Asphalt, also known as bituminous conglomerate, is a fundamental material of road construction. It’s primarily composed of aggregates and binder with an infinite variation of mixtures. The binder of the asphalt is called bitumen. As traffic conditions increase, there’s an ever-growing need for higher performance levels of the asphalt present in today’s roads.
Asphalt testing is important to ensure that asphalt looks like the constituent mix and has all the necessary performance characteristics. It’s also increasingly important to monitor asphalt for voids percentage, compaction levels, and characteristics such as the stiffness modulus and fatigue resistance in relation to the temperature, together with frequency of load or strain application.
Modern asphalt pavements must resist rutting, thermal variations, high load cycles, hydraulic pressures from water, and more. Creating a mix with long pavement life and low maintenance costs begins with extensive testing in the lab. Aggregates, binder types, and additives are evaluated separately before finding the correct proportions for blending. Once a suitable mix design has been established, quality control and quality assurance testing guarantees installation of a quality pavement.
Gilson's complete line of asphalt testing equipment accounts for all of this and more with an extensive selection of asphalt mix design testing, asphalt binder testing, and pavement quality testing equipment for both Marshall and Superpave mixes.
