SU816998A1 - Binder for road mixtures - Google Patents

Description

one

The invention relates to construction materials, in particular to road substances for road mixes.

It is well known for road mixtures, including coal tar and ablation dust from cement kilns iL

The closest in technical essence and the achieved result to the proposed one is stinging for road mixes, including coal tar and qunel coal in the amount of 5-30% by weight of the anthracene fraction E2.

The disadvantage of these compositions is their reduced viscosity and adhesion. to stone materials.

The purpose of the invention is to increase viscosity and adhesion to stone materials.

This goal is achieved by the fact that, as a road mixture, including coal tar and carbon-containing compound, the latter contains calcium salts of bottom fatty acids in the following ratio of components, wt.%;

Coal tar 70-95

Calcium salts bottoms

fatty acids 5-30

Cooking is prepared by neutralizing vat fatty acids with active calcium oxide and adding the resulting salts to the coal tar.

with heating and stirring or by adding to the resin cubic acid of cubic acids, followed by neutralization of these acids with calcium oxide, in the resin medium at 11 ~ 200 ° C, preferably 110-140 ° C. The calculation of the required amount of calcium oxide is based on the acid value.

In tab. 1 shows the compositions of the proposed mixtures.

The test results of these compositions are given in table. 2

The gusher has increased viscosity and adhesion to stone materials.

On the described in the shearer, a fine grain deggeasphalt concrete of the following composition, wt.%:

It is recommended to use the proposed for cold, warm and hot road mixtures.
