Highway Pavements And Materials Lab 
This test involves the preparation of asphaltic concrete specimens having a given aggregate gradation and different asphalt cement contents . Then the specimens will be tested by the "Marshall Method " , and evaluated relative to void / density characterstics to arrive at a design value for asphalt cement content .Finally , the interpolated physical and mechanical properties of the compacted asphaltic concrete will then be compared with specifications for paving mixtures and a job mix formula will be calculated .
Standard : ASTM D1559 – 76
