Embodiment Construction
[0029] The following will be combined with Figure 1 to Figure 5 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0030] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on th...

The invention relates to the technical field of highways, in particular to a low-cost long-life asphalt pavement structure based on a novel base material, which comprises a roadbed, a cushion layer arranged at the top of the roadbed, a sub-base layer arranged at the top of the cushion layer, an upper base layer arranged at the top of the sub-base layer, a binding layer arranged at the top of the upper base layer, and an asphalt pavement arranged at the top of the binding layer. A drainage pipe is arranged at the bottom of the asphalt pavement, a drainage groove is formed in the drainage pipe, a water grate is arranged at the top of the drainage pipe, left road shoulders which are evenly distributed are arranged on one side of the asphalt pavement, right road shoulders which are evenly distributed are arranged on the side, away from the left road shoulders, of the asphalt pavement, and the connecting layer and the upper base layer are located between the left road shoulders and the right road shoulders. According to the invention, the coal cinder with lower cost is used as the main component of the pavement subbase, so that the construction cost of the road is reduced, and the subbase is reinforced by the reinforcing agent, so that the subbase of the road is firmer and more durable, and the effects of low cost and long service life of the road are realized.
Description
technical field [0001] The invention relates to the technical field of highways, in particular to a low-cost and long-life asphalt pavement structure based on a novel base material. Background technique [0002] Highways refer to roads connecting cities, between urban and rural areas, between villages and villages, and between industrial and mining bases, which are built in accordance with national technical standards and approved by the competent highway department, including expressways, first-class roads, and second-class roads , third-class roads, and fourth-class roads, but does not include trails naturally formed in fields or rural areas. It is mainly used for automobiles and has certain technical standards and facilities; road reinforcement is a new type of chemical material for the curing of modern road bases and subbases. It is suitable for different soil properties. Under normal temperature, the reinforcement is a black, non-combustible, odorous liquid. It has str...
