While we have maintained a rock preparation protocol written and updated by many folks over the years, Eva Stüeken wrote this particular protocol summer 2015. It is divided into five sections: cutting rocks with rock saw, pre-crushing rocks into chips, cleaning rock chips, pulverizing rock chips, and decarbonating powders for CNS analysis.
2 - Asphalt Pulverizing. Pulverizing is similar to milling, in that a huge machine drives along the roadway, ripping up existing asphalt. Unlike milling, pulverization is the first stage in reusing asphalt to re-pave the same area. Pulverization leaves several inches of ground-up asphalt where old asphalt paving used to be.
