Abstract
The utility model relates to a rubble basic unit is stabilized to green type, including the subbase and up basic unit, asphalt concrete pavement lower surface course, the asphalt concrete pavement upper surface course of laying in proper order, the subbase is cement stabilized rubble compounding subbase, and the basic unit is that the industrial waste residue stabilizes rubble mixture basic unit asphalt concrete pavement upper surface course is the cold LB-13 layers of cold-mixed cold-paving of fine grain formula bituminous mixture, and asphalt concrete pavement lower surface course is for the hot AC-25 layers of regenerating of coarse grain formula bituminous mixture plantmix. The utility model discloses the environmental protection characteristics of full play each layer reduce and delay the production and the development of road surface transmission crackle, improve the old and useless material utilization ratio and reach more than 80%, solve simultaneously because of the old material piles up the land resource waste and the environmental pollution problem that cause.
Description
Technical Field
The utility model belongs to the technical field of road engineering, concretely relates to rubble basic unit pavement structure is stabilized to green type cement.
Background
The semi-rigid base layer has the advantages of high strength, high bearing capacity, good integrity, strong fatigue resistance, good water stability and the like, so the semi-rigid base layer is widely applied to highway construction in China, wherein cement stabilized macadam is one of main application types. The conventional common cement stabilized macadam base is composed of cement, macadam and water (wherein the cement mixing amount is 3-6% by weight of the macadam, the water consumption is 4.5-6.0% by weight of the macadam and 100% by weight of the macadam, the cement stabilized macadam base has the defects of shrinkage cracking, water damage, high manufacturing cost and the like in the use process, and meanwhile, cement serving as a cementing material of the cement stabilized macadam base is a high-energy-consumption material and has a great influence on the environment in the production process.
Disclosure of Invention
In order to solve the problem, the utility model provides a rubble road surface basic unit pavement structure is stabilized to green type practices thrift a large amount of limited resources, effectively improves the utilization ratio of old and useless material, reduces construction cost, has important meaning to realizing "green highway" construction and national energy saving and emission reduction target.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the utility model relates to a rubble basic unit is stabilized to green type, including subbase and the basic unit of up laying in proper order, asphalt concrete pavement lower surface course, asphalt concrete pavement upper surface course, its characterized in that: the subbase layer is a cement-stabilized macadam mixture subbase layer, the base layer is an industrial waste residue-stabilized macadam mixture base layer, the upper surface layer of the asphalt concrete pavement is a fine-grain asphalt mixture cold-mixing cold-paving LB-13 layer, and the lower surface layer of the asphalt concrete pavement is a coarse-grain asphalt mixture plant-mixing hot-recycling AC-25 layer.
The utility model discloses a further improvement lies in: the thickness of the cement stabilized macadam mixture subbase layer is 20-22 cm.
The utility model discloses a further improvement lies in: the thickness of the industrial waste residue stabilized macadam base is 18-20 cm.
The utility model discloses a further improvement lies in: the thickness of the upper surface layer of the asphalt concrete pavement and the thickness of the lower surface layer of the asphalt concrete pavement are combined to be 12-16 cm.
