Influence of aggregate properties on effectiveness of interlock joints in concrete pavements

Nowlen, W.J.

Laboratory results from repetitive loads made to evaluate aggregate interlock as load transfer mechanism at pavement joints; tests were made to study influence of aggregate size, hardness, and age at time of joint cracking, on load transfer effectiveness; results indicated that large aggregates were beneficial in maintaining load transfer, especially for larger joint openings; early cracking resulted in more aggregate pullouts than later cracking, which resulted in more aggregate fracture; aggregate pullouts provided better load transfer.
