Cycloalkyl heavy traffic asphalt modification stabilizer

Abstract

The invention provides a special modification stabilizer for cycloalkyl heavy traffic asphalt. The special modification stabilizer is prepared from a cross-linking agent, an accelerant, an activatingagent, an inorganic filling agent and a viscosity improver; the dosage of each component is as follows in parts by weight: 10 to 90 parts of the cross-linking agent, 1 to 50 parts of the accelerant, 1to 50 parts of the activating agent, 5 to 95 parts of inorganic soil and 5 to 90 parts of the viscosity improver, wherein the cross-linking agent is prepared from sulfur, sulfide and calcium petroleum sulfonate and the mass ratio of the sulfur to the sulfide to the petroleum sulfonate is 1 to (0.2 to 0.5) to (0.1 to 0.3); the adding amount of the sulfide and the petroleum sulfonate is determinedbased on the sulfur. By adopting the modification stabilizer provided by the invention, high temperature and low temperature performance of modified asphalt prepared by the cycloalkyl heavy traffic asphalt is remarkably improved, and the attenuation of segregation and performance indexes of the modified asphalt prepared by the cycloalkyl heavy traffic asphalt is reduced; the storage stability is improved and the high-temperature viscosity is reduced; the construction workability of the modified asphalt prepared by the cycloalkyl heavy traffic asphalt is improved and the viscosity at 135 DEG Cis remarkably reduced.

Description

technical field [0001] The technology belongs to the field of petrochemical industry and relates to a special modified stabilizer for heavy traffic asphalt and the SBS modified asphalt prepared therefrom. Background technique [0002] With the development of social economy, the traffic volume continues to increase, and the proportion of heavy-duty vehicles is increasing, which brings huge challenges to the quality of the road surface. Many newly-built asphalt pavements have serious problems such as bulging and breaking. The reason is mainly due to insufficient high temperature stability of pavement materials. As the most important component of pavement materials, asphalt plays a decisive role in pavement quality. An ideal asphalt material should meet the following requirements: greater stiffness at high temperature, less stiffness at low temperature, and presence of water The anti-stripping effect is good, and SBS modified asphalt can meet the above requirements in a balanc...
