Green Mile Infra Pvt. Ltd. introduces RePLAY™, India’s first and only eco-friendly asphalt preservation agent that gained certification from the Central Road Research Institute (CRRI) in April 2010. RePLAY™ is a patented biobased asphalt preservation agent proven to extend the life of asphalt roads by reversing the oxidation of bitumen in the asphalt mix without emitting life-threatening greenhouse gases like CO2.

Shankar Rao, Managing Director of Green Mile Infra explains, “Approximately 90% road pavements in India are asphalted; and overtime, asphalt oxidizes and wears out due to oxygen in air, improper water drainage system and overload. The oxidation leads to brittleness that causes cracking and potholes on the surface. Eventually entire resurfacing is required that puts major financial burden to the concerned authority or the contractor. When we treat the usable surface with RePLAY™, it reverses past oxidation and saves the surface for another three to five years at a fraction of the cost of repaving.”

CRRI conducted field tests on a six-lane toll road in Noida, India in July 2009, allowing eight weeks for RePLAY™ to fully penetrate the asphalt matrix. Twenty-four core samples, 12 unmodified and 12 modified with BioSpan’s patented technology, were collected and analyzed using ASTM International standards. Results from the study proved RePLAY™ “definitely improves the properties of bitumen present in the road” and “much improvement [was] seen in the bituminous mix.”

Developed and manufactured by BioSpan Technologies, Inc. of Missouri, USA, RePLAY™ is carbon negative, safe for the environment and user, and easy to apply. RePLAY™is an alternative to costly repaving that is composed of 88 percent biobased material, a majority of which is soybean oil. Compared to petroleum-based products, RePLAY™ is the most cost-effective solution for asphalt surfaces. Green Mile Infra Pvt. Ltd. is the exclusive master distributor of RePLAY™ in India.

India has the third-largest road network in the world and spends millions of dollars annually on paving thousands of miles of roads. As the CRRI’s report proved, RePLAY™ can extend the life of Indian road surfaces at a fraction of the cost of conventional road maintenance and repaving.
