Problems solved by technology

[0003] The utilization of construction waste mainly has the following problems: construction waste recycled aggregates are different from traditional aggregates, such as strength, durability, and water stability. Traditional aggregate application methods are not suitable for construction waste recycled aggregates. quality, it may also cause a series of safety problems, so a new construction process is very much needed to ensure the construction quality

Abstract

The invention discloses an application process of construction waste roadbed filling aggregate. The application process comprises the following steps: step 1, selecting raw materials; step 2, preparing a roadbed filling material; step 3, excavating a roadbed;step 4, paving and rolling the roadbed; step 5, laying steel-plastic grating; step 6, performing watering; and step 7, pouring asphalt. The construction waste filling aggregate is used for filling the roadbed, the application problem of the construction waste in roadbed engineering is solved, the utilization rate of the construction waste is increased, a reliable choice is provided for roadbed filling materials and methods, and huge economic benefits and social benefits are brought.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to an application process of construction waste roadbed filling aggregate. Background technique [0002] At present, my country's urbanization process is developing rapidly, and the amount of abandoned construction waste generated by municipal construction, old city renovation and demolition, and cement concrete road reconstruction is increasing day by day. According to statistics, the annual amount of urban construction waste in my country is more than 50 million tons. The main components of construction waste are waste bricks, mortar, concrete, and brick-concrete construction waste. Due to the different components and poor mechanical properties of this type of construction waste, they cannot be directly used as road materials, and because construction waste is not combustible, so Construction waste is disposed of by means of landfilling, stacking, etc. These disposal met...
