Other Details:

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 seal coat.

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.

Slow setting (SS): Emulsion Break is slowest and is generally used with fine aggregates. It is further subdivided into SS-1 & SS-2

Emulsion SS1 is used for Prime Coat application and perform several important functions such as coating and bonding loose mineral particles on the surface of the base, hardening and toughening the surface of the base, waterproofing the surface of the base by plugging capillary or interconnected voids, and providing adhesion or bond between the base and the asphalt mixture. This grade of emulsion penetrate quite deep in WMM / WBM surface providing an effective Prime Coat.

Bitumen emulsion SS1 is slow-setting, anionic type and are further characterized by their ability to remain stable on storage although produced with equipment that generates a wide range of shearing forces. Such characteristics are imparted to the asphalt emulsions through the use of emulsion-conditioner compositions comprising a partially desulfonated lignosulfonate, preferably an anionic or nonionic emulsifying agent and, optionally.
