Dwarkesh Chemicals Pvt. Ltd. offers a comprehensive range of Bitumen and Bitumen Emulsions for road construction, infrastructure development, industrial applications, waterproofing, and other specialized uses.
Our sister concern, Jainam Alternate Energy Private Limited (formerly known as Pithampur Petro Pharma Private Limited), is a flagship company of the Jainam Group, headquartered in Ahmedabad, Gujarat, India. The company operates a dedicated manufacturing facility at Pithampur, District Dhar, Madhya Pradesh, for the processing and manufacture of various grades of Bitumen and Bitumen Emulsions.
Backed by a professionally qualified and experienced team with more than three decades of expertise in specialty oils and petroleum products, the manufacturing facility produces a wide range of bituminous products designed for diverse infrastructure and industrial requirements.
Our product portfolio includes:
Paving Grade Bitumen is a straight-grade bituminous binder widely used for road construction, road maintenance, airfields, and other infrastructure applications. Common penetration grades include 60/70 and 30/40, depending on the required pavement performance and application.
Straight-grade bitumen is obtained as a residue from the crude oil distillation process. The refinery-produced bitumen is further processed under controlled conditions to achieve the required properties and specifications for paving applications.
Our paving-grade products are designed to provide suitable performance across varying temperature and traffic conditions, helping improve pavement durability and resistance to common problems such as cracking and rutting.
VG-30 Bitumen is a viscosity-grade bitumen primarily used for the construction of heavy-duty roads and pavements subjected to substantial traffic loads. It can be used as an alternative to 60/70 penetration-grade bitumen in suitable applications.
VG-30 provides a balanced combination of viscosity and temperature performance, making it suitable for road construction in a wide range of climatic and traffic conditions.
VG-40 Bitumen is a higher-viscosity grade designed for highly stressed pavement locations, including road intersections, toll plazas, truck parking areas, and other locations exposed to heavy traffic and high loading conditions.
Its higher viscosity helps produce stiffer bituminous mixes, improving resistance to rutting, shoving, and deformation under heavy traffic and elevated pavement temperatures.
Viscosity Grade (VG) Bitumen provides several advantages over conventional penetration-grade classification:
Industrial Grade Bitumen is produced by further processing straight-grade bitumen under controlled conditions. The extended processing modifies the material's penetration and softening characteristics, producing oxidised or blown bitumen with properties suitable for a wide range of industrial applications.
Industrial-grade bitumen is available in different grades based on softening point and penetration values, including grades such as 85/25, 90/15, and 115/15, subject to applicable specifications.
Industrial Bitumen and Oxidised Bitumen are used in applications such as:
Bitumen Emulsion is a dispersion of bitumen droplets in an aqueous phase, stabilized using suitable emulsifying agents. It provides a workable form of bitumen that can be applied at or near ambient temperatures, making it particularly useful for road construction, road maintenance, surface treatment, and repair applications.
Bitumen emulsions are available in different types, including Anionic, Cationic, and Nonionic emulsions. The appropriate emulsion depends on factors such as aggregate characteristics, climatic conditions, application method, and project requirements.
Cationic Bitumen Emulsions are widely used because of their strong adhesion to mineral aggregates and suitability for a broad range of road construction and maintenance applications.
Bitumen is one of the most widely used binding materials in road construction and maintenance. When mixed with mineral aggregates, bitumen provides binding properties while the aggregate provides structural strength.
Conventional bitumen requires heating to achieve suitable workability. Bitumen Emulsion provides an alternative by dispersing bitumen in water, allowing it to be applied under suitable conditions without the need to heat the bitumen to conventional hot-mix temperatures.
This makes Bitumen Emulsion a versatile solution for road maintenance and construction applications, particularly where ease of application, workability, and reduced heating requirements are important.
As per IS 8887:2004, various grades of Cationic Bitumen Emulsion are manufactured for specific road construction and maintenance applications.
RS-1 Bitumen Emulsion is recommended for applications such as tack coating, where rapid breaking and adhesion are required.
RS-2 Bitumen Emulsion is commonly used for surface dressing and grouting applications.
MS Bitumen Emulsion is suitable for applications including road repair, surface dressing, and penetration macadam.
SS-1 Bitumen Emulsion is used for applications such as prime coats, crack sealing, and fog sealing, depending on project requirements.
SS-2 Bitumen Emulsion is suitable for slurry seals, road mixes, and selected prime-coat applications.
Bitumen Emulsions offer several practical advantages for road construction and maintenance:
