Having a good dump man is half the battle. Someone who reads grades, understands slope, and has a good understanding of how each truck driver spreads. Around here the grader never spreads sandstone, or sub base because the government spec wants the material tramped by the tracks of a dozer. The dozer can't touch crushed material because they don't want it tramped. We do 18 inches of 3 inch minus , or a 5 inch crushed sandstone that has passed spec. Because of the slope of the ditch, we do a 9 inch lift, step in in order to match slope and stake it for another 9 inches or the finished grade of the full 18 inches. Go back and string line and compact for spec. Step in again for slope, and stake for 6 inches of inch and a quarter minus. Then go back again, replace any loose stakes, and instead of just having them 25 meters apart, put more in between at 12.5 meters. String line, and compact for spec again. Pull the center line stakes, lightly float the road back and forth, compact, 3 lifts of asphalt, pull the shoulder stakes, blend the slope from sub base to finished shoulder, place inch and a quarter minus from edge of pave to finished shoulder, compact, guardrail, signs, paint lines, go home. I only dump material in a pile if the road is really wide.
