20 Years’ Performance of LTPP SPS-2 Sections in Wisconsin: Transverse Joints

As part of the Long Term Pavement Performance SPS-2 (Strategic Study of Structural Factors for Rigid Pavements) Program, a total of 19 sections of jointed concrete pavements were constructed on STH 29 in Wisconsin in 1997. Variables included in the program were slab thickness, slab width, concrete strength, and base type. These sections have been continuously monitored since then. This paper focused on the 20-year performance of transverse joints. The performance was correlated with design variables and materials testing results. It was found that the main contributing factors to joint spalling are (in descending order of significance) air content, slump, slab thickness, lane width, load transfer efficiency, dowel bar diameter, and PCC flexural strength. The risk of joint spalling could be minimized by reducing air content, increasing slab thickness, widening slab, and increasing load transfer efficiency.
