2020-12-30 · Asphalt pulverization is more efficient than full asphalt replacement. Again, because the previous asphalt is left in place, you’re skipping many steps which makes for a more efficient process. You can have your hotel parking lot pulverized, graded, and stabilized within a few hours up to a couple days depending on the size of the lot.How does the OCT explain concrete being pulverized,As we examined the WTC-debris sample, we found large chunks of concrete (irregular in shape and size, one was approximately 5cm X 3 cm X 3cm) as well as medium-sized pieces of wall-board (with the binding paper still attached).
