Derek it doesn't really matter if it's up hill or down, basically it's where the road has been compressed/worn by the weight of the HGV vehicles pounding along the same piece of road day in day out!! and as most travel in lane one unless overtaking :bow: thats the lane most affected by the "ruts/tram-lines" in most cases they will only replace the worst parts "costs etc" so the bits they don't do become even worse over time, so the whole process starts again!! :bang:
when I'm in my truck, which has a slightly narrower track than the "big boys" it can weave all over and in some areas become quite dangerous
the only thing to do is nearly "straddle" the white line or move entirely into lane two!! it has gotten really bad on the A/M180 hence they are having to replace 7 miles of road!! it's cheaper to do long lengths!! :bang: traffic management wise and plant usage,
BTW if anyone out there has a rough farm track that could do with some A1 hardcore, have a word with the main contractor thats "doing" your local road, to see if you can buy a waggon load of "plainings" it's the best stuff you can get and just needs "rolling" in once spread!! :bow:
