Effect of Crumb Rubber and Warm Mix Additives on Asphalt
Asphalt-rubber mixtures have been shown to have useful properties with respect to distresses observed in asphalt concrete pavements. The most notable change in properties is a large increase in viscosity and improved low-temperature cracking resistance. Warm mix additives can lower production and compaction temperatures.

Benefits of Recycling Waste Tires Rubber Asphalt Paving
the crumb rubber to the asphalt mixture distinguishes the processes between "wet" and "dry". In the dry process, crumb rubber is added to the asphalt cement mixture to replace some of the aggregate in the mixture. The wet process adds the crumb rubber to the asphalt cement to modify the physical and chemical properties of the asphalt cement.
