Description
Technical field
The present invention relates to a kind of pavement patching material and method for repairing road surface, belong to building material technical field.
Background technique
Cement Concrete Pavement Slab block repairs problem, fails to be well solved all the time, one of root problem
Be exactly patching material performance it is undesirable.Material for the repairing of Cement Concrete Pavement Slab block has to comply with following technology and wants
Ask: 1. fast hard high early strong: pavement patching is different from Common Concrete Pavement construction, the concrete road surface for generally needing to repair
All it is mostly road currently in use, does not allow long-time close traffic.Therefore, patching material must have rapid curing property
Can, make to repair the intensity requirement for reaching open to traffic in the short time of road surface.2. shrinking small: Cement Concrete Pavement Reconstruction, the old and new
The binding site of concrete is often most weak link.The one of the major reasons for causing bond between fresh and hardened concretes bad are exactly new
The contraction of mixed concrete.Contraction can generate shrinkage stress, so that New-old concrete be pulled open in weak binding site.Therefore,
Patching material must control shrinking percentage.3. having certain viscosity: the caking property at Yao Tigao bond between fresh and hardened concretes position it is necessary to
Ask patching material itself that there is certain viscosity.4. later period performance is stablized, strength development and old concrete basic synchronization: repairing material
The later strength development speed of material should be almost the same with old concrete, there is not allowed that strength retrogression, but also should not strength development too
Fastly, cause New-old concrete mechanical property difference too big, influence the overall performance on road surface.5. wearability is high, durability is good.6. applying
Work workability is good.
Currently, the patching material for Cement Concrete Pavement Slab block and repair technology research are numerous, and that develops is quick
Patching material is many kinds of, these materials are divided into three according to the application method of fast repairing material both domestic and external and material composition
Kind: quick-hardening cement, fast hardening concrete, quick repairing agent for cement concrete.They pass through the selection of cement type respectively, are added and mix
Solidifying soil admixture and addition concrete admixture achieve the purpose that concrete high-early-strength.It is according to related data studies have shown that existing
The extraordinary patching material that can be used for Cement Concrete Pavement Reconstruction developed mainly include the following types: 1) for Rapid-Repair
Quick-hardening cement, comprising: 1. lumnite cement；2. high alumina cement；3. quick hardening sulphoaluminate, ferrous aluminate cement and fluorine aluminium
Acid salt cement；4. high alumina cement and ordinary portland cement；5. phosphate cement；6. alkali silicon cement.2) Rapid Repair Concrete, comprising:
1. silica-on-silicon optical waveguides；2. metakaolin concrete；3. fibre reinforced concrete and polymer concrete.
CN104045291A discloses a kind of Cement Concrete Pavement Reconstruction material, and the patching material is by percentage to the quality

2.5%~7% redispersable latex powder, 0.08%~1.8% lithium carbonate, 0.7%~1.03% fiber, 0.1%~0.22%
Tartaric acid, 0.02%~0.06% cellulose ether, 26.56%~59.04% quartz sand, 0.08%~0.25% polycarboxylic acids diminishing
Agent, 0.08%~0.33% organic silicon defoamer, 0.2%~0.55% organosilicon moisture repellent.CN104046044A discloses one
Energy saving pavement crack repair material of kind and preparation method thereof, the patching material is excellent containing 3~16wt% of melting temperature depressant
5~15wt% is selected, the softening point of the melting temperature depressant is not less than 110 DEG C, preferably micro- smart wax, alkane paraffin, poly- second
Alkene wax, one of polypropylene wax (APAO wax), the softening point of melting temperature depressant is preferably greater than 115 DEG C or more.
CN102108018A provide it is a kind of using inorganic particle, waste rubber powder modified asphalt as pavement patching material, consisting of: hand over again
700~1200 parts by weight of pitch；Useless 70~150 parts by weight of swelling perlite powder；2~6 parts by weight of activator；Modification infusorial earth
300~700 parts by weight；3.5~8 parts by weight of modified white carbon black；And 1~5 parts by weight of plasticizer.
