Modern Ideas About Cold Asphalt Concrete Mixtures with a Regulated Period of Structure formation
Abstract: This paper presents data characterizing cold asphalt concrete road mixtures with adjustable structure formation periods. Cold asphalt concrete mixes are a promising material in road construction. They have high plasticity and resistance to low-temperature types of deformations, which ensures their reliable operation at subzero temperatures. Due to their properties, cold asphalt concrete mixtures can be used for repair work at any time of the year, in particular in winter, which makes them an effective material for road construction and repair in difficult climatic conditions. To change the properties of the asphalt concrete mixture, as well as to regulate the processes of structure formation, various types of additives are introduced into the composition of cold asphalt concrete mixtures. Sealing additives increase the density and strength of the material. Regulators of the rate of structure formation accelerate or slow down the process of structure formation. Structuring additives ensure that the asphalt concrete mixture takes a certain shape after being laid and compacted into road clothes. Active mineral additives increase its wear resistance, and fibrous additives improve its resistance to cracking.
Keywords: cold asphalt concrete mix, modifier, structure, durability, viscosity, density.
