Rubber Particles In Asphalt Surface Construction Technology

Rubber particles in asphalt mixture is the break waste rubber into meet certain indicators of rubberparticles, in the form of aggregate directly added to the common asphalt mixture, instead of a part of theaggregate to form a new type of asphalt mixture. Because of the rubber particles with high elasticity, tosome extent changed the status and stress of the pavement surface layer of ice and snow and cement roadsurface condition, so that the rubber particles in asphalt pavement with the de-icing ability. But also makesthe mixture of rubber particles construction change. Are mainly high elastic rubber particles to a certainextent changed the physical properties of asphalt concrete. This needs us to make corresponding change onthe construction technology and breakthrough.Laboratory index, the study of rubber particles in asphalt concrete, Harbin industrial university,wuhan university of technology and some of the chang ’an university research has more mature. However,their research is mainly done in the laboratory characteristics of materials research. In the end, we areapplied to rubber particles in asphalt road surface pavement, so in this paper, we mainly theoreticalresearch on construction technology for asphalt rubber particles. Include mixture, transportation, pavingand rolling all aspects such as construction quality control.(1) mixing of rubber particles in asphalt concreteThrough analyzing the characteristics of rubber particles in asphalt, rubber asphalt concrete mixingprocess and the general asphalt concrete mixer has some special requirements, must first to calibrationstation. Through to the equipment calibration to ensure all kinds of rubber particles in asphalt mixtureaggregate, mineral aggregate and asphalt and rubber particles dosages of precision meet the requirementsof the grading and thus ensure that rubber particles in asphalt mixture pavement deicing performanceperfect embodiment. According to the experiments of rubber particles in asphalt mixture, and availableinformation in our common asphalt concrete mixing scheme and the mixing way different. Rubberparticles in asphalt mixture is mix rubber particles and aggregates together first, after a certain time andthen to spray asphalt and mineral powder feeding. We mainly through the analysis of theory, combinedwith practical experience in mixing time parameters and temperature requirements of each process.(2) of the rubber particles in asphalt concrete pavingCombined with physical and chemical properties of rubber particles in asphalt concrete, again according to the paved road structure, and its actual effect is ice antiskid, we define the paving belongs tothin layer of rubber particles in asphalt surface thickness paving construction category. In order to ensurethe quality of road surface paving process, combining with the characteristics of the rubber particles inasphalt, through to the paver screed kinematics mechanism is studied, and the mechanism of balance beamleveling system analysis. To develop a paving scheme can satisfy the above requirement.(3) of the rubber particles in asphalt concrete crushBecause of the rubber particles in asphalt concrete has a great deal of resiliency, so used in rollingprocess with ordinary asphalt concrete is also have very big distinction. According to the formingcharacteristics of rubber particles in asphalt concrete, referring to the research results of Dr Zhou ChunxiuHarbin industrial university, the second molding method of rubber particles in asphalt mixture. Weformulate the corresponding construction at the scene of a set of rubber particles in asphalt concreteconstruction plan.
