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 …

By presenting a method for estimating the remaining life of continuously reinforced concrete
pavement (CRCP), this report provides a means for determining the optimum time to overlay
such pavements. Previously, determinations of remaining pavement life relied solely on
engineering judgment. And while subjective experience can often lead to satisfactory
solutions, a standardized procedure-such as that provided by this study-will allow more
objective assessments and, hence, more uniform results. To develop a new procedure for …
