Problems solved by technology

However, the initial strength of the existing emulsified asphalt is low, which cannot meet the application requirements of important projects such as heavy-duty traffic roads and expressways.
In addition, the softening point of emulsified asphalt is usually 46-55°C, the high temperature resistance is not good, and the bonding strength is low. Especially in areas with high temperature weather and large vehicle load, it is easy to cause high temperature deformation of asphalt roads and interlayer adhesion. Insufficient and other defects greatly reduce the performance and service life of emulsified asphalt

Abstract

The invention provides composite emulsified asphalt and a preparation technology thereof. The composite emulsified asphalt is prepared from the following components: matrix asphalt, petroleum tar, polybutylene, EVA (ethylene-vinyl acetate), pentaerythritol, 8-hydroxyquinoline, lauryl alcohol phosphate acid ester, vinyl versatate, propylene glycol block polyether, Turkey red oil, oleamide, epoxy ethanediamine ethylene diamine, aminated lignin, bentonite, phosphonolipid betaine, water, sodium dodecyl benzene sulfonate, ammonuim humate, hydrochloric acid, ammonium chloride, beta-butyrolactone and ethylene bis stearamide. The prepared composite emulsified asphalt has the advantages that the shear strength is 1.12 to 1.23MPa at the temperature of 25 DEG C, and is 0.59 to 0.74MPa at the temperature of 60 DEG C, the adhering strength is good, and the high temperature-resistant property is better; the softening point is higher than 63 DEG C, the needle penetration is 68 / 0.1mm at the temperature of 25 DEG C, the comprehensive property is excellent, and the application requirement of road construction projects can be met.

Description

technical field [0001] The invention belongs to the technical field of asphalt, and in particular relates to a composite emulsified asphalt and a preparation process thereof. Background technique [0002] Emulsified asphalt is widely used in road construction projects, such as micro-surfacing for road maintenance and repair, slurry seal layer, adhesive layer between pavement layers, and waterproof layer for road and bridge surfaces. Emulsified asphalt is formed by mechanically processing and dispersing asphalt, water and emulsifier into asphalt particles suspended in water. With the rapid development of social infrastructure, the requirements for emulsified asphalt are getting higher and higher. However, the existing emulsified asphalt has low initial strength and cannot meet the application requirements of important projects such as heavy-duty traffic roads and expressways. In addition, the softening point of emulsified asphalt is usually 46-55°C, the high temperature res...
