Influence of early-age concrete behaviour on concrete pavements performance

摘要

Cracks in joints are the consequence of concrete behaviour in the initial period of use of pavement structures, which can affect structural properties of concrete pavements. Current knowledge on the influence of concrete in the initial period of use of concrete pavement structures is analysed in the paper. The analysis has shown that interaction (in space and time) of the group of joints must be taken into account in the scope of crack behaviour modelling. As a result of this approach, the relationship between joints and crack width can be predicted in order to evaluate their effects on properties of concrete pavements.
