Description
Technical field
The invention belongs to matting materials technical field, and in particular to a kind of preparation side of asphalt pavement crack patching material
Method.
Background technology
Highway is the long-term exposed banded structure thing in the Nature, and it undergos extremely hot, severe cold, freeze thawing, sleet for a long time
The test of the external environment severe with Exposure to Sunlight etc., and subject the repeat function of the instantaneous dynamic load of driving for increasingly aggravating, pitch
Road surface has generated substantial amounts of early damage.Therefore China most of bituminous paving oneself enter the peak of maintenance
Phase, wherein crack are a kind of topmost damaged forms of bituminous paving.Road surface once occurs in that crack, not only destroys pavement structure
Integrality road-ability and security also greatly reduces.If carrying out not in time is repaired, in the process that vehicle is exercised
In, crack can be subject to impulsive force and the rainwash effect of tire, and crack can continue to develop in length and depth both direction,
Over time with the development in crack, road surface easily forms pit.More seriously, the ponding on road surface can be oozed by crack
Thoroughly to roadbed the inside, the strength and stability of roadbed is on the one hand weakened significantly, pavement destruction is on the other hand caused more by frost heave
Plus it is serious, greatly shorten the service life on road surface.
Oneself enters the peak period of maintenance to most of bituminous paving of China, and wherein crack is main bituminous paving
A kind of damaged form.Road surface once occurs in that crack, not only destroys the integrality of pavement structure, and driving also greatly reduces
Comfortableness and security, shorten the service life on road surface, it is therefore desirable to which fracture is repaired in time.Current patching material,
Deficiency is all there is, it is necessary to research and develop the patching material of new high performance-price ratio in performance and price.
The content of the invention
The technical problem of solution：The purpose of the present invention is to overcome the deficiencies in the prior art and provide a kind of asphalt pavement crack
The preparation method of patching material.
