How Many Tonnes in 70 Cubic Metres of Type 1 Aggregate?

Type 1 aggregate is a commonly used construction material, often referred to as MOT Type 1 or crushed stone. It is widely used for sub-base layers in roads, driveways, and foundations due to its excellent compaction properties. If you’re working on a project that requires 70 cubic metres of Type 1 aggregate, you’ll need to determine the weight in tonnes to ensure accurate ordering and transportation.

Understanding the Density of Type 1 Aggregate

The weight of Type 1 aggregate depends on its density, which typically ranges between 2.2 and 2.4 tonnes per cubic metre. This variation occurs because the material’s composition can differ slightly depending on the source quarry and particle size distribution. For calculation purposes, an average density of 2.3 tonnes per cubic metre is often used.

Calculating Tonnage for 70 Cubic Metres

Using the average density of 2.3 tonnes/m³, multiplying this by the volume (70 cubic metres) gives:
\[ \text{Weight} = \text{Volume} \times \text{Density} \]
\[ \text{Weight} = 70 \, \text{m³} \times 2.3 \, \text{tonnes/m³} = 161 \, \text{tonnes} \]

Therefore, 70 cubic metres of Type 1 aggregate weighs approximately 161 tonnes. However, it’s always advisable to confirm the exact density with your supplier, as slight variations can affect the total weight required for your project.

Factors Affecting Weight Calculation

– Moisture Content: Wet aggregate weighs more than dry material due to water absorption.
– Compaction: Compacted Type 1 may have a higher density than loose-fill material.
– Material Composition: Variations in stone size and grading can influence overall weight.

For precise measurements, consult your supplier or request a weighbridge ticket upon delivery to ensure accuracy in large-scale projects. Proper calculations help avoid over-ordering or shortages, saving time and costs during construction.
