Structural Number for Surface Course Solution

STEP 0: Pre-Calculation Summary
Formula Used
Structural Number for Surface Course = (Layer Coefficient*Actual Thickness)
SN1 = (an*Dn)
This formula uses 3 Variables
Variables Used
Structural Number for Surface Course - (Measured in Millimeter) - Structural Number for Surface Course can be described as the ability of the surface course that can 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 - (Measured in Millimeter) - Actual Thickness can be described as the design thickness of various layers of the courses for the flexible payments.
STEP 1: Convert Input(s) to Base Unit
Layer Coefficient: 0.5 --> No Conversion Required
Actual Thickness: 300 Millimeter --> 300 Millimeter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
SN1 = (an*Dn) --> (0.5*300)
Evaluating ... ...
SN1 = 150
STEP 3: Convert Result to Output's Unit
0.15 Meter -->150 Millimeter (Check conversion here)
FINAL ANSWER
150 Millimeter <-- Structural Number for Surface Course
(Calculation completed in 00.020 seconds)
