Concrete driveway loads
Concrete driveway loads
(OP)
Assumption: A standard concrete slab mix is 3500 psi, has no reinforcement.
Q: Could a heavy vehicle (13,000 lbs rear wheel axle rating)cause hairline cracking of a fresh (6 Month)driveway? Or would this more likely be attributed to a poor subbase?

my brother parks his triaxle dump truck on a 2500 lb mix with no problem

If you have noticed a hairline (non-structural)crack in your concrete it will most probably be due to drying shrinkage. If you haven't divided the slab into bays with movement joints or used a slip membrane below then it will shrink over the first 6 months and tensile stresses will develop causing subsequent hairline cracking.

I would like to explain driveways reinforcement again.
In a slab you can face to two possible cracks: Structural and Non-structural.
If you do not design correctly the thickness and other parameters as joint spaces or subbase movement cause structural cracks in the slabs.
I did not design any slabs but, casted millions of sqm at the job sites.
If you believe my experience I will share my pratical information at next mail.
Please just have a look the coming notification.
