Research Solutions: Evaluating Car Lane Dimensions in Work Zones, TPF-5(438), 2025
No full textThe goal of this project was to quantify the mobility and safety impacts of different combinations of lane width and shy distance to a barrier for a given paved width. The research team developed a device to measure lateral distance and derive speed, vehicle length/type, and headway information under day and night conditions. Data collected at 17 locations in Illinois, Michigan, and Wisconsin were used for the analyses. Lateral distance data of over a quarter of a million vehicles were used for the safety analysis. Extreme value theory (EVT) modeling was conducted to estimate the probabilities of right edge line encroachment and right barrier contact. Wider lanes were found to have decreased edge line encroachment and barrier contact, while wider shy distances were associated with increased edge line encroachment and decreased barrier contact. The speeds of over 125,000 free flow vehicles were used to quantify the mobility impact. Linear regression modeling was conducted to develop models for estimating free flow speeds in work zones. Work zone free flow speed increases with an increase in speed limit, lane width, and left/right shy distances to a barrier. A case study of a 55 mph posted work zone with two open lanes and barriers on both sides with an available paved width of 26 ft is presented. The results indicate that 11 ft lanes with 2 ft shy distances have a slightly lower probability of right barrier contact (for vehicles in the right lane) than 12 ft lanes with 1 ft shy distances while having a greater free flow speed. This research demonstrates how lateral distance can be collected and modeled along with speed data to assess safety and mobility impacts in work zones. Limitations of the study are acknowledged, and recommendations for future research are presented
Research in Progress: Evaluating Materials to Limit Water Intrusion on Bridge Decks, SPR-RE25(008)-8H-00, 2025

Research in Progress: Sharing Maintenance Innovations to Accomplish More with Less, TPF-5(548), 2025
Full text linkThe fourth phase of No Boundaries build upon its work to facilitate and support successful tech transfer of maintenance-related innovations among member states. These efforts will include hosting a twice-yearly in-person peer exchange for state representatives to meet and address their challenges and innovative maintenance solutions, supporting a variety of additional opportunities for learning and exchanging knowledge and developing marketing plans and case studies to document and highlight stories of successful tech transfer. In addition, No Boundaries will continue to build and maintain a searchable online database where maintenance innovations can be found and showcased by all state transportation agencies
Research Solutions: Using Eggshells as a Soil Stabilizer in Iowa Road Construction, TR-810, 2025
Full text linkWhile Iowa egg production is significantly important to the state economy and national market, large amounts of eggshells generated from Iowa egg industries remain unused as a value-added product. The primary objective of this study would be to explore and demonstrate the concept of using Iowa eggshells as bio-based, cementing materials to strengthen and stabilize frostsusceptible soils and improve the low quality of local aggregates presently used in Iowa pavement and gravel road applications. This will be achieved through the execution of the following primary tasks: (1) characterization of Iowa eggshells, (2) identification of treatment methods for producing high calcium oxide or quicklime (CaO) content eggshell powder (ESP), (3) evaluation of constructability and performance of geo-material stabilization techniques using high CaO content ESP through comprehensive laboratory assessment, (4) proof-of-concept demonstration of eggshell-based geo-material stabilization techniques for use in Iowa pavements and gravel roads, and (5) development of implementation recommendations for real-world applications. The successful outcomes of this research will be new value-added products derived from Iowa eggshell waste, which could be used for improving performance and sustainability of transportation infrastructure systems, eventually enhancing environmental quality as well as producing substantial economic benefits for the State of Iowa
