Abstract
The invention discloses high fluidity grouting modified asphalt and a preparation method thereof. The high fluidity grouting modified asphalt comprises, by mass, 38.5%-63.55% of matrix asphalt, 30%-50% of C9 petroleum resin, 1%-3% aromatic oil, 4%-6% a SBS modifier and 1.5%-2.5% of hydroxyethylethylene bis-stearamide. The high fluidity grouting modified asphalt has high hardening strength, good stability and good flow performances.
Description
technical field [0001] The invention belongs to the field of building materials, and in particular relates to a high fluidity grouting modified asphalt and a preparation method thereof. Background technique [0002] With the high-speed and heavy-duty of highway and urban road transportation, it has brought severe challenges to the construction and operation of road infrastructure. Under the comprehensive effects of excessive traffic load, improper design and construction, and natural factors, some road bases and subgrades have suffered damage of different types and degrees, mainly in the form of cracks, ruts, potholes, and local subsidence. Grouting technology is one of the common rapid road maintenance methods. At present, road grouting in my country is mainly made of cement-based and geopolymer materials. Cement-based slurry material has low cost, high stone body strength and strong impermeability, but due to the characteristics of cement material itself, there are disadv...
