I have been wondering how much weight an average 4 thick concrete driveway can support without the fear of damaging it. 10 x 25 x 412 833 cubic feet of HMA.
Is 2 Inches Of Asphalt Enough For A Driveway Asphalt Paving Thickness
The weight-bearing capacity of asphalt is based on the thickness of the material.
. When its time to install a new asphalt driveway for your home you need to know how much weight the material can hold. The bearing capacity - as Ron says is not simply an asphal issue - the width of the pad will have a zone of stress influence that extends down below your thin asphalt layer. Asphalt Mixture typically weighs from 142 to 148 pounds per cubic foot PCF in-place.
For a total of 66000 lb. Just like the thickness of the asphalt the thickness of the aggregate entirely depends on the expect usage of the driveway. To determine the relative concrete thickness divide the total SN of 7 by the SN per inch of 30 for a slab thickness of 23 inches.
The less weight it absorbs the less the weight capacity of the asphalt. The soil that is under the 6 to 8 inches of granular aggregate is also extremely important. It provides a strong enough surface for heavy equipment to work on to apply the top layer.
To get some idea of how much weight should be allowed on your driveway maybe the State load limit is. If your driveway is concrete then it should be 4000 pounds per square inch. The size of the aggregates can affect the thickness of the asphalt pavement.
Residential driveways typically use 2 to 3 inches of asphalt with 3 being suitable for occasional large trucks or heavy equipment. Ranging from 2 ½ to 3 thick each lift is compacted after application by a heavy roller compactor. Use this section as an asphalt thickness calculator.
For heavy duty traffic like trucks loading docks or roadways we recommend a 2 finish layer. You will need to address from a bearing capacity point of view the interaction. In a typical asphalt driveway the thickness of this base aggregate can range form 6 to 8 inches in depth.
Asphalt driveways need to be a minimum of 2 thick and are typically 3 compacted. However the maximum size of the aggregate in open-graded mixes can be up to 80 percent of the layers thickness. This is more then.
For heavily-traveled roads which must bear the constant weight of hundreds of vehicles including heavy trucks passing over it at high speed paving is usually applied in two lifts of 2 ½. Calculate the number of cubic feet to be paved. I have found that most contractors use 2500-3000 psi concrete for driveways.
Remember to convert the thickness to feet by dividing by 12 inches per 1 foot. The binder provides strength coats loose material and plugs voids. BigH Geotechnical 21 Apr 09 2221.
It is obvious a 23. Ford F350 of GMC 3500 with a mason dump the weight will range between 9000-12000 pounds. Normal weight concrete weighs about 4000 lb.
The typical well built driveway will have 2 - 3 of asphalt plus a 4 substrate of gravel. But if the asphalt is too thin the weight isnt distributed and compresses the material right underneath the tire causing it to pull away from the surrounding pavement and develop fatigue cracks. Bearing CapacityPressure of Existing Asphalt.
The truck will weigh approximately. I figure you can calculate the ground pressure psi of your truck but depending on the basesub grade under the concrete its capacity to. If the delivery guy comes i a simple one ton ie.
For most residential driveways 2 to 3 of asphalt is adequate for daily use. A newly constructed surface is done in two layers a 25-inch thick binder with a 15-inch thick top layer. The load-bearing capacity of a particular driveway can be affected by a variety of factors including the soil underneath it the driveways foundation how old it is the moisture content thickness mix of the asphalt and even the temperature.
A residential asphalt driveway holds approximately 8000 pounds. Lightweight concrete weighs about 3000 lb. If a truck is carrying 10 cubic yards then the weight of the concrete is approximately 40000 lb.
The finish course of a parking lot following the binder layer should be a smaller and smoother stone at 15 thick for a total of 3. For example the standard rule is that the thickness of each layer needs to be at least three times greater than the nominal maximum size of the aggregate.
