Abstract

This digest summarizes the findings of the research conducted under National Cooperative Highway Research Program (NCHRP) Project 4-20C to identify aggregate tests related to the performance of portland cement concrete (PCC) pavements and to provide guidance on their use for evaluating and selecting aggregates for use in specific pavement applications. The information and guidance presented in this digest pertain to normal-density aggregates. Among the pavement performance parameters identified as having a critical effect on pavement performance and also as being related to aggregate properties are (1) those that occur in all pavement types: alkali-aggregate reactivity, blowups, D-cracking, longitudinal cracking, roughness, spalling, surface friction, and transverse cracking; (2) those that occur only in jointed concrete pavements: corner breaks and transverse joint faulting; and (3) one distress that occurs only in continuously reinforced concrete pavements - punchouts.
