Abstract

MIXTURE / FOR DEVICE ROADS COVERINGS, including tall peck, limestone mineral powder, granite sifting and modifying additive, characterized in that, in order to improve strength and water resistance, it contains as a modifying additive bottom residues of the production of regenerated caprolactam in the following ratio components, wt.%: Tall pitch 7.5–8.1 Lime mineral powder 7–10 Vat residues from the production of Regene (Preserved caprolactam 0, 5–0.9 Granite screenings Else

Description

The invention relates to road construction and can be used in the paving of roads and airfields. It is known the use of tall oil pitch as an asphalt concrete mixture lj. The disadvantage of tall pitch mixtures is low shear resistance, which is a reason for reducing the durability of coatings. The closest to the technical essence and the achieved result to the proposed is a mixture of 2j for the installation of coatings and road bases, including, wt.%: Tall pitch 7-8 Lime mineral powder 8-10 Polyethylene 0.05-0.1 Granite screening Else However, this mixture is characterized by insufficient strength and an increase in water expansion. The purpose of the invention is to increase the strength and water resistance of the resulting coating. The goal is achieved by the fact that the mixture for paving, including tall peck, limestone mineral powder, granite sifting and modifying additive, as a modifying additive contains bottom residues from the production of regenerated capro-35 lactam in the following ratio, wt.%: 7 , 5-8,1 Tallovy Peck Limestone

The bottoms residue of the production of non-irred caprolactam is introduced into tall pitch, heated to 100 ° C and stirred until homogeneous. Asphalt mix is prepared using conventional technology for hot rolled concrete. Prepare three mixtures of the ingredients presented in Table. 1. The test results for these essay are given in table. 2.
