註釋The New York State Department of Transportation has continued its research on density of asphalt concrete surface courses, an earlier phase of which was described in Research Report 65-6. Test sections on new pavements in 11 locations throughout the State were cored when constructed in 1962 and each subsequent year through 1967. Some 1200 cores were processed for bulk specific gravity, asphalt content, voids, and gradation analysis; relative densities were based on 200 Marshall specimens.
