Number of Passes given Compaction Production by Compaction Equipment Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Passes = (16*Width of Roller*Roller Speed*Efficiency Factor*Lift Thickness*Pay Ratio)/Production due to Compaction
P = (16*W*S*E*L*PR)/y
This formula uses 7 Variables

Variables Used

Number of Passes - Number of Passes is the number of times a compactor (such as a vibratory roller or a plate compactor) passes over a specific area of soil or aggregate during compaction.
Width of Roller - (Measured in Meter) - Width of Roller is the physical width of the roller used in compaction processes, such as those employed in soil and pavement construction.
Roller Speed - (Measured in Meter per Second) - Roller Speed is the velocity at which a compaction roller moves over soil or other materials during the compaction process.
Efficiency Factor - The Efficiency Factor is a dimensionless parameter used to relate the strength or stiffness of improved soil (after treatment) to its original, untreated state.
Lift Thickness - (Measured in Meter) - Lift Thickness is the depth of a compacted layer of fill material placed during construction. This term is important in the compaction process, where fill material is often placed in layers.
Pay Ratio - (Measured in Cubic Meter) - Pay Ratio is the ratio between the effective stress and the total stress in soil mechanics.
Production due to Compaction - (Measured in Cubic Meter per Second) - Production due to Compaction is the exertion of force on something so that it becomes denser.

STEP 1: Convert Input(s) to Base Unit

Width of Roller: 2.89 Meter --> 2.89 Meter No Conversion Required
Roller Speed: 3 Kilometer per Hour --> 0.833333333333333 Meter per Second (Check conversion here)
Efficiency Factor: 0.5 --> No Conversion Required
Lift Thickness: 7.175 Millimeter --> 0.007175 Meter (Check conversion here)
Pay Ratio: 2.99 Cubic Meter --> 2.99 Cubic Meter No Conversion Required
Production due to Compaction: 297.59 Cubic Meter per Hour --> 0.0826638888888889 Cubic Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = (16*W*S*E*L*PR)/y --> (16*2.89*0.833333333333333*0.5*0.007175*2.99)/0.0826638888888889

Evaluating ... ...

P = 5.00015934675224

STEP 3: Convert Result to Output's Unit

5.00015934675224 --> No Conversion Required

FINAL ANSWER

5.00015934675224 ≈ 5.000159 <-- Number of Passes

What is Compaction?

In geotechnical engineering, soil compaction is the process in which stress is applied to a soil causes densification as air is displaced from the pores between the soil grains.

How to Calculate Number of Passes given Compaction Production by Compaction Equipment?

Number of Passes given Compaction Production by Compaction Equipment calculator uses Number of Passes = (16*Width of Roller*Roller Speed*Efficiency Factor*Lift Thickness*Pay Ratio)/Production due to Compaction to calculate the Number of Passes, The Number of Passes given Compaction Production by Compaction Equipment formula is defined as the number of times a compaction machine, such as a roller, passes over a particular area of soil or aggregate. Each pass contributes to the densification of the material by applying mechanical force, reducing air voids, and increasing particle interlock. Number of Passes is denoted by P symbol.
