Description

(54) MIXTURE FOR ROAD COVER

The invention relates to road building materials and can be used to pave road bridges as well as pedestrian walkways. A known mixture for road coating device tlj. incl., wt. Bitumen 6.0-9, O Surface-active substance 0.01-0.05 Crushed stone from porous glass tiles of tallic material 25-50 Stone mater ialOstalnaya The closest to the proposed technical essence and the achieved result is a mixture for pavement device 12, including organic in the dead - bitumen pulverized waste polystyrene, modifying additive - 1%, solution of copper sulphate and mineral material in the following ratio of components, May. %: Bitumen4-7 Dusty waste polystyrene1, 0-8.0 1% solution of copper and copper1.0-4, O Mineral material Remaining The disadvantage of these mixtures is low frost resistance and decorative coatings. The purpose of the invention is to protect the frost resistance and decorativeness of the coating. The goal is achieved by the fact that the mixture for a pavement device, including organic sticking, pulverized polystyrene waste, modifying additive and mineral material, contains tall tack as organic sticking agent, and polyethylene wax and additionally grinding abrasive wheels as a modifying additive. fractions less than 5 mm in the following ratio of components, wt.%: 7.2–9.0 Tall pitch Polysti 2 dust-like, O-5.0 rolls Polyethylene 0.8-1.0 wax Abrasive wheels crushing waste 10.0-25.0 fractions less than 5 mm Mineral Remaining material In this case, the mixture for arranging the floor coating contains oil-soluble P WJI V t ™ - - "- - d- -paints in an amount of 2.0-5% by weight Tulsi pitch is supplied with a softening temperature according to GOST 11506 –73, 39–43 ° C, polyethylene wax — with a dropping temperature of 8–10 ° C. The mixture was prepared in a manner. Tall Peck and Polyethylene Wax (Heated to 11 ° –130 ° C and mixed

The iioro of the material heated to 130 — with a cold waste from the grinding of abrasives — after which dust-like waste polystyrene is introduced. The whole mixture is stirred for 2 to 3 minutes. Prepare three intermixed components, the groups of which are listed in Table. 1. After having tested these compositions, the results are obtained, which are listed in Table. 2. Mixtures with dyes, the compositions of which are listed in Table 2, are also prepared. 3. The properties of these compounds are given in f-fL table. 4. As can be seen from the table. 4, the introduction of dyes does not affect the properties of the resulting coating, but contributes to the coating of various colors. The coating of the composition proposed has frost resistance and is decorative in comparison with the known ones that are black or gray. Table 1
