The highway construction usually adopts cement stabilized macadam semi-rigid base course + two-layer asphalt pavement, and the semi-rigid pavement has the advantages of strong structural bearing capacity, strong load transfer capacity, low manufacturing cost and the like, but some early damages such as cracks, pits, grout turning, peeling and the like occur due to overload, bad weather, quality control and the like. The highway construction usually adopts two-layer asphalt pavement with a cement-stabilized macadam semi-rigid base layer and about +10cm, the semi-rigid pavement has the advantages of strong structural bearing capacity, strong load transfer capacity, low manufacturing cost and the like, but some early damages such as cracks, pits, grout turning, peeling and the like appear due to overload, severe weather, quality control and the like.
Aiming at the problems of more cracks of the road surface layer, falling of an asphalt film and the like at present, preventive maintenance measures are needed to be taken in the using process. The sealing technology is that a cementing material or a mixture formed by mixing the cementing material and aggregates with a certain proportion is spread on the original asphalt pavement, so as to form a sealing layer. The sealing layer is divided into a fog sealing layer, a cold-mixed cold-laid sealing layer and a gravel sealing layer, but the materials of the sealing layer which is better used in China at present are mostly finished products imported from Europe and America, and the price is high. In recent years, composite seal layers are adopted successively, but the existing composite seal layers still have the problems of poor repairing effect, easy peeling, short service life and the like.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sealing is synthesized to non-disturbance type suitable for restoration punishment road surface disease.
Realize the utility model discloses the technical solution of purpose does: a non-disturbance type comprehensive seal layer suitable for repairing and treating pavement diseases comprises a high-permeability reduction regeneration seal layer, a rubber asphalt macadam seal layer and a fiber micro-surfacing part which are arranged on a semi-rigid pavement from bottom to top.
Further, the high-permeability reduction regeneration seal layer comprises emulsion stock solution KRS, quaternary ammonium salt QAS, nonylphenol polyoxyethylene ether OP, penetrating agent JFC and water.
