Abstract

The invention relates to the technical field of pavement construction, in particular to a high-performance ultra-thin asphalt wearing layer and a paving method thereof.The ultra-thin asphalt wearing layer comprises a waterproof bonding layer arranged on an original pavement and a surface wearing layer arranged on the waterproof bonding layer; the surface wearing layer is prepared from the following components in parts by weight: 84-90 parts of aggregate, 5-8 parts of modified asphalt, 3-8 parts of mineral powder and 0.1-0.5 part of polyester fiber; the ultra-thin asphalt wearing layer provided by the invention is used for pavement maintenance, and due to the adoption of the special binding material, the pavement has ultra-strong interlayer bonding performance, anti-aging performance, reflection crack resistance and low-temperature cracking resistance, and also has good construction workability, so that the wearing layer has thinner structural thickness.

Description

technical field

[0001] The invention relates to the technical field of pavement construction, in particular to a high-performance ultra-thin asphalt wear layer and a paving method thereof. Background technique

[0002] At present, when the highway management department selects the early and mid-term maintenance measures for asphalt pavement, technologies such as zero-sealing layer, micro-surface and gravel-sealing layer are mainly adopted. Practice has shown that the above-mentioned existing technologies can improve the traffic capacity and service level of the existing pavement to a certain extent, but there are still insufficient durability, high road noise, easy peeling, large milling workload and low construction efficiency. There are technical defects such as large road traffic interference.

[0003] As a refined, low-carbon and environmentally friendly road pre-maintenance technology, ultra-thin asphalt overlay has been widely used at home and abroad. This technology...
