penetration Grade Bitumen is a standard bitumen usually used as a Paving Grade Bitumen essential for road construction and for the production of asphalt pavements with superior properties, and it’s very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix.
This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grade Bitumen by Capco trading Co. is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by Capco trading Co. is produced from vacuum residue (short residue) feedstock.
Bitumen is usually characterized in the following three types of grades:
- Viscosity grades
- Penetration grades
- Density grades
Definition of penetration Grade
The penetration grades bitumen is refinery bitumen which is produced by different viscosity. In fact, Penetration bitumen is semi hard black material known as petroleum grade bitumen. The penetration test is carried out to characterize the bitumen, based on the hardness. Therefore, it has the name penetration bitumen. Penetration Grade Bitumen is a standard bitumen usually used as a Paving Grade Bitumen essential for road construction and for the production of asphalt pavements with superior properties, and it’s very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix.
Actually, it is Bitumen classified using the penetration property. Penetration grading’s basic assumption is that the less viscous the asphalt, the deeper the needle will penetrate. Bitumen which is produced during the process of oxidation of vacuum bottom (the Bitumen production feedstock that derives from distillation tower residue in vacuum oil refineries) at bitumen production unit in a manner that its penetration point (kind of test to indicate the hardness of bitumen) in specified group is classified in different grade of it.
This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.
The penetration of bituminous material is its consistency expressed as the distance in tenths of a millimeter that a standard needle penetrates vertically into a specimen of the material under specified conditions of temperature, load and duration of loading.
Grades of straight-run bitumen are designated by two penetration values, for example, 40/50, 60/70, 85/100 etc.; the Penetration of an actual sample of the bitumen in any grade should fall between the lower and upper value given.
Penetration Grades bitumen are specified by the penetration and softening point test. Designation is by penetration range only. The penetration grades of bitumen have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen.

Petroleum Bitumen Specifications
1) Penetration degree: Penetration test is used to determine bitumen hardness. In this test, a standard needle under the influence of a 100-gram load penetrates into bitumen at 25 ° C for 5 seconds. The penetration value in terms of the tenth of millimeters is called penetration degree. The lower the degree of penetration is, the harder the bitumen will be.
2) Viscosity: The higher the bitumen viscosity is, the higher solid properties it shows. Clearly, at lower temperatures, the viscosity is smaller. This property of bitumen characteristic is measured using the Saybolt Furol machine or by the kinematic method.
3) Flash point: The Flash point is the temperature that, if the bitumen reaches that temperature, the resulting gases will ignite when the flame approaches, and a flame occurs at its surface. The maximum temperature at which the bitumen can be heated in the workshop is limited to the flash point.
4) Weight loss on heating: The weight loss of bitumen at high temperature is due to the evaporation of a part of its oil and its petroleum compounds. This characteristic is also of significant properties of bitumen. The weight loss of bitumen is measured at the temperature of 163° C and within 5 hours (approximate conditions for cooking asphalt).
5) Ductility: If we pull a sample of bitumen with a cross-section of 1 cm 2 at a speed of 5 cm / min, we increase the length of the sample before tearing the ductility property of bitumen.
6) Solubility in CS2: We know the solvent of bitumen is carbon tetra-chloride and carbon-sulfur. So, if we dissolve a sample of bitumen in each of these materials, its impurities remain, and we can determine the purity of bitumen. The degree of purity is: (sample bitumen weight) ÷ [(impurity weight) – (bitumen weight)]
7) Softening point: The softening point is the temperature when the bitumen reaches that temperature, the bitumen becomes fluid. The higher the bitumen softening point, the lower the sensitivity to temperature variations. The softening point of ordinary bitumen is about 60 to 70.
Bitumen Application and Uses
Arteries Made with Asphalt
It is no surprise that most of our roads and streets are made of asphalt. Asphalt roads are more flexible to build and easier to maintain than roads using any other material. They are more cost-effective in both construction and maintenance and help reduce noise pollution. Asphalt roads are durable and are 100% recyclable. And asphalt is not just used in road surfaces: it is also a vital component of the substructure of the road, as well. And, of course, without bitumen, there would be no asphalt.
One recent advance has been the development of colored or textured asphalt surfaces. These can be used as a safety mechanism to make it easier for drivers to identify special lanes including bus lanes, bus stops, and cycle paths. Colored asphalt is also used to alert drivers to dangerous areas, such as hidden junctions or sharp bends, as well as areas requiring special safety precautions, such as outside schools.
Asphalt surfaces can be tailor-made to support the traffic load and climatic conditions of any location. There are asphalt solutions for motorways, urban, suburban and rural roads, and different solutions for high-load and bridge surfaces. In areas where roads are exposed to winter freezing and thawing, asphalt surfaces can be built to cope with extreme temperature differences, thanks to the flexibility of bitumen.
Asphalt roads can be constructed very quickly, and because asphalt effectively needs no “cure” time, motorists can use a new road soon after placement. Because of the way asphalt roads are built, they can be easily removed and resurfaced almost immediately. This is very important in urban environments where cables and pipes need to be laid or replaced under the street, as well as for general road maintenance, filling in potholes and even more so for our major trunk roads. Safe and smooth roads, with minimum delays.
Modern asphalts roads have shown to last for over 40 years and, with the correct maintenance, they can and do last even longer. Each road is built with a structurally solid base course and a protective, replaceable surface or wearing course. The layered structure is built to withstand traffic and the environment.
Modern asphalt technology ensures rapid drainage of surface water, reducing water spray and improving driver visibility in wet conditions. This reduces the risk of aquaplaning and increases the visibility of road markings. The surface texture ensures maximum grip and delivers optimal turning and braking performance, in all weather conditions. Asphalt surfaces that provide higher levels of skid resistance can be used where safety is paramount, for example on slip roads, junctions, and roundabouts.
Asphalt road surfaces can significantly reduce noise both inside and outside the car. Standard asphalt roads have the lowest noise levels of all traditional road surfaces and the most recent development of porous and silent asphalts have reduced noise levels even further. A standard asphalt surface produces half the noise compared to alternatives options such as concrete, and porous asphalt reduces this by a further 50%.
Asphalt is 100% recyclable and reusable. Recovered asphalt is routinely re-laid along with fresh materials, saving money and preserving non-renewable natural resources. Recycling also reduces the use of virgin quality gravel, reduces landfill and saves both cost and emissions for transport.
Shaping the World around us
The characteristics of bitumen give architects, structural engineers, and planners the freedom to redesign the world we live in. Bitumen membranes are water-repellent and flexible, making them ideal for waterproofing roofs and other structural elements. A natural adhesive, they can be applied to any number of substrate materials, and their natural flexibility helps to prevent rips and tears even with significant structural movement.
Bitumen membranes retain their adhesion and flexibility for a long time, and so can significantly contribute to a structure’s durability and longevity. Bituminous membranes have been used for decades and results show that a service life of 25-30 years can be expected in most applications.
Bitumen products are everywhere in modern buildings, in roofs and floors, ceilings and walls, both to protect the structural elements and to keep moisture out. Traditionally used to weatherproof low slope roofs, bituminous membranes are finding new uses in the movement towards carbon-neutral buildings. These membranes can be used to support roof gardens or eco-roofing, in both commercial and residential developments.
The correct surface is of vital importance in civil engineering projects: from bridges and tunnels to runways and parking aprons at airports. The surface needs to be strong enough to withstand each location’s different daily load and use patterns, as well as temperature differences, weather conditions and the use of aggressive de-icing technology. Bitumen products are designed to withstand the most extreme conditions and provide a safe, durable surface
Asphalt concrete with a void content of ≤ 3% is completely watertight and can be used to seal structures, basins or containers that will be used to contain water or other liquids. Asphalt can be used to waterproof dams, reservoirs, landfill sites and flood protection basins.
Part of our Everyday Life
This organic, versatile and recyclable material is never far away in the modern world – even if we don’t see it. Bitumen plays an important role in many everyday applications above and beyond asphalt streets and roofing. Bitumen’s waterproofing and adhesive properties, durability, and resistance to heavy loads make it the ideal material for use in all-weather environments. Where strength and weatherproofing are essential requirements, bitumen is a prime contributor to the performance of a vast range of products. Bitumen membranes are also extensively used as sound-deadening panels in the automobile market.
Farms use bituminous paints and disinfectants on a number of different surfaces as well as bitumen waterproofing solutions. Bitumen-based lubricants play a role in many industrial situations, and bitumen is a vital component in a range of products, from preservatives to plastics and sealants.
Modern farms rely on bitumen and products using refined bitumen for a number of vital applications. Bitumen paving provides flooring in barns, barnyards, and feed platforms while tanks, vats, and other concrete structures can be waterproofed with a bitumen solution.
Bitumen is everywhere – even in places where you wouldn’t expect to find it. It’s in a variety of grease and lubricant products for different applications, from the tracks of earth-moving equipment to traction motor gearboxes. It’s in corrosion-resistant paints and printing inks.
Bitumen is in the asphalt that paves perfectly smooth cycle paths and rugged, high-grip hiking trails, and much more. It is used to waterproof swimming pools and in numerous applications in event locations, from a huge stadium to a local playground. It’s the rubberized surface of running tracks and the waterproofing solutions used to treat outdoor clothing. In tennis courts and other sports surfaces.
BITUMEN recognized for its adhesive and cohesive assets; bitumen is often utilized in the construction industry. Bitumen is applied on road paving because it is viscous when hot, but solid once it cools down. Therefore, Bitumen operates as the binder/glue for pieces of the aggregate.
The vast majority of refined bitumen is used in construction: primarily as a constituent of products used in paving and roofing applications. According to the requirements of the end use bitumen is produced to specification. This is achieved either by refining process or blending.
It is estimated that the current world use of bitumen is approximately 102 million tons per year. Approximately 85% of all the bitumen produced is used as the binder in asphalt for roads.
Packing of bitumen in drum, jumbo bag and 300kg polycube
Packing of all grades could be same
- Drum: per 20ft container we are loading 110 drums. Each drum is 185 kg Net and 195 Kg gross weight. In case of ordering other drum sizes line 120, 145 or 150 also able to deliver.
- Jumbo bag: Another option for packing of bitumen 60/70 is jumbo bag which is 800 kg to 1200kg and able to load in 40ft and 20ft containers.
- Polycube: The best packing right now is Polycube which is 300kg bags and 80 pcs able to stuff in 20ft container. It is economic packing and cut the transport cost and compete with other packing now. 24 tons per container and no waist of bitumen during melting is the benefit.
- Bulk Packing: Bulk packing of bitumen 60/70 is two way, we transit by truck tanker which is dual layer and can remain liquid during the transit up to seven days then at destination it will discharge easily and without heating. In case bitumen get cold buyer can heat up via special channel in backside of tanker and inject the fire in the pipeline between the tank to heat the bitumen and there is exhaust on the front of tanker and the fire passing whole of tank. This way of delivery is good for neighbor customers. For far destination is not economy.
