Abstract

The invention discloses colorful asphalt latex, a preparation method thereof and an application of the colorful asphalt latex in colorful slurry seal coat. A colorful asphalt cementing agent, an emulsifying agent, an additive and water are mixed and stirred according to certain ratio to prepare the colorful asphalt latex. The colorful asphalt latex, inert solid, a colorant and water are stirred to prepare colorful slurry mixture, and then paving construction is performed to prepare the colorful slurry seal coat. The colorful slurry seal coat has simple manufacturing technique, not only can be applied to the paving of a colorful slurry seal coat road surface but also is applied to the aspects such as the maintenance of an old asphalt road surface, the paving of a wearing coarse on the sand-gravel surface, and the maintenance of a cement concrete roadway and a bridge deck, reduces the cost of road maintenance, and increases the prior road friction coefficient; the striking color has good landscape and alarm function, high application value and high popularization value.

Description

Technical field [0001] The invention relates to a colored asphalt emulsion and a preparation method thereof. [0002] The invention also relates to the application of the colored asphalt emulsion in the colored slurry seal layer. Background technique [0003] The color slurry seal is made by mixing appropriately graded aggregates, fillers, emulsified asphalt, water, additives and special colorants and other raw materials in a certain proportion to make a uniform slurry mixture, and according to requirements The thickness and width of the paving on the pavement. The color slurry seal construction can produce significant economic and social benefits whether it is for low-grade roads or high-grade roads, whether for urban roads or landscape roads. The color slurry seal can quickly repair the abrasion, aging, cracks, smoothness, looseness and other diseases, play the role of waterproof, anti-skid, leveling, wear resistance, etc., and the color slurry seal has low engineering cost on ...
