Description

eleven

The invention relates to road building materials and can be used in the construction of road and airfield pavements.

The aim of the invention is to reduce water saturation and accelerate the formation of a coating.

Water is heated in tall pitch to 60 ° C, then Na-alcohol is added at ambient temperature and stirred for 25-30 minutes. The obtained substance is mixed with mineral materials having natural moisture at.

Put the mixture at ambient temperature not lower than +5 C.

Tall pitch - a by-product of the sulphate-pulp industry, has a softening temperature of 25-45 ° C, an acid number of 30-50 mg / g, a saponification number of 80-100 mg / g.

Dry ash of shale has the following chemical composition, wt.%: SiO, 2A, 60; 4.40J 6.75; CaO 47.11; MgO 4.98; SO- 6.75; ppt rest.

Dust is a waste of crushing of rocks, while it has grains smaller than 5.0, 2.5, 1.25, 0.63, 0.315, 0.14 0.071 mm, contains 91-96, 75-85, 60, respectively. -70, 45-55, 30-40, 20-28, 12-21 wt.%. .

The total content of dust and clay particles is 6-17%, clay content is 1.0-2.5%, grains larger than 0.071 mm contain 20-40% carbonate rocks, 60-80% quartz sand with inclusions of iron and aluminum. containing minerals.

Examples of the specific implementation of the mixture and its properties are given in Table 1 and 2.

The proposed coating has low water saturation and is formed faster than the known.
