Develop Nondestructive Rapid Quality Assurance / Quality Control Evaluation Test Methods and Supporting Technology

What Was the Need?

Construction variability and isolated defects can be the limiting factors in a pavement’s life. Ensuring quality construction of pavements currently uses small sample sizes, often missing defect areas. New innovations are needed to ensure attainment of specification requirements over the entire newly constructed pavement area while minimizing disruption to traffic.

Project Summary

The research team will determine new innovative methods for characterizing pavement materials to ensure specification compliance using nondestructive technologies. Such technologies allow for minimal traffic disruption, increased level of testing coverage, and potential for increased pavement life. TTI will research technologies to address elements of both flexible and rigid pavement construction. The research team will verify the compacted material density and mechanical properties of a flexible base course using nondestructive testing and mechanical based models. This project will include rapid quality measurements during asphalt mixture compaction. This project will include roller-based and post-compaction nondestructive tests to quantify roller compaction effort applied and evaluate final in-place density.

For rigid pavements, this project will explore nondestructive techniques for evaluating effective curing of the concrete mixture. The focus elements included in this project, if demonstrated to be feasible and implementable, will make assuring quality pavement construction more timely and reliable with minimal disruption to traffic.
