Asphalt Road Surfacing Materials Selection Guide: Types

There are six materials for preserving an original asphalt road surface to aid in the longevity and condition of the surface. The six are chip seal, fog seal, microsurfacing, spray patch, dust control, and crack filling. Chip seal is a layer of aggregate that is covered with a spray asphalt binder and is designed to protect and prolong pavement.

Asphalt Durability - Pavement Interactive

Asphalt durability is a measure of how asphalt binder physical properties change with age (sometimes called age hardening). In general, as an asphalt binder ages, its viscosity increases and it becomes more stiff and brittle. Age hardening is a result of a number of factors, the principal ones being (Vallerga, Monismith and Grahthem, 1957 [1
