Determination of Pavement Layer Stiffness on the Ohio SHRP Test Road using Non-Destructive Testing Techniques

摘要

The purpose of this research project was to determine the relative contribution of each pavement layer toward the overall stiffness of the various test sections on the Ohio SHRP Test Road, as determined from nondestructive tests conducted during the construction of these sections. These tests included Falling Weight Deflectometer (FWD) tests on all pavement layers as they were completed and approved by ODOT, and FWD and Dynaflect tests on the completed sections before they were opened to traffic.
