Applications for Specialized Asphalt
Design
Asphalt Concrete for
Race Tracks
Surface must be smooth but remain durable and resist fatigue cracking
Aggregate must provide good tire friction without excessive wear to tires
Binder must resist becoming soft at high temperatures
Objectives
Designed for high shear stresses and high temperatures
Polymer Modified Binder
Coarse Rock
Slag
