A Case Study: Early Cracking of Unreinforced Concrete Pavement

Report No: 73-R20

Published in 1973

About the report:

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.
