FWD Testing and Backcalculation of Rubblized and Fractured Slab PCC Pavement Moduli

This study will investigate the material properties of rubblized concrete under HMA layers for design purposes. The project recently done on I55 in Pike County, as well as the project yet to be done on I-59 in Forrest and Jones Counties, will be used for the research on rubblization. A break-and-seat project is to be done on I-55 in Tate County, which will be investigated as part of this study. Dynatest will do field FWD testing and recommend any further test protocols for the rubblized/break-and-seat concrete.
