Abstract

The invention discloses an emulsified asphalt used for slurry seal and micro-surfacing. The emulsified asphalt contains the following components in weight proportion: 30-80 parts of asphalt, cationic emulsifier C-450 with asphalt accounting for 0.1-5%, 30-52 parts of water at 30-80 DEG C, a trace amount of inorganic salt stabilizer, and concentrated hydrochloric acid with pH value in the range of 1.5-7.0. The product is mainly applied on slurry seal technology, for example, reconstruction of old asphalt pavement, seal coat of new asphalt pavement, overlay of wearing layer on sand-gravel road, maintenance of cement concrete and bridge surface, etc. The emulsified asphalt can improve construction environment and prolong construction period without changing the performance thereof; and also can reduce noise and environmental pollution.

Description

A kind of emulsified asphalt for slurry seal and micro-surfacing and preparation method thereof 【Technical field】 The invention relates to the fields of road engineering and bridge pavement, in particular to a preparation process of slurry seal layer and ground emulsified asphalt for micro-surfacing. 【Background technique】 Asphalt has unique rheological properties, and has become an indispensable infrastructure material for transportation, construction and other industries due to its excellent properties such as good adhesion, aging resistance, and water resistance. However, in order to ensure the fluidity and workability of asphalt during road application, a large amount of fuel needs to be consumed and many pollution problems arise. Therefore, in the use of asphalt, how to solve its fluidity, save resources, reduce energy consumption, and protect the environment has attracted widespread attention. In recent years, as a means of saving energy, reducing consumption and re...
