Structural Number to Withstand Anticipated Axle Loads Solution

STEP 0: Pre-Calculation Summary

Formula Used

Structural Number = Structural Number for Surface Course+Structural Number for Base Course+Structural Number for Subbase Course
S_N = SN₁+SN₂+SN₃
This formula uses 4 Variables

Variables Used

Structural Number - (Measured in Millimeter) - Structural number (SN) that is used as a measure of the ability of the pavement to withstand anticipated axle loads.
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.
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.
Structural Number for Subbase Course - (Measured in Millimeter) - Structural Number for Subbase Course can be described as the ability of the subbase course to withstand the axle loads.

STEP 1: Convert Input(s) to Base Unit

Structural Number for Surface Course: 150 Millimeter --> 150 Millimeter No Conversion Required
Structural Number for Base Course: 150.5 Millimeter --> 150.5 Millimeter No Conversion Required
Structural Number for Subbase Course: 151 Millimeter --> 151 Millimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_N = SN₁+SN₂+SN₃ --> 150+150.5+151

Evaluating ... ...

S_N = 451.5

STEP 3: Convert Result to Output's Unit

0.4515 Meter -->451.5 Millimeter (Check conversion here)

FINAL ANSWER

451.5 Millimeter <-- Structural Number

(Calculation completed in 00.004 seconds)
