A full-scale concrete
pavement test section was constructed on State Route 14 in Los
Angeles County. The purpose of this test section was to determine
the fatigue properties of field concrete pavements in California
and the performance of several design options, such as widened
lanes, tied concrete shoulders, and doweled transverse joints.
Accelerated pavement testing of the sections has been completed
on 24 test sections. Analyses of the results will be conducted
to compile a concrete fatigue equation for California rigid pavements.
The effects of temperature and moisture curling on the load response
of concrete pavement will be studied. A performance model will
also be developed to relate load level and repetitions to the
joint deterioration of plain and doweled transverse joints. The
full-scale field results will help improve existing rigid pavement
design procedures and enable better prediction of the service
life of concrete pavements. |
