Structural Number for Surface Course Solution

STEP 0: Pre-Calculation Summary

Formula Used

Structural Number for Surface Course = (Layer Coefficient*Actual Thickness)
SN₁ = (a_n*D_n)
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 = (a_n*D_n) --> (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
