Abstract EN
In this study, a small-scaled accelerated loading test based on similarity theory and Accelerated Pavement Analyzer was developed to evaluate dowel bars with different materials and cross-sections.
Jointed concrete specimen consisting of one dowel was designed as scaled model for the test, and each specimen was subjected to 864 thousand loading cycles.
Deflections between jointed slabs were measured with dial indicators, and strains of the dowel bars were monitored with strain gauges.
The load transfer efficiency, differential deflection, and dowel-concrete bearing stress for each case were calculated from these measurements.
The test results indicated that the effect of the dowel modulus on load transfer efficiency can be characterized based on the similarity model test developed in the study.
Moreover, round steel dowel was found to have similar performance to larger FRP dowel, and elliptical dowel can be preferentially considered in practice.
