Abstract
The invention relates to an anti-slide fog seal material and its construction method. The anti-slide fog seal material is obtained by the following steps of: mixing 15-30 parts by weight of composite kaolin, 35-70 parts by weight of water and 1.2-2.0 parts by weight of an asphalt emulsifier, adjusting the pH value into a range required by the corresponding asphalt emulsifier with a pH value conditioning agent, then emulsifying 25-40 parts by weight of hot melt asphalt so as to obtain a stable mixed emulsion, and finally mixing the emulsion with 50-80 parts by weight of sand and conducting stirring. When the anti-slide fog seal material is sprayed on a road surface uniformly by a spraying vehicle, it can bond well with the road surface. Thus, the material not only seals original road surface micro-cracks and voids, plays a strong waterproof role, but also prolongs the road service life. And the sand in the anti-slide fog seal material can substantially improve the anti-slide performance of the road surface.
Description
Technical field
The present invention relates to technical field of highway maintenance technology, be specifically related to a kind of antiskid mist sealing material and constructional method thereof.
Background technology
Mist seal AEMA (Asphalt Emulsion Manufacturers Association) technology is a kind of have efficient maintenance performance, road preventive maintenance with low cost technology.It is directly to spray the mist sealing material at road surface, and the surface of a black promptly is provided for road; It can the shutoff fine cracks and the hole, hole, and stops moisture to get into the surface pore, improves the water resistance on surface; Ability renewal or reduction surfaces be aged pitch, prolongs the work-ing life on road surface; In addition, the aggregate that the firm road surface of mist seal is loose, further loose to prevent it, can protect or the bond of redeck because of wearing out and being lost, reduce aging and weathering road pavement Effect on Performance.
More mist sealing material is arranged at present both at home and abroad; Yet find in the practical engineering application; The defective of two broad aspect below they in use all exist: (1) construction initial stage cling property is not enough, can form one deck asphalt membrane, the asphalt film smooth surface that this layer is made up of free pitch on the road surface after the construction of mist seal; And the frictional force between the tire is little, has directly reduced the cling property on road surface.(2) wear resisting property and relatively poor with the adhesion property on road surface, i.e. poor durability, common mist seal is using one to after two months, and the mist sealing material on the building stones is ground off, takes away by driving mostly, and the road surface does not observe the vestige that carried out the construction of mist seal basically.
