Abstract

The invention relates to road building materials and can be used to prepare pavement mixtures. The purpose of the invention is to increase the depth of penetration of the needle and extensibility to a person at 0 ° C, as well as to increase the compressive strength of concrete based on it at 50 ° C. The method of preparing the to-be is to mix tall pitch with sulfur in a ratio of (4.0-5.0): 1 and incubate at 150-160 ° C for 15-20 minutes, followed by stirring the mixture with heavy oil or oil tar at 140-150 ° C for 20-25 minutes. The needle penetration depth at 0 ° C (26-36) xO, 01 mm, stretchability at 0 ° C 12-15 cm. Compressive strength at concrete at 50 ° C 2.4-3.0 MPa . 2 tab.

WITH

The invention relates to road building materials and can be used to prepare mixtures of pavements.

The purpose of the invention is to increase the depth of penetration of the needle and extensibility into a person at 0 ° C, as well as increase the compressive strength of concrete based on it at 50 ° C.

In-wall pitch, heated to 120-125PC, the calculated amount of sulfur is added in portions with constant stirring. After adjusting the temperature of these components to 150-160 ° C and incubating for 15-20 minutes, right-hand tar or heavy oil, preheated to 140-150 ° C, is added. The resulting stirrer is additionally thermostatic with constant stirring for 20-25 minutes.

Tall pitch is a waste from the pulp and paper industry, which contains non-volatile resins and resin and fatty acids, which are surfactants.

Technical sulfur is a dark amorphous mass obtained by autoclaving its smelting from sulfur-containing ore.

Petroleum tar (bitumen raw material TU 38 101582-75) is a residual product of oil refining (distillation of light benzene and oil fractions).

Heavy oil is a viscous, tar-like mass. Due to the high content of sulfur compounds and low content of light (kerosene) fractions, it is not suitable for processing in the oil industry.
