Drainage Coefficient for Base Course given Structural Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Drainage coefficient = Structural Number for Base Course/ (Layer Coefficient*Actual Thickness Base Course Payment)
M_n = SN₂/ (a_n*T_a)
This formula uses 4 Variables

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Structural Number for Base Course: 150.5 Millimeter --> 150.5 Millimeter No Conversion Required
Layer Coefficient: 0.5 --> No Conversion Required
Actual Thickness Base Course Payment: 1200 Millimeter --> 1200 Millimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_n = SN₂/ (a_n*T_a) --> 150.5/ (0.5*1200)

Evaluating ... ...

M_n = 0.250833333333333

STEP 3: Convert Result to Output's Unit

0.250833333333333 --> No Conversion Required

FINAL ANSWER

0.250833333333333 ≈ 0.250833 <-- Drainage coefficient
