Impact of utilization recycled concrete as a partial substitution of the coarse aggregate of hot asphalt mixture surface

Recycled aggregate pavement in bituminous can be repercussion to mitigation the exhaustion of rudimentary and asphalt, orientation alleviation quantities tailings organized into garbage dumps. This research aimed investigate performance Hot Mix Asphalt (HMA) surface with recycled concrete (RCA) as a replacement natural aggregates (NA) four substitution rates (0, 20, 40, 60) % from coarse aggregate. Four HMA were designed by using conventional Marshall method density, air void, flow stability. The results indicated properties mixes RCA have weaker impact on asphalt mixture. Generally, articulate that employment lead reduce density stability while procure increase void percentage values greater than its value
