About this app

Streamline your road construction, civil engineering, and earthwork calculations directly on the job site with RoadBase Pro. Designed specifically for civil engineers, project managers, general contractors, site supervisors, and equipment operators, RoadBase Pro delivers fast, accurate, and offline-first estimating tools without complicated workflows.

Eliminate guesswork, avoid costly material overages, and optimize logistics with 5 essential field calculators in one intuitive app.

KEY CALCULATOR MODULES:

1. Asphalt Tonnage & Paving Calculator
• Accurately calculate hot mix asphalt (HMA) and surface course tonnage.
• Estimate total volume, surface area, and material requirements based on road length, width, and compacted thickness.
• Custom density settings (pcf or kg/m³) to match local asphalt plant mix designs.

2. Base Course & Aggregate Calculator
• Estimate aggregate base course (ABC), subbase, crushed stone, and gravel quantities.
• Account for compaction factors, loose vs. compacted volumes, and material spread rates.
• Calculate required tons and cubic yards/meters instantly.

3. Dump Truck & Fleet Logistics Estimator
• Balance excavation output with haul truck cycle times.
• Calculate round-trip haul times, cycle efficiency, and exact trucks needed per day.
• Prevent paver standby or excavator bottlenecks on critical cut-and-fill operations.

4. Trench Volume & Excavation Calculator
• Calculate bank cubic volume (BCY) and loose cubic volume (LCY) for pipe, utility, and drainage trenches.
• Built-in soil swell factor and trench wall slope / benching adjustments.
• Plan backfill, bedding material, and spoil removal volumes efficiently.

5. Grade, Slope & Elevation Calculator
• Quickly determine slope percentage, drop/rise elevation, ratio (e.g., 1:4), and run distances.
• Verify cross slopes, crown slopes, embankment batters, and ramp grades with ease.
