Are there any alternate ways to check for asphalt compaction that do not cut holes (asphalt cores) into the roadway?
A Nuclear Density Gauge is frequently used to check for asphalt compaction. This device allows the operator to check the compaction of the asphalt without cutting the pavement. However, in order to use the nuclear density gage, a test strip of asphalt must be constructed. Within this test strip, asphalt cores are taken in order to calibrate the nuclear density gage. Once this is accomplished, asphalt cores are not necessary again at this particular location.
