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

Tack coat application is a light spray of Bitumen Emulsion, which may be hand or machine sprayed. It is used to ensure a good bond between an old and a new bituminous surfacing layer. It is normally applied very thin and evenly over the entire suface.

It consists of application in one or two coats, each consisting of a layer of bituminous binder sprayed on a previously prepared base, followed by a cover of stone chips rolled into form a wearing course. RS-2 type cationic Bitumen Emulsion is ideal for surface dressing on the shoulders and for protection of freshly laid base course. Typical rate of application for two coat surface dressing as per(MORT&H) CLAUSE 510.2 IS 28-32KG/10SQ.M.

This is an absorptive surface material (like low to medium high porosity wet mix macadam or water bound macadam), designed to penetrate, plug the capillary voids in the surface, bond and stabilize the existing surface and to promote adhesion between it and the construction course that follows.
