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:

Inlaid Pavement Marker Evaluation

The objectives of this study were to assess inlaid pavement marker (IPM) performance and estimate their safety effectiveness. IPM performance was evaluated through a count of marker presence and a feedback survey from participants who viewed dry and wet night videos of IPM sections in the St Louis area. The safety effectiveness of IPMs was evaluate...

Highway Safety Manual Training

The demand for knowledge and experience in data driven safety analysis has been increasing. This report documents a project to produce data driven safety training for MoDOT trainers. The project developed two training deliverables. The first was a full-day training for safety staff and engineers. This training covered the fundamentals of data drive...

Local Calibration of the Pavement ME for Missouri

The Missouri Department of Transportation (MoDOT) was one of the early adopters of the Mechanistic-Empirical Pavement Design Guide procedure and completed local calibration using the research grade software in 2009. The emphasis then was on establishing testing and field data collection programs, and calibrating for new designs, as adequate perform...

Performance-Based Specifications of Fiber-Reinforced Concrete with Adapted Rheology to Enhance Performance and Reduce Steel-Reinforcement in Structural Members

The main objective of this research is to propose novel materials for the construction and retrofitting of bridges, including Economical Crack-Free High-Performance Concrete (Eco-Bridge-Crete, or EBC) and Fiber-Reinforced Super-Workable Concrete (FR-SWC). The project seeks to optimize the coupled effect of fiber characteristics, expansive agent (EA...

Consultant Support for IC-PMTPS Projects

Due to the success of the MoDOT 2017 Intelligent Compaction (IC) and Infrared Scanning (IR) projects that demonstrated Quality Control (QC) improvements on 13 field projects, MoDOT established a plan that included further IC and Paver-mounted Thermal Profile Systems (PMTPS) projects in 2018-2019 with a goal of full implementation in 2021. To ensure...

Field Implementation of Compacted Concrete Pavement

The main objective of this research is to investigate the performance of Compacted Concrete Pavement (CCP) with special design features that can reduce construction cost and create a safe and durable surface texture. The CCP mixture was evaluated for key fresh properties, mechanical properties, drying shrinkage, and durability. Goals of this study ...
