Applied Study On Eliminating Snow By Self-stress Of Polyurethane Rubber Particles Mixture

Problems of the snow-covered road were seriously affected traffic safety. Therefore,researchers around the world have made unremitting efforts. After the study that the use ofbreak the ice road is an effective means to address these challenges. From study abroad andour experience，This paper presents a new method which is polyurethane used as a binder tothe road. Polyurethane strength and flexibility after curing, coupled with the high elasticityof the rubber particles used can be, polyurethane mixture can be effectively achieved by itsown deformation purpose break the ice with a significant social and economic value.In this paper, scrap rubber granules mixed polyurethane raw material indicators wereanalyzed by laboratory tests. Draw on existing experience and frost road grading with theactual situation to determine a reasonable gradation type, ensuring the structural stability ofthe mix. Then mix for road performance and durability are analyzed experimentally，Theresults prove that the use of polyurethane adhesive polyurethane scrap rubber particles mixwith good road performance and durability，It mixes the pavement break the ice and lay asolid foundationThen，the use of an indoor ice tester developed for polyurethane scrap rubber particlesmix icing test results evaluation and analysis of a different rubber particles mixed pairingrules in addition to the effect of snow and ice. According added deicing salt test results alsodraw on the Prior conservation and afterwards conservation approach can significantlyimprove the self-stress effects of deicing road de-icing.Finally, we use numerical simulation method and using ANSYS software analysis atdifferent temperatures and different rubber particles production factors polyurethanemixture ice mechanism, their impact law were summarized.
