Yaseen Construction Products supplies MC 70 Prime Coat Cutback Bitumen for road construction, highway development and asphalt pavement projects requiring an approved prime coat over prepared granular base layers.
MC 70 is a medium-curing cutback asphalt grade produced by blending asphalt cement with a suitable petroleum solvent. It is used to penetrate and condition compatible granular surfaces before subsequent pavement construction, where permitted by the governing road specification.
MC 70 Prime Coat is a medium-curing cutback asphalt grade used in approved road construction and pavement preparation applications.
It is commonly specified for priming suitable granular base surfaces before placing subsequent pavement layers.
MC 70 contains asphalt cement blended with a petroleum solvent. The solvent reduces the material’s viscosity to support application and penetration into suitable granular surfaces.
After application, the solvent evaporates and asphalt residue remains within and on the upper portion of the prepared base.
Yaseen Construction Products sources MC 70 prime coat for road contractors, asphalt paving companies, highway developers, infrastructure contractors and bulk construction procurement teams.
MC 70 is a medium-curing cutback asphalt grade.
The designation generally means:
MC: Medium Curing.
70: Viscosity grade designation under the applicable cutback asphalt specification.
The number 70 does not indicate a 70% asphalt content.
MC 70 is typically used where a cutback prime coat is approved for a prepared granular base.
Its use is subject to local environmental regulations, road authority requirements and project specifications.
A prime coat is a bituminous material applied to a prepared, usually unbound granular base before subsequent pavement construction.
Its functions may include:
Penetrating the upper portion of a suitable granular base.
Binding limited loose surface particles.
Conditioning the base surface.
Supporting adhesion of subsequent bituminous pavement layers.
Providing temporary surface protection within the limits of the specification.
A prime coat is not a substitute for proper base compaction, drainage or structural pavement design.
MC 70 is applied to a prepared granular surface at the specified rate.
The relatively low viscosity of the cutback asphalt allows it to penetrate the upper surface of suitable granular materials.
As the petroleum solvent evaporates, asphalt residue remains.
The performance depends on:
Granular base material.
Base density and compaction.
Surface porosity.
Moisture content.
Application rate.
Material temperature.
Weather conditions.
Solvent evaporation.
Subsequent pavement construction.
MC 70 must be allowed to cure according to the project specification before the next pavement layer is installed.
MC 70 is used as a prime coat where approved by the relevant road authority.
Its viscosity and residue characteristics are defined by the applicable material specification.
MC 30 is a lower-viscosity medium-curing cutback asphalt grade.
It may be selected for certain granular base conditions under applicable specifications.
MC 30 and MC 70 are not automatically interchangeable.
MC 250 is a higher-viscosity medium-curing cutback asphalt grade.
Its application and penetration characteristics differ from MC 70.
Selected asphalt emulsions are used as alternatives to cutback prime coats.
Their suitability depends on penetration requirements, granular base conditions and road authority approval.
Some manufacturers offer proprietary prime coat formulations for specific pavement applications.
Selection should be based on the governing specification and documented performance.

The number 70 has a different meaning in each designation.
MC 70 is used on suitable prepared granular base layers where approved.
The base should meet the specified requirements for:
Material grading.
Compaction.
Surface level.
Moisture.
Cleanliness.
Stability.
Prime coat should not be applied over loose or poorly compacted base material as a substitute for corrective work.
Highway construction projects may specify MC 70 before the first asphalt course.
The work generally involves:
Base inspection.
Surface cleaning.
Distributor calibration.
Prime coat application.
Curing.
Inspection.
Subsequent pavement construction.
The road authority may require an emulsion alternative or restrict cutback asphalt use.
MC 70 may be specified for access roads within industrial, commercial or infrastructure developments.
The correct prime coat depends on the granular base, pavement design and applicable local specification.
Industrial roads carrying heavy vehicles require a properly designed pavement structure.
MC 70 may be used as part of the approved pavement preparation system.
Prime coat does not compensate for inadequate base strength or drainage.
MC 70 may be specified for asphalt access roads and loading-area pavement construction.
The prime coat grade and application rate should match the approved pavement design.
MC 70 may be used in approved pavement works associated with:
Industrial estates.
Logistics parks.
Utility corridors.
Highway developments.
Commercial infrastructure.
Access road construction.
Project specifications determine whether MC 70 is acceptable.
Before applying MC 70:
Complete the required compaction.
Check the surface level.
Remove loose aggregate.
Remove dust and debris.
Repair unstable areas.
Confirm surface moisture.
Verify drainage.
Check weather conditions.
Obtain required inspection approval.
The base must be suitable for the specified prime coat application.
Confirm MC 70 is an approved prime coat grade.
Verify compaction, stability, moisture and surface condition.

Confirm the surface meets the road authority’s requirements for the next pavement layer.
The correct application rate depends on:
Granular base grading.
Surface porosity.
Compaction.
Surface moisture.
Required penetration.
Manufacturer data.
Road authority specification.
Excessive prime coat may leave surplus binder on the surface.
Insufficient application may result in inadequate surface conditioning.

Required quantity (L) = Surface area (m²) × Specified application rate (L/m²)
For example, assume:
Road area: 12,000 m².
Specified application rate: 0.80 L/m².
Theoretical quantity:
12,000 × 0.80 = 9,600 litres.
With an illustrative 5% allowance:
10,080 litres.
These figures are calculation examples only.
Actual consumption depends on the approved application rate, base condition and construction losses.
Possible causes include:
Dense granular surface.
Incorrect viscosity grade.
Unsuitable application conditions.
Surface contamination.
Incorrect application rate.
Possible causes include:
Excessive application.
Low surface absorption.
Incorrect grade.
Inadequate curing.
Possible causes include:
Blocked nozzles.
Poor distributor calibration.

MC 70 is a medium-curing cutback asphalt grade used to prime suitable granular road bases before subsequent pavement construction, where approved by the road authority specification.
MC means medium curing. The number 70 identifies a viscosity grade under the applicable cutback asphalt specification. It does not mean the product contains 70% bitumen.
MC 70 is used for approved granular base priming in road construction, highways, access roads, industrial roads and other asphalt pavement projects.
Both are medium-curing cutback asphalt grades. MC 30 has a lower specified viscosity than MC 70. Their penetration and application characteristics differ, so substitution requires approval.
MC 250 is a higher-viscosity medium-curing cutback asphalt grade. The correct selection depends on the granular base, application requirements and road specification.
MC 70 prime coat is used to penetrate and condition approved granular bases. SS1H tack coat is an asphalt emulsion used to promote bonding between compatible pavement layers. Their functions are different.
Yes. MC 70 may be used on properly prepared granular bases where the project specification approves it. The base must meet compaction, moisture and surface condition requirements.
Yes, where the governing highway specification permits medium-curing cutback asphalt prime coats. Some jurisdictions restrict cutback asphalt use or require approved emulsion alternatives.
The required quantity depends on base porosity and the approved application rate. For example, at an assumed rate of 0.80 L/m², a 12,000 m² surface requires 9,600 litres before losses. The actual rate must follow the project specification.
ASTM D2027/D2027M and AASHTO M 82 cover medium-curing cutback asphalt under their applicable editions. The governing road authority specification determines material acceptance and application requirements.
