Unfortunately, infringement is a common occurrence in the graphic arts. Here are some examples: 1  A licensee re-uses the work beyond the scope of the license, as in the example above where the magazine adapts the illustration for a column logo.  An illustrator makes a painting from a photograph.
Most trucks can carry up to 11 1/2 cubic yards. In the winter, concrete trucks may only be allowed to carry seven or maybe as little as four cubic yards per trip.    A truck that carries that six-cubic yards of concrete in one load can weigh as much as 20 or 30 tons.
If the delivery guy comes i a simple one ton (i.e. Ford F350 of GMC 3500) with a mason dump, the weight will range between 9,000-12,000 pounds. If your driveway is concrete then it should be 4,000 pounds per square inch.This is more then enough to support the weight of the deliver. used to deliver for a nursery i managed, and never cracked a driveway. It was a single-axle Isuzu flatbed, and I used to deliver upwards of 4 tons. I would almost gaurantee your driveway is rebar reinforced, and therefore the truck should be able to pull on, dump and pull off with no poblems.
