Abstract
In order to improve the width and pavement performance of municipal roads,four kinds of new materials(sulfur reinforced asphalt modifier,micro-surface slurry mixture asphalt,warm mixed asphalt mixture and polystyrene foam)were used to carry out roadbed reinforcement performance tests,and the bearing capacity,water stability,deformation resistance and economic cost of different materials were compared and analyzed.The results show that the performance of the roadbed reinforced by sulfur reinforced asphalt modifier and warm mixed asphalt mixture is the best,but the total cost of warm mixed asphalt mixture reinforcement scheme is 9%higher than that of sulfur reinforced asphalt modifier reinforcement scheme.In summary,it is recommended to use sulfur reinforced asphalt modifier as municipal road subgrade reinforcement material.关键词
