Research Section

Mission

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:

Missouri Systemic Countermeasures to Improve Pedestrian Safety

Missouri Department of Transportation (MoDOT) has successfully implemented systemic safety countermeasures in the past to reduce fatal and serious injury crashes related to roadway departure. MoDOT initiated this research project to address the increasing trend in pedestrian fatalities and serious injuries in Missouri. The focus of the project is t...

Implementation of Data Quality Assurance (QA) for Innovative Technologies at MoDOT

Intelligent construction technologies (ICTs) combine modern science and innovative construction technologies. The goal of ICT is to improve the quality of construction, save costs, and improve safety. The ICTs described in this report include intelligent compaction (IC), paver-mounted thermal profiler (PMTP) equipment, and dielectric profiling syst...

Implementing the LWD for MoDOT Construction Acceptance of Unbound Material Layers

Conventional density-based methods of compaction quality assurance (QA) using nuclear density gauges (NDG) have been in practice for many years. However, NDG testing has become less desirable because of safety, regulatory, and cost concerns. In addition, density is not a direct input to the structural design of the pavements and is not directly lin...

Effectiveness of Speed Management Methods in Work Zones

Management of speed is a significant component of any strategy to reduce work zone crashes. The objective of this study is to investigate the effectiveness of speed management countermeasures, such as speed display trailer, speed display trailer with red and blue lights, work vehicle with red and blue lights, and active and passive law enforcement,...

GFRP Reinforced Bridge Barriers: Numerical Modeling

This research examines the numerical modeling of GFRP reinforced concrete bridge barrier under static and impact load. The GFRP configurations were designed to fit into the existing MoDOT Type D barrier structures. The constructability of the GFRP reinforcement was also taken into consideration. Both static and dynamic loading were modeled to exami...

Performance of Wicking Geotextile (H2Ri) to Mitigate Pavement Pumping - Phase 2

Pumping is one of the major factors contributing to pavement failures. This reduces pavement life, affects road safety, and increases maintenance costs. Existing methods that are used as drainage systems can drain gravitational (free) water under saturated conditions but not the capillary water under an unsaturated condition. The objective of this ...
