ABSTRACT:
Systems and methods are disclosed for asphalt mix design by predicting properties associated with a mix of volumetric properties; verifying properties of the mix by digitally collecting data for each gyration from a gyratory compactor; selecting an optimum mix based on the gyration data; determining a percentage of maximum theoretical density; testing properties of the optimum mix with an ignition process; and determining gradation of the optimum mix.
