Abstract

The disclosure column of the present invention is a green, low-carbon and environment-friendly road structure using recycled materials, including subgrades and road surfaces arranged sequentially from bottom to top, subgrades including embankments and road beds arranged sequentially from bottom to top, and embankments are regenerated from urban construction waste The road bed is made of recycled graded mixture of urban construction waste; the pavement includes a cushion, subbase, base, lower layer, middle surface and upper layer arranged in sequence from bottom to top, and the cushion is made of Made from recycled graded aggregates from construction waste. The invention can not only ensure the needs of the current traffic development, but also solve the environmental problems left over from the urban development and the problems that the basic engineering construction destroys the exploitation of natural resources.

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 recycling of urban construction waste and old asphalt mixture. Background technique [0002] With the acceleration of urbanization in our country, large-scale old city renovation 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 our country. [0003] At the same time, my country's highway construction has also developed rapidly. However, the energy consumption of highway construction is an extensive develo...
