Pavement Rutting Model Calculator

Explicit independently established permanent layer strains integrated to rut depth, no repetitions/temperature rutting coefficients invented. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.

Description

Layer rutting can be modeled by multiplying thickness by permanent strain.

Layer rutting can be modeled by multiplying thickness by permanent strain.^[1]

The modeled sum depends on supplied layer strains rather than predicting them from traffic or material properties. Use this tool to calculate pavement Rutting Model from the supplied measurements and assumptions.

When to use Pavement Rutting Model Calculator

Use this tool to calculate pavement Rutting Model from the supplied measurements and assumptions. Establish the SI units or caller unit basis, load signs, measurement interval, model conditions and independently chosen coefficients or references.

How to use Pavement Rutting Model Calculator and understand its results

Establish the SI units or caller unit basis, load signs, measurement interval, model conditions and independently chosen coefficients or references.
Enter callerRuttingLayerThicknessM, callerMatchedPermanentLayerStrainFractions, using the field meanings and rules below, then run the tool.
Read layerPermanentRutDepthsM, totalPermanentRutDepthM. Interpret the fields using their units, signs and evidence conventions below.
If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.

Input field	Meaning	Value type	Requirement
callerRuttingLayerThicknessM	Caller rutting layer thickness m	list of number	Required
callerMatchedPermanentLayerStrainFractions	Caller matched permanent layer strain fractions	list of number	Required

Enter nonempty aligned positive layer thicknesses in m and nonnegative permanent strains. Return thickness×strain per layer and their sum in m. Strains are not bounded to one by this implementation; no material or traffic model derives them.

rutDepthM=ΣlayerThicknessM_i×permanentStrain_i

Use the exact units, boundary rules, ordering and missing-evidence conventions above.

Output field	Meaning	Value type
layerPermanentRutDepthsM	Layer Permanent Rut Depths M; follow the units, sign, ordering and evidence convention stated above	list of number
totalPermanentRutDepthM	Total Permanent Rut Depth M; follow the units, sign, ordering and evidence convention stated above	number

Limitations and assumptions

The modeled sum depends on supplied layer strains rather than predicting them from traffic or material properties. Interpretation depends on the units, sampling scope and exact model described above.

All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
