance (nominal flexural strength) or the service level performance (crack severity) of such beams. Variables that could potentially influence the bond condition between tendon and grout, due to the presence of corrosion inhibitor, were incorporated into the experimental test program. These variables included tendon size (6-, 12-, and 19-strands), tendon profile (straight, draped), grout type (prepackaged, plain cement, legacy), duct type (metal, plastic), age of corrosion inhibitor impregnation at the time of testing (0.5 months to 2.5 months), and the beam condition when initially impregnated (uncracked, cracked). Five groups of beams were tested under four-point bending to evaluate both strength level nominal flexural resistance and service level crack behavior. AB - At the strength load level, test results and corresponding analyses indicated negligible differences (less than 2%) between the nominal flexural resistances of newly constructed beams treated with corrosion-inhibiting fluid and the nominal flexural resistances of corresponding untreated control beams. In regard to service load levels, a “cracking load” level was defined in this study as the applied load that produced a calculated tensile stress of 12√fc , at the extreme tension fiber, consistent with the ACI 318 definition of a cracked section. This higher stress level was selected to ensure that cracking would be observed while remaining reasonably aligned with AASHTO LRFD serviceability limits, which typically allow 6√fc , under Service III conditions. At the defined cracking load level, treatment with corrosion inhibiting fluid produced negligible changes in observed patterns of crack spacing and crack frequency. Conversely, alternate analyses of beam cracking produced mixed results wherein a limited number of tests indicated that impregnation of corrosion-inhibiting fluid was associated with moderately increased crack severity. It must be noted, however, that the presence of an adequately impregnated volume of corrosion-inhibiting fluid into a tendon could presumably protect such a tendon from any increased exposure risk that was associated with increased cracking.

Having agile monitoring methods to identifying emerging issues and challenges can provide data to transportation agency decision makers to refine maintenance of traffic plans and inform future designs. This study developed techniques to fuse a multitude of data sources including connected vehicle speeds, connected vehicle hard-braking events, crash reports, digital alerts, commercial vehicle dash camera images, into a weekly interstate work zone report that gives stakeholders a holistic overview of their work zone operations and allowed for easy identification of opportunities for improvement. Approximately 249 weekly work zone reports were generated and distributed to approximately 100 stakeholders across the state on an approximately weekly basis. These reports provide an at-a-glance view of statewide, district, and route mobility, crash data, hard-braking, and most recently dash camera images to contextualize the heatmaps.

Federal Highway Administration AB - Work zones along interstates often have increased congestion and crash rates when locations are close to or over capacity. Having agile monitoring methods to identifying emerging issues and challenges can provide data to transportation agency decision makers to refine maintenance of traffic plans and inform future designs. This study developed techniques to fuse a multitude of data sources including connected vehicle speeds, connected vehicle hard-braking events, crash reports, digital alerts, commercial vehicle dash camera images, into a weekly interstate work zone report that gives stakeholders a holistic overview of their work zone operations and allowed for easy identification of opportunities for improvement. Approximately 249 weekly work zone reports were generated and distributed to approximately 100 stakeholders across the state on an approximately weekly basis. These reports provide an at-a-glance view of statewide, district, and route mobility, crash data, hard-braking, and most recently dash camera images to contextualize the heatmaps AN - dot:90504 DO - https://doi.org/10.5703/1288284318581 ET - Final Report KW - Crash rates KW - Data sharing KW - Traffic congestion KW - Work zones KW - Braking KW - Connected vehicles KW - Interstate transportation LA - English PB - Purdue University.

Department of Transportation AB - This report examines the electrification of buses, vocational trucks, and construction machinery, as well as the impact of advancements in battery technology on this transition. The electrification of these vehicles and machinery, alongside rapid progress in battery development, is accelerating. This study provides a comprehensive review of current research on lithium-ion and sodium-ion batteries, evaluating their development status and the challenges to commercialization. A key objective of this study is to assess the progress of advanced battery development and its influence on the further commercialization of buses, vocational trucks, and construction machinery. Modeling suggests that within the next 7 to 12 years, batteries with energy densities of 500 Wh/kg and 1000 Wh/L will enable electrified construction vehicles and machinery to match or surpass the performance of current diesel-powered equipment. Electric buses are already commercially available and expanding globally, while electrified construction trucks and machinery have been successfully demonstrated in real-world projects across the U.S., China, and Europe. These electrified machines offer multiple advantages, including lower carbon dioxide (CO₂) emissions, improved efficiency, quieter operation, and reduced maintenance and energy costs compared to diesel-powered counterparts. Manufacturers are optimistic about market growth, particularly given the support of federal and state incentives aimed at reducing CO₂ emissions. Currently, the cost of electrified construction machinery remains relatively high. However, near-term cost projections are uncertain, as they depend not only on the comparative costs of diesel engines, batteries, and electric motors but also on the rate at which prices for electrical components decline in the near future.

The methodology included comprehensive literature reviews, an inventory of 49 global transit systems, seven case studies, and expert interviews to assess payment accessibility, technical rules, interoperability, and user privacy. The study found that current systems disproportionately burden low-income, unbanked, and disabled users through high complexity and lack of cash-equivalent options. To mitigate this, the report recommends designing and deploying a California Mobility Card (CMC). The CMC would be a reloadable, prepaid transportation card operating on an existing, widespread payment network, offering cash-equivalent anonymity, seamless cross system travel, and automatic access to discounts like fare capping.

Federal Highway Administration AB - Over the past 18 months, the team has performed several dozen after-action reviews of interstate work zones and the associated maintenance of traffic (MOT). These after-action reports generally contain the following information: Date, location, visual images, connected vehicle summary graphics, qualitative discussion of activity, and in some cases press releases or media posts. In general, these themes emerged: AB - 1.MOT plans in some cases do not accurately capture the geometry constraints placed by bridges, guardrail and or barrier wall. It is important that design reviews place careful focus on ensuring lane widths, shoulders, and shoulder treatments fit across the entire cross section of each phase or requests for design exceptions be initiated. In some cases, performing some type of LiDAR survey prior to design may assist MOT designers in effectively capturing more accurate location and dimensions of existing geometrics, particularly edge of pavement, edge of bridge, guardrails, and embankments. AB - 2.When lane shifts are initiated, the designers should examine the path of the vehicle at both the start and end of the transition. In some cases, the end of the transition occurs quite close to either a guardrail or narrow section of pavement. In some cases, either gentler transitions or additional horizontal clearance should be considered. AB - 3.There is relatively little dialog between the temporary traffic control contractors and designers on what are the best practices and requirements for implementing a change in MOT. AB - 4.To sustain this engagement between designers, and MOT contractors, it is recommended that selected projects include MOT review with design engineers, and contractor as part of the close out process to document lessons learned. AB - 5.Rolling slows downs have a role in MOT, but there appears to be inconsistent use of rolling slowdowns for short term closures. It is recommended that requirements for rolling slowdowns be identified in the MOT plans. If contractors are required to use rolling slowdowns not documented in MOT plans, they should be required to obtain approval from the Indiana Department of Transportation and notify the Traffic Management Center. AB - 6.Barrier walls are an important tool for MOT. However, their set up can have significant impact on traffic capacity and create queues. Project plans should define days/time periods these are permitted to be installed and/or removed.
