OPTIMISATION OF PAINT AND GLASS BEAD APPLICATION RATES

The objectives of this project were to identify the optimum application rates for road marking paint and glass beads, in relation to outright performance and cost-effectiveness, and to provide appropriate recommendations. The project involved the use of one solvent-borne paint and one water-borne paint, and all testing was carried out on a dense graded asphalt surface. Essentially 2 or 3 paint film thicknesses and glass bead application rates were used, and the wear of markings monitored. All application and assessments were carried out in accordance with departmental test procedures. Water-borne paints are more cost-effective than solvent-borne paints, as they provide significantly greater durability and retroreflectivity than solvent-borne paints, at the recommended application rates. The most cost-effective markings based on water-borne paint, are those with a paint wet film thickness of 300 micrometres, and a glass bead application rate of 210 g/m2. The most cost-effective markings based on solvent-borne paint, are those with a paint wet film thickness of 400 micrometres, and a glass bead application rate of 250 g/m2. The estimated net present value of benefits (based on 1994/95 values) achieved by replacement of the solvent-borne paint by water-borne paint, in South Australia, is $3,500,000 for a period of ten years from full implementation. The less tangible benefits will include significantly improved night and day visibility of markings, which will improve road safety. (a)
