Medium Setting Bitumen Emulsion MS

Break is sufficiently slow that the emulsion can be mixed with coarse aggregate containing a high proportion of fine material.

Key Features:

• Emulsion used for pot hole repair/patch work
• Suitable for 20 mm pre-mix carpet

Maintenance Mix:

This high quality material now makes it possible to fill pot holes or carry out patch repair with open graded cold premix made on-site. The methods typically used for the repair of pot holes using asphalt emulsions are throw-and-roll and full-depth removal and replacement. All of these methods involve placing cold mix in the pot hole with a shovel and compacting with a truck tire, vibratory plate compactor or steel wheeled roller.

• Blow off water and debris from the pothole
• Cut to rectangular shapes with all sides vertical
• Remove loose material, if any
• Spray tack coat of asphalt emulsion on all the side and bottom
• Mix prepared of clean (preferably washed) and dry aggregates with MS cationic bitumen emulsion
• Typically 13.2 mm and 11.2 mm sized aggregates mixed in 2:1 ratio
• MS cationic bitumen emulsion content of approximately 7 % by weight of aggregates works best
• Mix aggregates and emulsion properly to ensure good and uniform coating
• Mix till entire emulsion is broken (turns to black in color)
• Fill the premix immediately into the pot hole up to a level slightly higher than the adjoining road surface and roll properly
• Cover the repaired area with tack coat followed by a layer of 6 mm (passing) aggregate
• Open the repaired pothole to traffic as soon as workers and equipment are clear.

Premix Carpet:

For economical and fast construction of wearing course, emulsion is used for Premix Carpet. Ministry of Road Transport & Highway (MORT&H) has also recommended use of emulsion for this application in their clause 506.2. A tack coat is applied on the cleaned surface. The cold mix is prepared as per the above method and spread over the existing surface followed by either liquid seal coat or a premix

Advantages:

• No heating required
• Environment friendly
• Economical
• Ease in application
• Bond with existing surface
• Least interference with traffic
• Bonds well to cool, damp surfaces
• Low temperature cure
• Stable patches
• Resistance to peel off under traffic
• Resistance to stripping by water
• Minimal preparation time for surface repair
• Instant setting and fast development of strength
