Embodiment 2

[0052] Such as figure 2 As shown, a green, low-carbon and environment-friendly road structure using recycled materials includes subgrade and pavement arranged in sequence from bottom to top. The subgrade includes embankment 1 and roadbed 2 arranged in sequence from bottom to top. The road bed 2 is made of urban construction waste recycled graded mixture; the road surface includes a cushion layer 3, a subbase layer 4, a base layer 5, a lower layer 6, and a middle surface layer arranged in sequence from bottom to top 7 and the upper layer 8, the cushion layer 3 is made of recycled construction waste graded aggregate; the subbase layer 4 and the base layer 5 are cement-stabilized inorganic binders composed of 0% to 50% urban construction waste recycled aggregate Or it is made of emulsified asphalt cold recycled mixture composed of old asphalt mixture. The surface layer 7 is made of warm-mix asphalt mixture or hot recycled asphalt mixture with an amount of 0%-40% old asphalt mix...

Abstract

The invention discloses a green low-carbon environment-friendly road structure adopting regenerative material. The structure comprises a subgrade and a pavement which are sequentially arranged from bottom to top; the subgrade comprises an embankment and a road bed which are sequentially arranged from bottom to top, wherein the embankment is prepared from urban building waste regenerative mixture,and the road bed is prepared from urban building waste regenerative grading mixture; and the pavement comprises a cushion layer, a bottom base layer, a base layer, a lower layer, a middle layer and anupper layer which are sequentially arranged from bottom to top, and the cushion layer is prepared from building waste regenerative grading aggregate. According to the structure, the requirements of the existing traffic development can be guaranteed, the environmental problems left due to the urban development are resolved, and the problem of destructive mining on natural resources due to the foundation engineering construction is solved.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a green, low-carbon and environment-friendly road structure that adopts urban construction waste and old asphalt mixture to be regenerated. Background technique [0002] With the acceleration of my country's urbanization process, large-scale old city reconstruction is actively promoted, and a large number of waste buildings have been demolished. my country's annual construction waste is about 3.5 billion tons, and urban demolition and construction waste accounts for 43%, about 1.5 billion tons. However, the recycling rate of construction waste is less than 5%, which is far lower than 70%-98% in developed countries and regions. How to dispose of construction waste has become one of the problems faced by major cities in my country. [0003] At the same time, my country's highway construction has also developed rapidly. However, the energy consumption of highway construction is an ex...
