Problems solved by technology

[0004] At present, the operation requirements of road traffic are getting higher and higher. Once the road surface in the city is damaged, it must be repaired in time. The construction is extremely difficult and will bring pressure to traffic operation.
At the same time, the damage to the road after the disaster will have an impact on the development of rescue work

Embodiment 1

[0040] Example 1: A prefabricated multi-lane road with recycled aggregate from construction waste

[0041] (1) According to the different geological conditions and environment of the construction site, adopt the corresponding roadbed construction method. Make the subgrade meet the design requirements; (see figure 1 )

[0042] (2) Pave construction waste regenerated fine aggregate on the roadbed as the cushion layer (1). The width of the cushion layer (1) is the same as that of the roadbed, and the designed thickness is 150 mm. The loose paving coefficient is determined through experiments during paving. . At the same time meet the urban road construction technology; (see figure 1 )

[0043] (3) Design a corbel (8) every 10000mm on the paved cushion (1). The height of the corbel (8) is the same thickness as that of the base (2), and the width is designed to be 1000mm, and the binding steel mesh is placed at its corresponding place. Simultaneously every 3 to 5 corbel beams...

Abstract

The invention discloses an assembled prestressed construction waste recycled aggregate road and a construction method thereof. The recycled aggregate road comprises a cushion layer, a base layer, a sliding layer and a surface layer, wherein the surface layer is formed by splicing a plurality of precast recycled concrete road slabs with reserved prestressed bar holes, sleeper beams are placed below transverse joints of the precast recycled concrete road slabs, and waterproof rubber strips are embedded in the transverse joints and longitudinal joints; and the precast recycled concrete road slabs at two ends are stretched so as to be connected with the sleeper beams through telescopic components. The road structure manufactured by the construction waste recycled aggregate is convenient and fast in overall manufacturing and high in economic benefit, the carrying capacity of the road structure is enhanced, the deformation performance of the road structure is improved, the ductility of the road structure is increased, and the construction time is greatly shortened. The construction method is suitable for road structures, such as town roads and post-disaster emergency repair roads.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to an assembled prestressed construction waste recycled aggregate road and a construction method thereof. Background technique [0002] Among urban waste, construction waste accounts for 30% to 40% of the total waste. In the future, as urban construction progresses from extensional development to connotative large-scale old city renovation, the amount of construction waste generated in my country will continue to grow. In the face of increasingly severe environmental pollution, increasingly tense land supply, and increasingly depleted mineral resources, a huge amount of construction waste is bound to aggravate the contradiction between people, the environment, and resources, and affect the coordinated development of the urban ecological environment. The comprehensive utilization of construction waste is urgent. [0003] According to statistics, the constructi...
