How do you calculate road base?
Manual Calculator
- Multiply the length of the area by the width of the area = Square Feet.
- Multiply Square Feet by the Depth* = Cubic Feet.
- Divide Cubic Feet by 27 = Cubic Yards.
- Multiply Cubic Yards by 1.5 = Tons Needed.
How do you calculate soil compaction factor?
3.7 Calculate percent relative compaction by dividing the dry density of the material from the test site by that material’s moisture density relation curve’s maximum dry density, and multiply by 100%.
How do you calculate compaction?
The percent compaction for the field density test is calculated by dividing the dry density of the soil by the maximum dry density from the proctor test.
How do you calculate compacted gravel?
Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. This will tell you how many cubic yards of crushed stone you need. When using this equation, make sure all of your measurements are in feet.
What is compacted road base?
What is Road Base? Base materials can be granite roadbase, crushed gravel or limestone, which are then compacted to form a hard surface. They are frequently used in the construction of roads, paving substrates, hard stands, parking areas, footpaths and driveways.
How do you calculate base material?
How to Find Cubic Yards of Base Material
- Measure the length and width of the patio in inches.
- Multiply the length and width to find the area in square inches.
- Multiply the area by the gravel depth in inches to find the volume in cubic inches.
- Divide gravel cubic inches by 46,656 to find the amount of gravel in cubic yards.
How much does road base compact down?
Generally, road base is layed to a total depth of 100 to 150mm (10-15cm) around the entire area. For driveways, compact for every 50mm (5cm) layer and for pathways compact for every 60mm (6cm) layer.
How is compaction factor calculated?
By dividing the value of partially compacted concrete by the value of fully compacted concrete, the compaction factor is calculated and to the nearest second decimal place, it shall normally be stated.
How do you calculate compaction ratio?
Divide the volume of the loose trash by the volume of the compacted trash to achieve the compaction ratio. As an example, 16 cubic feet of loose trash compacted into a 4 cubic feet volume would have a ratio of four, or four to one.
What is the compaction factor of a cubic yard?
From the first example, the compaction factor = 1.237 based on 15% swell and -7% shrink for this material. 7.4 cubic yards * 1.237 = 9.15 cubic yards.
How do you calculate the compaction factor of gravel?
For instance, you need to place a 6″ layer of gravel inside a foundation. Your calculation of the area for a 20′ x 20′ wide with a depth of 6″ would give you a volume needed of 20 * 20 * .5 = 200 cubic feet. From the first example, the compaction factor = 1.237 based on 15% swell and -7% shrink for this material.
What are the four types of compaction effort on soil?
There are four types of compaction effort on soil or asphalt: ■Vibration ■Impact ■Kneading ■Pressure Soil Compaction Soil compaction is defined as the method of mechanically increasing the density of soil. In construction, this is a significant part of the building process.
What is Spike’s compaction factor?
Spike’s Compaction Factor The swell and shrink factors are based on the material in its original state. If you combine the two factors you get a factor (Spike’s compaction factor) which will convert loose state volume to compacted volume of the material.
