Sources & Methodology
This calculator uses industry-validated benchmarks from published engineering research, OEM specifications, and independently verified mine site case studies. All defaults are conservative — engineers are encouraged to replace them with site-specific data from CMMS/ERP systems.
Disclaimer: All cost benchmarks are industry averages. Local fuel prices, labor rates,
and maintenance contracts will differ significantly by region and operation.
Use site-specific data (CMMS/ERP actuals) for final capital investment decisions.
Rolling Resistance · Defaults
Tannant & Regensburg (2001)
Guidelines for Mine Haul Road Design. University of British Columbia.
Provides the foundational rolling resistance surface type table used as default RR values:
4–6% unpaved gravel, 2.7–3.5% with stabilization treatment.

Truck Specs · Fuel & Tire Rates
Caterpillar Performance Handbook, Ed. 52 (2022)
Industry-standard reference for haul truck specifications. Source of all TRUCK_SPECS defaults
(payload, fuel burn L/hr, tire cost/hr, machine rates). Per-class maintenance benchmarks
cross-referenced with MINING3 fleet surveys and Cummins service data.

Speed · Tire Life · Water Fleet
GRT (Global Road Technology) Haul Road Management (2024)
Comprehensive haul road management case study including iron ore ramp (Australia):
+10 km/h speed gain from road condition improvement, 52% tire life improvement on treated ramp,
51% water truck fleet reduction, full fleet ROI methodology. Conservative industry default for
tire life gain per RR point: 12%/pt (GRT upper bound: 52%/pt).

Grading Reduction · Water Reduction
Envirofluid 56 km Haul Road Case Study
Documented 56 km unsealed haul road treatment project. Outcomes: 87.5% reduction in grader hours,
51% reduction in water truck operations, 6% fuel improvement fleet-wide. Basis for the
85% grading reduction coefficient used in the municipal calculator.
Source for: grading savings formula (85% reduction default)
Fuel Savings · Grade-Adjusted
Cypher Environmental / Shenhua Coal Mine (2015)
Published case study: 17.4% fleet fuel reduction achieved on a 19.8 km haul road after dust
suppression and road stabilization treatment. Annual savings: $3.6M USD. Represents the upper
bound reference for fuel savings. Conservative default: 3%/pt RR reduction
(real-world range: 3–17.4% depending on grade and conditions).
Source for: fuel saving coefficient upper bound
Fuel Savings · Real-World Average
Dust-A-Side & Michelin Controlled Test
Dust-A-Side studies (Brazil and South Africa) document 3–5% average real-world fuel reduction
from haul road dust suppression. Michelin controlled test on paved vs. unpaved surface:
7.5% fuel reduction. Combined with Shenhua data, these establish the 3%/pt default
for the flat/unknown grade fuel saving coefficient.
Source for: fuel saving default (3%/pt RR for flat roads)
Filter Costs · Per-Class Scaling
Propulsa / Rio Tinto Saguenay (Case Study)
Documented filter and maintenance savings from dust suppression at a Rio Tinto operation.
Air filter savings: >$125,000/vehicle/year. Provides the empirical basis for per-class
engine air filter cost scaling in the Dust OpEx calculator. Filter costs scale approximately
with truck engine displacement and payload class.

Gravel Loss · Municipal Formula
Frontiers in Built Environment (2020)
"Wearing Course Aggregate Loss Models for Unsealed Roads in Australia."
Frontiers in Built Environment. Establishes traffic-dependent gravel loss rates:
approximately 25 t/km/year at ADT=100, scaling with traffic volume. Replaces the
former hardcoded 300 t/km/yr constant that did not account for traffic volume.
Source for: municipal gravel loss formula (25 t/km/yr × traffic factor)
Unsealed Roads · Best Practice
ARRB Unsealed Roads Best Practice Guide (Ed. 2)
Australian Road Research Board guide covering wearing course life, optimal grading frequency,
and condition-based maintenance triggers for unsealed roads. Referenced for municipal
default grading frequency and road maintenance cost benchmarks.

Speed Improvement · Production Data
MaxMine Fleet Analytics Case Study
MaxMine fleet analytics platform case study documenting +10 km/h average speed improvement
after haul road condition improvement at an Australian open-cut mine. Corroborates
the GRT speed improvement data and validates the 8% speed gain default.
Source for: speed improvement default (8% / +10 km/h case study)
Haul Road Physics · Fuel Model
SAE Paper 2015-01-0050
Technical paper establishing methodology for calculating haul road roughness effects
on vehicle fuel consumption. Validates the physics-based grade-adjusted fuel savings
coefficient used when haul grade > 0: approximately 65% of total fuel consumed
on the loaded uphill leg.
Source for: grade-adjusted fuel savings formula (65% loaded uphill)
Engine Filters · Dust Ingestion
Machinery Lubrication & One Eye Industries
Industry references documenting hydraulic filter bypass failures in dusty conditions
(Machinery Lubrication) and engine filter failure modes from dust ingestion leading to
accelerated engine wear (One Eye Industries). Support the maintenance reduction estimates
for dust OpEx calculations.

Methodology notes: The calculator uses conservative defaults throughout. Key corrections
applied in the current version: (1) fuel and tire savings now apply only to travel hours,
not loading/dumping time (travelFraction correction); (2) a grade-adjusted fuel savings
coefficient is used when haul grade > 0, based on the physics of loaded vs. empty truck power demand;
(3) strip ratio is correctly applied only to mixed ore/waste roads; (4) per-class maintenance and
filter cost defaults scale with truck payload class. All defaults can be overridden with site-specific data.
