kinematic viscosity at high temperature, been attributed to the presence of the S wax with high hydrocarbons molecular content in the binder, which is expected to improve the viscosity properties of the modified binder and enhance its resistance to deformation when used in warm asphalt concrete mixtures.
Each of the modifiers plays a unique role in the performance the high viscosity asphalt. Through a particular modification technology, the optimum dosages of polymer,
High viscosity modified (HVM) asphalt was prepared by the addition of styrene-butadiene-styrene (SBS), plasticizer, crosslinker. The effect and proportion of each modifier in the preparation of HVM asphalt were studied. SBS was the major modifier and determined the basic properties of HVM asphalt.Published in: Polymer Composites · 2017Authors: Feng Zhang · Changbin HuAffiliation: Fuzhou University
High-viscosity modified (HVM) asphalt was prepared by the addition of styrene–butadiene–styrene, furfural exact oil (FEO, plasticizer), sulphur (crosslinker).
High viscosity asphalt binders (HVABs) were developed by Japanese companies to improve rutting resistance and durability of porous asphalt . HVABs are compound modified asphalt binders, which are mainly modified by styrene–butadiene–styrene (SBS), mineral oil and petroleum resin .

The composite high-viscosity modified asphalt prepared by using the method has the characteristics of stable heat storage, and excellent high and low temperature properties, has good economic benefits and environmental effects because of use of waste rubber, and is free of sulphur as a stabilizer, the construction viscosity can be reduced, the
RTFOT Viscosity Grade Bitumen (AR-Grades), in which the Viscosity of bitumen (asphalt) is measured at 60 °C (140 °F) after the roll on thin film oven test. Viscosity grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures.
The procedure of preparation of high viscosity modified bitumen in the laboratory is as follows: First, the matrix bitumen is heated to 140 °C and melt in an iron container. Then, high viscosity modified bitumen is made by mixing the bitumen with the high viscosity additives by a shearing speed of 3000 r/min in a mixer.

The application of crumb-rubber modifier (CRM) in asphalt mixtures has been proven to increase the viscosity of CRM binders. In recent years, warm mix asphalt (WMA) additives have been employed to CRM binders to lower their viscosity at high temperatures, allowing a decrease in the mixing and compaction temperatures.
