The effect of asphalt emulsion type on the characteristics of cold asphalt emulsion mixtures

Abstract

The need for road infrastructure continues to increase affecting the increase of hot asphalt mixtures. Hot asphalt requires a lot of energy to use because it goes through a heating process, so Cold Emulsion Asphalt Mixture (CAEM) is widely studied to be an eco-friendly alternative to hot asphalt mixtures. This study used a type of mixture IV Asphalt Emulsion Mixture with 4 types of emulsified asphalt, which are Cationic Slow Setting-1 hard (CSS-1h), Cationic Medium Setting-2 (CMS-2), Cationic Rapid Setting-2 (CRS- 2), and Cationic Quick Setting-1 hard (CQS-1h). The test was carried out using the Marshall Test method and the parameters value of each type of emulsified asphalt was calculated. The test results are compared with their characteristics to determine the most suitable type of emulsified asphalt for heavy traffic in Indonesia. The results showed that CRS-2 emulsified asphalt was not recommended because it had low stability and did not meet the parameter requirements. The use of CQS-1h is recommended because at an early age it can produce high stability value and meet all requirements.
