Plasto-Elastic Iran Polymer Modified Bitumen
Description of Plasto-Elastic Iran Polymer Modified Bitumen
RAHASEAL is a single component, hot-applied plasto-elastic polymer modified bituminous Concrete Paving Joint, crack, and expansion joint sealant, specially formulated to be used into horizontal expansion joints and cracks. The sealant is supplied in solid form and can be applied using sealing melter applicator units.
Uses of Iran Polymer Modified Bitumen
- Concrete operon and Airport band
- Concrete paving highways, runways, and taxiways
- Concrete Roads
- Multistory parking decks
- Expansion joint in bridges and other concrete structures
Advantages of Iran Polymer Modified Bitumen
Due to high polymer content, RAHASEAL is viscous enough at application temperature to fill the cracks satisfactorily, and also is liquid enough to penetrate into all tiny holes of cracks and protecting them from penetrating water.
Application of Iran Polymer Modified Bitumen
Crack configuration
- Minimum Crack depth: 10 mm
- Width/Depth ratio: 1/1.5
Surface preparation
All surfaces must be clean, dry and free from all loose adhering particles.
Heating
Heat up to 170 ±5 ºC in a controlled oil bath or oil jacket melting-vessel with agitator until a smooth, even and pour able consistency is achieved.
Application
Apply by melter-pourer or for detailed work use a metal-lipped bucket. Sealing may be done at the environment temperature of 4ºC and higher.
Cleaning
Clean all tools and equipment immediately after use with Kerosene or other appropriate solvents
Safety Instructions
Safety precautions
Wear goggles and gloves during application. In case of contact with eyes immediately wash them with plenty of water and start first aids.
