New Asphalt Driveway

I just had my driveway top coated and the asphalt guy told me about a week should be good. Its been really hot here in southwest Virginia, so I felt that the tar below the surface needed more time to cure. I waited two weeks before putting my fifth wheel on it. It weighs 12000 lbs. I used 2x10 material under my wheels. Under the rear axles I used one piece 8 ft long and under the front jacks I used 12x16 inch pieces. The key is to get the support big enough to distribute the lbs/ft the wheels are exerting. With 26,000 lbs I would be worried that the 3/4 plywood would curl up at the edges over time due to weather and allow the weight to become more concentrated. My camper has been sitting about a month and there are no marks where the boards are.
My guy also said to use boards next to the edges, to keep them from breaking down if you go off the edge of the asphalt.
