Cement for preparing colored asphalt and preparation process thereof

Abstract

The invention discloses cement for preparing colored asphalt, prepared from 30-40 parts of rubber oil, 40-50 parts of C9 petroleum resin, 4-12 parts of SBS (styrene butadiene styrene) modifier, 0.5-3 parts of an antiaging agent, 8-15% of terpene resin, and 1-5 parts of diatomite. The cement of the invention has high softening point and high-low temperature ductility, which indicates that the cement has good high-low temperature stability; results of a tensile test on the cement show that the cement has high-low temperature toughness, which means that the cement has good low-temperature flexibility and good impact resistance, and the cement is up to 60-80% in elastic recovery which means that the cement has good elastic recovering performance and can well self-heal from deformation caused by loading effect; the light color cement includes higher polar aromatic components, the adhesion of the cement measured by boiling method may reach level 5-6 without adding any anti-stripping agent, which indicates that the cement has good adhesion.

Description

technical field [0001] The invention relates to a cementing material formula for preparing colored asphalt with reasonable process, simple formula, high toughness, high elasticity and high stability and a preparation process thereof. Background technique [0002] European and American countries began to study and try to apply colored asphalt concrete pavement in the 1950s. In contrast, my country's exploration in this area only started in the early 1980s, and achieved little success. Compared with the black asphalt concrete pavement, this kind of pavement can not only beautify the city and improve the road environment, but also play the role of traffic warning and divert traffic flow. taste. In recent years, colored asphalt concrete pavement has been used more and more in places such as highways, urban roads or squares, which has aroused people's widespread interest and concern. [0003] Binder is the main component of colored asphalt mixture, and its performance directly...
