Embodiment 1

[0055] This example provides a recycled water stabilizer prepared by using waste earth and stone, including the following components by mass: 96 parts of waste earth and stone and 4 parts of the above-mentioned high-performance inorganic polymer cementitious material;

[0056] Wherein, the high-performance inorganic polymer cementitious material comprises the component of following mass parts: 110 parts of cement and 2 parts of composite admixtures;

[0057] Among them, the composite admixture includes the following components by mass: 30 parts of polycarboxylate superplasticizer, 3 parts of potassium dihydrogen phosphate, 3 parts of sodium lauryl sulfate, 7 parts of modified rice husk ash, 2 parts of viscosity modifier parts and 35 parts of water;

[0058] The viscosity regulator is composed of latex powder and cellulose-based thickener in a ratio of 2:1 in parts by mass;

[0059] Modified rice husk ash is prepared by the following methods:

[0060] Step (1): adding rice hu...

Embodiment 2

[0073] This example provides a regenerated water stabilizer prepared by using waste earthwork and its construction method. The only difference from Example 1 is that the regenerated water stabilizer includes the following components by mass: 93 parts of waste earthwork and high-performance inorganic polymer gelling 3 parts of materials; among them, the high-performance inorganic polymer cementitious material includes the following components by mass: 100 parts of cement and 1 part of composite admixture; the rest of the steps and parameters are the same.

Abstract

The invention discloses a recycled water stabilizing material prepared from waste earthwork and a construction method of the recycled water stabilizing material, and belongs to the technical field of water stabilizing layer materials for road bases and road construction methods. The method mainly comprises the following steps: mixing waste earthwork as a main body with a high-performance inorganic polymer cementing material to prepare a waste earthwork reclaimed water stabilizing material, paving the waste earthwork reclaimed water stabilizing material on a roadbed, and rolling and forming to replace a base layer or a subbase layer of traditional graded broken stone. The road water stable layer implemented by the method has the advantages of high strength, good stability, good durability, strong freezing resistance, low cost and the like, and can shorten the engineering construction period, ensure the engineering quality, improve the structural performance of a highway subgrade and prolong the service cycle of a road; and the problems of high building material cost, high energy consumption, high later maintenance cost and the like in a conventional cement-stabilized layer construction method are solved.

Description

technical field [0001] The invention relates to the technical field of water-stabilized layer materials for road bases and road construction methods, in particular to a regenerated water-stabilized material prepared from waste earthwork and a construction method thereof. Background technique [0002] Construction waste refers to the spoils, spoils, dregs, residual mud and other waste left over from the laying, construction or demolition of various buildings and structures by individuals, construction units or construction units. The output of construction waste in my country is increasing year by year. The composition of construction waste is complex, and the composition of waste produced by buildings of different ages and structures is also different. In March 2021, the National Development and Reform Commission and nine departments jointly issued a document on the comprehensive utilization of bulk solid waste, clearly stipulating that by 2025, the comprehensive utilization...
