In Texas, and most of the U.S., Class F fly ash is the most used supplementary cementitious material (SCM) due to the many benefits it provides to concrete. In recent years, the availability of Class F fly ash has decreased as many coal-fired power plants have shut down. Plants that have not shut down are required to install various emission control systems...

Bridge load rating assesses the safe live load carrying capacity of an existing or newly designed structure. In addition to load rating with previously defined standard load rating vehicles, the Federal Highway Administration issued additional guidance to states related to rating requirements for all the bridges with respect to specialized hauling vehicles and...

The accurate characterization of the in situ aging of asphalt pavement materials over the service life of the pavement is of utmost importance to the implementation of mechanistic empirical (ME) pavement design and analysis methods. The TRB National Cooperative Highway Research Program's NCHRP Research Report 973: Long-Term Aging of Asphalt Mixtures...

The project investigated the ability of CV2X and DSRC communication systems to accurately send and receive data between vehicles which have lost their line-of-sight due to occluding obstacles. A propagation model to predict received radio power is developed using WinProp. The power prediction from the model is combined with packet reception data from actual...

Edge lane roads (ELRs), also known as advisory bike lanes or advisory shoulders, are a type of shared street where two-way motor vehicle (MV) traffic shares a single center lane, and edge lanes on either side are preferentially reserved for vulnerable road users (VRUs). This work comprises a literature review, an investigation of ELRs’ operational...

To prevent roadway departure crashes, rumble strips have been installed on Louisiana’s two-lane highways. This study investigated the impact of rumble strips on 1,593.09 miles of two-lane highways in Louisiana, on which centerline rumble strips (CLRS) and shoulder rumble strips (SRS) were installed between years 2010 and 2016. The comprehensive evaluation...

Run-off-road traffic crashes account for almost one-third of the deaths and serious injuries each year on U.S. highways. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 296: Guidelines for Cost-Effective Safety Treatments of Roadside Ditches provides new proposed design guidance for the configuration of ditches adjacent to...

This project studied the performance of geotextile-reinforced test sections when compared to an unreinforced case to assess benefit in terms of an extension of the life of the pavement. A single test track was constructed in an indoor test facility and contained two test sections with a reinforcement geotextile (woven and non-woven) while the third section was...

Municipalities across Minnesota have turned to Complete Streets in an attempt to develop more usable roads for their residents. This report investigates how Complete Streets are reshaping one Minnesota community. In 2013, Richfield, a suburb of Minneapolis, enacted a particularly innovative Complete Streets policy. Known locally as "Richfield Sweet Streets...
