Heavy Weight Deflectometer (HWD) Tests
HWD tests were performed by the FAA on the completed surfaces of the P-154 sub-base, the P-209 base, and the P-401 asphalt pavement. Tests were performed on center line, two per each of the four pavement sections. For the P-401 asphalt, additional tests were performed on a 10 foot grid over the entire pavement. These latter tests comprised a check on uniformity. Tests were also performed over the MDD locations both before and after MDD installation. As in the laboratory Tests, HWD tests provided additional information about the pavement structure and were not related to the acceptance tests.
