Ground Penetrating Radar Evaluation of New Pavement Density Paving Project - SR 539 in Lynden, WA
The objective of this project was to map pavement surface density variations using dielectric measurements from ground penetrating radar (GPR). The work was carried out as part of an Asphalt Intelligent Compaction demonstration project on SR 539 in Lynden, WA. This demonstration was part of a larger WSDOT project entitled, "Lynden-Aldergrove Port of Entry Improvements." The research found that comparing the GPR dielectrics and core air void data showed no significant correlation. It was speculated this lack of correlation could be due to a density gradient within the 4-inch asphalt depth, and the fact that the GPR equipment only captures the properties of the top 1-1.5 inches. By focusing on the thinnest asphalt sections, the correlation was significantly improved, with an R2 of 0.77.
