Brief Description of Research Project |
|
The proposed project will investigate cost-effective, rapid pavement construction techniques that can reduce construction cost and duration. The roller roller-compacted concrete (RCC) with or without an asphalt topping will be investigated in this project. These types of pavement materials are usually zero slump concrete mixtures placed with conventional or high-density paving equipment, and then compacted with rollers. |
|
Describe Implementation of Research Outcomes |
|
The research can contribute to the development and implementation of new mixture design methodology and quality control tools for the design and construction of concrete pavement using RCC. The use of RCC can accelerate concrete pavement construction and improve mechanical and long-term performance, leading to reduced life-cycle cost of the transportation infrastructure. Meanwhile, the outcomes of the research can provide guidelines for the selection of concrete constituent materials, mixture optimization methodology, and performance-based specifications, and construction guidelines of RCC pavement. Based on the results obtained from this study, the recommendations can be made for RCC field implementation. |
|
Impacts/Benefits of Implementation |
|
The investigation also involved the evaluation of the effect of the binder content, AEA dosage, Vebe workability level, mixer type, and compaction energy on mechanical properties and durability. The durability results of the developed RCC mixtures were compared to those of three reference mixtures developed in the field and from previous laboratory research carried out by the authors in collaboration with MoDOT in 2013. Based on the findings of this research, the main findings are summarized in the report. |
