Abstract
The utility model relates to arrive a kind of bituminous pavement with self-repair function.The bituminous pavement is with a thickness of 3-20cm, including pitch main body, multiple self-repairing microcapsules and multiple chopped strands；Multiple self-repairing microcapsules are in the wavy distribution of pitch main body Nei Yan road length direction；Multiple chopped strands are in the wavy distribution of pitch main body Nei Yan road length direction, and the wavy concave and convex direction that self-repairing microcapsule is formed is opposite.Compared with prior art, the utility model using blend modified asphalt than it is unmodified when have preferably elasticity and toughness, and pitch be on active service during generate micro-crack when, chopped strand first controls crackle, its further expansion is prevented, meanwhile, crackle stimulates effect microcapsule wall to rupture, release renovation agent therein, into crack, reparation behavior occurs, repairs pitch micro-crack, improve asphalt performance, prolongs its service life；It is simple with formula, facilitate preparation, high-efficient, the apparent advantage of effect.
Description
Technical field
The utility model belongs to technical field of road engineering, it particularly relates to arrive a kind of drip with self-repair function
Green road surface.
Background technique
" interface " that bituminous pavement is directly related with driving as road has special heavy in entire pavement structure
The meaning wanted.In the long-term use process of bituminous pavement, the test of various complex environments is undergone at structure, it is some small
Cracking and local damage can be generated inevitably, cannot such as control these micro-damages in time, these micro-cracks will be in outside
Cracking is extended under the action of load, and then will affect the service life of pavement structure, structure heavy then that entire road can be destroyed.Institute
With how timely and effectively to repair the crackle occurred in road surface and damage becomes mainly asking for road worker care
Topic.Pitch itself has certain self-healing capability, but closely related with the time of locating temperature, reparation, in practical application
Seldom there is long-time hot stage and self-healing occurs for it.Therefore, it is necessary to seek a kind of new technology, to inside asphalt pavement
The crackle of appearance and damage can be perceived in time and actively be repaired, its self-healing capability be promoted, to extend road surface service life.
Self-repairing microcapsule is a kind of selfreparing means carried out with substance supply mode.Take the hand of cyst wall cladding capsule-core
Section generates stimulation to microcapsules when material generates micro-crack, and cyst wall rupture releases core materials, and core materials encounter point
The catalyst being dispersed in system, reacts at micro-crack, improves substrate performance, delays material damage, extends material lifetime.
Due to microcapsules selfreparing have many advantages, such as applicability wide, mature preparation process, substrate performance is influenced it is small, the concern being subject to
It studies the most extensive.In addition, current self-repairing microcapsule is easy to be stimulated in construction releases core materials in advance, this
Just scattered and disappeared its original function.
Summary of the invention
In order to solve prior art problem, the utility model provides a kind of high-performance and the pitch with self-repair function
Road surface.
A kind of bituminous pavement with self-repair function described in the utility model, the bituminous pavement is with a thickness of 3-
20cm, including pitch main body 1, multiple self-repairing microcapsules 2 and multiple chopped strands 3；Multiple self-repairing microcapsules 2 are dripping
The green 1 wavy distribution of the road Nei Yan length direction of main body；Multiple chopped strands 3 are wavy in 1 road Nei Yan length direction of pitch main body
Distribution, and the wavy concave and convex direction that self-repairing microcapsule 2 is formed is opposite；The appearance coating one of the self-repairing microcapsule 2
Layer streptomyces hygroscopicus polysaccharide.
Bituminous pavement described in the utility model with self-repair function, pitch used in pitch main body 1 are commercially available
70#, 90# and all kinds of modified pitch.
Bituminous pavement described in the utility model with self-repair function, the self-repairing microcapsule 2 include cyst wall 21
With capsule-core 22.
Bituminous pavement described in the utility model with self-repair function, the cyst wall 21 are epoxy resin, Mi Quanshu
Rouge or Lauxite.
Bituminous pavement described in the utility model with self-repair function, the capsule-core 22 are made of all kinds of renovation agents,
Including all kinds of commercially available bitumen regenerants, epoxy resin, epoxy acrylic resin or polyurethane resin.
Bituminous pavement described in the utility model with self-repair function, 2 partial size of self-repairing microcapsule are 1-900
μm。
Bituminous pavement described in the utility model with self-repair function, 3 length of chopped strand be 0.5cm~
3cm。
Bituminous pavement described in the utility model with self-repair function, the chopped strand 3 is by polyester fiber, mineral
Fiber or carbon fiber are made.
Compared with prior art, the bituminous pavement described in the utility model with self-repair function, using blending and modifying
Pitch than it is unmodified when have preferably elasticity and toughness, and pitch be on active service during generate micro-crack when, chopped strand
Crackle is controlled first, prevents its further expansion, meanwhile, crackle stimulates effect microcapsule wall to rupture, and releases therein
Renovation agent occurs reparation behavior, repairs pitch micro-crack into crack, improves asphalt performance, extends it and uses the longevity
Life；It is simple with formula, facilitate preparation, high-efficient, the apparent advantage of effect；In addition, streptomyces hygroscopicus polysaccharide is polysaccharide object
The shell of matter, formation has elasticity, when self-repairing microcapsule is squeezed, can be used as buffering and is unlikely to rupture in advance, when
After being coated in the self-repairing microcapsule embedment bituminous pavement of streptomyces hygroscopicus polysaccharide, with the infiltration of water on road surface, absorb water strepto-
Granulose slowly dissolves, can be gradually by releasing self-repairing microcapsule；Streptomyces hygroscopicus polysaccharide has antibiotic property, also favorably has it to deposit
It puts.
Detailed description of the invention
Fig. 1 is the bituminous pavement top view with self-repair function.1- pitch main body；2- self-repairing microcapsule；The micro- glue of 21-
Capsule cyst wall；22- microcapsules capsule-core；3- chopped strand.
