Problems solved by technology

The disadvantage of the existing technology is that it cannot prevent water seepage. The cohesive force (adhesion) between the original fog seal layer and the original pavement stone cannot achieve the expected effect, and it will fall off after a period of time in traffic, exposing the original The surface of the stone, so it cannot play the role of anti-slip

Embodiment Construction

[0027] Such as figure 1 As shown, the anti-skid and anti-seepage fog sealing process, it specifically includes the following steps:

[0028] step 1:

[0029] 1) The construction section is closed, cleaned, and blown. In order to ensure the construction quality of the fog seal layer, the construction of the fog seal layer must ensure that the road surface is clean, and the loose stones, dirt, dust, and debris on the original road surface must be thoroughly cleaned. It can be washed with a road sweeper or water, but it must be noted that the water washing must be completed 24 hours before, and the road surface must be dry during construction.

[0030] 2) Material preparation and equipment debugging;

[0031] The materials are prepared as follows:

[0032] a) Selected material: base asphalt: 70 ＃ or 90 ＃ Grade A road petroleum asphalt (here is 90 ＃ Grade A road petroleum asphalt); emulsifier: cationic emulsifier; modifier: latex; anti-reflection agent: alcohol anti-reflect...

Abstract

The invention relates to an antiskid and anti-seepage fog sealing layer technology which comprises the following steps of: 1, preparing for construction, namely 1) closing, cleaning and sweeping a construction road, 2) preparing materials and debugging equipment, and 3) detecting technical indexes; 2, debugging and spreading fog sealing layer machinery; 3, performing maintenance; 4, performing detection; 5, opening the traffic. The antiskid and anti-seepage fog sealing layer technology is characterized in that the material preparation in the step 1 comprises the following substeps of: a) selecting the following materials, namely 70# or 90# level-A road petroleum asphalt serving as matrix asphalt, a cation emulsifier, latex serving as a modifier, and an alcohol type anti-reflection agent; b) mixing modified emulsified asphalt, namely mixing the matrix asphalt, the emulsifier, water, the anti-reflection agent and the modifier according to the mass proportion of 482 to 18 to 500 to 1.6 to 4.4. According to the antiskid and anti-seepage fog sealing layer technology, severe damages of degranulation, water seepage and the like which are caused by long-time wheel heavy-duty traffic on the old pavement are effectively avoided; a good seepage prevention effect is achieved, and the antiskid effect of the pavement is enhanced at the same time.

Description

technical field [0001] The invention relates to the field of road construction, in particular to an anti-skid and anti-seepage fog sealing layer technology. Background technique [0002] Fog seal construction technology is one of the important means of preventive maintenance of asphalt concrete pavement developed and gradually matured in recent years. After the original asphalt pavement has been subjected to long-term natural factors (wind, rain, ultraviolet rays, etc.) and driving action, the pavement binder will age and lose seriously, the bonding effect will decrease, the surface aggregate will loosen and fall off, or the porosity in the surface layer will be too large In the case of severe water seepage, special modified emulsified asphalt is sprayed with a certain concentration on the surface of the original road surface through special spraying equipment. In order to supplement the pavement surface binder, fill the gaps in the surface layer, enhance cohesion and effec...
