Research On Application Technology Of Warm Mixture

Based on the comprehensive analysis of the viscosity-temperature characteristics of different temperature modifiers and different viscosity reduction techniques,the warm mix asphalt pavement performance under different dosage was studied,the mechanism of viscosity reduction of warm mix asphalt was revealed.Through the temperature mixing modified asphalt pavement,the social and economic benefits of the warm mix asphalt mixture were analyzed,which effectively promote the temperature mixture in the field of road promotion and application.It has an important practical significance for promoting energy conservation and environmental protection in road construction.(1)The viscosity variation characteristic of asphalt was systematically analyzed,the existing agents and the viscosity reduction mechanism were investigated and analysed.Ultimately,the difference between the hot mix asphalt and warm mix was comprehensively analysed.(2)The technical specifications of raw materials were tested,and the viscosity-temperature property of asphalt was analyzed,ultimately,the mixing optimum temperature and optimum compaction temperatures were determined.(3)The Marshall Test Method was used to design warm mix asphalt mix,and the porosity was used to study the mixture mixing and compaction temperatures,the performance of mix asphalt pavement was evaluated.(4)To rely on physical engineering,the warm mix asphalt pavement was paved,and the pavement performance and the compaction effects were tested,the performance of warm mix asphalt mixture was verified,and the social and economic benefits of warm mix asphalt were clearly defined.
