The following are general guidelines to ensure a successful

installation of CG50 and CG100. 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

/

4in.**), 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.

Road Surface Condition

• The road must be dry. Do not install CG50 or CG100

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 shall 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 (1in.) to ensure

a continuous moisture barrier.

Paving Method

1. Pave with hot mix overlay.

2.Asphalt overlay must be a minimum of 50mm (2in.)

compacted thickness.

3.All of the CG system must be paved over on the day

of placement.

Important Issues

1. Because glass is a skin irritant, workers shall wear gloves

while handling CG.

2.To cut CG to the desired length, lay it over ironworks,

roll and then cut using a sharp utility knife.

3.CG must be applied so that the material lies flat on the

road surface with no ripples. Providing sufficient tension

during application will eliminate ripples.

4.Overlap all end roll joints 75–150mm (3 in.– 6 in.). Ensure

that the overlaps are shingled in the direction of paving

and that these overlaps also receive an application of tack.

5. Overlap longitudinal joints 25–50mm (1in.–2in.).

6.To maximize product performance, only construction and

emergency vehicles shall be allowed to drive on the CG.

These directions are a brief guide to installation. For complete

directions, consult with your CG distributor.
