- Abstract
- This paper compares the load transfer efficiency between precast concrete pavement specimen and typical concrete pavement
specimen by means of laboratory and field tests. An experimental method was developed to evaluate the load transfer efficiency
of the dowel bars buried in the concrete pocket and grouted with cement mortar. The test results showed that the load transfer
efficiency of the specimen for the dowel bars repaired with grout was equivalent to that of the control specimen. In addition,
a series of FWD field tests were conducted on the precast pavement to evaluate the joint stiffness. The field test results revealed
that the central deflection of the precast slab slightly increased but the load transfer efficiencies at the joints were almost the
same as those in the typical concrete pavement slab.
