Manufacturer of Cutback Bitumen MC-70 for waterproof of surfaces, Tack Coat, from Dubai-UAE

Cutback Bitumen MC-70 is medium curing (MC) cut-back asphalt consisting of penetration grade asphalt cement and diluent or cutter of medium volatility. The diluent temporarily reduces the viscosity of the asphalt cement for ease of handling and application. After application, the diluent evaporates, leaving asphalt cement to perform its function. Cutback MC-70?use in Roofing – As a waterproofing membrane and as an adhesive to stick chippings onto a flat, horizontal roof to minimize the effects of weathering from the sun.?Cutback bitumen MC-70 is dissolved of bitumen in solvents of kerosene. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen. ?The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long-term softening effect may result. Our MC-70?Cutback Bitumen complies with cutback petroleum asphalts of the Medium-Curing type for use in the construction and treatment of pavements as per ASTM D2028-97?reapproved in?2004.?Cutback Grade Bitumen is normally used in spraying and in some mixing applications. Cutback Bitumen is penetration grade bitumen blended with a solvent such as kerosene, white spirit, gasoline, and naphtha, controlling the curing time. Cut back petroleum asphalts of the rapid curing type supplied by RAHA OIL are petroleum grade bitumen manufactured from the fractional / vacuum distillation of crude oil blended with a solvent. Bitumen supplied by RAHA OIL? is produced from the vacuum residue (short residue) feedstock. Penetration Grade bitumens are specified by the penetration and softening point test. Designation is by penetration range only. The penetration grade bitumens 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. The cutback bitumen (Asphalts) supplied by RAHA OIL are blended from petroleum grade bitumen as stated herein.

EXPLANATIONS ABOUT CUTBACK BITUMEN MC-70

Cutback Bitumen MC70 is a type of dissolved Bitumen. To produce this type, solvent oils such as kerosene are used in order to change bitumen into dissolved bitumen or liquid pitch, so that, during the consumption process, the solvent oil evaporates and bitumen residue to obtain the desired adhesion. In many countries, kerosene and other volatile petroleum-derived products are added as a cutter or cutback agent to bitumen to reduce (or cutback) the viscosity of the bitumen. The mixture obtained may be called cutback bitumen. Medium curing is the most common category in cutback bitumen, among which, MC-70 grade has the highest demand. MC-70 is a medium curing cutback bitumen that contains 55% bitumen and has the lowest viscosity among all grades. It is black in color and is manufactured strictly as per the ASTM D 2027M-13 standard. Its commonly used as a Prime Coating. It is homogeneous and will not foam (as observed visually) when heated to application temperature. MC-70 is?medium curing (MC) cut-back asphalt?consisting of penetration grade asphalt cement and diluents or cutter of medium volatility. The diluents temporarily reduce the viscosity of the asphalt cement for ease of handling and application. Cutback MC-70 use in the road maintenance industry where it is used as a prime coat of the base course prior to placing the bituminous surface course.

USES OF CUTBACK BITUMEN MC-70

Cutback agents are used to lower the viscosity of bitumen when it is applied as a primer to the surface of a road pavement aggregate base course or substrate. Kerosene is used as a bitumen cutback agent at different concentrations according to local conditions and requirements. The cutback bitumen is ideal for prime coat and cold applied because of easy uses and no need to thinning and heating. Cutback bitumen MC-70 consist of initial incorporation of asphalt into the surface of non-asphalt based course preparatory to any superimposed treatment of construction. The cutback asphalt MC-70 applying to waterproofing of surfaces, plug capillary voids, coat and bond loose mineral particles. Current common uses are in penetrating prime coats and in producing patching or stockpile mixtures. Cutback asphalt used in mixing with aggregate will usually contain an adhesion agent to assist in the coating of the aggregate surface. The reduction in viscosity of the bitumen aids the construction of seal coats in road pavements as the softened mixture wets the chips more easily. The cutback agent evaporates from the seal coat, the cutback agent becoming a negligible component of the seal coat a few months after application. If significant amounts of the cutback agent remain in the seal coat an unwanted long term softening effect may result

Mixed-in-place (road mix):

• Pavement base and surfaces with sand

Bitumen applications:

• Prime coat on open surfaces
• Prime coat on tight surfaces
• Dust binder

The cutback asphalt MC70 applying to waterproof of surfaces, plug capillary voids, coat, and bond loose mineral particles. Meanwhile, Cutback Bitumen MC70 are used as components for road maintenance industry where it is used as a prime coat of the base course prior to placing of the bituminous surface course. This type of Bitumen is most commonly used as an adhesive material between road foundation and asphalt coating, in the road construction industry which includes superstructure and foundation. Cutback Bitumen MC70 is used Priming of all non-bituminous road buses, provision of temporary surfaces(deviations) Also, Cutback Asphalt MC-70 is suitable for primer sealing and can also be used in the manufacturing of asphalt pre-mix. Cutback bitumen is used extensively in sprayed sealing applications, particularly in colder weather where they proved improved initial stone retention due to their lower viscosity. Other uses include roofing as a waterproofing membrane and as an adhesive to stick chippings onto a flat, horizontal roof to minimize the effects of weathering from the sun.

APPLICATION OF CUTBACK ASPHALT MC-70

• Although MC 30 is pump-able at ambient temperature, heating of the binder is recommended prior to spray applications.
• Special care must be taken whilst heating, as MC 30 contains flammable cutters that have a flashpoint of >40°C.
• Before priming, the surface of the base course should be well swept.
• The moisture content of the base course should be less than 50% of the Optimum Moisture Content.
• If the base is very dry, dampen slightly with water to prevent the formation of “fish eyes”.
• Apply with a calibrated distributor at a binder spray temperature of 55°C and a minimum road surface temperature of 10°C and rising.
• Drying time is dependent on the porosity of the base course as well as on the prevailing weather conditions. The prime must be allowed to dry before opening to traffic or proceeding with the construction of the surfacing

PROPERTIES OF CUTBACK BITUMEN MC-70

MC-70 is blended to a low viscosity to ensure that it penetrates the top 10mm of the base with the aid of the cutter, whilst depositing a thin film of bitumen on the surface to provide adhesion between the base coarse and the new surfacing.

SAFETY OF CUTBACK BITUMEN MC-70

• Refer to Safety Data sheets before use.
• Transport, use and store at the lowest temperature possible.
• Eliminate all potential ignition sources during application.
• Avoid breathing vapors. Avoid contact with skin.
• Always wear appropriate PPE including heat protection when used hot.
• DO NOT allow product or washings to enter stormwater or sewer systems.
