RATIONALE FOR ASPHALT CONCRETE MAKING WITH ASPHALT MILLINGS AND ADDITIVES ADDING

Abstract

The article is devoted effective methods development for introducing asphalt millings into a new asphalt concrete mixture also with using anti-aging additives. The crushed old asphalt concrete formed during the road surfaces repair, subject to appropriate technology, can be reused efficiently. The authors investigate the characteristics and determine the resulting mixtures cost at using various percentages of recycled material. In addition to the main research it was extra tasks to study the fiber effect on the strength of asphalt mixtures. The possibility and expediency of using asphalt millings in asphalt concrete mixtures have been established. Basing on theoretical and experimental studies accordance in terms of physical and mechanical properties with the GOSTs requirements was found. Using road repair works waste as a full-fledged asphalt concrete component allows to solve environmental problems, reduce a new mixture production cost, and save energy resources.
