Embodiment Construction

[0047] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0048] see Figure 1-5d , which shows an embodiment of a lattice sandwich coil according to the invention. The dot-matrix sandwich coil is divided into three layers. From top to bottom, it is geotextile 1 coated with petroleum asphalt, cylindrical rubber particles 2 and geotextile 3 coated with rubber asphalt. The array is arranged between the geotextile 1 coated with petroleum asphalt and the geotextile 3 coated with rubber asphalt, and is in close contact with them. The columnar rubber particles are periodically and regularly arranged between the two layers of geotextiles....

Abstract

The invention relates to a bituminous pavement provided with a lattice structure transition compound layer. The lattice structure transition compound layer is arranged between a semi-rigid base layer (7) and a bituminous concrete surface layer (4) of the bituminous pavement; and the lattice structure transition compound layer comprises a rubber bituminous stress absorption layer (5) and a lattice sandwich coil which is tightly adhered above the rubber bituminous stress absorption layer. The lattice sandwich coil sequentially comprises a piece of geotextile (1) for covering petroleum bitumen, columnar rubber grains (2) and a piece of geotextile (3) covering with rubber bitumen. According to the bituminous pavement disclosed by the invention, the current problems of stacking a plurality of wasted tires and pollutants are solved according to the reduction of the bituminous pavement or the delaying of the generation of reflection cracks, and the environmental friendliness and the resource recycling are integrated. The bituminous pavement can be used for the technical field of road engineering.

Description

technical field [0001] The invention relates to an asphalt pavement with a transition composite layer of a lattice structure and a construction method thereof, which are used to prevent the cracks of the semi-rigid base from being reflected to the asphalt concrete surface layer, and belong to the technical field of road engineering. Background technique [0002] Semi-rigid base has been widely used in the design of flexible pavement base in my country due to its advantages of high strength and stiffness, good water stability, and convenient access to nearby materials. As a result, cracks are inevitable in the semi-rigid base, but the semi-rigid base has poor deformation resistance and is sensitive to changes in temperature and humidity, so it is easy to produce dry shrinkage cracks and thermal shrinkage cracks. Once the semi-rigid base layer is cracked, under the repeated action of traffic load stress and temperature-variable stress on the road surface, stress concentration o...
