  • 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.
