Reasons for Cracking of the Cement Concrete Pavements from Strong and Frost-Resistant Concrete

World practice (USA, Germany) has already noted the cases of continuous cracking of the surface layers of cement concrete pavements. Continuous cracking becomes evident several years later after completing construction and results, as a rule, in deterioration of the performance characteristics of the pavements. The paper shows the results of investigation of the pavement concrete on which 3 years later after completing construction there appeared surface cracks up to 2 mm wide and several mm deep with different spacing between them. The paper presents the design nomogram for explaining the reasons of pavement cracking and the recommendations for preventing such cases.
