asphalt mixes with interconnected voids that allow water to flow through the pavement into the stone reservoir. These porous asphalt layers consist of asphalt binder, aggregates, sands, and recycled materials and are much like a dense-graded hot mix asphalt mixture. By limiting the amount of fines, the porous mixture allows for more air voids.

How to calculate axle weights

12/6/2018 · Let’s say the total weight of the body is 5000 lb, and its center of gravity is 28.2 in from the rear axle. Therefore, we can calculate the Center of Gravity from the front axle to be 208 in – 28.2 in = 179.8 in. Step 3: Use the formula to calculate weight on the rear axle; The Weight on the Rear Axle is 5000 x 179.8/208 = 4322 lb.
