1 SPECIFICATION AP-S0041 PAVEMENT MARKING MATERIALS AP-S0041 v10 Printed versions of this document are Uncontrolled Issue date: 16/10/2015 Page 1 of 6 [ ] Copyright CSIRO 2015 Editorial Note This version of the SPECIFICATION clarifies requirements for runway, apron & taxiway markings for 0041/6;. 1. SCOPE a) This SPECIFICATION applies to coatings designed to be applied to various pavement surfaces bituminous (asphalt or spray seal) or concrete roads, car parks, airport runways in order to increase the safe use of the pavement. b) Safe use of these surfaces is facilitated through the use of brighter lines to separate traffic (major & minor roads), introduce order (car parks, public spaces) or delineate spaces (roads and airport runways). c) apas is a registered trademark owned by CSIRO and protected under applicable laws. Use of the trademark or the general scheme is prohibited unless prior approval in writing is obtained from CSIRO via the apas Secretariat.

2 2. BACKGROUND a) apas document D001 should be read to obtain a broad overview of the Australian Paint Approval Scheme ( apas ). b) Manufacturers who wish to participate in apas within Australia should consult apas documents D177. c) apas approval to this SPECIFICATION may be gained by compliance with the requirements detailed in this SPECIFICATION and those in document D192. 3. DESCRIPTION & GUIDE FOR USERS General product description a) Pavement markings are used to improve the safe use of roads and other surfaces carrying all manner of traffic, from pedestrians to cyclists to vehicles and planes. These pavements are an important part of the national infrastructure system. b) Historically solvent based paints were used for line marking (alkyd or chlorinated rubber) but in recent time water based coatings (acrylics) have become the dominant pavement marking.

3 This is due to their speed of dry, ability to provide no-pick up properties and a superior ability to adhere to glass beads thereby providing crucial retroreflectivity in wet night conditions. Note A: Glass beads are accredited by apas under SPECIFICATION apas SPECIFICATION AP-S0042. c) A secondary benefit of water borne pavement marking paints is their lower impact on the environment and on human health and safety. d) Thermoplastic markings are also common. These are single component products that can either be applied hot (by extrusion or screed methods) or cold (pre-formed markings). e) In addition to the thermoplastic and water and solvent based paints used, specialty two-pack products are also used and these may be applied by either extrusion or screed methods. f) Cold applied plastic materials are classified by three modes of application i). Class A roller/squeegee applied ii).

4 Class B trowel/screed box applied iii). Class C spray applied two component g) 0041/6 airport markings are typically used on three distinct areas of airports; i). Runway markings for the actual touchdown/take off areas. To maximise slip resistance, glass beads are not used and markings have a degree of self-cleaning properties. ii). Taxiway markings pavement areas that allow the aircraft to move between Runway and Apron. Typically these markings are yellow and similar to standard water borne pavement marking products iii). Apron markings parking areas for planes and equipment and includes airside roads. Markings are typically available in multiple colours white, yellow, red, black some or all of which may have glass beads applied and are equivalent to standard waterbased pavement marking paints. Sub-classes This SPECIFICATION is divided into the following sub-classes; 0041/2 Pavement marking paint, solvent-borne 0041/3 Pavement marking paint, cold applied plastic 0041/4 Pavement marking paint, thermoplastic 0041/5 Pavement marking paint, water-borne 0041/6 Airport runway markings Technical basis of SPECIFICATION This SPECIFICATION is based on the relevant parts of standard AS 4049; 0041/2 AS 0041/3 AS and other relevant state based specifications 0041/4 AS 0041/5 AS 0041/6 No AS equivalent SPECIFICATION AP-S0041 PAVEMENT MARKING MATERIALS AP-S0041 v10 Printed versions of this document are Uncontrolled Issue date: 16/10/2015 Page 2 of 6 [ ] Copyright CSIRO 2015 4.

Binders for 0041/3 cold applied plastics must be essentially cold peroxide cured acrylate based binders. Informative resin characteristics of such a binder are outlined in Table 1 section 0041/3 below. Of primary importance is the compliance with the technical requirements detailed in Table 1 below. Pigmentation Pigments used shall be non-toxic, non-corrosive and lead-free and comply with the requirements of the Uniform Paint Standard. For s0041 /3 all pigments must be inorganic in nature. s0041 /6 White shall have a pigment volume concentration (PVC) not less than 70%. Of primary importance is the compliance with the technical requirements detailed in Table 1 below Volatiles For VOC content restrictions refer Table 1 below and apas document D181.

7 Colour Products approved under this SPECIFICATION are normally available in a limited range of colours refer the manufacturer s data sheet for details.

PRODUCT APPROVAL REQUIREMENTS General The product and its application shall comply with all requirements of apas document D192 during the application process and the life of the approval. General Technical a) The product shall comply with all requirements detailed in Table 1 below including the stated requirements from the relevant part of AS 4049. b) Field testing shall be conducted in addition to laboratory testing as detailed in the relevant part of AS 4049. Field testing on 0041/2, 0041/3 and 0041/5 is only required to be undertaken on the white product colours, due to their lower market volume, are exempt from field testing provided that they are based on the same formulation (specifically the binder system) as the white product.
