MODELLING OF TRANSIENT PERFORMANCE OF CRACKING INDEX OF CONCRETE PAVEMENT SLAB

Transient performance of the cracking damage of concrete pavement slab was modelled by means of the statistical analysis of the results of the condition survey of pavement surfaces. In the modelling, a double exponential function was applied to the formation of the cumulative distribution function of the annual increment of the cracking index. The validity of the model was verified statistically by the goodness-of-fit test between the surveyed cumulative frequency and the calculated distribution by the model. Reliability of concrete pavement against the cracking damage can be evaluated by this model.
