In the example, our order is for 150 cubic yards of concrete with each truck carrying 10 cubic yards and unloading every 10 minutes. We further estimate that the travel time to the job is 20 minutes and that your plant takes 5 minutes to load a truck. Divers will check the load after batching, which takes 5 minutes.
1 Some companies will just use a round figure of 3000 pounds per cubic yard. 2  Not all trucks will hold 20 tons per load. 3  Again, find out from the dealer how big a truck load is. 4  The size of the truck will not change the calculations any, but it will help determine how many loads you need for your project.
