Deviation Detection and Comparison Analysis of the Joints of Cement Pavements

Abstract

Joints are weak links in the structure of cement pavements, and heavy traffic sections must be set up to maintain the transmission capacity of the board and to ensure the long-term use of pavements. However, with the advancement of force transferring rod construction technology, concrete with ratio and construction control of the influence of the force transmission rod actual spatial location and design of the location will inevitably produce some deviations. Given that such deviation will rapidly reduce the transfer capability of the board, the deviation of the transmission rod must be controlled in the construction process. However, basic data on the transmission rod are lacking. To this end, this paper conducts an experiment in the Beihei Expressway in Heilongjiang Province using MITSCAN2, and the test results are compared with the actual test data of two highways in the US and Canada. Some technical measures for improving the deviation of the transmission rod in the construction process are then proposed based on the detection and analysis results.
