DY-TMAL-II(A/B) Air Spray Cold Paint Road Marking Machine
There are numerous international standards relating to road marking materials. (Stoffers 2000) lists 14 European standards specifically on road marking materials. ASTM International (ASTM 2011) lists 19 current standards on their web-site relating to pavement marking paints and coatings. In Australia, the Australian Paint Approval Scheme has a specification for road marking paints (APAS 2007) which in turn references the relevant Australian standards. The standard AS4049 has five parts covering the different types of pavement marking materials and performance assessment of them. In addition there are a number of other standards that are relevant such as those for glass beads, for colour and for testing retroreflectivity.
These testing procedures vary from laboratory tests for specific properties through to on-road tests under real traffic. Generally there is a trade-off between control of the test conditions and applicability to the real world use of the product. Having tight control of the test conditions should ensure that the results are accurate, reliable and repeatable but they may not directly reflect the in-service use of the product. Onroad testing, on the other hand, is more closely aligned to the end-use of the product but it is more difficult to control the test conditions and hence the reliability and repeatability of the results may be compromised.
