SHESHA SCIENTI CHEM PVT LTD. Offers bitumen emulsion plant, modified emulsion bitumen plant and polymer modified bitumen emulsion plant. These plants are semi automatic and automatic plants and technology for the manufacture of Bitumen Emulsions From 3 Ton/hr to 10 Ton/hr . Our Plants are designed for manufacturing cationic and anionic grades of emulsion mainly termed as RS (Rapid Setting),MS (Medium Setting) and SS (Slow Setting Emulsions). Our Engineers Offer Complete On-Site Training with respect to installation,formulation,testing and running of the plant. EMULSIONS ARE USED AS A BINDER IN THE CONSTRUCTION OF ROADS. All our bitumen emulsion plant, modified emulsion bitumen plant and polymer modified bitumen emulsion plant are IRDA approved. WHY USE BITUMEN EMULSIONS? Standard flexible road structures consists of layers of manufactured materials laid onto an roadbed soil. The upper portion of the roadbed soil is commonly exposed to harsh environmental and heavy traffic leading to distortion and subsequent cracking of the upper surface layers. It is not economically viable to excavate the complete structure and therefor emulsion mixes are used successfully to follow roadbed soil movement without cracking. It has been proven that emulsion mixes have membrane-like mechanical properties rather than the slab-like properties of standard hot bituminous mixtures. Furthermore, emulsion mixes are not as susceptible to thermal cracking as regular standard hot bituminous mixtures. PRINCIPALS OF EMULSIONS MIXES An emulsion is a mixture of two immiscible liquids, one of which is dispersed in the other in the form of very fine particles. The process of emulsification is accomplished by use of an emulsifier and a stabilizer. Emulsion mixes are used as a base layer in a pavement structure as well as a surfacing course. They are obtained by dispersing a cationic bitumen emulsion in an aggregate and can be produced in cold mix plants as well as with mix-pavers. The application rates vary from 50 mm to 200 mm in thickness. The binder within an emulsion stabilized granular material selectively coats smaller particles. The stiffness of emulsion mixtures is lower than Hot Mix Asphalt. Unlike Hot Mix Asphalt, the manufacturing of emulsion mixes does not require heat. The surface of emulsion mixes is relatively fragile when compared to the surface of Hot Mix Asphalt. Unsealed emulsion mixes do not provide waterproofing and the cohesion at the surface may not be sufficient to withstand surface tangent stresses. By sealing the surface emulsion mixes, waterproofing is achieved and the inherent performance of emulsion mixes is not compromised by premature stripping, oxidation and raveling.
