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.

Asphalt Durability in Extreme Weather Conditions

As road networks are exposed to increasingly severe weather patterns, the demands placed on asphalt pavements continue to grow. Longer heat waves, heavier rainfall events, wider seasonal temperature swings, and increased traffic loads are all contributing to accelerated pavement deterioration. For agencies and contractors, the challenge is to formulate asphalt mixtures capable of maintaining performance throughout decades of environmental exposure. Achieving greater asphalt durability in [...]

What Are Asphalt Additives in Roofing Systems?

Roofing systems are only as reliable as the materials that are used to manufacture them. In roofing compounds and roofing membrane formulations, asphalt is the base material that has limitations when used on its own. It can soften under heat, become brittle in cold conditions, and struggle to maintain long-term adhesion and flexibility. Asphalt additives are engineered materials that modify bitumen performance, improving how roofing compounds, membranes, and waterproofing layers retain durability [...]

Improving PMB Performance with PGXpand Polymer Modifier

Polymer modification is an essential part of modern asphalt pavement design. As road networks are subjected to heavier traffic volumes, higher axle loads, and increasingly demanding environmental conditions, conventional binders can struggle to provide the durability required for longer service lives. To address these challenges, the asphalt industry has increasingly turned to polymer modified bitumen (PMB) systems to improve pavement performance. Today, polymer modified asphalt is widely used on highways, intersections, and other [...]
