Team:   Pavement Design and Construction Team [HRDI-20]
Program:   Innovative Pavement Research and Deployment
Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   Develop a fundamental model for the compaction of hot-mix asphalt. The project has been initiated and it involves identifying potential models, relating model parameters to the lab and the field, selecting a suitable model, sensitivity analysis, verification, and finally delivery. This will also require coordination with efforts at the development of new roller equipment with intelligent compaction capabilities.
Goals:   The key project objective is reliable and effective pavement design.
Product Type:   Research report
Expected Benefits:   The expected benefit is a fundamental understanding of why compaction is important to pavement performance and what factors need be considered to optimize inplace density, given the constituents of a given mix and other influencing factors, such as environment. The model may provide the ability to relate lab and field compaction. This should allow for improvements to be realized in the construction process that will contribute to extending pavement performance. The model should augment other ongoing efforts in the development of intelligent compaction roller equipment.
Deliverables: Name: Research report.
Product Type(s): Research report
Description: The deliverable is a report that describes the approach used to obtain the objective of developing a mathematical model that simulates the process of asphalt concrete compaction, and implementation of that model in a three-dimensional Finite Element Computational Platform.
