How to Calculate Asphalt Tonnage
Use a tape measure to determine distances. Convert the length, width and height measurements to feet by dividing by 12, since each foot contains 12 inches. Multiply the length times the width times the depth to obtain the volume in cubic feet of the space to be paved.
How many tonnes are in a cubic Metre of tarmac?
The following density conversion factors for estimating the amount of material needed once compacted are: Granular A & B = 2.4 tonnes/m3. ¾” Clear Stone = 1.8 tonnes/m3. Asphalt – 2.5 tonnes/m3.
How do you work out m2 on a calculator?
In order to work out square meters, measure the length and width of an area you’re calculating using meters and centimeters. Next you need to multiply the length and width together to get the area in square meters: Width x Length: 9 x 10 = 90.
Is tarmac cheaper than block paving?
The materials for tarmac are often cheaper, and the labour costs will be lower because tarmac takes less time to lay. That said, block paving only costs 10% more on average.
How thick should tarmac be?
The wearing course should be at least 20-25mm thick when rolled, and should not deviate from the correct level by more than ± 6mm. There should be no roller marks in the finished surface. We recommend a minimum fall of 1:80 for tarmac areas, although a fall in the range 1:40-1:60 is preferred.

How thick should asphalt driveway be?
Driveways range from 25mm to 40mm (30mm is the most popular). Limestone base course restricts you to 35mm+ in thickness. Carparks depends on traffic, cars 25-40mm (30-35mm most popular), heavy loads and trucks etc generally 35-50mm (40mm is the most popular). Hardstands are 40-100mm depending on loading and budget.
What is the volume of a ton of asphalt?
