Petra Oil’s CMS-2h is a high-performance cationic emulsified asphalt specially formulated for cold mix applications requiring enhanced durability and cohesion. Engineered for use in both rural and urban environments, CMS-2h offers superior performance in patching, surface repairs, and maintenance operations where traditional hot mix asphalt is impractical or cost-prohibitive.

As a medium-setting emulsion with a harder base asphalt, CMS-2h provides excellent workability during application while developing rapid cohesion for faster opening to traffic. It is particularly well-suited for use in cooler climates or early spring and late fall conditions where standard emulsions may struggle to cure efficiently.

The “h” in CMS-2h stands for hard, indicating the use of a harder base binder that enhances resistance to deformation and wear. This makes it ideal for high-traffic areas or locations that demand greater structural integrity from cold-applied solutions. Produced in compliance with AASHTO M208 standards, CMS-2h ensures uniformity and quality across all production batches. It bonds well with a wide range of aggregates and delivers consistent performance across various field conditions.
