Abstract

The invention discloses a coloured asphalt cement, preparing method and application, which is characterized by the following: including 1-5% FT ceresin wax; introducing little FT ceresin wax to decrease the processing temperature; decreasing the odor of cementing agent; making the coloured asphalt cement with better high temperature stability.

Description

technical field [0001] The invention relates to an asphalt binder, in particular to a binder for colored asphalt pavement. Background technique [0002] Colored asphalt pavement has been widely used in highways, bicycle lanes, sidewalks, bus lanes, pedestrian areas, squares and home driveways. [0003] The mechanical properties and rheological properties of colored asphalt binder are the same as those of general road heavy traffic asphalt. The main principle of colored asphalt binder pavement is to use colored asphalt binder and add various pigments to make it have various required colors. At the same time, by using colored stones or light-colored stones, it can have a longer-lasting color effect. A good colored asphalt binder should meet the following requirements: [0004] Colored asphalt binder has good performance and should try to meet the requirements of heavy traffic asphalt or even modified asphalt; good high temperature stability; good water damage resistance; good...
