Structural Number for Base Course Solution

STEP 0: Pre-Calculation Summary
Formula Used
Structural Number for Base Course = (Layer Coefficient*Actual Thickness Base Course Payment*Drainage coefficient)
SN2 = (an*Ta*Mn)
This formula uses 4 Variables
Variables Used
Structural Number for Base Course - (Measured in Millimeter) - Structural Number for Base Course can be described as the ability of the base course to withstand the axle loads.
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.
Actual Thickness Base Course Payment - (Measured in Millimeter) - 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
Layer Coefficient: 0.5 --> No Conversion Required
Actual Thickness Base Course Payment: 1200 Millimeter --> 1200 Millimeter No Conversion Required
Drainage coefficient: 0.25 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
SN2 = (an*Ta*Mn) --> (0.5*1200*0.25)
Evaluating ... ...
SN2 = 150
STEP 3: Convert Result to Output's Unit
0.15 Meter -->150 Millimeter (Check conversion ​here)
FINAL ANSWER
150 Millimeter <-- Structural Number for Base Course
(Calculation completed in 00.004 seconds)
