Asphalt emulsions can be used in almost any type of pavement applications. They can be used for preventive and corrective maintenance of asphalt and concrete pavements, stabilization and recycling of foundations, construction of structural pavements and recycling of old pavements. Recycling with bitumen emulsion is an environmentally friendly way to reduce costs and reuse paving materials. Bitumen emulsions were created in the early 1900s for dust control and other spray applications. Emulsified asphalt is simply a suspension of small asphalt cement globules in water, which is assisted by an emulsifying agent. 
Tack Coats Viscous or adhesive coatings are spray applications of bituminous emulsions that provide adhesion between the existing pavement and the new overlay. Adhesive coatings significantly increase pavement strength and fatigue life at a lower cost. A good tack coat provides a uniform thin, sticky, sticky film that won't fray off the road or cause slippage between the old and new pavement surfaces. The viscous coating is sprayed at a uniform rate with a bitumen dispenser. Allow the sprayed lotion to break down before applying the new surface. Chip Seals Chip sealing is a surface treatment designed to extend and protect the life of pavement. Long-term pavement performance studies have shown that chip sealing is one of the most cost-effective methods of pavement protection. Chip sealing is ideal for pavements with loss of surface texture and as a preventive maintenance treatment for pavements that are aging in good condition with minimal surface damage. Slurry Seals Slurry sealing is a mixture of aggregates, emulsions and mineral fillers that are mixed and placed by a machine. Clay seals are designed to seal pavement, restore a uniform texture and appearance, and provide good slip resistance. Mud seals are available in three overall sizes. Type I uses fine aggregates and is designed for parking lots and taxiways. Type II is the most commonly used one, uses a coarser aggregate and can be used on main roads, residential areas and highways. Type III uses the thickest aggregates and can be used on highways, highways and racetracks. 
Micro Surfacing The microscopic surface consists of densely graded aggregates, polymer-modified asphalt emulsions, water, mineral fillers and other additives. Micro surfaces are stronger and more durable than slurry seals. The fast-setting micro surface emulsion allows traffic to start using a new surface in about an hour. There are generally two aggregate sizes for micro surface treatment. Type II is the most common and uses coarse aggregates. It is suitable for all applications including main roads, residential areas, highways and airports. Type III aggregates are thicker and are used on heavily trafficked sidewalks, highways, and airport runways. Full Depth Reclamation Full-depth reclamation is a cost-effective technique for reclaiming dilapidated pavements and providing a structurally sound foundation for existing roads. Full-depth correction is an ideal treatment for thin asphalt pavements that have serious problems such as ruts, cracks, potholes and base problems. Full-depth reclamation is also a good option for strengthening the shoulders. Full depth reclamation has seriously painful pavements. It could also be the first step in phased construction – adding more structures to meet increased traffic or widening roads. Hot In-Place Recycling Hot In-Place Recovery (HIPR) repairs asphalt pavement on site. The process typically removes 1 to 1-½ inches of pavement, mixes it with the emulsion, and places the recycled admixture on the existing pavement for continued operation. Before milling, heat the pavement to about 300°F (150ºC) to soften the surface. 
The top 1 to 1-½ inches of loose pavement is then mulched with the ground and asphalt emulsion. The rejuvenating mixture is held in place by a paver with a vibrating screw. Benefits of HIPR include preventing and filling cracks; smoothing ropes, bumps and potholes; rejuvenate the old pavement; and re-establishing drainage and pavement cross-sections. Cold In-Place Recycling Cold-in-place recycling (CIPR) involves rebuilding asphalt pavements that have suffered severe damage, including lateral cracking, wheel ratting, deformation, oxidation, and potholes. The CIPR process removes old pavement material, crushes and restores it to a new pavement structure. Benefits of CIPR include repair of severely damaged sidewalks, smoothing of potholes, potholes, bumps and leveling. Benefits include reducing the transport and use of virgin material, rebuilding drainage and crowns, rejuvenating old pavement and improving slip resistance. Dust Palliatives Dust reducing agents are thin bitumen emulsions that reduce dust on rough roads. Most dust reducing agents are sprayed on unpaved roads in small amounts by bitumen dispensers. Application rates range from 0.1 to 0.35 gallons per square yard. This surface treatment can be used for asphalt or concrete pavement maintenance. It can also be used as a surface for new asphalt pavement construction. The treatment is a single-shot paving process that uses a special machine to spray a polymer-modified bitumen emulsion, followed by a special screw to hold an ultra-thin hot mixture. 
Ultra-thin mats, typically "thick, use high-quality aggregates while maintaining overhead clearance and curb height. Ultra-thin materials are compacted with stationary rollers ranging from 8 to 10 tons. This treatment Provides a durable, waterproof wearable surface. Driveway Sealers Asphalt emulsion driveway sealant consists of polymer modified emulsions with additional fillers and polymers. They are eco-friendly and contain no bitumen. They rejuvenate the surfaces of aging pathways and seal in water. Asphalt emulsion sealants effectively protect driveways. Polymer-Modified Emulsions Polymer-modified emulsions provide longer life and cost savings and allow the use of emulsions in applications where conventional asphalt emulsions cannot function effectively. Polymer-modified emulsions offer the same environmental benefits as conventional emulsions, with increased durability. Polymer-modified emulsions can also provide overall cost savings. Highways and other sidewalks can now be treated with polymer-modified sealant coatings instead of more expensive technologies. Polymers can be as elastic as rubber or as hard as a bowling ball. Its elasticity becomes evident during the curing process and throughout the life of the pavement. The adhesion of aggregates is rapid and allows the use of localized aggregates that may not perform well with unmodified emulsions.
