how much can a tri-axle dump hold?

    I don't know much about heavy trucks, but here's the thing.

    I have a client that is looking at getting at least 25 yards of 2"-4" river rock installed. I'm guessing about a ton per yard in weight. This is at a commercial location with a tight 'L' entrance with a large sign at the turn of the 'L' between the building. Because of this a semi couldn't get to the back where the gravel could be dumped.

    I know a truck has to be licensed for weight, but my question is, can I get that kind of capacity in a regular dump, or do I need to work up pricing for two trips?

    Here's a dated pic of the location, you can't see it, but where the tree at the front corner of the building is, there is a wrap around wrought iron handicap hand rail. There's right at 8' of width between the sign and hand rail.

    The trucks we contract will haul ~ 22t. You will most likely run out of volume before weight on them, when dealing with river rock. I just put 3-6" filter rock in a ditch for a customer and used 30t. It was one big truck an one single axel. The volume on the big truck was 16 yard box. These are large, full size dumps. Hope that helped.

    Well I would be concern about the weight of the truck on the black top or parking lot.

    That much rock on a triaxle will rut the parking lot most likely.

    This. I would split into two trips make sure no damage is caused by the weight.

    There are a lot of variables in what a truck can legally haul. My triaxle is legally maxed out at 14 ton. Its a heavy truck with a demo body. The added weight reduces payload. I would bid two trips. If you rut the parking lot, that is a truly shitty paving job. However if you run off the edge of the parking lot, that can cause a problem. I would lay 1" plywood at the transition from parking lot to dirt (if that applies) so you don't damage the edge of the parking lot. For added safety, have the material dropped as early in the morning as possible before the asphalt gets warm.

    I've never even thought about rutting up a parking lot. Cracking a concrete driveway at some of these cheap houses, yeah. But rutting a parking lot is a new one to me..

    Seen it done and been around when it has been done with black top. Last week a skid steer with load of bricks cracked a drive. So always on my mind.

    I suppose 70,000 lbs can damage a parking lot but the asphalt wasn't very good to begin with if it happens. Or you have made multiple trips over it in 100 degree heat.

    thanks for the answers guys!! I left the property owner under the impression that it won't be able to be delivered in one load. The quarry won't deliver themselves anything under 20 ton. Now I need to see if the 20 ton delivered is something they would split between trucks or if that was only for a semi.
