Earlier in the project we had a weather-related density problem. A heavy rain shower passed through and we had to quit for a while for the road to dry up. Back where we had the shower the mat cooled off pretty quick down to about 100°F. The state density man said we had not achieved density, as he was reading 87 on the cooled mat and we were shooting for 92. So I sent the oscillation roller back, and on just one pass it brought it up to 94.
