Abstract.
Micro vascular size is smaller, and also includes material transfer, exchange and chemical composition and the role of electric charge.

It is crucial to have a sufficient understanding of cracking mechanism
in order to produce a sound and safe material and structural design of asphalt pavements.
Introduction Asphalt concrete is the most commonly used material in pavement construction today because of its favorable properties such as elasticity, stability, durability, and water resistance.
