# I am working on a educational project. Its a building in

### Customer Question

Hi, I am working on a educational project. Its a building in shopping plaza. I have planned to suggest a flex pavement. Base and subbase and HMA on top. however, I want to have a different pavement where we will put the dumpster. I have decided to have the same base and sub base but instead of HMA put a reinforced concrete slab. Is it ok to do that. thanks for your help.

Or I have to design a rigid pavement, if I want to put a reinforcement concrete slab.

That would be fine. Most cities have Standard Details that show concrete pads around dumpster enclosures, due to the heavy weight of the Trash Trucks

What city and state are you near? I should be able to get you a real life detail.

I live in California and Sacramento county, Elk grove City.

After doing my calculations, I calculated
Layers
HMA 0.30 ft
AB 0.30 ft
AS 1.55 ft
Should I put the concrete slab of the same thickness as HMA. If not, how thick the concrete slab. thanks

See the link below to Sacramento County street standards:

Look at Section 4-7 starting on sheet 4-16

This gives general pavement Structural Sections for your area.

Let me know if you have any questions

Our R= 5 and TI= 7
I used this example to calculate flex pavement.

What I figured is
71/2 inches ( Asphalt concrete)
3 inches (AC) on 10 inches AB.
Does above sound about right?, thanks

I will have
0.63 ft ( ASPHALT CONCRETE)
AB 0.30 ft
AS 1.55 ft
SO, the dumpster pavement will be 0.53 ft higher than the rest of the pavement that I have already designed. ( having HMA on the top layer).
Do you think it sounds ok. Thanks
