摘要

Early-age cracking is a major issue in design and construction of concrete pavements. This occurrence depends upon various factors i.e., design features, concrete mixture materials, jointing techniques, and environmental circumstances. This may however occur despite adequate design, construction, and jointing operations are correctly followed. Interactions of the above key factors are assessed using comprehensive analytical methods which are demanding in terms of data input and computational requirements. This research presents a streamlined probabilistic methodology for probabilistic risk assessment of early cracking in airfield concrete pavement design. The method provides a strength-to-stress ratio (SSR) index for identification of critical cracking conditions. A risk chart is presented with reference to the designed SSR value, and the required reliability level of the design process.
