JUSTIFICATION FOR THE BUILDING MATERIALS REQUIREMENTS IN THE ASPHALT PAVEMENT REPAIR BY THE CEMENT CONCRETE LAYERS

Vyacheslav Savenko Mykola Bykovets

This scientific text examines the main requirements for the composition of cement-concrete mixtures for pavement layers. In particular, it is noted that to obtain high-strength cement concrete, type I and II Portland cement should be used with the content of tricalcium aluminate (C3A) in an amount of no more than 8% by weight. To increase the strength of concrete, it is recommended to add steel or polypropylene fiber. Coarse aggregate of high-strength modified cement concrete can be crushed stone from dense rocks. To obtain high-strength cement concrete, it is also necessary to take into account the requirements for sand, and entraining additives and calculate the composition of concrete in accordance with the methodology for road cement concrete. Ensuring the necessary frost resistance is achieved by selecting the optimal composition of the concrete mixture and using highly active cement. In addition, the text specifies the requirements for the transportation of the concrete mixture, the slump of the cone, the volume of entrained air, and the preservation of concrete properties. The final technological properties of the concrete mixture are evaluated at the design stage
