A NUCLEAR DENSITY GAUGE FOR THIN OVERLAYS OF ASPHALT CONCRETE ---PRE CONFERENCE PROCEEDINGS 3RD IRF MIDDLE EAST REGIONAL MEETING. TOWARDS BETTER ROAD PERFORMANCE, RIYADH, SAUDI ARABIA, 13-18 FEBRUARY 1988. 6 VOLUMES.

The principle of operation of a new thinlayer backscatter density gauge is presented in this paper. Field and laboratory data are used to verify the accuracy of this gauge for directly measuring the density of a thin overlay of material applied over underlying base material. This instrument only requires a good estimate of the overlay thickness to measure the overlay density. The bottom density is algebraically eliminated from the gauge equations, enabling the top density to be calculated using an internal microprocessor. This gauge will be helpful in the road construction industry for measurement of thin overlay density of asphaltic concrete.(a) for the covering abstract of the proceedings see IRRD 817883.
