  • Abstract:
    Current roadway quality control and quality acceptance (QC/QA) procedures ; for Louisiana include coring for thickness, density, and air void checks in hot ; mix asphalt (HMA) pavements and thickness and compressive strength for ; Portland cement concrete (PCC) pavements. In-situ devices, such as the ; Light Falling Weight Deflectometer (LWD) and Portable Seismic Pavement ; Analyzer (PSPA), are able to measure the modulus of the surface layer of a ; pavement quickly. These devices are non-destructive and portable, which ; allow for fast in-place determination of pavement properties, resulting in a ; sizable data set in a small amount of time. This would give the Department a ; tool for checking the consistency of in-place pavements and supplementing ; current QC/QA practices. This research will determine the ruggedness and ; consistency of each device as well as develop an operating procedure for ; running tests. Also, it will compare in-situ modulus values and mechanical ; properties measured in the lab. This research is intended to serve as a ; guide for further research regarding the LWD and PSPA.
