How to fix a pothole without spending too much $$$
Concrete pothole repair open to traffic immediately
-- Henan Huineng SC type concrete repair material help you!
Pls see below case:
Date: 29th Sept. 2014
Add: S308 segment road Harbin yilan county
Site situation:Construction site is concrete road pavement,which is uneven,and have many potholes.
Construction area:4000㎡
Effect client wanted: smooth surface,strong adhesion,uniform color
Construction Scheme:
For pothole, suggest use SC type concrete repair material.
Repair process as follows:
Identifying→Marking out→Joint-cutting→Chiseling→Washing→Mixing material→
Repairing→Joint-cutting→Curing→Open to traffic
We follow observation to repaired effect after restore traffic.
Initially achieved expected effects,Results as follows:
1)1 hour restore traffic,reduce traffic pressure,effectively prevent the happening of
accident.
2)High adhesion strength with original concrete.
3)High compressive flexural strength.
4)Without drying shrinkage joint in repair combining area.
5)Uniform color with original concrete
6)Expansion shrinkage coefficient is basically same.
Why SC concrete repair can repair so beatuiful?
1.pls see test data of 28 days
Test items | Unit | Technical requirement | Test result | Individual conclusion | |
Setting time | Initial setting | Min | ≥20 | 25 | Meet requirement |
Final setting | ≤60 | 35 | |||
Compressive strength | 4h | Mpa | ≥20 | 33.0 | Meet requirement |
1d | ≥40 | 66.1 | |||
28d | ≥50 | 90.5 | |||
Pull strength | 28d | Mpa | ≥2.0 | 2.8 | Meet requirement |
Expansion rate | 28d | / | 0.00%-0.1% | 0.01% | Meet requirement |
2.SC concrete repair material 6 big advantage:
1)Rapid repair, 1 hour open to traffic
2)Good adhesion,Compressive & Flexural strength is 2 times of normal concrete.
3)Toughness & impact resistance strength is 5-8 times of normal concrete.
4)Frost resistant & sulphate corrosion resistant, non- toxic, non-corrosive.
5)Beautiful,uniform color,Expansion shrinkage coefficient is basically same with grass-roots concrete.
6)Simple & rapid construction,Can be used as first-aid repair materials in damp environment.
3.Benefit analysis:
SC type cement road repair material have super strong compressive strength, adhesion strength and durability. Rapid,efficient repair to disease area.after completed repair, 1 h can open to traffic.
Compared with cement road paving asphalt, this method have 4 big advantage:
1)Can save some money of repairing in earlier stage.
2)Repair service life is long
3)Road bearing capacity is high
4)Adhesion force is far more than asphalt, save time and labour in later period maintenance,
don't need repair again and again.
