About Krishna Srinivasan, PhD | President

Krishna Srinivasan, Ph.D., is currently the President of Sripath Technologies, providing leadership and strategic guidance across the Sripath Group of Companies. Srinivasan founded Sripath Technologies in 2006 out of recognition of the growing need across the bitumen and asphalt industry for innovative solutions to common obstacles facing industry professionals.

Embracing a back-to-basics approach, he spearheads product development with an eye to solving complex challenges with performance-achieving additives that also have a focus on sustainability. The result is a robust offering of bitumen-enhancing products that place an emphasis on delivering on mix performance requirements rather than relying on the quality of bitumen itself to meet specifications.

Over 25 years of hands-on experience working in the industry roles across paving and roofing prepared Srinivasan to navigate the technologies behind bitumen performance improvement. His unique experience with technical applications and commercial product development helped establish Sripath Technologies, and its subsidiaries, as a global brand recognized for innovative solutions that make asphalt better.

Understanding the different priorities of transportation departments, plant operators, contractors, and suppliers, Srinivasan directs Sripath’s product R&D to address these concerns by developing dosage efficient, cost effective, environmentally friendly products that are backed by performance data. He also remains current with industry trends and activity across the bitumen market including the impact of changes in the crude oil industry on bitumen quality and performance and demand for products that may help lower carbon emissions.

Srinivasan has established a corporate culture of problem solving, industry collaboration, and transparency. He led the company’s public release of its Environmental Product Declarations. He has also established a vast network of researchers and educators around the world to participate in third-party testing and verification of Sripath’s product portfolio.

Srinivasan is a sought-after thought leader, presenter, and lecturer for industry associations, events, and university programs all over the world. Among other credentials, Srinivasan holds Doctor of Philosophy degree in Materials Engineering from Rensselaer Polytechnic Institute.

Polymer Blending: PGXpand Mixing Guidelines

Sripath’s PGXpand® is a unique, highly bitumen-compatible, specially engineered polymer. Used for bitumen modification in both the roofing and paving industries, its effectiveness and cost-saving benefits have been tested and proven since 2015. Incorporating PGXpand into bitumen is an endothermic process, meaning the mixture needs to be heated during the entire blending process to maintain the temperature. Proper [...]

Why Specially Engineered Polymers Are the Right Choice

Polymer Modified Membranes have a long history in the roofing and building materials industries. In addition to improving high temperature properties, they provide superior crack resistance, particularly in cold conditions, where they have a high strain capability to cope with thermal shrinkage stresses. Additionally, they offer superior fatigue resistance and durability over standard bitumen. More recently, polymers have [...]
