ABSTRACT:
An apparatus and a method optimizes a job mix formulation (JMF) for hot mix asphaltic concrete. The apparatus receives JMF data input, including hand-entered data, hand-drawn data, or computer optimized data. The apparatus then generates a voids in the mineral aggregate (VMA) value. Next, it prompts the user to select a design methodology, including a Marshall mix methodology, a Hveem mix methodology, a Strategic Highway Research Program mix methodology, or a user definable mix methodology. Once the appropriate methodology has been selected, the apparatus applies a number of computations which use the VMA value. The apparatus also generates an aggregate composition for the hot mix asphaltic composition satisfying the job mix formulation based on the JMF data input and the selected design methodology.
