Problems solved by technology

A notable defect disclosed in the above-mentioned patent is that it needs to be heated to an extremely high temperature during specific construction, which not only requires a large amount of energy consumption, but also pollutes the environment, makes construction difficult, and it is impossible to add too much proportion to the composition. Polymers that limit the high-temperature stability of colored asphalt binders are not conducive to popularization and use. Therefore, the development and research of a new colored asphalt binder is highly anticipated by the relevant departments

[0039] It can be seen from the above table that the porosity of the mixture formed under the same conditions by adding FT paraffin to the colored asphalt binder decreases, indicating that its construction performance is improved. At the same time, the dynamic stability of the colored asphalt mixture also increases with the increase of FT paraffin Gradually increasing, indicating that its high temperature stability has been improved.

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...
