The Research On Temperature Changing Disciplinarian Of Asphalt Mixture For Material Transfer Vehicle

Temperature segregation is the non-uniform distribution of disproportion that quantity of heat loss during asphalt mixture is transported and discharged. lower temperature mixture is compacted so that road surface has asymmetric solid, more air clearance and higher roughness When asphalt mixture of temperature segregation is paved mat. The resulting pavement exhibits poor structural and textural characteristics and has a shorter life expectancy. At the same time, The resulting makes automobile consume more fuel and makes tyre abrasion become bigger and has an effect on traffic safety. Problems associated with temperature segregation are serious. Their elimination is essential to the production of high quality pavement. The task of this paper is researching the material transfer vehicle setting between a tipper and a paver, which deposits and mixes asphalt concrete again, to improving the uniformities of the materials and their temperatures, sending the mixtures to the paver at a constant velocity, and ensuring the uniformities of the mixtures and the steadiness of operating force in the process of paving. Through analyzing quantity of heat exchange on asphalt mixture with material transfer vehicle and outer environments,every part of asphalt mixture. Four energetics equations of asphalt mixture about four work modes are found while asphalt mixture is entered, transported,deposited and mixed asphalt concrete again in the material transfer vehicle. Adopting limited difference way to solution energetics equations. Causations that result in asphalt mixture quantity of heat losing are found out. Bring forward a few heat preservation measures of asphalt mixture on material transfer vehicle configuration . Process of temperature changing is simulated. The resulting may guidance spot construction and material transfer vehicle design.
