Native Versus Manufactured Asphalt
Native Asphalt Is The Sustainable Choice
The difference between manufactured and native asphalt isn’t just a matter of how they’re made — it’s what they’re actually made of that’s the real difference. The reason is simple: artificially manufacturing a material like native asphalt costs far too much to be practical — it requires enormous amounts of heat and pressure to force bitumen into rocks. That’s why manufactured mixes rely on chemicals to replicate the natural bonding action of native asphalt. And those chemicals matter if you care about the safety and environmental impact of a pavement patch.
Hidden Problems
Long Term Risks With Manufactured Asphalts
The chemical additives in manufactured mixes create a tradeoff between performance and sustainability. (Basically the better the patch, the worse its potential impact on the environment and people’s health.) That’s why so many manufactured patches depend on loopholes like the “storage exemption clause” to get around VOC regulations. That’s also the reason why so many patches aren’t legal in states with high safety standards like Vermont. With manufactured asphalt patches, it’s either performance or sustainability, never both.
Why Native Out-Performs
Performance Without Compromise
Laws regulating VOC’s and other hazardous substances have grown stricter over the last few decades, both in the U.S. and around the world. And this trend is likely to continue as scientists learn more about the long-term impact of chemicals on people’s health and the environment. That’s why forward-thinking decision-makers are choosing RockAsphalt©. Not only is our patching material 100% VOC free, it also contains none of the other chemical additives that manufactured asphalt patches rely on to work. Our naturally-occurring patching material reduces health, environmental, and legal risks — and without any compromise in performance.
