In this work, Dense and Gap graded Asphalt Concrete samples were compacted in thelaboratory using two modes, the first one was the traditional Marshall method of hammercompaction; Cylindrical specimens were constructed using three different Asphaltpercentages; While the second mode was the TRRL roller wheel compaction, slab samples of(30×30×7) cm were constructed using the same Asphalt percentages, core specimens wereobtained from the slabs. All of the Asphalt Concrete specimens were subjected to Marshallproperties determination, indirect tensile stress test, Hveem stability and cohesion tests. Acomparative analysis of testing results was conducted. It was concluded that Dense gradedAsphalt Concrete shows superior quality whencompared to Gap graded one when roller wheel compaction was adopted. Gap graded AsphaltConcrete shows higher quality when Marshall Hammer compaction was adopted.
