Layer Coefficient of Base Course given Structural Number Solution

STEP 0: Pre-Calculation Summary
Formula Used
Layer Coefficient = Structural Number for Base Course/(Actual Thickness Base Course Payment*Drainage coefficient)
an = SN2/(Ta*Mn)
This formula uses 4 Variables
Variables Used
Layer Coefficient - Layer Coefficient can be represents the strength of the material, this is the primary variable that factors in the type of material you plan to use for each layer.
Structural Number for Base Course - (Measured in Meter) - Structural Number for Base Course can be described as the ability of the base course to withstand the axle loads.
Actual Thickness Base Course Payment - (Measured in Meter) - Actual Thickness Base Course Payment can be described as the design thickness of various layers of the courses for flexible payments.
Drainage coefficient - Drainage coefficient is a value assigned to a pavement layer that represents its relative loss of strength due to drainage characteristics and exposure to moisture saturation.
STEP 1: Convert Input(s) to Base Unit
Structural Number for Base Course: 150.5 Millimeter --> 0.1505 Meter (Check conversion here)
Actual Thickness Base Course Payment: 1200 Millimeter --> 1.2 Meter (Check conversion here)
Drainage coefficient: 0.25 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
an = SN2/(Ta*Mn) --> 0.1505/(1.2*0.25)
Evaluating ... ...
an = 0.501666666666667
STEP 3: Convert Result to Output's Unit
0.501666666666667 --> No Conversion Required
FINAL ANSWER
0.501666666666667 0.501667 <-- Layer Coefficient
