    Abstract
  • The impact of adding rubber particles on the water stability, wear resistance and other road performances of slurry mixture were compared by using wet track abrasion test, load wheel test and stability and resistance to compaction test.The attenuation characteristics of tyre vertical vibration that happened on micro-surfacing adding rubber particles were studied through tyre-road vibration test device.Test result shows that the workability of slurry mixture is improved by adding rubber particles, the mixing time is prolonged, the early strength decreases by a small margin, and bitumen aggregate ratio is needed to raise by about 1% to achieve the same road performance.When the content of rubber particles is not more than 5%, the requirement of wheel rut deformation on micro-surfacing pavement is met.Comparing with traditional micro-surfacing pavement, the attenuation coefficient of vertical vibration increases by 3%-13% on micro-surfacing pavement adding 2%-5% rubber particles overlayed asphalt pavement, and the attenuation coefficient of vertical vibration increases by 16%-24% on that overlayed cement pavement.
