Asphalt concrete, bitumen concrete, or simply asphalt, is the most widely used building material for the development of asphalt roads.
Using asphalt bitumen as a binder, mix designs are formulated in the laboratory, along with fine and coarse aggregates.
It is then tested to produce hot mix asphalt for a wide variety of paving applications.
To meet the demands of today's transportation infrastructure, the performance of asphalt pavements must be continually improved.
Modern asphalt pavements must withstand friction, thermal changes, high load cycles, hydraulic pressures from water and more environmental impacts.
Testing asphalt for properties such as air void content, compaction, bitumen rate determination, filler determination, density, shear strength, hardness, and fatigue resistance ensure durability and longevity for use.
