Mix Types - Pavement Interactive

Hot mix asphalt is known by many different names such as hot mix, asphalt concrete (AC or ACP), asphalt, blacktop or bitumen. For clarity, this Guide makes a conscious effort to consistently refer to this material as HMA. HMA is distinguished by its design and production methods (as described in this Guide) and includes traditional dense-graded

Asphalt Balanced Mix Design

Balanced mix design (BMD) for asphalt construction is used to design an optimum asphalt content between problems with rutting on one end and cracking on the other. Tests that are used to determine these parameters are the Hamburg wheel tracking test, the overlay test, the ideal cracking test and shear bond strength testing.

Mix temperature will be dependent on the grade of asphalt used in the mix. The less viscous the asphalt, the lower the temperatures should be. The more viscous the asphalt, the higher the temperature can be. During mix design temperatures are specified for proper mixing and for compaction. These are good targets with which to start a project.
