Embodiment Construction

[0044] The invention is a modified emulsified asphalt, the main materials are ordinary emulsified asphalt, water-based epoxy resin emulsion and curing agent, wherein the water-based epoxy resin emulsion and curing agent are modified materials. The emulsified asphalt was modified with the above-mentioned modified materials, and the incorporation amount of the modified materials, namely water-based epoxy resin emulsion and curing agent, into the emulsified asphalt was determined. The weight percent of each component is: 100 parts of ordinary emulsified asphalt, 3-15 parts of water-based epoxy resin emulsion, and the amount of curing agent is 20%-25% of the water-based epoxy resin emulsion.

[0045] 1. Before using the water-based epoxy resin emulsion for the first time, place the container containing the water-based epoxy resin emulsion upside down, let it stand for about 10 minutes, and then shake it well to make the water-based epoxy resin emulsion in the container evenly distr...

Abstract

The present invention relates to emulsified asphalt modified by adopting water-base epoxy resin. It is characterized by that it utilizes water-base epoxy resin emulsion and solidifying agent to modify the emulsified asphalt, in which the general emulsified asphalt content is 100 portions, water-base epoxy resin emulsion content is 3-15 portions and the solidifying agent content is 20%-25% of water-base epoxy resin emulsion content.

Description

technical field [0001] The invention relates to modified emulsified asphalt used for asphalt pavement maintenance and repair, in particular to emulsified asphalt modified by water-based epoxy resin. Background technique [0002] With the rapid development of the national economy, the increasingly heavy traffic load, the substantial increase in traffic volume, and the increasing severity of overloaded vehicles have accelerated the damage of asphalt pavement. Therefore, strengthening the research on the maintenance and repair technology of asphalt pavement and how to prolong the service life of asphalt pavement has a good market prospect. [0003] The asphalt pavement partial repair technology with emulsified asphalt as bonding material has many advantages such as wide application range, convenient construction, energy saving, pollution reduction, and construction period reduction. Insufficient and other shortcomings, thus restricting the promotion and application of emulsifi...
