Block Paving Storage Area
Block Paving Storage Area
(OP)
We are designing a block paving storage area. The existing ground is reclaimed land which is sand 6m deep with underlying silt.
The requirement is for a storage area which will hold fabricated units up to 100 tonne and containers. Axle loads are generally 10 tonne per axle, but the heaviest loadings may be those from top loading forklifts carrying 40 foot containers.
The plan is to excavate to formation in the existing sand, compact and then lay an unreinforced concrete slab. Block pavers will be laid on a 50mm coarse sand bed.
Any recommendations on the slab thickness? or advice in general on the proposal?

There are many fine examples in India, Maylasia and othe countries with high capacity ports.
The ICPI (Interlocking Concrete Paver Institute) and several European organizations have very good design guides for heavily loaded applications on marginal/moist soil conditions.

concretemasonary, I have seen a port carried out as you say with concrete blocks laid on sand on a compacted crushed rock sub-base - this was Fishguard (spelling?) in Wales. I have also worked on a Port in West Africa where we used concrete blocks on sand on a cement stabilised sub-base. I think it is not unusual to use CSM or concrete for this purpose.

In the absence of a solid base, I've used non-woven geotextile to provide a more stabilized base. I've also used lime with some clay materials.

The choice of a 100 mm paver is good. If available locally, the "zig-zag" paver shape usually is better than the rectangular brick shape. Also, the "herringbone" pattern gives better stability, especially if you have repeated turning traffic patterns.
You may want to check with the local suppliers about shape availability. Also your area may or may not use more automated setting equipment. The large Asia projects for ship containers I have seen were usually hand set.

Does anyone has a little program to calculate rigid pavements?
I've got Elsym5 to calculate flexible pavements, however to calculate rigid pavements I need a program or a excel file.

Thank you for the answer. I've got to design a industrial pavement road that will be loaded with heavy traffic.
Do you think the PCA program can help me to solve the problem?

There are several layered pavement programs available, but, I haven't used them. I have an excellent mathematical analysis listing that's a little 'hairy' and haven't had an opportunity to code it into Delphi... I can try to dig up link if you like.

However if you can help me with your math analysis I'd enjoy.
