Abstract: The surface roughness of asphalt concrete is studied according to the maximum aggregate size and to the equation of the aggregate graduation curve, on asphalt concrete plates made in laboratory. The macrotexture increases when the maximum aggregate size increases and it decreases when the aggregate fine contents increases. The asphalt concrete structural behavior is evaluated with rutting, complex modulus and fatigue tests. The study shows stronger mechanical performances of the asphalt concrete when made with larger maximum size aggregate and medium fine aggregate percentage.
