The Full Story
CQS-1P – Cationic Quick Set Asphalt Emulsion
Cationic Quick Set Asphalt Emulsion (CQS-1P) is a polymer-modified asphalt emulsion specifically engineered for microsurfacing and specialty slurry seal applications that require enhanced durability and performance. The polymer modification improves cohesion, flexibility, and resistance to rutting, oxidation, and moisture damage while allowing for a rapid cure and return to traffic. CQS-1P produces a dense, durable wearing surface that restores pavement texture, improves skid resistance, seals minor surface defects, and extends pavement life, making it an excellent solution for preventive maintenance on municipal streets, highways, and commercial pavements.
CQS-1HP– Cationic Quick Set Asphalt Emulsion
Polymer Modified Cationic Quick Set Asphalt Emulsion (CQS-1HP) is a high-performance asphalt emulsion specifically engineered for microsurfacing applications where superior durability, rapid curing, and long-term pavement preservation are required. The polymer modification enhances cohesion, flexibility, and aggregate retention, allowing the microsurfacing mix to withstand heavy traffic loads while resisting rutting, oxidation, and moisture damage. Its quick-setting characteristics enable faster opening to traffic, minimizing disruptions while delivering a smooth, durable wearing surface.
CQS-1HP is designed to restore pavement texture, improve skid resistance, correct minor surface irregularities, and seal the pavement against water intrusion. It is an ideal solution for highways, arterial roads, municipal streets, airports, and commercial pavements where extending pavement life and improving ride quality are critical. When properly designed and applied, CQS-1HP provides a cost-effective preventive maintenance treatment that significantly delays the need for more extensive rehabilitation.
