| Abstract: | Asphalt from Karamay naphthenic heavy crude was modified by SBR using SBR powder dispersed by mother liquid mixing process. The product qualities could meet the specifications of SBR modified road asphalt (JTG F40-2004) issued by China Ministry of Communications. Various performance test results showed that the product possessed good toughness and tenacity, excellent thermal stability during storing and good road performance at high-low temperatures. According to the SHRP standard evaluation, said product satisfied the requirements of PG64-28. |
