Cement stabilized macadam base layer steel die supporting continuous laying system and construction method

Abstract

The invention relates to a cement stabilized macadam base layer steel die supporting continuous laying system and a construction method. The supporting continuous laying system comprises a double-layer steel die supporting system and a base layer joint slope supporting section supporting device. An elevation accurate control system is symmetrically arranged on the outer side of the double-layer steel die supporting system, the double-layer steel die supporting system is arranged on the two sides of a base layer, and the base layer joint slope supporting section supporting device is arranged inthe position of a transverse joint and matched with a special joint slope section device. Two cement stabilized macadam laying devices are adopted for conducting laying layer by layer, and longitudinal and transverse joint treatment measures are optimized. By the adoption of the related cement stabilized macadam base layer steel die supporting continuous laying system and the construction method,the elevation accurate control system and the double-layer steel die supporting system are adopted, two layers are continuously laid, the situation that an upper base layer can be laid only after a lower base layer reaches the required strength is avoided, a construction process and the structure are simple, operability is high, the application range is wide, input materials are few, a construction period is short, and technical and economic benefits are good.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and relates to a construction method of a cement-stabilized gravel base, in particular to a cement-stabilized gravel base steel form support continuous paving system and a construction method. Background technique [0002] With the continuous improvement of our country's transportation level and the continuous increase of heavy-duty vehicles, road engineering is developing in the direction of high bearing capacity and high standards. Fast construction, low cracks and other properties, cement stabilized macadam as a semi-rigid base material is more and more favored by construction units and design units. [0003] As a semi-rigid pavement base, cement-stabilized macadam base is widely used because of its advantages such as good slab performance, high strength, fast initial strength growth, excellent mechanical properties, good water stability and certain frost resistance. on roads of all ...

Problems solved by technology

However, due to the unscientific construction technology, it is difficult to ensure the edge compaction, which leads to the cracking of the base layer and the formation of early damage, which affects the performance of the pavement
