Mineral That Composed Alphalt Cement

Asphalt Modifiers - Pavement Interactive

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.Traffic volume, loads and tire pressures have increased substantially ...

7 MUST HAVE PROPERTIES OF ASPHALT .

The durability of an asphalt pavement is its ability to resist factors such as changes in the binder (polymerization and oxidation), disintegration of the aggregate, and stripping of the binder films from the aggregate. These factors can be the result of weather, traffic, or a combination of the two. Generally, durability of a mixture can be enhanced by three methods. They are:
