The new markings are not only safer, "They're also considerably cheaper and save quite a bit of time." As part of the trial, VicRoads is testing four different grades of paint for longevity, reﬂectivity and skid resistance. Boyd says low-grade paint only lasts two-to-three months before it has to be redone, which can be costly on long-term projects such as the M80 trial. "There's a high-grade yellow paint that lasts between six and 12 months, and when we reinstate it with glass beads it can last from three to ﬁve years,” he says. While the differences in the cost of the paints are often small, Boyd says the savings in time and money are far greater. "Contractors don't have to spend night after night grinding or blasting over existing markings," he adds. TEST DRIVE When the trial wraps up in mid-2013, VicRoads will have amassed a lot of evidence about the performance of the yellow lines. But the RIAA’s Dean Crutchﬁeld is It's been so successful in terms of saving time and money, but also making it enormously safer for drivers to easily identify where they need to drive. It's a no-brainer. one of many millions of motorists who've experienced it ﬁrsthand. He was "very impressed" when he drove over it one wet Friday night before a long weekend. "It's working really well and I know VicRoads is getting good numbers on their retro readings, which means the lines are bright at night,” says Crutchﬁeld. "They should be congratulated for trying something different on one of the busiest roads in the city." Road authorities in other states have shown interest in the trial and VicRoads is happy to share what its learned throughout the process. It presented a paper on some of its results to a recent RIAA conference in New South Wales and Boyd says there's no need to wait until the trial is over to beneﬁt. "It's been in place long enough and has undergone sufﬁcient analysis to demonstrate it's a worthwhile proposal. I would suggest it become standard practice in road-work zones across Australia. "It's been so successful in ter ms of saving time and money, but also making it enormously safer for drivers to easily identify where they need to drive. It's a no- brainer,” says Boyd. ••• CONTINUE THE CONVERSATION Have your say on this story. Go to http://goo.gl/h7iY3 to comment on this article.
