Emergency Road Repair Paving Materials : Temping Ascon
Sack Asphalt Concrete
Gilyoung SNC’s emergency road repair paving materials temping asphalt concrete is use to the small area of the construction and paving of the existing emergency and difficult cases of prepare the hot asphalt concrete.By national regulations current KS F 2369 <mixed type bituminous mixture at room temperature for paving. That is a mixture of room temperature aggregate and emulsified asphalt or cutback asphalt mixture>, use for four seasons emergency maintenance.
Characteristics of the loadpatcher
Gilyoung SNC’s road patcher is different of the other products.
It is possible to produce more environmentally friendly products using cutback asphalt (MC) because it does not using oil-based in existing petrochemical.
In addition, it was developed for the prevent of winter's common problem of falling down the fluidity of the sack of asphalt. We are produces high quality sack of road patcher by different configuration of the product according to the season.

Product of Gilyoung SNC
ROADPATCHER, Q-HARD
Gilyoung SNC’s ROADPATCHER Q-HARD is emergency repair material of the road. It is maintain a constant size of aggregate product specifications the basic standards of 3.5-5mm .
This product is harmless to humans because made by eco-friendly material. It is different with the other sack of asphalt of other companies product. The excellent product of workability and curing speed repair have excellent physical properties after open traffic.
SUPERPATCHER
Emergency road repair asphalt superpatcher is
Porthole of emergency road repair asphalt is a region of locally generated, as a way to road repair and construction products, generally the default depth of 50mm or more to repair, the size of the aggregate 3.5-5.0mm is difficult to repair defects in the thin area.
For example, when the depth of the thin area in 2-3mm defects occurred difficult to repair because they are too large aggregate size, with the uniform dimensions of the aggregate size is about 1mm smaller products fits to the construction and maintenance.
Superpetcher is suitable for a field such as uniform products of aggregate, 1mm in size is excellent quality and easy construction.
COLORPATCHER
All road color is a uniform. The road basic color is black, but bus lanes, child protection zone, the color of the roads around the school zone are different. When repair the defective area of the road porthole, House, sidewalk, using the COLORPATCHER
SELFPATCHER
Emergency road maintenance products SELFPATCHER is different to other repair materials. Products by emulsified asphalt binder of different method of bag asphalt.
Without firm the road and paving, only cleaning surface damage part.
The aggregate specification of Gilyoung's SELFPATCHER is producted by filler 3-5mm below.
This products is sales to small individually packing . It is not mixed and the packing is each to each, aggregate, emulsified asphalt, filler.
On the construction site, to do the emulsified asphalt into the aggregate and shake and mixing.
And cleaning for the surface flatness and finish the works.
SELFPATCHER is able to quick opening through the fast workability.
That is possible to quick repair works for damaged thin area with thin cracks.
WATERPATCHER
The damage of the asphalt concrete main reason is the porthole.
The water is the direct cause.
The water is penetrate to the asphalt concrete pavement by the asphalt oxidation will degrade the adhesive properties of the asphalt.
Waterpatcher is unlike the other asphalt concrete for road maintenance properties which enhance the physical properties of water are reacted.
The construction method of waterpatcher is open the package and paving to the damaged area. And spraying water during the flatten for surface clean.
Water of injected into the waterpatcher is increasing the physical properties in combination with the materials that react with water in the asphalt binder.
Waterpatcher is different of the existing asphalt concrete, it can be constructed without removing water when the stagnant water is on the repair area .
