Asphalt Calculator
Calculate asphalt volume and approximate tonnage from road length, width, compacted thickness and density. Use single-layer or multi-layer mode.
Paved area0,00 m²
Asphalt volume0,00 m³
Net asphalt quantity0,00 ton
Asphalt incl. allowance0,00 ton
Approx. asphalt per m²0,00 kg/m²
Area = L × W · Volume = Area × Thickness/100 · Tonnage = Volume × Density · With allowance = Tonnage × (1 + Allowance/100)
| Layer | Thickness (cm) | Density (t/m³) |
|---|---|---|
| Wearing course | ||
| Binder | ||
| Bituminous base |
Wearing course tabakası0,00 ton
Binder course0,00 ton
Bituminous base0,00 ton
Net total0,00 ton
Total incl. allowance0,00 ton
Density varies with mix type and compaction. The default 2.40 t/m³ is an approximate preliminary value; use the project or mix-design density for final quantities.
Side Slope Calculator
Calculate side-slope length, horizontal run, H:V ratio, percent grade and angle from slope ratio, dimensions or angle.
Horizontal run H0,00 m
Slope face length0,00 m
Slope angle0,00°
Percent grade%0,00
H = V × (H:V ratio) · L = √(H² + V²) · Angle = arctan(V/H)
H:V ratio1,50:1
Slope face length0,00 m
Slope angle0,00°
Percent grade%0,00
H:V = H / V : 1 · L = √(H² + V²) · Grade (%) = 100 × V/H
Horizontal run H0,00 m
H:V ratio1,50:1
Slope face length0,00 m
Percent grade%0,00
H = V / tan(α) · L = V / sin(α) · H:V = H/V : 1
This tool performs geometric slope calculations only. Whether a soil or rock slope is safe depends on material properties, groundwater, loads, stratification and a proper stability analysis.
Terrain Slope / Elevation Calculator
Calculate terrain slope between two elevations, find a target elevation from grade and distance, or calculate the horizontal distance required for a given elevation difference and grade.
Elevation difference (End − Start)0,000 m
Eğim%0,00
Slope angle0,00°
Grade ratio1:∞
Direction—
Grade (%) = 100 × (End elevation − Start elevation) / Horizontal distance · Angle = arctan(Δh / L)
Elevation change0,000 m
Target elevation0,000 m
Description—
Target elevation = Başlangıç kotu + Distance × Eğim / 100
Required horizontal distance0,00 m
Slope angle0,00°
Distance = |Kot farkı| × 100 / |Grade (%)|
Use horizontal distance rather than slope distance. Positive grade means rising terrain; negative grade means falling terrain.
Excavation Calculator
Calculate in-situ excavation volume, loose haul volume after swell, and required truck trips from excavation dimensions.
In-situ excavation volume0,00 m³
Loose haul volume0,00 m³
Volume increase0,00 m³
Required truck trips0 trips
V = Length × Width × Depth · Vloose = V × (1 + swell/100) · Trips = ⌈Vloose / truck capacity⌉
Swell values are preliminary defaults. Verify actual soil classification, loading conditions and truck limits for the project. Sloped excavations require the actual geometry.
Cut and Fill Calculator
Calculate cut, fill, net earthwork and approximate loose haul volume from existing ground and design elevations using the Average End Area method.
| Station (m) | Existing elev. | Design elev. | Formation width | Status |
|---|
Total cut0.00 m³
Total fill0.00 m³
Net volume (Cut − Fill)0.00 m³
Loose haul volume0.00 m³
Total alignment length0.00 m
A = b·h + m·h² · V = L·(A₁+A₂)/2. A zero-depth point is interpolated where the alignment changes between cut and fill.
For preliminary quantity checks. Final quantities should use actual cross-section geometry and project-specific geotechnical assumptions.
Stormwater Runoff Calculator
Calculates peak runoff using the Rational Method.
Sewer Sizing Calculator
Enter the design population directly or project it to a target year; then calculate wastewater flow and a preliminary sewer pipe diameter.
Default per-capita flow, peak factor, minimum diameter, depth ratio and velocity criteria can be changed by the user. Final design must follow the relevant authority requirements and project criteria.
Hydraulics
Uses Manning's equation to calculate full-flow capacity or actual partial-flow conditions for a given inflow.
Pipe Sizing
Selects the first suitable standard pipe diameter based on design flow, slope and pipe material.
Concrete Calculator
Calculates net concrete volume and order quantity including waste for foundations, slabs, columns, beams and walls.
Rebar Weight Calculator
Fill in the first rebar row; use Add Row to enter additional diameters or bar lengths.
Formwork Calculator
Calculates approximate formwork area for foundations, columns, beams, walls and slabs.
Masonry Calculator
Calculates masonry area, volume and approximate unit quantity.
Pipe Slope
Calculates pipe slope from upstream and downstream invert elevations.
