Doing another 3km of road. I think this is around 15kms in the series. Pulverize, gravel, pave. The province calls another section each year. Miller Group has been doing the pulverizing for us. They started out with a Bomag. There is around 18 inches of pavement seperated by layers of gravel, and soil cement. Slow going. The spec calls for the machine to get 4 inches below the asphalt in order to mix gravel into the rap. Since the machine goes 22 inches at full depth, it's not possible in some spots. Miller brought in a second machine. A wirtgen, . It was able to gain a lot of ground on the Bomag, and turn to meet him on the way back. Sometimes when the machine comes to a crack in the road, and it catches the asphalt just right, it will pull up a huge chunk, and the machine will almost come off the ground. This time it jammed the drum, and shredded the drive belts. Moments later, the Bomag jumps, and the entire wheel assembly cuts off a 6 inch solid steel shaft, dropping the entire left wheel and steering assembly on the ground. Clean break, no sign of rust. Miller was able to get the Wirtgen going for the next morning, and run it until the Bomag was repaired the next day, and we were able to finish the job Friday afternoon. Giving the road a grade in the morning, so they can start staking, start graveling on Wednesday. The goal is around 2000 metric tonnes a day, stock pile enough to pick up low spots when fine grading. Hoping for mostly belly dumps, as there are a lot of wires. The triaxle end dumps always seem to come along where there a wires. Gone are the days when they put a good 6 inch lift of gravel on, it's an average 3 inches, and since the young inspectors have the spec book on their phone now, they are quick to point out that I only get a total of 1/4 inch high, or a 1/4 inch low. Thank you progress.
