High levels of performance are required of today’s asphalt. The resistance of bituminous road paving depends on two characteristics – internal friction, dependent of the blend and quality of the aggregates; and cohesion, which is dictated by the bitumen content. Asphalt testing encompasses testing for both consistency and performance characteristics of the mix.

Geo-Con offers a range of apparatus for the testing of asphalt and bitumen that meets the latest national and international standards.
