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.

Video: How Should RAP Be Managed at a Mix Plant?

TRANSCRIPT FROM VIDEO: To use high amounts of Reclaimed Asphalt Pavement along with an effective rejuvenator, plant and quality managers need to make changes to how they process their materials.   While RAP has historically been perceived as a waste product, plants should treat it with the same care given to other input raw materials. Fractionated and homogenized [...]

Video: How Do High-RAP Mixes Dosed with Rejuvenators Age?

TRANSCRIPT FROM VIDEO: Balanced mix design that incorporates Reclaimed Asphalt Pavement dosed with a rejuvenator should consider adherence to performance properties both now and many years after wear and weathering. Testing should include an evaluation of how the aging process impacts these mixes to ensure durability and long-term performance.   Simulated aging tests for measures of the Cracking [...]

Video: High-RAP Mix Case Study: Lab Test of 100% RAP Dosed with ReLIXER

TRANSCRIPT FROM VIDEO: While high-RAP mixes include any mix with more than 25% Reclaimed Asphalt Pavement, some departments of transportation are looking to push the envelope on RAP usage. When using an effective rejuvenator, RAP usage of up to 100% is possible while maintaining performance specifications.   A field trial demonstrated the viability of 100% RAP mixes with [...]

Understanding Polymer Modified Bitumen (PMBs) – Frequently Asked Questions

Paved roadways have been around since ancient Babylonian civilizations began blending asphalt with gravel to accommodate travelers and merchants. In more modern times, roads constructed from asphalt, or bitumen, appeared in the late 1700s as chemists started to better understand the binding qualities of natural asphalt in surface performance.    Fast forward to today, and the Earth is [...]
