Abstract

The invention discloses a cementing material for a colored pavement and a manufacturing method thereof. The cementing material mainly comprises heavy mineral oil, petroleum resin C5 and / or C9, SBR, SBS, PE, PP and / or PS. The manufacturing method comprises the following steps of: firstly, adding materials into a reaction kettle, and stirring and mixing the materials; secondly, shearing the mixture by using a high-speed shearing machine; and finally, discharging air bubbles generated by the stirring to prepare a finish product of the cementing material. The cementing material for the colored pavement has the advantages of high temperature-sensing performance, high temperature deformation resistance and low temperature fission resistance.

Description

【Technical field】 [0001] The invention relates to a pavement material, in particular to a cementitious material for colored pavement and a manufacturing method thereof. 【Background technique】 [0002] With the further development of our country's economy, the application range of colored asphalt pavement will become larger and larger. It plays a positive role in beautifying the environment and promoting the safety management of traffic engineering. The main principle of colored asphalt pavement is to use cementitious materials for colored paving, and to make it have the required color by adding various colors. The mechanical properties and rheological properties of the binder for colored pavement are similar to those of general road heavy traffic asphalt. A good binder for colored pavement should meet the following requirements such as: temperature sensitivity, rutting resistance, and crack resistance Wait. It is just what the society needs to provide a binder for color pa...
