Embodiment Construction

[0013] Attached below figure 1 , attached figure 2 The present invention will be further described in detail with specific embodiments, and it should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0014] Such as figure 1 , figure 2 As shown, a basalt asphalt pavement structure includes a cushion layer 5, a base layer and a surface layer, the base layer is a basalt asphalt base layer 3, and the basalt asphalt base layer 3 is connected to each other by several basalt asphalt base structure units to form a network topology , that is to say, the basalt asphalt base structure units are closely arranged and laid one by one. The basalt asphalt base structure unit includes three benzene ring-connected basalt prefabricated blocks 1, the outer layer of the basalt prefabricated block 1 is an asphalt frame 2, and the basalt asphalt base structure unit is made of basalt m...

Abstract

The invention discloses a basalt asphalt pavement structure. The basalt asphalt pavement structure comprises a cushion layer, a base layer and a surface layer; the base layer is a basalt asphalt baselayer, and the basalt asphalt base layer includes a basalt asphalt basement structural unit; the basalt asphalt basement structural unit includes three benzene-ring-connected basalt prefabricated blocks, and the outer layers of the basalt prefabricated blocks are asphalt; and the basalt asphalt basement structural unit are made of basalt melt and asphalt melt through film injection and cooling. Compared with the prior art, basalt and the asphalt are added into the basalt asphalt pavement structure to manufacture the prefabricated blocks to be added to the pavement structure; and since the basalt material is arranged at intervals in the pavement structure, the road performance of the basalt asphalt pavement structure is good, excellent resistance to high temperature deformation and cracks,resistance to rutting and resistance to water damage are possessed, and the durability and anti-fatigue properties of asphalt pavements can be effectively improved and the problems such as road noiseand stress are effectively solved.

Description

technical field [0001] The invention relates to the technical field of highways, in particular to a basalt asphalt pavement structure. Background technique [0002] The pavement not only bears the load of the wheels, but also is affected by natural environmental factors. Due to the influence of traffic load and atmospheric factors on the pavement, it generally weakens gradually with depth, so the pavement is usually a multi-layer structure. Good quality materials are laid on the upper layer with higher stress, and poor quality materials are laid on the lower stress. The lower layer of the subgrade, thus forming a pavement structure that adopts materials of different specifications and requirements on the subgrade, and lays cushion, base and surface layers respectively. [0003] The traffic characteristics of modern asphalt pavement are: high traffic density, axle load, short load gap, high speed and channelization. Cracks in the road surface, etc. Chinese patent CN2012147...
