Problems solved by technology

However, the resource utilization rate of construction waste in my country is less than 5%, and the comprehensive recycling of various construction waste is even less
Most of the construction waste is disposed of or landfilled, which not only seriously pollutes the environment, but also causes a great waste of resources.

Embodiment 1

[0052] The pavement structure of a roadway in a certain city is as follows: After the roadbed 100 is treated, a 32cm thick cement-stabilized muck subbase (7-day unconfined compressive strength is 1.5-2.5MPa) is successively laid on the roadbed 100, and a 18cm-thick Cement-stabilized recycled aggregate base (7-day unconfined compressive strength is 3.0-4.0MPa), pave 12cm thick foamed asphalt cold recycled mixture, spray permeable oil, lay 8cm thick foamed asphalt warm recycled mixture under layer, lay 4cm thick foam asphalt warm mix rubber asphalt mixture top layer.

[0053] 1 Cement-stabilized slag-soil subbase mix design and production construction technology

[0054] 1.1 Cement-stabilized muck subbase mix design

[0055] Take certain technical measures to eliminate the variability of muck. When sampling, use a loader to select samples from different piles and stack them together, and mix them with a shovel continuously. After mixing evenly, select sample materials according...

Abstract

The invention discloses a recycling pavement structure and a pavement building technology thereof and relates to the technical field of road engineering. The recycling pavement structure comprises a roadbed, a base layer and a surface layer. The base layer comprises a cement stabilization muck subbase, a cement stabilization recycled aggregate base layer and a foamed asphalt cold-recycling mixture flexible base layer, all of which are arranged from bottom to top. The surface layer comprises a lower warm mixing recycling asphalt mixture surface layer and an upper warm mixing rubber asphalt mixture surface layer. By the adoption of the recycling pavement structure, a large-scale and high-valued trend can be achieved, the recycling rate of construction waste can reach over 95%, the use rate of recycled aggregate can reach 100%, recycled materials account for 70% to 80% of the whole pavement structure, solid waste such as the construction waste is comprehensively recycled, meanwhile the requirements of related standards are met, energy is saved, emission is reduced, the environment is protected, exploitation and consumption of new building stones can be reduced as well, the construction capital is saved, meanwhile, the recycled aggregate does not need to be degraded for use, the structure is suitable for rainy season construction, and the construction period can be shortened.

Description

technical field [0001] The invention relates to the technical field of road engineering. Background technique [0002] With the acceleration of urbanization, the amount of construction waste generated and discharged is also increasing rapidly. According to statistics, the amount of construction waste produced in the process of urban construction in my country has accounted for 40% of the total amount of urban waste, and it is still increasing year by year. The phenomenon of "garbage siege" has appeared in many places. Construction waste is a kind of solid waste with resourceful properties. After resource disposal, more than 95% of construction waste can be used as raw materials in engineering construction, forming a virtuous circle of sustainable development. In developed countries, the resource utilization rate of construction waste has reached more than 90%. However, the resource utilization rate of construction waste in my country is less than 5%, and the comprehensive ...
