RAISED PAVEMENT MARKERS Overview

HPS-TCP C1 ROLL

APPLICATION GUIDE

This procedure outlines the recommended steps for the installation of the Stimsonite Model C80 & 980 Raised Pavement Markers with EF Bituminous Marker Adhesive. Storage: Keep materials in dry, protected areas. For maximum results, keep out of direct sunlight. PPE: The following PPE equipment is recommended during the different stages of application. Operators must fully understand the SDS’ (available from www.ennisflintapac.com) prior to works beginning.

Safety Precautions: EF Bituminous Marker Adhesive in its packaged state is not a hazardous material. However, at operating temperature, it is potentially a hazardous product. Applicators and crew must review and understand SDS’ for all products being used prior to application.

EQUIPMENT

Surface prep & layout Installation • Stiff broom • Appropriate PPE • Blower • Compliant Glue Heater • Measuring tape • EF Spot Marker

General Requirements: EF Bituminous Marker Adhesive can be applied on stable, well compacted asphalt or non-bituminous concrete surfaces, such as Portland cement concrete. New substrates should be allowed to age harden or cure for minimum 28 days before installation. The pavement surface must be clean, dry and have had no rainfall for 24hrs prior to installation. Use a wire brush, if necessary, to loosen and remove dirt. Brush or blow clean the location where the marker is to be placed. Pavement surface must be completely free of dirt, debris, moisture, curing compounds and other contaminants that can affect adhesion. Chemical contaminants such as vehicle fluids must be completely removed well in advance using a degreasing solution and power washer, ensuring all residues are removed.

RAISED PAVEMENT MARKERS APPLICATION INSTRUCTIONS Temperature: Ambient temperature for installation should be at least 1.5°C and 5°C above the dew point temperature (and not falling).

Bituminous Adhesive Prep: EF Bituminous Marker Adhesive is a hot melt material packaged as a solid block. Remove the outer carton from the adhesive block and break the material into chunks. Deposit material into thermostatically controlled melter-applicator equipment. Heat the desired quantity of adhesive to the temperature recommended by the manufacturer. Stir the material frequently to ensure even heating. Start-up typically requires 30-50 minutes.

NOTE: Do not overheat the bituminous adhesive.

1. Determine where to locate the marker: Mark the locations of the raised pavement markers with EF Spot marking spray paint (if unit is not fitted with measuring device). When using raised pavement markers to supplement a solid pavement stripe, offset the markers a minimum of 5cm (or your road authority specifications) from the edge of the stripe. When using raised pavement markers to supplement a dashed stripe, locate the marker in the gap in line with the stripe as per your road authorities’ requirements. This permits repainting without affecting the raised pavement markers’ reflectivity.

NOTE: Do not locate markers over joints or cracks in the pavement surface; avoid placing over existing paint, epoxy or thermoplastic. Marker location must be flat (not sitting on any stone peaks).

2. Apply adhesive to pavement: Position melter-applicator over desired marker location and dispense a puddle of adhesive approximately 150mm in diameter.

NOTE: When installing on open-graded friction course, a second dose of adhesive may be required. 3. Place the raised pavement marker: Place the marker onto the adhesive puddle, aligned with existing lines. Press the marker lightly onto the adhesive. The reflective faces must be perpendicular to traffic. Do not allow adhesive to flow onto the reflective face or build up in front of it. IMPORTANT: Marker must be placed onto the adhesive as quickly as possible, preferably within five seconds of adhesive placement.

4. Allow the material to set. Adhesive will set up in approximately 2 minutes. Do not allow any pedestrian or vehicle traffic onto the work area, as any disturbance during the curing process can adversely affect the durability of the product

Common Reasons which may cause Failure:

1. Temperature: Application temperatures greater than 35°C or less than 1.5°C should be avoided.

2. Concrete: New Concrete must have at least 28 days to set / cure prior to any application. It is recommended to mechanically abrade all concrete surfaces before application, by high-pressure water blasting, milling, mechanical surface grinding, shot blasting or a combination of techniques. Moisture content within the concrete must be below 6% before application.

3. New Asphalt: Application on freshly laid asphalt roads is not recommended. A 28-day curing period is recommended to rid the surface of contaminants and excess bituminous oil. In cases where it is unavoidable, risk of adhesion failure may be reduced by blasting the surface with high pressure water and allowing thorough drying before any works are carried out. Moisture content within the surface must be below 6% before application.
