Solved: Chapter 9 Problem 19QP Solution Materials For ...

The main objectives of the asphalt concrete mix design process are as follows: 1) At high temperature and heavy traffic there will be permanent deformation. This is due to the constant load acting on them. The pavement should be able to resist the deformation. 2) Due to repeated application of the wheel load there will be cracking of the pavements.
