Earth shoulder synchronous hilling construction method for preventing pavement structure layer from being polluted

Abstract

The invention provides an earth shoulder synchronous hilling construction method for preventing a pavement structure layer from being polluted. The method is characterized by: dividing a pavement andan earth shoulder jointly into a plurality of construction layers according to height, and performing construction on the construction layers layer by layer from bottom to top; during the constructionof each construction layer, firstly disposing a baffle along a boundary line between an earth shoulder area and a pavement area; adopting a geotextile to cover the baffle and extending the geotextileto the pavement area; then conducting hilling construction in the earth shoulder area until the hilling thickness and the compaction degree meet the requirements; removing the baffle, turning over part of the geotextile extending to the pavement area to cover the earth shoulder area, and covering one side, adjacent to the pavement area, of the earth shoulder area with the geotextile to realize isolation of the earth shoulder area and the pavement area; fixing the geotextile; carrying out construction in the a pavement area, and then extracting the geotextile. The method can effectively control the cross contamination problem in the earth shoulder construction process and improve the construction quality of the pavement entity and the earth shoulder.

Description

technical field [0001] The invention relates to the technical field of road engineering, and more specifically relates to a construction method for synchronous soil embedding of soil road shoulders for preventing pollution of road surface structural layers. Background technique [0002] The road shoulder is a belt-shaped part with a certain width located from the outer edge of the carriageway to the edge of the roadbed, and is generally composed of hard shoulders (including curb belts) and soil shoulders. The width of the soil shoulder is generally 0.75m or 1.5m. It is a part of the road adjacent to the hard shoulder or without a hard shoulder lane. It plays a role in protecting the stability of the side of the pavement structure layer. The construction quality of the soil shoulder directly affects the pavement structure layer. Edge construction quality and longevity. [0003] At present, fixed layered rolling is generally used in the construction of road shoulders. On the ...
