Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the schematic embodiments and descriptions are only used to explain the present invention, but are not intended to limit the present invention.

[0037] A kind of highly viscoelastic modified rubber asphalt pavement and construction technology thereof described in this specific embodiment, its asphalt pavement comprises base layer 1, and base layer 1 is laid with waterproof composite geogrid, and waterproof composite geogrid is poured with modified emulsification asphalt to form an asphalt lower layer 2; the asphalt rubber layer 3 of 6 cm is laid on the asphalt lower layer 2, and a modified emulsified asphalt adhesive layer 4 is laid on the rubber asphalt layer 3, and a 4 cm high layer is laid on the modified emulsified asphalt adhesive layer 4. The viscoelastic modified rubber asphalt 5 forms the main pavement layer 6; the left and righ...

Abstract

The invention relates to the technical field of pavement construction, in particular to a high-viscoelastic modified rubber asphalt pavement and a construction process thereof. The high-viscoelastic modified rubber asphalt pavement comprises a base course; a waterproof composite geogrid is laid on the base course, modified emulsified asphalt is poured to the waterproof composite geogrid to form anasphalt lower course; a 6 cm rubber asphalt course is laid on the asphalt lower course; a modified emulsified asphalt adhesive course is laid on the rubber asphalt course; 4cm high-viscoelastic modified rubber asphalt is laid on the modified emulsified asphalt adhesive course to form a pavement main course; flat stone courses are correspondingly arranged on the two sides of the pavement main course; and side stone courses are arranged on the left and right sides of the flat stone courses. The high-viscoelastic modified rubber asphalt pavement has the advantages that the viscosity is higher, the content of a cementing material is high, and the resisting ability of the pavement to the occurrence of cracks, fatigue cracks and reflection cracks is improved; by using a composite modified rubber asphalt technology, the temperature sensibility is reduced, the rut resistance and permanent deformation resistance of the pavement are enhanced; the maintenance cost of the pavement is obviously lowered and so on.

Description

technical field [0001] The invention relates to the technical field of pavement construction, in particular to a high-viscoelastic modified rubber asphalt pavement and a construction process thereof. Background technique [0002] With the increase of road construction sections in our country and the rapid economic development, it also leads to the increase of the pressure load on the road surface and the damage of the road surface. The traditional asphalt pavement refers to the pavement with asphalt concrete as the surface layer. It is a mixture made by artificially selecting mineral materials with a certain gradation composition (crushed stone or crushed gravel, stone chips or sand, mineral powder, etc.) and a certain proportion of road asphalt materials under strictly controlled conditions. . Asphalt concrete can be divided into petroleum asphalt and coal asphalt according to the different binders used; some countries or regions also use or mix natural asphalt. Accordin...
