A methodology was developed for estimating the remaining life of a nonoverlaid continuously reinforced concrete pavement. The models presented use several key predictors: the early-age crack distribution pattern in the concrete caused by volumetric changes, the coarse aggregate type used, and the presence or absence of a swelling subgrade that will accelerate the rate of failure development in later life due to dynamic loadings. Considering these factors, the models can accurately estimate the additional 18-kip equivalent single axle loads (ESALs) that will take the pavement from its current condition in terms of failures per mile (FPM) to a user-defined "failure threshold", such as 10 or 15 FPM. Using traffic models developed in another study, the number of additional ESALs to failure can be translated into time to failure for planning purposes. The overall objective of the analysis is to determine the optimum time to overlay--before failure and preferably before the onset of irreparable damage to the pavement.
