Abstract

The invention relates to a water permeable type large-hole cement stabilized macadam pavement base layer material and a preparation method thereof. Raw materials comprise graded gravel, cement and water. The grading range of the graded gravel meets the requirements that 0.075 mm meshes correspond to the mass passing rate from 0% to 3%, 0.6 mm meshes correspond to the mass passing rate from 0%to 6%, 2.36 mm meshes correspond to the mass passing rate from 0% to 12%, 4.75 mm meshes correspond to the mass passing rate from 3% to 18%, 9.5 mm meshes correspond to the mass passing rate from 16% to 36%, 19 mm meshes correspond to the mass passing rate from 60% to 85%, 26.5 mm meshes correspond to the mass passing rate from 80% to 100%, 31.5 mm meshes correspond to the mass passing rate of 100%, the flat and elongated particle content is smaller than or equal to 18%, and the crushing value is smaller than or equal to 22%. The preparation method is simple, the grading composition range of the graded gravel is improved, under the condition that the bearing force of the graded gravel is guaranteed, the porosity of the structure is increased, on one hand, the water drainage performance of a pavement is improved, on the other hand, the reflection cracks of the asphalt concrete pavement are reduced, the maintenance cost of the pavement is reduced, and social and economic benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of pavement base material design, and relates to a permeable large-pore cement-stabilized gravel pavement base material and a preparation method for sponge city construction. Background technique [0002] In recent years, with the rapid development of urbanization in my country, urban development is also facing huge environmental and resource pressures. The urban development model of extension growth has become unsustainable. my country's urbanization must enter a new stage of transformation and development that focuses on improving quality. stage. Therefore, we must adhere to the development path of new urbanization and coordinate the contradiction between urbanization and environmental resource protection in order to achieve sustainable development. The report of the 18th National Congress of the Communist Party of China clearly stated that "in the face of the severe situation of tightening resource co...
