Embodiment Construction

[0024] Such as figure 1 As shown, a temporary road RCC pavement reconstruction structure is provided with a concrete road slab 2 on the subgrade 1 whose flatness is not greater than 10mm after shoveling, leveling and compaction treatment, and drainage is provided on both sides of the concrete road slab 2 ditch3. Wherein the concrete road slab 2 is formed by rolling the roller compacted concrete paved on the roadbed 1, and the paving thickness is 30-35 cm. The surface of the concrete road slab 2 is sawed with transverse shrinkage joints every 10-15m. The width of the shrinkage joints is 1cm and the depth is 6cm. The joints are filled with asphalt and horseshoe grease.

[0025] In this embodiment, the roller compacted concrete for pouring the concrete road slab 2 is mixed with cement, water, GQ202 type retarding water reducer, sand, 5-20mm gravel and 20-40mm gravel, and the amount of cement is 277kg / m 3 , The weight ratio between the components of RCC is cement: water: GQ202...

Abstract

The invention relates to a temporary road roller compacted concrete pavement reforming structure and a construction method thereof. A purpose of the present invention is to provide a temporary road roller compacted concrete pavement reforming structure with characteristics of convenient construction, low cost and short maintenance time, and a construction method thereof. The technical scheme of the present invention is that a concrete road surface plate is arranged on a subgrade being subjected to leveling and filling compaction, and is formed by rolling roller compacted concrete spread on thesubgrade, a plurality of horizontal contraction joints are sawn on the surface of the concrete pavement plate, the contraction joints are subjected to crack sealing with stone mastic asphalt, and theroller compacted concrete is formed by mixing cement, water, a GQ202 type retarding water reducer, sand, 5-20 mm gravel and 20-40 mm gravel. The temporary road roller compacted concrete pavement reforming structure of the present invention is suitable for temporary road pavement reforming and other projects.

Description

technical field [0001] The invention relates to a temporary road roller compacted concrete pavement reconstruction structure and a construction method thereof. It is suitable for temporary road pavement reconstruction and other projects. Background technique [0002] Temporary roads for construction or personnel passage are dirty and messy with water and mud in rainy days, seriously affecting traffic; at the construction site, the above-mentioned roads are in poor safety and civilized image, which affects the overall appearance of the project. However, conventional concrete pouring costs are high, the construction process is complicated, and the maintenance time is long, so it is not suitable as a temporary road on the construction site. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a temporary road roller compacted concrete pavement reconstruction structure and its construction method with convenient construc...
