Research On Colored Warm Mix Asphalt Mixture And Pavement Technology

According to the domestic industry technology development trend and industry marketdemand, the paper mainly researchs on colored warm mix asphalt mixture and pavementtechnique. Through the colored pavement technology, the construction cost is reduced, andmake roads and the surrounding buildings art better coordinated and is more conducive tobeautify the city and induction of traffic, so as to enhance the city’s overall image and function,has a very good engineering practical significance.The technical principle of colored warm mix asphalt mixture and pavement technique isthe Sasobit and calcium stearate composite temperature mix technology. In the asphaltmixture by adding calcium stearate followed by another special temperature mix materialsunder the low temperature mixing, the most important thing is temperature mix technologyand color combination of asphalt technology. According to the hot mix color asphalt mixturestudied, the raw material technical indexes and mix is designed for indoor experimental study.Followed by the technology of warm mix asphalt performance research, by adding the organicadditives Sasobit, to reduce the asphalt viscosity at elevated temperatures, so as to achieve thepurpose of temperature and mixing, mainly study the different amount of Sasobit on asphaltand asphalt mixture performance influence. Through the research of this paper shows, theSasobit and sodium stearate composite warm mix asphalt technology can make the viscositydecrease, produce the mixture performance and can meet the code requirement and be appliedto actual engineering.Combined with calcium stearate using Sasobit warm mix technology, colored asphaltmixture and warm mix asphalt mixture are combined to make construction greatly reduce thetemperature, which saves construction costs, and also reduces harmful emissions. Thetechnology has good energy conservation, energy, environmental benefits, has a greatpractical significance.
