(1) by high-performance at low temperature. From GS-1 to GS-8 a total of 8 models, that is, the type of asphalt modified high performance and low temperature, the nature of the performance of elastomer; model on the extension of the low-temperature heat, but decreased performance, performance-plastic body with the nature of the ideal Flexibility to resume
(2) according to the functions of the sub-type. In addition to the GS-1 used as a normal PSBR modified asphalt agent, can also be done by extension agent specifically designed to upgrade bitumen.
(3) GS-6 performance of high-temperature, softening point of asphalt can reach more than 80 ℃ for Climate of High Temperature conditions and special requirements of road construction projects.
(4) GS-7 modified asphalt and the toughness toughness Visco results. Accession to the 3% -5% of the modified agent JTGF40-2004 sufficient to meet the standards of SBR modified asphalt type of toughness toughness Visco and technical requirements, it is unable to meet the bulk of the SBR.
(5) GS-8-PSBR is designed to produce high viscosity modified asphalt, adding 5% -6% of such modifiers, viscosity and characterization of the role of adding more than 12% of the other modifier, a semi-reactive material Times.
