Abstract

The project presents the approximate method to specify temperature changes which may cause and intensify the pavement slabs destruction. Criteria of thermal concrete resistance in case of pavement structure were specified. Defining the acoustics performance, the degree of changes occurred in surface layer and changes in basic mechanical parameters as criteria of pavement thermal condition were suggested. The process of cement concrete damage in case of pavement structure, as a result of combined temperature changes and vehicle traffic was also discussed. Criteria of fragile damage of concrete slab and allowable stress of concrete layer in case of pavement structure were described. Types of heat flow within the pavement were discussed and associated with the occurred damages. The destruction process of concrete pavements under the influence of temperature was presented. The publication contains the proposal of reducing the effects of the aforementioned factors on the range of the occurred stress. The analysis does not include the complex issue of thermal stress within concrete pavement, caused by hot exhaust gas stream.
