Abstract
Jointed plain concrete (JPC) pavement slab curling and joint movement have been shown to play a major role in the cracking performance of conventional JPCP pavements and composite HMA/JPC pavements with a renewable surface. These movements have been assessed as part of the SHRP II R21 Composite Pavement project at the University of California Pavement Research Center ATIRC test track. Environmentally induced slab movement both internal and at slab joints was evaluated under several conditions; two slab thicknesses, doweled and undoweled slabs, and overlayed (two thicknesses) and non-overlayed JPC slabs. The aim of this paper is to summarize findings of slab movement research and how this movement is affected by different variables. With the increasing push toward mechanistic design for concrete pavements, the importance of this information becomes ever greater.
