Cutback Bitumen MC-30
Cutback Bitumen MC30 Description
Cutback Bitumen MC-30 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-30 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.
Cutback Bitumen MC30 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-30 grade has the highest demand. MC-30 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.
Cutback Bitumen MC30 Applications
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.
Cutback Bitumen MC30 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 MC30 is used Priming of all non-bituminous road buses, provision of temporary surfaces(deviations)
Also, Cutback Asphalt MC-30 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.
Surface treatment:
- Prime Coat on Tight Surface
- Tack Coat
- Road Mix
Advantages:
- Easy to Apply
- Limitless Lifetime & Durability
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.
- 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 MC30
MC30 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.

Slow Curing Cutback Bitumen
Slow Curing Cutback Bitumen Description
Slow curing Cutback Bitumen and oils of low volatility generally in the heavy distillate range (SC–70, 250, 800, 3000). The degree of liquidity developed in each case depends principally on the proportion of solvent to asphalt cement. To a minor degree, the liquidity of the cutback may be affected by the hardness of the base asphalt from which the cutback is made. The degree of fluidity results in several grades of cutback asphalt some quite fluid at ordinary temperatures and others somewhat more viscous. The more viscous grades may require a small amount of heating to make them fluid enough for construction operations.
Slow Curing often called “road oils,” are usually a residual material produced from the fractional distillation of certain crude petroleums. Traditionally any kind of aromatic, naphthenic and paraffinic oils are used. Slow Curing liquid bitumen materials can be prepared by blending bitumen with an oily petroleum fraction.
Slow Curing Cutback Bitumen Applications
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.
Cutback agents are used to lowering 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.

To a minor degree, the liquidity of the cutback may be affected by the hardness of the base asphalt from which the cutback is made.

The more viscous grades may require a small amount of heating to make them fluid enough for construction operations.
Slow curing (SC) cutback asphalt are often called road oils and are used primarily in road-mixing and dust-laying applications. This term originated in earlier days when asphalt residual oil was used to give roads a low-cost, all-weather surface. SC cutback asphalts are also used for stockpile patching mixes, plant-mixed with graded aggregates and occasionally for priming.
Medium Curing Cutback Bitumen
Medium Curing Cutback Bitumen Description
Medium Curing Cutback Bitumen is a compound of different oil solvents such as kerosene in order to transform bitumen to soluble bitumen which is evaporated in oil solvent using process and the bituminous layer is remained to make cohesion, penetration and form a sealing layer. A famous sort of it known as MC250 or liquid bitumen in asphalt section including pavement (cohesive between 2 Tack coat asphaltic layers), cold asphalt (Roadmix) and substructure (cohesive between asphaltic and soil layers-Prime coat) has been previously used. Available kerosene in MC250 would lead to promoting bitumen restoration, better penetration in infrastructure application (Primecoat) but yet will increase environmental hazards, price and heating cost in using and discharging time comparison with various types of water-based emulsions. Bitucut bitumen is produced and supplied in these types: MC800, MC250, MC70, MC30 and MC3000 which have the different percentage of solvent. Bitucut usage differs in various conditions such as substructure (continuous grading with low free space, open grading, and soil percentage). Using Bitucut in substructures (Primecoat) is the most demanded application.
Medium curing (MC) cutback asphalts are defined as those asphalt grades, which are prepared by using the medium volatile kerosene as the prime coat with boiling point ranges (MC-30, 70, 250, 800, 3000). The mix is done in a cold manner.
Cutback bitumen or asphalt is classified based on the curing as follows, 1) Slow, 2) medium and 3) rapid curing.
The degree of evaporation in the medium curing cutback asphalt is intermediate because the kerosene is intermediate volatile liquid as compared to the naphtha and diesel. The degree of liquidity depends on the proportion in which the kerosene is mixed in the asphalt cement.
The following specification for the medium curing cutback asphalt with its properties are as given below.
The medium curing cutback asphalt is used in the flexible pavements for surface dressing, prime coating, and tack coating. Evaporation of the solvents will be at a moderate rate. This grade is used with aggregates for ensuring better work-ability in the mix.
The degree of liquidity developed in each case depends principally on the proportion of solvent to asphalt cement. To a minor degree, the liquidity of the cutback may be affected by the hardness of the base asphalt from which the cutback is made. The degree of fluidity results in several grades of cutback asphalt—some quite fluid at ordinary temperatures and others somewhat more viscous. The more viscous grades may require a small amount of heating to make them fluid enough for construction operations.
The medium setting grades are designed for mixing with aggregates. Because these grades do not break immediately upon contact with aggregate, mixes using them can remain workable for extended periods of time and lend themselves to cold mix stockpiles.

A cutback bitumen medium curing MC is simply a combination of asphalt cement and petroleum solvent. Like emulsions, cutbacks are used because they reduce asphalt viscosity for lower temperature uses (tack coats, fog seals, slurry seals, stabilization material).
Similar to emulsified asphalts, after a cutback asphalt is applied the petroleum solvent evaporates leaving behind asphalt cement residue on the surface to which it was applied. Cutback asphalt is said to “cure” as the petroleum solvent evaporates away. The use of cutback asphalts is decreasing because of environmental regulations.

Rapid Curing Cutback Bitumen
Rapid Curing Cutback Bitumen Description
Rapid curing cutback Bitumen cement is a combination of light diluents of high volatility, generally in the gasoline or naphtha boiling point range (RC-70, 250, 800, 3000), and asphalt cement.
Cut-back asphalts is defined as the bitumen whose viscosity value will be greatly reduced by the addition of volatile diluents (high viscosity). It mainly depends upon the diluents used. Generally, three types of cutbacks are used as follows, 1) rapid curing, 2) medium curing and 3) slow curing.
Rapid curing cutback asphalt combinations are prepared starting from the lighter diluents, and even from the fluid of higher viscosity. The grades used for rapid curing cutback bitumen are RC-70, RC-250, RC-800 and RC-3000. Here, the value given by numbers 70, 250, 800, and 3,000 represents the kinematic viscosity of the bitumen given in centistokes. The solvent concentration of rapid curing asphalt is 15-45% of the volume of asphalt cement used.
Different degrees of fluidity exists for each case and it depends on the proportion of the solvent of asphalt cement. In a minor degree cutback, liquidity may get affected by the hardness of base asphalt from which the cutback is made. It is used for the prime coats.
It is used in the pavement design process. It reacts quickly for the spray applications of bond and tack coats. It is helpful to seal the aggregate chips and sand seals. Rapid curing asphalts are mainly used for surface treatment.
Cut back asphalt RC 800 is useful for waterproofing surfaces and plug capillary voids. Grade RC250 acts as a seal coat in roadway pavements.
Mainly two tests are conducted on cut-back asphalt and are given as 1) residue and 2) cut back test. The testing of residue focusses on examination of penetration, ductility, and solubility. The testing of cutback bitumen includes the distillation, viscosity and flash point tests.
The degree of liquidity developed in each case depends principally on the proportion of solvent to asphalt cement. To a minor degree, the liquidity of the cutback may be affected by the hardness of the base asphalt from which the cutback is made. The degree of fluidity results in several grades of cutback asphalt—some quite fluid at ordinary temperatures and others somewhat more viscous. The more viscous grades may require a small amount of heating to make them fluid enough for construction operations.
Cutback Bitumen Rapid Curing Applications
Rapid Curing Cutback Bitumen is made by reducing the viscosity of and ordinary bitumen by adding mostly petroleum type solvent. Cutback Bitumen are used because their viscosity is lower than that of neat asphalt and can thus be used in low-temperature applications.
The rapid-setting grades are designed to react quickly primarily for spray applications, such as bond/tack coats, aggregate chips seals, sand seals and similar surface treatments.
Rapid curing Cutback bitumen are typically used as prime coats and tack coats. Generally, Cutback Bitumen are divided into three groups depending on their volatility of the solvent added
After a RC cutback is applied the solvent evaporates away and only the Bitumen is left. A rapid curing cutback bitumen is said to cure as the petroleum solvent evaporates.
