ONE-DIMENSIONAL MODEL FOR ANALYSIS OF CRC PAVEMENT GROWTH

The paper describes a 1-dimensional model for predicting the structural response of continuously reinforced concrete pavement due to increasing temperature and alkali-silica reaction (ASR), taking into consideration the slip between concrete and reinforcing bar and friction between concrete and subbase material. The development and use of the model are described. The study showed that ASR may have the potential to cause larger pavement growth than normal annual temperature cycles, depending on the extent of ratcheting, which may contribute to the annual cyclic, thermally induced growth. The effect of lugs on the restraining pavement movement was found to be significant, and the present lug designs, while apparently not providing perfect restraint, appear to cause significant restraining forces. This and other findings are discussed.
