The aggregate from the weigh hopper is dropped into the mixer (pug mill) and drymixed for 6 to 10 seconds. The liquid asphalt is then dropped into the pug mill where it is mixed for an additional period of time. At older plants, RAP typically is conveyed directly to the pug mill from storage hoppers and combined with the hot aggregate.

· The hopper has an auger to churn the concrete and keep it liquid, ... Many pumps can pump 30 to 100 cubic metres of concrete per hour. And this quick, precise placement method also ensures a quality pour. The setup time for concrete pumps is also very fast—arriving on site and pumping concrete within the hour.

· Concrete never stops curing, with its strength only growing through time. It becomes safe to walk on 23 days after pouring, but shouldn't be considered "set" until it has set for at least a week. After initial placement, concrete increases in compressive strength very quickly for 37 days, then gradually for the next 3 weeks.
