Problems solved by technology

Although these technologies can meet the basic functional requirements, they have defects to varying degrees: the sand mist seal layer has weak functions, and only has the function of sealing water and beautifying the road surface; The gravel seal layer is noisy and easy to produce flying stones, which affects driving safety; the cost of Novachip ultra-thin wear layer and epoxy coating is high, and the sealing construction time is long, which affects traffic and other issues

Embodiment 1

[0019] Using 20 parts of modified emulsified asphalt as bonding material, together with 2 parts of interlayer interface agent, 50 parts of anti-skid and noise reduction material and 3 parts of surface protection agent, construction method:

[0020] (1) Traffic closure: conduct traffic control according to the determined traffic closure plan;

[0021] (2) Disposal of local diseases on the original road surface: filling joints, repairing potholes, etc.;

[0022] (3) Road cleaning: cleaning road dust, mud and other sundries;

[0023] (4) Construction of low-noise and anti-skid over-surface: special construction vehicles carry out "interlayer interface agent→modified emulsified asphalt→noise-reducing and anti-skid material→modified emulsified asphalt→surface protective agent" synchronously or asynchronously multi-layer in the above order construction;

[0024] (5) After the surface is dry, use a rubber wheel roller to roll 2-8 times;

[0025] (6) Traffic is open after the regim...

Embodiment 2

[0027] 10 parts of modified emulsified asphalt is used as the bonding material, together with 2 parts of interlayer interface agent, 20 parts of anti-skid and noise reduction material and 4 parts of surface protection agent. The construction method is the same as that of Example 1.

Embodiment 3

[0029] 12 parts of modified emulsified asphalt is used as the bonding material, together with 2 parts of interlayer interface agent, 30 parts of anti-skid and noise reduction material and 3 parts of surface protection agent. The construction method is the same as that of Example 1.

Abstract

The invention relates to the technical field of road surface maintenance thin overlay, in particular to a surface treatment method for achieving low noise and skid resistance of a road. The surface treatment method adopts the road as a construction object and is characterized in that a construction vehicle is adopted for sequentially and synchronously spraying an interlayer interface agent, modified emulsified asphalt, a skid resistance and noise reduction material, modified emulsified asphalt and a surface protecting agent on the road surface, so that an ultrathin overlay structural layer with the thickness being 2-9 mm is formed on the road surface. The durability, water sealing performance and skid resistance are better than those of sand containing fog sealing layers and micro-surfacing, the travelling vehicle noise is lower than the micro-surfacing and a macadam sealing layer, the problems that rolling stone is likely to appear on a macadam sealing layer, so that travelling safety is affected, and sheet disengagement is likely to appear in the prior art are solved, and the surface treatment method is the ultrathin surface treatment technology with rapid construction and high cost performance.

Description

(1) Technical field [0001] The invention relates to the technical field of pavement maintenance thin-layer overlays, in particular to a low-noise, anti-skid surface treatment method for pavement. (2) Background technology [0002] Technical requirements for ultra-thin pavement surface treatment: At present, new domestic road construction projects are slowing down, most roads are in the maintenance stage and cement pavement needs to be changed from white to black. [0003] At present, the commonly used ultra-thin surface treatment technologies include: sand mist seal, slurry seal, micro-surfacing, gravel seal, Novachip ultra-thin wear layer, epoxy coating, etc. Although these technologies can meet the basic functional requirements, they have defects to varying degrees: the sand mist seal layer has weak functions, and only has the function of sealing water and beautifying the road surface; The gravel seal layer is noisy, easily produces flying stones, and affects driving safe...
