I must be grasping at straws here. I need to save my client some money by using as much overlay as possible, over a car park. The existing pavement has an area where both concrete and asphalt exists (used to be an underground LPG tank there under a huge concrete slab. They excavated the LPG tank...

Can the dolly transfer any weight? I mean in my case, the prime mover tows a dolly that looks like a mini semi trailer via a gooseneck, which in turn tows a semi-trailer via a gooseneck.

I'm a bit confused. the M1000 HETS looks similar to the commercial trailer in my case. How does it transfer load to the tractor when mine can't.

Material will be crushed rock and concrete. Tank weighs 60 tons. Not sure about the truck. The trailer is indirectly connect to the prime mover via a dolly converter. So I'm not sure if any of the tank's weight can be transferred to the prime mover. The truck will start from 0 speed, so...

This is somewhat related to another thread of mine. Basically I want a truck to climb a 1 in 3 incline. How can I determine whether it has enough power to do that or not? I don't even know where to start. I'm a civil engineer, and an undergraduate at that. This is such a special project that...

I have to design testing ramp for military vehicles, but they use a civilian low loader for their tank transporters. You can see the exact configuration here: http://www.defence.gov.au/jlc/Documents/Cleaning%20Manual/91.pdf Most other vehicles that will drive on this road are obviously of...

so I'm raising the surface by 0 - 200mm over a large area. Using all asphalt is too expensive, do you think I can just chip off a layer of existing asphalt, throw some crushed rocks on top, then put new asphalt down? I'm asking because I seem to recall that crushed rock only goes beneath asphalt...

What is the maximum crossfall for buses, assuming very low speed (<20km/h)?

I would document the client's decision. Run some aquaplaning checks on 1% and be done with it.

I'm a civil engineer, but this issue may be relevant to automotive engineering, so I want to hear your opinion on it. I have to design a road for a large semi-trailer. In my simulations, the back end of the semi-trailer always snags the ground in sags. There are 4 rear axles and no front...
