Abstract

Recycling of asphalt mixes can be defined as the restoration of aged mixes. The purpose of this research is to evaluate some old asphaltic surface courses in Damietta governerate for their potential of being recycled. Two types of old asphalt surface in Damietta were sampled and transported to the highway laboratory at Mansoura University. One of the two mixes was a dolomite crushed stone mixed at 6.64 asphalt content and the other was a basalt aggregate mixed at 5.2% asphalt content. Control mixes were also prepared using two virgin aggregates similar to those aggregates under study and designed according to Marshall method. It was found that the two Damietta asphalt mixes had high potential to be hot recycled after the addition of a 12% softener and 30% virgin aggregate. No extra addition of asphalt cement was needed in most cases.
