FIELD: chemistry. ^ SUBSTANCE: invention pertains to binding material for road surfaces. It can be used in road and airfield construction, as well as in roofing, waterproofing and tight seams. The proposed binding material for road surfaces contains bitumen, caoutchouc and a solvent-plasticizer. It is unique in that, the solvent-plasticizer used is rape oil or a mixture of distilled tall oil and pentaerythritol, taken with mass ratio of 7:1. The caoutchouc used is a copolymer of ethylene with vinyl acetate, with components in the following mass percentages: 95.00 - 99.50% bitumen; 0.41-4.10% solvent-plasticizer; 0.09-0.90% copolymer of ethylene with vinyl acetate. ^ EFFECT: the binding material can be used in road or airfield construction, as well as in roofing, waterproofing and tight seams. ^ 2 tbl |
