Study On Application Of Plant Mix Cold Recycling Emulsified Asphalt Technology In Municipal Road Base

With the substantial increase in road traffic, vehicle overloading, etc. are becoming increasingly serious damage to the road surface is also accelerating. For the renovation of the road reconstruction will produce a large number of abandoned old asphalt pavement materials, resources and the environment which have caused a very serious impact. Aiming at this problem studied, Recycled asphalt pavement material(RAP) re-use, through a variety of experiments confirmed RAP material, it can be replaced by a new stone, layers of different roles in different structures on the road. Use emulsified asphalt cold recycling design, recycling asphalt mix design as raw material for cold recycled mixture of emulsified asphalt paving, compaction, and detects road performance, again to verify compliance with construction standards. However, problems still exist locally, therefore, this paper proposes a new design method, accurate volumetric method design, and this method is verified by tension and compression strength test, splitting tests to evaluate the workability of the mix of work and to determine the optimum moisture content and mixing water. Mixture Performance exact volume method superior design than the traditional design methods for construction inspection. This will not only solve the problem of waste asphalt may affect the environment, but also developed a new resource.
