Research Section


We deliver knowledge solutions and innovations so that MoDOT can make informed decisions. Research staff administer contract research to outside organizations to solve organizational challenges.

Research projects are focused on how MoDOT can change processes, products or materials in order to do our jobs in the most efficient and economical manner.

The Research Section falls under the Construction and Materials Division within MoDOT and is located in the Central Laboratory building.

What We Do

We develop an annual research program, focusing on strategic areas such as Safety, Bridges, Pavements, Materials, Geotechnical Issues, Erosion Control, Maintenance, Multimodal Transportation, Best Practices and Customer Satisfaction.

The Research Section is also responsible for other activities:

Design Coefficients of Friction for MoDOT PTFE Bearings

This report evaluates the design coefficients of friction for polytetrafluoroethylene (PTFE) bearings, identifying key influencing parameters through a literature review and a detailed test program. Seven parameters were studied: PTFE material and surface types, size, contact pressure, temperature, sliding speed, and surface contamination. The anal...

Intermediate Bents – Calculation of Restraint Factor

This report investigates the restraint at the top of the column of non-integral intermediate bents with closed diaphragms, a common connection configuration utilized by the MoDOT. Although closed diaphragms inherently possess some level of rotational restraint, the current design approach considers this type of connection as free, resulting in the ...

Identification of a Response and Rescue Network for the St. Louis Region

Emergency preparedness and response are crucial for mitigating the impact of natural disasters such as earthquakes. The St. Louis metropolitan region is vulnerable to earthquakes in the New Madrid and Wabash Valley Seismic Zones. This study focuses on understanding and addressing transportation impacts of an earthquake in the St. Louis region. An o...

Consultant Support for Intelligent Compaction and Paver-Mounted Thermal Profiling Projects in 2022-2023

MoDOT's Intelligent Compaction (IC) and Paver-Mounted Thermal Profiling (PMTP) projects from 2017 to 2021 showed improvements in paving quality, leading to an extension of these projects into 2022 and 2023. The aim was to procure consulting services to maintain the success of IC-PMTP projects. The project spanned 26 months, from March 2022 to April...

Transportation Infrastructure Asset Monitoring Through the Industrial Internet-of-Things

The Internet-of-Things (IoT) is a rapidly growing area of wireless communication technology that allows devices to communicate with computers and humans via the Internet. This technology goes far beyond simply connecting devices to the internet, it creates opportunities to combine data from these devices with automated systems for the purpose of an...

Comprehensive Data Analysis for AMPT Tests on MO 740 and Hwy 54

In this study, the S&T research team conducted comprehensive data analysis from the Asphalt Mixture Performance Tester (AMPT) samples collected in the Highway 54 and MO 740 projects. The MO 740 project in Boone County contained test sections with five mix designs, i.e., control mix, ground tire rubber (GTR)-modified mixture, and three mixtures ...
