Technique Concepts of Paving Concrete Designing at the Organic Binding Agents of Elevated Longevity

摘要

The theoretical postulates of designing of modified paving concrete, made of organic bindings by combined modification of asphalt- and tar-concrete have been formed, namely: by modification of binding polymers, integrated with them; doping into the composition of bindings the complex additives, consisting of polymer and active dispersed filling agent; superficial activation with mineral powder by oligomers and polymers. It has been proved experimentally that complex and modified asphalt-concrete and tar-concrete are characterized by elevated values of resistance to water and frost, resistance to thermooxidizing aging; are distinguished for the wide interval of binding and elastic behaviour of paving, uprated of shift resistance and elasticity index.
