(54) BINDING FOR STRENGTHENING SOIL

I

The invention relates to the construction and technical reclamation of soils and can be used when laying pipelines.

It is known to contain, including the bottoms of the distillation of crude benzene and heavy high resin oil 1.

The closest to the proposed technical essence and the achieved result is a stranger 2, which includes the residue of thermal cracking of tar and neogrin at the following ratio of components, May. /about:

Thermal residue

cracking tar 25-75

Niogrin25-75

A disadvantage of the known people in the community is the low strength of the fortified soil.

The purpose of the invention is to increase the strength of the reinforced soil.

This goal is achieved by the fact that, as a petroleum-based agent, the latter contains the bottom residue of the distillation of the cracked oil residue and the low-clotting oil fraction 180-

350 ° C with the following ratio of components, May. %:

VAT residue of the distillation of cracked NPa residue 40-75

Low cure oil for fractions of 180-350 ° C25-60 The bottoms residue of the cracked oil residue is a black viscous product, thickens during storage, is insoluble in water, and has the following properties:
