Methods
SURFTREAT Construction Method
Surface treatment construction method using asphalt emulsion
Outline
The SURFTREAT construction method is a preventive maintenance technique that revitalizes aged pavements and those with rough surfaces through surface treatment.
This technique uses STZOL, a modified asphalt emulsion with inorganic fillers, along with STSAND.
Features
- This product is waterproof and weather-resistant, which helps extend the service life of pavements.
- The price is lower than that of a thin-layer overlay, making it more cost-effective.
- Since cold mix application is possible, it is more eco-friendly.
- The product’s optimal texture improves skid resistance.
Applications
- Improving the texture depth of pavements with rough surfaces
- Protecting pavement surfaces (reduction of deterioration and weathering)
- Erasing airport signs
