Thermal resistance of concrete airfield pavements

Abstract

Abstract Concrete airfield pavements can frequently suffer from initially small and relatively shallow delamination of the subsurface concrete layer. It may be due to natural and forced temperature impact on the pavement. As a result of these impacts, thermal stresses and other phenomena are formed in the concrete slab. The significant phenomena are those related to the movement of water vapour in the slab cross-section and the associated processes leading to defects of the concrete structure. They are due to the complex interaction of various phenomena: thermal, humidity and strength that were considered damage stimulants.
