Viscosity Grade Bitumen 10

Viscosity Grade Bitumen 10 Description

Viscosity grade 10 of bitumens are categorized according to Viscosity (degree of fluidity) grading. The higher the grade, the stiffer the Bitumen. In Viscosity Grade, Viscosity tests are conducted at 60°C and 135°C, which represents the temperature of the road surface during summer and mixing temperature respectively. The penetration at 25°C, which is the annual average pavement temperature, has been also retained in Specifications. Viscosity Grade Bitumen 10 is mostly used in spraying applications such as paving in cold regions. VG 10 is an alternative for bitumen 80/100 penetration grade. It also acts as a feedstock in manufacturing Bitumen Emulsion and Modified Bitumen products.

Viscosity grade of bitumen can be done on original (as-supplied) asphalt binder samples (called AC grading) or aged residue samples (called AR grading). The AR viscosity test is based on the viscosity of aged residue from the rolling thin film oven test. With AC grading, the asphalt binder is characterized by the properties it possesses before it undergoes the HMA manufacturing process. The AR grading system is an attempt to simulate asphalt binder properties after it undergoes a typical HMA manufacturing process and thus, it should be more representative of how asphalt binder behaves in HMA pavements. Table 1 lists key advantages and disadvantages of the viscosity grading system.

Bitumen Mastic

Bitumen Mastic Definition

Bitumen Mastic is a type of asphalt composed of suitable graded mineral and asphaltic cement, also to take in proper proportion to consistent mass solid or semi-solid form. when it is heated it is in fluid form and then becomes solid.
Mastic asphalt (MA) is a dense mixture consisting of coarse aggregate, and/or sand, and /or limestone fine aggregate, and/or filler and bitumen, which may contain additives (for example polymers, waxes). The mixture is designed to be of low void content. The binder content is so adjusted that the voids are completely filled and that even a slight excess of binder may occur. Mastic asphalt is pour-able and able to be spread in its working temperature condition. It requires no compaction on site.
On the other hand asphalt mastic – abbreviation AM – is a term used in Europe to describe a mix of sand (that is, without aggregates > 2 mm), and/or limestone fine aggregate, and/or filler and bitumen that is used especially for waterproofing in a variety of applications.
The formulation of the mixture is chosen as a function of
– field of application
– mechanical load
– thermal load
– chemical load
– climatological influences.

Bitumen Mastic Applications

Bitumen Mastic is used for concrete and ordinary red brick masonry with cement plaster surface is the basic method for the construction of floors, foundation, tanks, etc. To protect the commercial and civil structure of plants and building from corrosive attack acid-resistant brick lining is mostly used, Bitumen Mastic has good resistance to weak, diluted acids, alkalis salts, etc, also used as open mastic flooring for heavy-duty flooring.
It is used in:
– Bridge decks
– Flooring (building)
– Flooring (industrial)
– Road construction
– Rooftop car parks
– Hydraulic constructions
– Flat roofing
– Tanking

Production Process

In the past, that means approximately until 1970, mastic asphalt was often manufactured in mobile cookers (usually at the worksite) that were filled with the various components. By slowly heating them, the components were brought to the right temperature, where the mix-ing device (then mostly a horizontally rotating mixer shaft) served to make sure that the mix was homogeneous for processing. Of course, in this way, no high production rates could be achieved.
Nowadays mastic asphalt is manufactured in (specially designed) stationary industrial plants. These are designed to proportion the materials, dry the mineral aggregates, and mix them in a heat-controlled environment. Application specifications control the temperatures at which material is produced. Typically, in the past, mastic asphalt production temperatures were in the range of 230 to 270 ºC. However in recent years considerable research and investments have been done (and are still ongoing) to lower these temperatures beneath 230 ºC – in some countries even below 200 °C.

Packing

Bitumen Mastic is available in 25 Kg Carton Box & 20 Kg new steel drum.

Bitumen Roll Sheet

What Is Bitumen Roll Sheet?

Waterproofing Bitumen Membrane Sheet Or Bitumen Roll Sheet Or Bitumen Roof Sheet (Here referred to as WPBS) is the best industrial outcome in the area of waterproofing ever attained by scientific and technological advancement. These products enable us to prevent the adverse effects of rain and snow water penetration into structures from their foundation up to the roof. Employing different polymers and synthetic fibers, WPBS passes through well-equipped labs to be amended for attaining resistance against, high and low temperatures, tearing tension, and penetration of water.

In addition to low weight and resistance against cold, heat, expansion, and contraction, WPBS shows high endurance being produced in two aluminum-covered and polyethylene film-covered versions. There two types of base products: single-layered (nonwoven Spunbond polyester), and double-layered (stringed fiber gloss tissue and 110 gr polyester) giving the product higher tensile strength against vibrations of the structure. WPBS is used in waterproofing of roofs, water canals, the foundation of tunnels, dams, pools, sloped surfaces, and the like.

A bituminous waterproofing membrane is used for reinforced concrete roof waterproofing. This waterproofing membrane comes on-site in the form of rolls manufactures and packed in the factory properly sealed.
The specifications and safety manuals of these membranes provided by the manufacturer should be read before the installation process. Fire safety and prevention is the most important while using this membrane.
All inflammable materials from roofs to be removed and good roofing practices should be followed.
The bituminous waterproofing membranes are unfolded on the site and laid firmly on the surface with tar-based adhesives using blowtorches. A layer of bituminous waterproof membrane is laid over the structural roof which acts as a shield against the seepage of water onto the roof. Roof tiles & membrane is applied over the filler material laid to slope to pass the flow of water into drains. A proper slope is necessary to allow the water to flow steadily to drains. These membranes have 2 to 4 mm thick waterproof materials. The membrane should be flexible with elongation of 150 % to cover any small cracks, strong, chemical & UV resistant, flexible enough to take any shape over which it is laid.

base course asphalt.

Summary of benefits

The Viva standards to which C600 bitumen is made result in a very consistent bitumen with predictable handling and performance characteristics

Bitumen C600 Applications

C600 bitumen is the hardest paving grade bitumen available in Australia and is mainly used to produce high modulus
asphalt. Heavy-duty asphalt pavements need to be designed to accommodate significant traffic loadings for up to 40
years without exhibiting structural failure and hence, need to be constructed using appropriate materials. The load
spreading characteristics of pavement layers are governed by their stiffness and C600 bitumen facilitates the production of high modulus asphalt.

Health & safety

C600 is unlikely to present any significant health or safety hazard when properly used in the recommended
an application where good standards of industrial practice are maintained.

Bitumen C600 Typical characteristics

Bitumen, also known as asphalt in the United States, is a substance that forms through the distillation of crude oil. It has waterproofing and adhesive properties. Bitumen production through distillation removes lighter crude oil components, such as gasoline and diesel, leaving the “heavier” Asphalt behind. The producer often refines it several times to improve its grade. Bitumen can also occur in nature: Deposits of naturally occurring bitumen form at the bottom of ancient lakes, where prehistoric organisms have since decayed and have been subjected to heat and pressure.
