Evolution of Colored Asphalt Technology: From Material Improvement to Performance Grading
Research on colored asphalt pavement technology dates back to the 1950s, with European and American countries pioneering related explorations.
Overview of Development History
Research on colored asphalt pavement technology dates back to the 1950s, with European and American countries pioneering related explorations. In the 1960s, institutions such as the USSR Road Research Institute and Kharkiv Highway Institute conducted systematic research and applied verification on the construction of colored asphalt concrete pavements. In the early 1980s, several Chinese cities initiated technical discussions on colored asphalt concrete pavements. After decades of development, this material has been recognized globally by the engineering community as a novel paving technology, classified under the category of “new green building materials.”
Product Grading System
Based on differences in road performance, colored asphalt has developed a relatively detailed product grading system. Taking the LS series colored asphalt as an example, it can be categorized into three main types: matrix-type, modified-type, and specialty-type, catering to the diverse demand tiers of the colored paving market. The establishment of this classification system signifies the evolution of colored asphalt from a single product toward a series of functionalized products.
Process Technology Advancements
Production facilities for colored asphalt have adopted a modular configuration. A typical process flow involves heating rubber oil before transferring it to a reactor. Petroleum resin, SBS modifier, and pigment are fed into the reaction system via a batching and conveying system. The binder is prepared through the combined action of a high-speed dispersing mixer and a high-shear emulsifier. Beyond hot-mix technology, cold-laid colored pavement techniques and colored emulsified asphalt preparation processes are also evolving, offering greater flexibility for diverse construction conditions.
Technical Specifications and Quality Evaluation
Technical requirements for colored asphalt have been incorporated into the industry standard system. According to CJJ/T 218-2014 “Technical Specifications for Colored Asphalt Concrete Pavements on Urban Roads,” the three primary indicators of colored asphalt (penetration, softening point, and ductility) must meet the technical requirements corresponding to the respective grades of road petroleum asphalt. Clear specifications and field verification methods have been established for key performance indicators such as Marshall stability, residual stability after water immersion, dynamic rutting stability, and residual strength ratio after freeze-thaw splitting.
