How Bitumen Derivatives Are Produced & Their Role in Road Construction

1. How Bitumen Derivatives Are Produced & Their Role in Road Construction In the ever-evolving world of infrastructure development, bitumen and bitumen derivatives play a critical role in ensuring durable, safe, and long-lasting roads. With India experiencing massive growth in highway construction, the demand for high-quality bitumen derivatives, such as bitumen emulsion, CRMB, PMB, modified bitumen, and other road construction materials, has skyrocketed. Companies like ITPL—India’s trusted supplier of world-class bitumen solutions—continue to innovate with advanced products like Durapave, Durapave Emulsions, Styrelf, and Indian Oil Modified Bitumen. This blog explains how bitumen derivatives are produced and why they are indispensable in modern road construction. What Are Bitumen Derivatives? Bitumen derivatives are modified or processed forms of base bitumen designed to enhance performance under varying climatic and traffic conditions. These derivatives include: ● Bitumen Emulsion ● Polymer Modified Bitumen (PMB) ● Crumb Rubber Modified Bitumen (CRMB) ● Instant Pothole Repair Mix ● Speciality binders like Styrelf, Durapave, Durapave Emulsis Each derivative is engineered for specific applications such as highways, city roads, pothole repair, resurfacing, waterproofing, and more.

2. How Bitumen Derivatives Are Produced The production of bitumen derivatives involves controlled chemical processes and specialised equipment found in advanced plants like ITPL Bitumen Plant Mathura, Vadodara, Jodhpur, and Rajasthan. Here’s a breakdown: 1. Production of Bitumen Emulsion Bitumen emulsion is a mixture of bitumen, water, and emulsifiers. It is widely used because it can be applied at room temperature, reducing fuel consumption and pollution. Production Process 1. Bitumen is heated to 140–160°C. 2.Water is mixed with an emulsifying agent. 3. Both phases are pumped into a colloid mill. 4.High-speed mechanical shearing produces uniform droplets. 5.The final product is classified as: ○ Rapid Setting Bitumen Emulsion (RS) ○ Slow Setting Bitumen Emulsion (SS) Applications ● Surface dressing ● Fog sealing ● Pothole patching ● Prime coat & tack coat This makes bitumen emulsion highly important for modern roadworks. 2. Production of Polymer Modified Bitumen (PMB) Polymer Modified Bitumen (PMB) is produced by blending base bitumen with polymers like SBS, EVA, or crumb rubber to enhance elasticity, rutting resistance, and durability.

3. Production Steps 1.Base bitumen is heated to 160–180°C. 2.Polymer is slowly introduced. 3.High shear mixing blends bitumen and polymer. 4.Additives enhance stability and bonding. 5.Quality checks ensure grading standards. Benefits ● Better resistance to cracking ● Longer lifespan of highways ● Superior performance in extreme climates ITPL is a leading PMB supplier in North India and South India, delivering reliable and consistent quality. 3. Production of Crumb Rubber Modified Bitumen (CRMB) CRMB is produced by mixing bitumen with crumb rubber obtained from recycled tyres. Manufacturing Process 1.Bitumen is heated. 2.Crumb rubber (0.5–2 mm) is added. 3.The mixture is blended at high temperature. 4.Rubber swells, forming a modified binder. 5.Material is filtered and stored hot. Why CRMB is Popular ● Excellent skid resistance ● Zero waste—environment-friendly ● Ideal for heavy-load roads ITPL is recognized among the top CRMB suppliers in South India and North India. 4. Instant Pothole Repair Mix Production Instant pothole repair materials are engineered blends of:

4. ● Aggregates ● Bitumen derivatives ● Special modifiers They are ready to use, even in wet conditions. Advantages ● Zero heating required ● Quick application ● Long-lasting repairs ● Cost-effective pothole repair price ITPL offers an advanced Instant Pothole Repair Mix designed for rapid urban maintenance. Role of Bitumen Derivatives in Road Construction Bitumen derivatives significantly improve road quality and sustainability. 1. Enhancing Road Durability Products like PMB, CRMB, Styrelf, and Durapave improve resistance to: ● Rutting ● Cracking ● Moisture damage ● Thermal stress They extend pavement life and reduce maintenance costs. 2. Improving Construction Efficiency Using bitumen emulsion, especially rapid-setting and slow-setting emulsions, allows: ● Faster application ● Reduced heating ● Eco-friendly construction ● Better binding and sealing

5. 3. Supporting All-Weather Road Performance Modified bitumen derivatives help roads withstand: ● Heavy rainfall ● Extreme heat ● Snow and freezing conditions This makes them critical for national highways and expressways. 4. Cost-Effective Infrastructure Growth Using derivatives like Durapave and Durapave Emulsions reduces long-term expenses by minimising repairs and extending lifespan.
