Top-down cracking of rigid pavements constructed with fast setting hydraulic cement concrete

Abstract

Jointed plain concrete pavement (JPCP) test sections were constructed using fast setting hydrualic cement concrete (FSHCC) as part of the California accelerated pavement testing program (CAL/APT). Many of the longer slabs cracked under environmental influences before any traffic load was applied to them. Data from field instrumentation was recorded and analyzed along with laboratory test data to determine the cause of the cracking.
