How to Design Bituminous Mixes: Steps and Methods [with mix ...

The aggregates and bitumen are separately heated to a temperature of 154 to 160°C and 175 to 190°C, respectively. The quantity of bitumen by weight of the mix is measured and poured into the heated aggregate. The mix is uniformly blended and poured into a standard cylindrical mould (102 mm diameter and 64 mm depth) heated to 93-149°C.

Marshall Mix Design

The mix design (wetmix) determines the optimum bitumen content. This is preceded by the dry mix design discussed in the previous chapter. There are many methods available for mix design which vary in the size of the test specimen, compaction, and other test specifications. Marshall method of mix design is the most popular one and is discussed ...

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.
