•Binder content

Quantitative determination of the asphalt binder content of HMA mixtures and pavement samples is necessary for many reasons, including: quality control, specification acceptance, and mixture evaluation studies. HMA that has too much asphalt binder can experience problems such as bleeding, lowered skid resistance, and lowered resistance to permanent deformation (rutting and shoving.

•% Air voids

Asphalt consists of four main materials: bitumen, aggregate, fillers (fine particles) and air. Asphalt without sufficient air entrapped in the layer will deform under traffic and result in a rutted and rough surface.

•Asphat Coring

Asphalt core cutting test to determine the thickness of the asphalt layer, compaction and other properties.

•Asphalt Softening Point Test: all asphalt is created the same, engineers need to predict how well an asphalt mixture will perform in addition to the maximum load it can support

The determination of softening point helps to know the temperature up to which a bituminous binder should be heated for various road use applications.
