As one of the most important concerns on concrete, the durability of concrete needs to be robustly assessed with a series of screening tests. Specifically, the chloride and sulfate durability need to be further evaluated. FDOT has elected to move forward with the surface resistivity (SR) test method based on AASHTO T358 and bulk resistivity (BR) test method based on AASHTO TP119 for chloride durability assessment. For the sulfate durability assessment, FDOT elected to move forward with the rapid sulfate permeability test method based on a modified ASTM C1202 test method for Rapid Sulfate Permeability Test (RSPT). In order to widely deploy these test methods for chloride and sulfate durability, we need to choose appropriate thresholds. In addition, to fully assess the durability of concrete mixes with Supplementary Cementitious Materials (SCM), 56-day result need to be obtained and its correlation with 28-day result need to be studied. The research team has performed SR, BR, RSPT, and length change test (ASTM C1012) for 31 selected concrete mixes and the thresholds were selected and proposed for SR, BR, and RSPT tests. A series of prediction equations were also developed to predict the 56-day result based on 28-day testing result.

The objective of this research study is to assess speeds driven by motorists in Missouri freeway work zones, including average speeds, 85th percentile speeds, maximum speeds, and levels of work zone speed limit compliance and noncompliance. The research methodology to meet this objective includes a literature review and field study to collect and measure work zone speed data. The field study included the measurement and analysis of speeds (with and without a work zone) for almost 5.5 million vehicles at five interstate work zones in Missouri. Probe data from HERE were also analyzed, and crashes corresponding to the dates and locations of the data collection were reviewed. Results from the literature review indicate that previous studies generally found various levels of speed limit compliance in work zones. The crash review identified four crashes across all sites during the time of the data collection, one of which was due to excessive speed. Overall, results from the analysis of field data and HERE data indicate prevalent speeding in Missouri work zones. While vehicle speeds were lower with the work zone compared to non-work zone conditions, speed variation with the work zone in place also increased. The presence of workers in the closed lane separated by channelizers on I-44 was associated with lower speeds and greater speed limit compliance. Possible strategies to reduce speeds and improve speed limit compliance in Missouri work zones could include law enforcement presence, speed feedback trailers, public outreach campaigns, and reviewing existing policies on setting work zone speed limits.

Federal Highway Administration AB - Following its adoption of the new AASHTO Bridge Element Inspection Manual, the Florida Department of Transportation (FDOT) has been collecting bridge element condition data in order to use the AASHTO’s Bridge Management (BrM) software. Now, to aid the Department in satisfying the various federal requirements and prepare for anticipated changes at the national level in the bridge inspection and management standards, the FDOT needs to re-calibrate the core BrM models and tools, including the element deterioration models, risk models, the translator model, and cost models. This study has developed deterioration models for forecasting bridge element condition within the analytical framework of the BrM and explored the revision of the FDOT’s environmental classification scheme for its bridge inventory. Considering the natural and man-made hazards that are unique to Florida, risk models were developed by estimating at each bridge location, the likelihood of occurrence of the hazard, the likelihood of service disruption, and costs of the associated consequences. To enable conversion of bridge element condition data to the FHWA’s NBI ratings, a new NBI Translator was developed, with the focus on five bridge components: deck, superstructure, substructure, culvert, and channel. Finally, in response to the decreasing availability of cost data for bridge maintenance, repair and rehabilitation (MR&R) activities, this study developed unit costs based on the available historical costs (bridge work orders and the bid unit prices) and also formulated a methodology for developing crew-based cost estimates.

UAV-based measurements offer non-contact alternative to traditional field methods in hazardous environments or high-flow conditions. A comprehensive literature review of 522 publications (2010–2024) was conducted and found that reported errors showed radar-based WSE and hyperspectral/multispectral bathymetry as the most accurate, while PTV showed the highest accuracy with a mean absolute percentage error (MAPE) of 10.7%, while the surface velocity method (SV) yielded the lowest discharge error (MAPE = 12.4%). For the field studies in the next phase, six field sites were selected from 21 candidate locations, to represent diverse channel and hydrologic conditions. Five sites were surveyed using UAV photogrammetry, LiDAR, PIV/PTV, and sonar-based bathymetry. Discharge was estimated using GM and surface-velocity approaches (SV). GM used LiDAR geometry, bathymetry, roughness, and slope, while SV used PIV/PTV at all sites. UAV-based discharge estimates showed 22.2– 25.3% difference relative to USGS rating curves. SV produced more consistent accuracy across sites, while GM was highly sensitive to roughness and geometry. SV is recommended when field time is limited, and GM when detailed channel data are available.

This data gap limits the effectiveness of smart work zone deployments and emerging connected vehicle applications. This study evaluated device-based location technologies for highway work zone applications by comparing Global Navigation Satellite System (GNSS) and Bluetooth Low Energy (BLE) approaches. Results indicated that BLE devices relying on crowdsourced networks produced inconsistent reporting and large location errors, particularly in rural areas, while GNSS devices provided more stable and temporally consistent data but involved tradeoffs related to cost, battery life, and data accessibility. To address these limitations, the research developed the WZ-Gateway Node, an open-source prototype that utilizes shared communication to reduce recurring costs. Complementing the hardware, the MU Worker Presence Platform was developed to process device-level data into validated worker presence attributes. By applying spatial buffering and activity classification logic, the platform filters false positive s and protects worker privacy while accurately associating field activity with work zone characteristics. Field evaluations confirmed the platform’s ability to generate WZDx-compliant feeds with real-time, verified worker presence information.

Department of Transportation AB - The AASHTO Committee on Bridges and Structures has approved the updated ACI CODE-318, 2019 edition (ACI CODE 318-19,) into the 10th edition of the AASHTO LRFD Bridge Design Specifications. This would allow the adoption of screw anchor designs that benefit from rapid, reliable, and simplified installation procedures. However, the ACI CODE approach has been shown to be too conservative in typical FDOT applications because it does not account for the confinement effect caused by the metal baseplate's compressive force in the concrete breakout cone. Furthermore, previous studies have shown that the predominant failure mode of screw anchor is a combined failure with a much higher breakout capacity than the concrete breakout failure limited by the ACI CODE. Therefore, this research provides an experimental investigation of the failure mechanism and appropriate confinement effect of screw anchors used in typical FDOT applications. Results indicated that the screw anchors’ breakout resistance consistently exceeded nominal strength predicted by ACI CODE and the required design loads. It is recommended that FDOT permit the use of screw anchors because it reduces installation cost and time because there is no additional adhesive cost or need to wait for adhesive to cure. It is also recommended that FDOT adopts a strength reduction factor of ϕ = 0.75 for both design purposes and when evaluating future test results for screw anchors instead of the ACI CODE ϕ = 0.65.

These included: (1) johnsongrass control, (2) willow control, (3) bindweed control, (4) broadleaf weed control, (5) sandbur control, (6) seeding Plains bluestem, and (7) planting ground covers other than grass. As a result, the use of herbicides for roadside maintenance has increased dramatically in the period 1967 to 1981. In 1976, approximately 300 acres were treated with herbicides. By 1980, the total exceeded 109,000 acres. Meanwhile mowing has been reduced substantially, from 229,729 acres in 1976 to 157,912 acres in 1980. Cost savings have been especially significant. Mowing costs have continued to rise each year to $11.56 per acre in 1980, while chemical costs have decreased in the past three years to $7.65 per acre in 1980, a savings of almost $4.00 per acre. The selective control of johnsongrass along Oklahoma highways can be achieved with applications of MSMA (monosodium methanearsonate), or DSMA (disodium methanearsonate). Willows less than 4 to 5 inches in diameter, can effectively be controlled during the dormant season (February-March) by a basal bark treatment of 2,4-D low volatile ester in diesel oil (ratio 1:25). Two annual applications, for 2 to 3 years, made with 1 quart of 2, 4-D low volatile ester (4 lb. ai/gal) in water at 40 gpa, can eliminate 75% or more of the perennial bindweed from our roadsides. The preemergence application of Aatrex 4L, or Abatrex 0W, has provided 95 to 100% broadleaf control, and most annual grasses. Sandburs can be effectively eradicated with 2 to 3 annual applications of DSMA. The lack of precipitation during the year of establishment, resulted in very little success with Plains bluestem and Japanese honeysuckle, in producing erosion resistant ground cover.
