| Abstract | ||
| In this work, Dense and Gap graded Asphalt Concrete samples were compacted in the laboratory using two modes, the first one was the traditional Marshall method of hammer compaction; Cylindrical specimens were constructed using three different Asphalt percentages; 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 were obtained from the slabs. All of the Asphalt Concrete specimens were subjected to Marshall properties determination, indirect tensile stress test, Hveem stability and cohesion tests. A comparative analysis of testing results was conducted. It was concluded that Dense graded Asphalt Concrete shows superior quality when compared to Gap graded one when roller wheel compaction was adopted. Gap graded Asphalt Concrete shows higher quality when Marshall Hammer compaction was adopted. | ||
