Asphalt testing is an important part of ensuring the quality of the material. By understanding the purpose and process of each test, it is possible to ensure that the asphalt used in construction is of the highest quality. Asphalt, also known as bitumen, is a sticky, black, and highly viscous liquid or semi-solid form of petroleum.

Additionally, only the PATTI test is a promising test for evaluating adhesive properties of asphalt binders. All three other tests (the pull-off test, DME, and surface energy test) were not successful in this study for evaluating asphalt binder adhesion property. Obviously, these laboratory findings need further field validation.
