Flexible Pavement Design (Full-Depth Asphalt and Rubblization
In Illinois, hot-mix asphalt overlaid concrete pavements typically exhibit reflective cracking of joints and cracks from the pavement below, resulting Problem: Perpetual asphalt concrete (AC) and long-lastingPortland cement concrete (PCC) pavements are relativelynew to the pavement community.
PDF Investigation of Rutting in Asphalt Concrete Pavements
Pavement cores were collected from rutting asphalt concrete pavements less than 2 years after last overlay. Tests were performed in an attempt to determine the cause(s) of rutting. Findings revealed commqn causes such as excessive asphalt, fine-grained aggregate and natural, rounded aggregate
