Have we talked about chipsealed roads? If not ... they suck..... Here in the USA at least it has been my experience that the "chips" of rock are over applied leaving a very slippery surface on newly "sealed" roads. Once you have seen a few of them, they are recognizable as the entire road bed (at least in the beginning) is extremely uniform in color, but is slippery as hell!!! take care. https://en.wikipedia.org/wiki/Chipseal "Although chip seal is an effective low cost way to repair road, it has some drawbacks. Loose crushed stone is often left on the surface, due to under-application of bitumen or over application of stone. If not removed, this can cause safety and environmental problems such as cracked windshields, loss-of-control crashes (especially for motorcyclists, bicyclists and small trucks), and deposition of foreign material into drainage courses. Therefore, it is very important to sweep the road after the emulsion sets."
