Problems solved by technology

[0004] In the above technical solution, only a simple sand-mist sealing layer treatment is carried out on the paved road surface, and spraying materials with different ratios are not used for different road surface conditions, and of course the number of spraying layers is not determined according to the road surface conditions. , for the processing of high-demand road surfaces, the above method cannot completely solve complex road surface problems

Embodiment 1

[0048] A construction method for a sand-mist seal in road maintenance provided in this embodiment comprises the following steps:

[0049] S1. Enter the road section to be maintained, and re-distribute the lanes on the road section to be maintained. According to the road conditions, it can be completely closed, or a diversion lane can be reserved to control road traffic to avoid coating or coating. When the layer is not dry, the vehicle enters the repair section.

[0050]S2. Test the water seepage coefficient, friction coefficient, and structure depth of the road section to be maintained, determine the exact ratio of raw materials for the seal layer containing sand and mist according to the water seepage coefficient, friction coefficient, and structure depth of the above test, and prepare the spray according to the above ratio liquid; the details are as follows: the proportioning range of raw materials by volume for the spray liquid is:

Embodiment 2

[0078] The construction method of a kind of fine anti-skid sealing layer of the present embodiment, it differs from embodiment one in that;

[0079] S2. Test the water seepage coefficient, friction coefficient, and structure depth of the road section to be maintained, determine the exact ratio of raw materials for the seal layer containing sand and mist according to the water seepage coefficient, friction coefficient, and structure depth of the above test, and prepare the spray according to the above ratio liquid; the details are as follows: the proportioning range of raw materials by volume for the spray liquid is:

[0080] MasterSeal Concentrate Coverstock 100L

[0081] water 25L

[0082] TopTuff Polymer Additive 4L;

[0083] According to the ratio of raw materials by volume of the above-mentioned spraying liquid, the amount of fine sand added in step S6 is 50 kg. The details are as follows

[0084]

[0085] Through the test and comparison of the pavement conditions b...

Abstract

The invention relates to the technical field of road maintenance, and particularly discloses a construction method of a sand-containing fog sealing layer in road maintenance. The method comprises thefollowing steps: S1, entering a to-be-maintained road section, and carrying out lane redistribution on the to-be-maintained road section; S2, testing the pavement of the to-be-maintained road section;S3, cleaning the pavement; S4, carrying out traffic facility protection; S5, treating pavement diseases; S6, spraying a sand-containing fog sealing layer; S7, carrying out secondary layer sealing; S8, repairing: repairing and sealing the pavement which is not sprayed by the equipment; S9, removing construction sundries, and removing all tools from the site; and S10, opening traffic. Before pavement repair, various coefficients of the pavement are measured, the component ratio of a spraying material is determined according to the measured data, the spraying material is mixed into a coating, the coating is sprayed, the number of spray layers is determined according to the measuring structure, and before spraying, diseases of the pavement are treated firstly, then coating sealing treatment is carried out, so the uniformity and stability of the sealing layer are improved.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to a construction method for a sand-mist sealing layer in road maintenance. Background technique [0002] With the development of society, roads have become arteries connecting cities. And if a place or city wants to develop, first of all, road construction must be synchronized with urban development. After the road has been used for a period of time, due to the heavy traffic flow and the rolling of heavy trucks, the road surface will be damaged to varying degrees, so it needs to be repaired and maintained. When there are cracks, potholes, etc. on the road surface, the traditional method It is to carry out renovation on a large scale, and the above method has high cost and construction time, which is unfavorable for urban development and traffic. [0003] In the prior art about the sand mist seal layer, such as Chinese published patents, such as Chinese published patents ...
