Called asphaltic concrete, bituminous concrete or just asphalt, it is the most widely used construction material for development of paved roads. Using asphalt bitumen as a binder, along with fine and coarse aggregates, mix designs are formulated in the lab. Then carefully tested to produce hot-mix asphalt for a wide variety of paving applications. Performance of asphalt pavements must continuously improve to meet the demands of today’s transportation infrastructure.
Modern asphalt pavements must resist rutting, thermal variations, high load cycles, hydraulic pressures from water, and more. Testing asphalt for characteristics such as air void content, density, shear strength, stiffness and fatigue resistance provides assurances that this construction material is up to the task.
Producing pavement mixes with long 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.
