A study of cores from both the concrete and subbase of the cracked pavement, along with an examination of the in-place subgrade and subbase, suggested that there was no structural damage to the pavement except for the cracking. The situation was aggravated by the poor lateral drainage, which was being corrected by the excavation of shoulder material and backfilling with an open-graded aggregate. Since it was thought that this action would stabilize the condition of the pavement, no corrective action other than sealing of the longitudinal cracks was recommended.

Although much progress has been made in reducing concrete’s propensity to crack, the goal remains elusive. A novel approach to this problem is the f...
