Abstract

The invention belongs to the technical field of road engineering construction, and particularly relates to a high-viscosity asphalt modifier porous asphalt pavement construction method. The high-viscosity asphalt modifier porous asphalt pavement construction method is characterized by sequentially including the steps that construction equipment prepares to work; the mixing proportion of a direct-putting high-viscosity asphalt modifier porous asphalt mixture is designed; the direct-putting high-viscosity asphalt modifier porous asphalt mixture is produced; the direct-putting high-viscosity asphalt modifier porous asphalt mixture is transported; preparation work is conducted before the direct-putting high-viscosity asphalt modifier porous asphalt mixture is laid; use parameters of a laying machine are selected and adjusted; laying work is conducted; the direct-putting high-viscosity asphalt modifier porous asphalt mixture is rolled and formed; joint treatment is conducted. The method has the advantages of obvious construction method advantages and economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of road engineering construction, and in particular relates to a construction method of a high-viscosity asphalt modifier permeable asphalt pavement. Background technique [0002] At present, the storage of finished high-viscosity modified asphalt is limited by the conditions of heat preservation, heating, modification or adding asphalt tanks, which brings a lot of inconvenience to production and construction. When the finished high-viscosity modified asphalt is stored, a special asphalt tank must be installed and stirred continuously to prevent temperature segregation and separation of different phases. It needs to be heated in advance during production, and the storage tank must be occupied and heated for heat preservation if it cannot be used up at one time. In addition, for the high-viscosity modified asphalt tanks that have been stored repeatedly, the residue is not easy to clean up, and the temperature...
