Road Markings & Markers Method Statement

Below is a brief method statement for road markings and road signs. The method will ensure the quality of work in accordance with the contract requirements and applicable local standards.

Following this method statement will also ensure that all quality assurance/ control activities are happening in a systematic manner.

Arrange following materials and tools before start of the road markings works.

• Warning tapes
• Temporary signs
• Safety Barriers
• Traffic Cones
• Grade Stakes
• Road marking Paints (White and Yellow)
• Soap Solution ( not detergent)
• Cleaning Cloths, Roller Brushes, Paint Brushes, Permanent Tapes, fine emery papers, etc.

Plant & Equipment for Road Markings Activity

The major equipment for this construction works includes, but are not limited to the followings;

• Pavement Marking Equipment
• Process Monitoring Equipment
  1. Portable environmental measuring devices for temperature & humidity
  2. Paint application rate computers
  3. Electronic scales / bead bucket and stop watch for glass bead application rate
  4. Applicator speedometers, calibrated over range of applicator speeds
  5. Paint pressure and / or hydraulic/air pressure gauges
  6. Wet film gauges
  7. Bead application comparison plates.
• Post-Application Measuring Equipment: Non-destructive eddy current device such as the Elcometer and steel test plates for dry film thickness. Retro reflectometers & Skid resistance testers.

Occupational Health & Safety Requirements During Road Marking Works

Implement the requirements of road works project safety plan procedures strictly.

Possible hazards may arise from filling activities, take the necessary safety measures to prevent accident or injury at all times. This may include barriers, warning tape/ net, signage, watchman, and
proper lighting.

If there are existing services, obtain the necessary work permits and provide safety equipment prior to the activity commencement.

HSE officer will enforce that site personnel are using Personal Protective Equipment (such as Respiratory mask, Safety Shoes, Face mask, Hard hats,,, etc.) at all times during construction activities.

Prior to the commencement of any activities, the workforce will receive an induction talk on the project site safety requirements. This induction talk will include both activity safety issues, as well as general safety requirements.

Make sure that all plant and equipment are having back-up alarms, lights, and all other applicable safety devices.

Maintain proper access to the work area throughout the working period.

Road Markings Procedure Steps

Before the start of road lining work the Surveyor will locate and mark all center lines, width and length for all types of white / yellow lines on road.

Prepare the surfaces by removing effervescence, chalk, dust, dirt, grease, oil and release agent. Make sure the roughening of the surface with fine emery paper to remove glaze.

The surveyor will locate and mark all main Outlines, Spots and coordinates for every type of road markings and signs. These outlines will be clearly marked using chalk lines and tapes.

Carefully mix and prepare paint materials in accordance with manufacture direction. Use suitable thinner approved by Paint manufacture and only within recommended limits.

Using roller brush, apply a single coating of white color road marking paint on to the yellow rubber surface evenly.

While road line painting, protect adjacent areas and installations by using masking tape or take any other precautionary measure.

When the white color paint becomes dry, apply evenly a coat of yellow road marking paint on the top of the white surfaces.

Finally once the single coat of yellow Paint becomes dry, apply another final coat of yellow road markings and let it to dry.

Apply paint to an even and fine texture, leave no evidence of rolling such as laps, irregularity in texture, skid marks.

Apply additional coat where under coats, stain or other condition is visible in final coat.

Method Statement for Road Markers

Road markers are separate raised metallic or plastic or ceramic units fixed on the road surface for the purpose of directing traffic according to the required lane.

Apply a mass of material that is approximately three-quarters the size of the stud to the hole.

When the typical stud application method is used, a stud is centered 2.54cm (1 inch) to 5.08cm (2 inches) above the road surface and dropped onto the hole. With finger pressure only, the stud is pushed down to a point where a slight bead.

The entire stud bottom should be supported by adhesive, and there should be adhesive surrounding the stud. Be careful not to have excessive adhesive in front of the stud.

Make sure that the surface on which the lines or reflectors are installing, they are clean and free from old markers or lines. Make sure the surface is dry and free from any oils or lubricants.

After ensuring the cleanliness of the surface and its suitability for placing lines or markers. Review the consistence of the surface such that it must not be disintegrated. Ensure that there are no large cracks or any other defects which may minimize stability of the lines or reflectors on it.

Contractor must supply and install all the work parts shown on the drawings of the special specifications with the dimensions, machines and tools required for completing the works according to requirements.

Fixing of Road Markers

Fix all the road markers at the locations on the drawings such that the distance between markers must not be less than half (0.5) meter and not more than six (6) meters.

For fixing units, holes are made on the asphalt after cleaning the whole surface, by a driller, the diameter of the hole must be more than the reflector’s stud diameter by about two (2) to four (4) millimeters, and with a depth of more than the length of the reflector stud by about two (2) to four (4) millimeters.

After that clean and fill the hole with the adhesive according to manufacturer’s recommendation.

Fix the reflectors by inserting the fixing shaft to a depth of six (6) centimeters on the asphalt surface. The fixing stud must be deformed or grooved to resist extraction.

Use of Bituminous Adhesives

Fix the markers by using an adhesive material composed of bituminous. Manually mix the compound or epoxy resin. The bituminous adhesive must not contain rubber polymer, since the high temperature at cohesion may lead to the adhesive disintegration.

The compound must be tested and used according to the manufacturer’s recommendation. Adhesive must be suitable for application in temperatures range between zero (0°C) to fifty eight (85°C) degrees Celsius.

Equipment installing markers and lines must either be units mounted on trucks or motor equipped units that the worker rides or manually driven equipment according to the type of the markers or lines required.

Motorized units which are rode by the worker must be capable of working in a speed not less than eight (8) Kilometer per hour, but the manual equipment must be capable of maneuvering in such a way enough for making the axes lines, lane lines, and side lines, and drawing triangular pieces, turning lines, pedestrian lines, parking lines, arrows, symbols and terms.

All shapes and lines must be in compliance with the specifications.
