Development of safe construction temperature ranges to avoid blow-ups in Ultra-Thin Concrete Pavements

Abstract

After the construction of an ultra-thin concrete pavement, ambient temperatures may induce an axial force within the pavement due to thermal expansion that can lead to the formation of a blow-up failure. By analysing the mechanism of a blow-up, temperature differentiates at which a blow-up failure in ultra-thin concrete pavements may occur were identified. Safe construction temperature range graphs were produced for different ultra-thin concrete pavements to serve as a guideline that would potentially limit the occurrence of blow-ups.
