Asphalt Modifiers - Pavement Interactive
Asphalt Modifiers. Some asphalt cements require modification in order to meet specifications. Asphalt cement modification has been practiced for over 50 years but has received added attention in the past decade or so. The added attention can be attributed to the following factors (Roberts et al., 1996 [1] ): Increased demand on HMA pavements.
