How to Calculate Asphalt Tonnage – 5 Simple Steps
- Step 1: Measure your pathway.
- Step 2: Convert the measurements to feet.
- Step 3: Multiply the measurements to cubic feet.
- Step 4: Multiply the weight density of asphalt with the volume figure.
- Step 5: Covert the amount to tons.
How thick should asphalt be?
Residential driveways typically use 2 to 3 inches of asphalt with 3 being suitable for occasional large trucks or heavy equipment. Underneath the asphalt you should have 6 to 8 inches of granular base aggregate. Underneath this you have soil.
Can you put asphalt over dirt?
Asphalt is still one of the more common driveway overlays, even over dirt. While it usually requires professional installation, it provides a durable, level driveway surface, even on grades. Unlike gravel or RAP, it cannot be laid directly to dirt surfaces.
Both of the types of asphalt are great, it simply depends on the needs of the homeowner. If a homeowner needs a heavier weight load, then the 41B asphalt type should be selected. For ordinary driveway use, then the 41A is the choice that most homeowners choose.
Can you put asphalt over concrete?
If the question is “CAN I lay asphalt over concrete?” then the answer is “Yes.” This is absolutely possible if elevations allow for it, and we’re happy to lay asphalt driveways over concrete if that’s what you want. It’s also the cheaper option since heavy equipment is required to dig up an existing concrete slab.
Can you lay asphalt over sand?
Some types of permeable pavement such as loose gravel, interlocking concrete pavers, porous concrete, and porous asphalt are unsuitable for use on sand. This is because, among other things, they are not rooted in the soil at all.
Is blacktop the same as asphalt?
The materials that are used to make blacktop and asphalt are the same. Both are made from two ingredients: bitumen and crushed stone. The difference lies in how those ingredients are combined to make the final product.
Does concrete last longer than asphalt?
Overall, asphalt is less durable than concrete. With proper maintenance, it can last 30 years. Alternatively, concrete provides a sturdy, long-lasting option and can last homeowners 50+ years with occasional repairs and degreasing.
Will rain hurt a new asphalt driveway?
When rain comes into contact with fresh asphalt, it causes the oil to rise to the surface which can affect the curing time and the finished product. If asphalt is paved while it’s raining, it can reduce the overall quality of the asphalt. Rain also jeopardizes the stability of the subsoil.
How long does it take for asphalt to harden?
Since asphalt needs time to harden and cure, usually 6-12 months, your parking lot or driveway will remain soft and pliable until then. You may walk on the new pavement immediately, but keep automobile traffic off of it for at least 3 full days and longer in hotter temperatures.
Are pavers more expensive than asphalt?
Asphalt is cheaper than pavers in up-front installation costs. Pavers are lower maintenance and generally have a longer lifespan. You have more design and visual variety options with pavers.
Concrete driveways normally last longer than asphalt.
In general, if installed properly in a suitable climate and maintained regularly, your concrete driveway should last 30 to 40 years, while an asphalt driveway is generally good for 20 to 30 years.
Is asphalt the same as tarmac?
While not exactly the same chemical composition as tarmac, asphalt can be used to surface the same areas that were once surfaced using tarmac. Like tarmac, asphalt is an aggregate of gravel, sand and a binding agent, for asphalt this is bitumen and in tarmac, tar was the biding agent.
