THIN LAYER GAUGES FIND USE IN VIRGINIA

In Virginia, contractors are using a tool for determining the density of asphalt overlay. The instrument's quick test results allow for adjustments in compaction operation. The article describes a thin layer density gauge which will measure the density of a top layer from one to four inches thick without being influenced by underlying layers. In 1987, a new control strip procedure was developed to take advantage of this new technology. Details of the procedure are summarized. In this Virginia program, true end-result specifications are achieved. An advantage for the contractor is in using the gauge to determine the types of rollers needed and in controlling the number of roller passes required to obtain density. It is felt that the instrument is a 'real life' solution to the problem of determining asphalt compaction.
