PAVEMENT MARKING STANDARD SPECIFICATION ROADWORKS DoI REFERENCE TEXT December 2015 Page 104 15.5 ROAD MARKING PAINT WITNESS POINT Road marking paint: Approved water based white road marking paint conforming to APAS 0041/5 and suitable for application by spray equipment in accordance with Test Method AS/NZS 1580.205.4 to asphalt and bituminous seal road surfaces and for use with Intermix drop-on spherical glass beads. Australian Paint Approvals Scheme (APAS) Specifications: For paint types identified by an APAS specification code, conform to the specification represented by that code. Witness Point - Submit a 'Certificate of Compliance' of the paint with the relevant Australian Standards or APAS specification. 15.6 THERMOPLASTIC MATERIALS Thermoplastic road marking material must consist of aggregate, pigment, binder, glass beads and extenders, capable of being softened by heating and hardened by cooling. Thermoplastic road marking materials must comply with AS 4049.2. 15.6.1 Audio Tactile Markings Thermoplastic used for audio tactile pavement markings must comply with AS 4049.2 but modified as follows: Softening Point: When determined in accordance with AS 2341.18 the softening point shall be not less than 95 C. Cold Flow: When determined in accordance with AS 4049.2:2005 Appendix I Determination of flow resistance - the cold flow shall be no more than 5% at 40 C. Skid Resistance: When tested in accordance with AS 4049.2:2005 Appendix K Field tests for thermoplastic pavement marking material and Appendix L Field determination of skid resistance (wet pendulum method) - at any time up to 3,000,000 vehicle passes, the skid resistance value of beaded unprofiled base material must be not less than 50. Retro-reflectivity: Mix glass beads to AS/NZS 2009 Type C into the thermoplastic material at a rate of not less than 30% by mass prior to application. 15.7 COLD APPLIED THERMOPLASTIC MATERIALS 15.7.1 Standards AS 4049.2 Paints and related materials Pavement marking materials - Part 2: Thermoplastic pavement marking materials For use with surface applied glass beads AS 4049.4 Paints and related materials Pavement marking materials Part 4: High performance pavement marking systems AP-S0041/3 Pavement marking materials cold applied plastic AP-S0042 Glass beads for use in pavement marking paints 15.7.2 Materials Witness Point Generally: A two part Poly Methyl Methacrylate resin based pavement marking material that complies with the requirements for colour, luminance and bead content of AS 4049.2, and which complies with AS 4049.4, sprayed or screeded onto the pavement, containing premixed glass beads, with additional drop-on beads being added during application, conforming with the following requirements of AS 4049.2: Clause 5.1 Colour, Clause 5.2 - Luminance and Clause 7 - Field Testing. The material shall have a maximum no-pick-up time of 60 minutes. Witness Point - Provide evidence that all proprietary products such as epoxy or plastic products have demonstrated satisfactory field performance for a period of at least three (3) years. 15.7.3 Application Witness Point Application is to be in accordance with the Manufacturers Specification. Witness Point - Provide evidence that it has been applied in accordance with the Manufacturers instructions. The area to be marked is to be dry and free of dirt, gravel, oil and other loose or foreign material to ensure the best possible adhesion of new material. Remove existing paint or other material which is flaking or chipped. Cleaning may be carried out by brooming, blowing or washing. Use a tack coat or primer material for surface or other conditions requiring it in accordance with the Manufacturers Specification. Apply by spraying, screeding, trowelling or extrusion methods, including application of glass beads and anti-skid material, in a single uniform layer. For longitudinal lines and transverse markings, apply material at a rate to achieve a minimum
