Improving asphalt density


Troxler Nuclear Density Gauge device

Nuclear Density Gauge vastly improves density measurements.

Innovative new asphalt compaction control technology is set to pave the way for vast improvements in determining density in bituminous overlays in Tasmania.

The first of its type in Tasmania, the new Troxler 4640B Nuclear Density Gauge acquired by Roadways, is expected to significantly reduce procedures and testing time as it facilitates more immediate results for improved quality control and management.

Widely recognised as the most efficient method for analysing density in thin lift asphalt, it will greatly reduce the number of core holes required to accurately determine lot densities of asphalt. Core samples will only be required initially to determine offset values and later to confirm them. Improved capability also extends to accurate and immediate readings within one minute and can store up to 750 readings by location and project number. Density values will also be determined within 24 hours of asphalt being laid, and immediately after test is completed on site.

The newly introduced Troxler technology is specifically made for asphalt lifts between 25 and 100mm compared to conventional gauges that are only able to measure the density of lifts greater than 50mm using Australian Standards testing methods.

Roadways is the only local NATA accredited operator for nuclear density testing of asphalt and can issue NATA endorsed reports enabling significant improvements and efficiencies in quality testing and project management for bituminous surfacing.
