New Asphalt Driveway - How Soon to Drive Tractor over it?

Ain’t Science Great!:laughing:

Just don’t let any one hundred pound ladies wearing high heels walk on the asphault!

Consider Newtons third law. For every action there is an equal and opposite reaction. Therefore if you have 35psi of air in your front tires, the maximum pressure per square inch applied to the asphalt is 35psi. Now that pressure is applied over many square inches. That is why the tire patch increases as you add weight to the loader. If you have a 3500# load on the front axle no square inch of the front tire will exceed 35psi.

I知 hoping this was said as a joke. You need to put a smiley face at the end so people know.

It's not a joke, for most tires this principle holds roughly true - the ground pressure is roughly equal to tire inflation pressure. On a car with nice flexible tires, it's very much true. On a tractor with turf tires, it's pretty much true. When you get into stiffer tires like R1 and R4s, with funky lug patterns, this is where things change, and the tire lugs/bars definitely do exert more ground pressure than the tire inflation pressure.

In essence, other than the structural capacity of the tire rubber and sidewalls, this principle is true.

Looks great and I personally like the tree, it adds interesting detail. Those here that mentioned about driving on newly-surfaced roads, that's a whole other animal...they use a different mix and apply more of it compared to residential asphalt surfacing. Also, it's way more expensive. We had our driveways and apron resurfaced a number of years back, we were offered the commercial application...I was like no thank you, I don't need to go into debt over a driveway.

If that asphalt is not useable in 8 hours , it is garbage . Good mix proper compaction before and after . Looks to me like it was done right .

Since 1686 every engineer and scientist in the world have agreed with Newtons law. If you feel that they are wrong...

How is it that Jeff9366 overlooked the whole topic of tire air pressure in his post on TRACTOR WEIGHT as ONE CRITERION IN TRACTOR SELECTION?
:laughing:

First not a scientist. Been years since I was in school, well what is called school. If the pressure per square inch is limited to roughly the air pressure in the tire itself...so if there is say 100 square inches of tire on the ground the pressure would be the same pressure as if the same load was on narrower tires and the square inches of tire on the ground was say only 50 inches the pressure would be the same? If that is true then why do we need wide tires on heavy loads? Of can the pressure still be the same and the load be more?

I hope you are joking with these questions, can't really tell. ................................

It's a mixture. The first paragraph is absolutely true. One of my grade school teachers really made that statement about centrifugal force and gravity.

The following three points following that were a lighthearted poke at the thought that application of Newton's third law would have anything to do with the load the tires imposed upon the driveway. Note the smiley after "helium balloon".

What is road mix I hear that term and would love an explanation

Has anyone got out and looked at the road to see if it is still perfectly smooth no imperfections? Once that is done would you want your driveway to look like what you see
