Abstract


The quality of asphalt mixture is strongly influenced by its row materials. This study was carried out in order to assess the suitability of material gradation which was ready in market. The gradation design of the porous asphalt with maximum compression method\ (MCM), applies local material : aggregate A(9 to 12,7 mm); aggregate B (4,75 to 9 mm); aggregate C ( 2,8 to 4,75mm) aggregate D(0,5 to 2,8 mm) and filler. The research resulted that the gradation called “LJR-Semar” with proportion of aggregate (%) A: 16,32; B: 16,32; C: 48,96 and D:14,40 and Filler: 4. Validation of mixture with Marshall Test, obtained 453,83 kg of mixture stability with 4% of optimum asphalt content, 30,30% of mixture porosity; 2,67 mm of flow; 2007,50 kPa of unconfined compressive strength and 58,71 % of Cantabrian test.
