Description

I

This invention relates to road building materials. It can be used when constructing pavements and waterproofing layers.

. In road construction, fast and slow disintegrating emulsions are used that contain an organic sticking oil, for example, bitumen and an aqueous solution of an eulgator 1. about

The closest in composition of the known emulsions is an emulsion comprising bitumen, an emulsifier, hydrofluoric acid and water 2.

The main disadvantage of the known emulsions is that they can be used only for a certain type of work. The duration of the formation of coatings based on these emulsions varies from 1 to 30 days and depends on weather conditions.

The purpose of the invention is to control the rate of disintegration of the emulsion and to improve

The process of forming a mixture of stone material with emulsion.

The goal is achieved by the fact that a road emulsion comprising black permeate, hydrofluoric acid, emulsifier and water contains. as a black petroleum tar, as an emulsifier, urine & wine-formaldehyde resin and additionally includes polyethylsiloxane in the following ratio of components, wt. %:

Oil oil tar 40.0-60.0

 Fluorosilicic acid 0.1–3.2 Polyethylsiloxane is used as a hydrophobicizing additive to oil tar, while fluorofluoric acid in an emulsion is used in the form of a timer of a mixture of stone material with emulsion. ..; The proposed emulsion is prepared in mixers, supplying the pins with a rotating paste. During emulsion detoxification, an oil tar heated to 60-80 ° C is loaded into the mixer, then polyethylsiloxane is fed in small portions or a continuous stream with continuous operation of the blades. The oil of the tar oil with polyethylsiloxane is pumped for a minute until the odnor mass is received, 15 The resulting oil sludge with polyethylsiloxane is introduced into urine and formaldehyde resin with a small amount in 2-3 steps or in a continuous stream with continuous operation of the blades; stirring is continued until a dark brown uniform mass is obtained. At the end of the mixing, the highly concentrated solution obtained was diluted with water previously combined with a formation time regulator.
