Description
Technical Field
The utility model relates to a road construction technical field, concretely relates to asphalt road's laying structure.
Background
Asphalt pavement refers to various types of pavement that are made by incorporating into mineral materials a road asphalt material. The asphalt binder improves the capability of the paving aggregate to resist damage of traveling vehicles and natural factors to the pavement, and enables the pavement to be smooth, less in dust, impermeable and durable. Accordingly, asphalt pavement is one of the most widely used high-grade pavements in road construction.
At present, with the improvement of domestic environmental protection requirements and the implementation of the latest national resource protection policy, the mining and use of lime (stone or powder) are more and more limited, especially in coastal areas, a large number of limestone mine plants are shut down, and meanwhile, in foreign areas, such as countries like mengla, the yield of limestone is extremely low or none, the limestone (powder) needs to be imported and the cost is high, so that the situation that no limestone (powder) is available on site is gradually met in the conventional lime stabilized soil cushion layer used in the traditional road design and site leveling process, and after the lime stabilized soil cushion layer is subsequently fed back to designers, the replacement material is searched again, so that the construction process is delayed, and the temporary replacement material cannot meet the quality requirement of road pavement.
Disclosure of Invention
The to-be-solved technical problem of the utility model lies in, to the above-mentioned defect of prior art, provide a simple structure, lay convenient and low in cost's asphalt road's laying structure.
The utility model aims at accomplishing through following technical scheme, a laying structure of bituminous paving, include the basic unit of pouring by non-bituminous material and lay the pitch surface course at this basic unit upper surface, the pitch surface course is laid on the basic unit through penetrating the layer, the basic unit includes first basic unit and the second basic unit of laying from bottom to top in proper order, and the thickness of laying of first basic unit and second basic unit is the same, first basic unit is poured by cement, soil, the mixture of broken brick stabilized soil, and the mixing ratio of cement, soil, broken brick stabilized soil is 5:28:67, the second basic unit is poured by 5% cement stabilized macadam.
Further, the asphalt surface layer comprises a medium-grain asphalt mixed soil layer and a fine-grain asphalt mixed soil layer which are laid from bottom to top, the medium-grain asphalt mixed soil layer and the fine-grain asphalt mixed soil layer are connected through a sticky layer, and the laying thickness of the medium-grain asphalt mixed soil layer is larger than that of the fine-grain asphalt mixed soil layer.
Further, the laying thickness of the first base layer and the second base layer is 150mm, the laying thickness of the medium particle type asphalt mixed soil layer is 70mm, and the laying thickness of the fine particle type asphalt mixed soil layer is 50 mm.
The utility model has the advantages of: the utility model discloses simple structure just lays the convenience, replaces lime stabilized soil bed course in the past through the basic unit of pouring by cement, soil, the mixture of broken brick stabilized soil to reduce engineering cost, had characteristics such as rational in infrastructure, long service life, had higher commonality and economic value.
