PUMPING PREDICTION MODEL FOR HIGHWAY CONCRETE PAVEMENTS

Pumping prediction models are essential in the design and economic analysis of rigid pavements. Existing pumping prediction models are reviewed and shown to be insufficient to be used in the prediction of void progression and the economic analysis of rigid pavements. Models were developed to predict the amount of pumped material. The model based on the AASHO road test data and regression models of observed pumping distress is valuable. It can be used in the optimal design of rigid pavements by predicting the effect of different design alternatives on the development of pumping. The amount of pumped material can be correlated with the area of unsupported slab and size of the voids. The pumping prediction model can be incorporated into existing design and economic analysis programs to improve the accuracy of their results.
