Original design by Simple Themes. When designing asphalt pavements there are three main elements that must be consid- ered. 3 select and specify the most appropriate mix design method and criteria for the application.

2 To achieve the desired minimum strength in the hardened stage. The structural HMA layers are usually referred to as surface intermediate and base courses depending on their location in the pavement structure. This is the primary overview course on Asphalt Concrete Materials Mix Design in the training certificate program offered by the City and County Pavement Improvement Center CCPIC in partnership with TechTransfer.

It is important that a Job Mix Formula for the paving mixture be established for and approved by the engineer. MARSHALL MIX DESIGN METHOD FOR ASPHALTIC CONCRETE An Arizona Method 1. Voids in the mineral aggregate VMA The volume of the intergranular void space between the aggregate particles of a compacted paving mixture that includes the air voids V.
