Installation Procedures:
The following are general guidelines to ensure a successful installation of CG System. For each specific project, a construction engineer will provide exact specifications for installation.
Surface Preparations
- As directed by an engineer, repair potholes, cracks greater than 6mm (1/4"), badly damaged or rough pavement that may require milling and the placement of a leveling course.
- Pavement must be free of dirt, water, oil and other foreign materials. Broom or air clean the surface so it is clean and dust-free.
- Apply tack coat uniformly over the prepared asphaltic concrete surface at a residual rate of 0.9 - 1.36 litres/m2 (0.2 - 0.3 gal/yd2) using a calibrated distributor truck, ensuring that the application rate remains constant. The tack shall contain a minimum of 70% solids.
- The tack coat area must be a minimum of 75 mm (3'') wider than the CG System.
Road Surface Condition
- The road must be dry. Do not install CG System during any precipitation.
- The road surface temperature must be between 5°C* (40°F**) and 60°C* (140°F**). On asphalt surfaces less than 24 hours old, the surface temperature should be between 5°C* and 46°C* (40°F** and 110°F**).
CG Placement Method
- Place the CG System while the tack coat is still tacky/broken. Use a mechanical placement tractor or place manually.
- Keep the material flat and wrinkle free. Installation may require hand brooming. For sharp curves, cut edges and fold over in the direction of the placement of asphalt overlay.
- Overlaps must be a minimum 25mm (1'') to ensure a continuous moisture barrier.
Paving Method
- Pave with hot mix overlay.
- Asphalt overlay must be a minimum of 50mm (2'') compacted thickness.
- All of the CG System must be paved over on the day of placement.
Other Important Considerations for Best Results
- Because glass is a skin irritant, we recommend that workers shall wear gloves
- To cut CG System to desired length, lay it over ironworks, roll, and then cut using a sharp utility knife.
- CG System must be applied so that the material lies flat on the road surface with no ripples. Providing sufficient tension during application will eliminate ripples.
- Overlap all end roll joints 75-150 mm (3"-6"). Ensure that the overlaps are shingled in the direction of paving and that these overlaps also receive an application of tack.
- Overlap side joints 25-50 mm (1"-2").
- To maximize product performance, only construction and emergency vehicles shall be allowed to drive on the CG System.
- The above directions are a brief guide to installation. For complete directions, consult with your distributor.
