Determination of Importance of Various Parameters on Performance of Rigid Pavement Joints

摘要

The objective of the present study was to evaluate the effects of various parameters on an experimental concrete pavement in Ross County, Ohio. Variables included in the pavement were (1) joint spacing, (2) sub-base stabilization, (3) coating of dowel bars, (4) configuration of the saw cut and (5) the use of skewed joints. Both long term and short term horizontal movements caused by temperature and vertical movement of slab ends under known axle loads were measured. A record of cracking and spalling of the pavement is also included. A statistical analysis of both long and short term movements was conducted and recommendations for joint design are included.
