Doing the runway ends first, makes good sense to keep dust out of the power plants. ..googling, I found reason to advice airport and scenery modellers of these: http://en.wikipedia.org/wiki/Tarmac http://en.wikipedia.org/wiki/Macadam http://en.wikipedia.org/wiki/Chipseal http://en.wikipedia.org/wiki/Dirt_road http://en.wikipedia.org/wiki/Gravel_road ...and of "tar" and "asphalt" ... ;o) http://en.wikipedia.org/wiki/Bitumen http://en.wikipedia.org/wiki/Asphalt_concrete ..what I didn't find, was info on salting dirt roads in the summer to bind dust, AFAIR, this was done after grading it, and in a dry coupla weeks, the road surface would harden and pick up a blue sheen from the tire rubber deposited onto it. This wasn't weatherproof and was lost in the first day of rain, which usually also added pot holes, requiring a new grading pass every 6 or so weeks, so it was "asphalted" ;o) about 40years ago. ..http://en.wikipedia.org/wiki/Washboarding is also relevant to landing gear modeling, but isn't quite understood by the RL road engineers either. -- ..med vennlig hilsen = with Kind Regards from Arnt Karlsen ...with a number of polar bear hunters in his ancestry...
