Pavement Fatigue Crack Model Calculator
Pavement spectrum Miner damage with independently calibrated per-bin fatigue failure counts, no universal crack-percent mapping or service life prediction. 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
Miner-style damage accumulates cycle-count fractions relative to failure counts.
Miner-style damage accumulates cycle-count fractions relative to failure counts.1
The uncapped sum is a model indicator rather than a crack probability or a mechanistic crack-growth prediction. Use this tool to calculate pavement Fatigue Crack Model from the supplied measurements and assumptions.
When to use Pavement Fatigue Crack Model Calculator
Use this tool to calculate pavement Fatigue Crack 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 Fatigue Crack 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 callerFatigueDamageRepetitionCounts, callerMatchedFailureRepetitionCounts, using the field meanings and rules below, then run the tool.
- Read linearMinerFatigueDamage. 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 |
|---|---|---|---|
| callerFatigueDamageRepetitionCounts | Caller fatigue damage repetition counts | list of number | Required |
| callerMatchedFailureRepetitionCounts | Caller matched failure repetition counts | list of number | Required |
Enter nonempty aligned nonnegative observed cycle counts and positive independently established failure counts. Finite fractional counts are accepted. Return Σobserved/failure without clipping, probability mapping or predicting a crack extent.
MinerDamage=ΣobservedCycles_i/cyclesToFailure_i Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| linearMinerFatigueDamage | Linear Miner Fatigue Damage; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
The uncapped sum is a model indicator rather than a crack probability or a mechanistic crack-growth prediction. 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.
