Asphalt as a temperature susceptibility of the viscos-elastic plastic materials, it isprovided with the required viscosity in mixing at high temperatures, Therefore in roadconstruction Mainly used the hot mix asphalt, However, due to the construction of hightemperature, resulting a series of questions in asphalt aging, harmful emissions and energyconsumptionTibetan Plateau due to the high altitude, low air pressure, Increased the temperaturedifficulties, low power of construction machinery, roller compacted is not dense,leading tohot-mix asphalt mixture is difficult to reach the construction effect of low-lying areas,Develop a new type of retardable viscosity’s Asphalt reduce the high temperature viscosityand increases the low temperature viscosity, slowly increasing asphalt intermediatetemperature viscosity have a Important significance to improve these shortcomings of roadconstruction.According to the requirements of retardable viscosity asphalt and analysis the principleof retardable viscosity, design the molecular to achieve the desired performance and synthesis,synthesis a new retardable viscosity thinner, analysis performance of the SK Asphalt, thepanjin Asphalt and SBS modified asphalt after Mixing retardable viscosity thinner, Indicatingviscosity of retardable viscosity’s lower than the asphalt and Performance has increased, theability to reach or exceed the performance of the Tibet region130#asphalt, it has a broaderscope of application, retardable viscosity’s asphalt could meet The use of performance at thesame time process performance. Through research the cooling characteristics of the retardableviscosity’s Mixture Asphalt and pavement performance test, Mixing and compactiontemperatures of the retardable viscosity’s Mixture Asphalt can reduce10~15℃than asphaltmixture, Energy conservation, extend the construction time, meet the requirements of roadperformance
