Bitumen because of its adhesive and cohesive assets most using in construction industries. In environment temperature the bitumen has solid mode but by warming it become to the sticky liquid slowly.
So Bitumen is acting like sticky glue in construction pieces. Bitumen in environment temperature and normal pressure of atmosphere is not volatile. Its color normally would be dark black or dark brown and its has waterproofing and adhesive properties but we must mention that it has two different properties too our mean is cohesiveness and durability.
Most of the refined pure bitumen is using in construction projects like Asphalt paving and roofing felts.
And due to the different constructions industries uses it is producing with different standard specifications. We must mention that for producing any specification of Bitumen must use different refining process.
As we mentioned before bitumen in room temperature would be in solid mode and in high temperatures would be in liquid mode.
The liquid temperature of Bitumen would be normally between 160 – 180 Centigrade and in Asphalt paving projects in cities normally the bulk bitumen is handling with these temperatures.
And for some of other projects and exporting bitumen will transport in normal solid mode with normal temperature of environment for example in steel drums or in jumbo bags those are very good for transportation.
Bitumen according to its penetrations and specifications will use in different weather with different properties for example in cold weathers the it is using with higher penetration and in hot weather it is using with lower penetration for Asphalt and roofing felt projects because of its different resistance in front of heat of sun and environment.
Polymerized process will make its strength, cohesiveness, resistance , stripping and deformations very better and it can use for infrastructures very better than normal mode.
Very important additive that must use in polymerization process would be styrene butadiene styrene or SBS that will increase its binder specification and its elastomeric will increase and finally all of the projects that made with Polymerized bitumen will have more life time than others
it will act like that in big traffics it will hold the aggregates together and preventing the surface of road or high way from breaking we are calling this advantage raveling. It will increase cohesion energy and much more energy is required for breaking because its elasticity increased. As a results Asphalt that made from this mix will have less sensitive to raveling and its viscosity would be more than normal.
But if the viscosity would be very high will make problem because its pumping would be very hard and can not doing good coating process and the final mixed Asphalt will compact good.
Polymer modification process will improve its resistance to aging and when it is using on the roads or high ways its resistance and its life will increase in front of oxidation by air, UV light, water, changes in temperatures. In the other hand all of these problem are with traffic over loads too and if it would not be polymerized it will be become to stiffen and come more brittle. But by doing polymerized process this aging process will decrease and durability will increase. If we want to say better the polymerization process will decrease its fatigue.
Our means from fatigue would be cracking on Asphalt and repetition of loading cracking cycles in Asphalt and this is reason of failure of many pavements.
The polymerized one have very high resistance in front of fatigue and in this position the asphalt will damage very low and will have long life.
We are supplier of Bitumen according to the (NIOC) Standard for exporting to countries who are interesting in high quality penetration Bitumen.
