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:
Pavement Roughness Measurement Using Android Smartphones: Case Study of Missouri Roads and Airports
To address a need for simple and low cost tools to facilitate the evaluation of airport pavement condition for smaller airports with limited resources, a study was undertaken to evaluate an android smartphone application for use in assessing airport pavement condition.
Unmanned Aircraft Systems: An Overview of Strategies and Opportunities for Missouri
This research explored the adoption of UAS technology at the national and state levels – focusing on the role of transportation agencies, activities, policies, and strategies promoting safe UAS operations and economic growth.
Field Implementation of Rubberized Chip Seal
Chip seals have been widely used as a pavement maintenance surface treatment due to its competitive cost and construction time. Recently, the research team developed a rubberized chip seal where natural aggregate is replaced with crumb rubber obtained from recycled tires.
Characterization and Performance of Zero-Cement Concrete
This study investigated the feasibility of using five different types of class C fly ashes (FAs) sourced from Labadie, Jeffrey, Kansas City, Thomas Hill, and Sikeston power plants in the state of Missouri to synthesize zero-cement concrete (ZCC) for different structural and repair applications.
Field Implementation of Super-Workable Fiber-Reinforced Concrete for Infrastructure Construction
A fiber-reinforced super-workable concrete (FR-SWC) made with 0.5% micro-macro steel fibers and 5% CaO-based expansive agent was used for the new deck slab of Bridge A8509.
Performance Characteristics of Modern Recycled Asphalt Mixes in Missouri, Including Ground Tire Rubber, Recycled Roofing Shingles, and Rejuvenators
Roller Compacted Concrete for Rapid Pavement Construction
The main objective of this research was to develop high-performance Roller Compacted Concrete (RCC) with enhanced solid skeleton to secure greater workability, mechanical properties, and frost durability. The study involved the development of a stepwise mixture design methodology to select aggregate proportioning and particle-size distribution of c...
Field Implementation of High-Volume Recycled Materials for Sustainable Pavement Construction
The objective of this study was to evaluate the feasibility of producing sustainable concrete materials for rigid pavement construction using high volume of recycled materials. The goal was to replace 50% of all solid materials in the concrete with recycled materials and industrial by-products.
Field Implementation and Monitoring of Behavior of Economical and Crack-Free High-Performance Concrete for Pavement and Transportation Infrastructure Constructions – Phase II
The aim of this project was to validate findings of the Phase I research through field implementation and develop guidelines for the use of Eco-HPC for sustainable transportation infrastructure construction.
