Preparation of color modified emulsified asphalt and performance analysis of micro surface mixture in cold area

In order to determine the color modified emulsified asphalt and its preparation process in cold areas represented by Hulunbuir, Inner Mongolia, a variety of materials such as saturated hydrocarbon A, petroleum resin B, copolymer C, copolymer D, and plasticizer E were selected to simulate four components of asphalt are used to prepare colored asphalt, and a colored modified emulsified asphalt suitable for cold regions is developed by the preparation process of emulsified asphalt emulsifying and modifying. The performance of the prepared colored modified emulsified asphalt was analyzed, and the optimal dosage range of modifier, emulsifier, stabilizer, and pH adjuster was determined, and the high and low temperature performance of colored modified emulsified asphalt was improved to adapt to environment of cold areas. Through the colored micro-surfacing mix design to determined the optimal emulsified asphalt dosage, and the test compares the surface performance and durability of the ordinary micro-surfacing mixture and the colored micro-surfacing mixture, which proves that the CMS-3 type mixture has good water sealing effect, anti-slip performance and ability of water damage resistance.
