Same here in Lincolnshire. We have usual numerous annual surface dressing events, no doubt sponsored by Autoglass. My work colleague had his windscreen cracked by a lorry going silly speeds in the opposite carriageway on the A15. There was a section on my commute to work on the A46. So I chose to drive a different back road route for a couple of weeks to save my paintwork and windscreen. Another friend got her windscreen cracked on the same A46 section. It is all well and good the contractors putting up 20 mph signs. However, even when the majority adhere to them, it doesn't stop the odd selfish / ignorant idiot driving at warp speed and overtaking you / or comming the other way and taking out your windscreen. I can think of no good reason why they cannot clean up the excess chippings a few hours after they have laid them, instead of the usual practice of leaving them for 2-odd weeks and letting the traffic sweep them up. The whole exercise is almost futile anyhow as it lasts less than a year on heavily used roads. They should amas a few years budget (by spending in advance or saving unused budget from previous years) and do a proper resurfacing job with decent tarmac. However, local government financing being what it is, it probably is not possible to implement as they seem to have the "use it or lose it" bugetting model. Surface dressing is false economy IMHO; It would be cheaper and better in the long term to do it properly once every 10 years than a hopeless effort every 2.
