Evaluation of Asphalt Mixture Paving Segregation and EDEM Simulation Optimization of Spiral Distributor
摘要
Abstract
The actual service life of asphalt concrete pavement is much lower than the design life due to the lack of grading design,on-site construction technology and follow-up maintenance.Therefore,through dynamic asphalt mixture,anti-segregation test and simulation to analysis three different screw diameters and select the optimal screw diameters.It is concluded that in the simulation model,the simulation segregation of 460mm screw diameter is small,and the screw distributor with larger diameter and lower speed is selected in the actual site construction,and the height of the mixture in the distributor is reasonably adjusted to make the mixture full of the screw distributor.关键词
