Asphalt FAQ - Plantmix Asphalt Industry of Kentucky

Asphalt is the most economical paving material in the world. Pavements can be evaluated on both "initial cost" and "life cycle cost." In the vast majority of circumstances, asphalt pavement will provide the most economical solution in terms of initial cost and also when evaluated over a 30 to 40 year period.

Warm mix: the push is on| Concrete Construction Magazine

May 19, 2006 · Warm mix asphalt technologies typically use an additive to the mix or to the binder to create the asphalt mixture at a temperature range of 250º to 275º F. In contrast, hot mix asphalt runs from 275º to 325º F. Because warm mix is made at lower temperatures, the heating and mixing process reduces gaseous emissions and odors, compared to hot
