WebBoth asphalt pavements and concrete pavements can develop cracks, though not always for the same reasons. Previously, we looked at some common types of cracks in asphalt pavements, their causes, and how to deal with them. In this edition of the RoadReady newsletter, we’ll do the same for cracking in portland cement concrete (PCC) … WebTwo models were developed to predict the low temperature cracking performance of asphalt pavements. The first model predicts the crack spacing in asphalt pavements exposed to low temperatures based on continuum mechanics and the frictional restraint provided by the aggregate base.
