Virginia Bitumen Calculator
Estimate tonnage, bitumen quantity, and cost for VDOT-standard mixes such as SM-9.5, IM-19.0 and BM-25.0.
Calculating Asphalt Tonnage for Virginia Paving Projects
VDOT district offices and the contractors who bid to them work off Superpave designations — SM-9.5A, SM-9.5D, SM-12.5A, BM-25.0 — and the mix you are allowed to use is fixed by traffic level and district, not by preference. That matters for estimating because binder content moves with the mix, and binder is the expensive part.
Set the mix, enter length, width and compacted lift thickness, and the tool returns tonnage split into binder and aggregate so you can price them separately. Imperial in, imperial out — feet, inches and short tons, the units VDOT bid documents actually use — or switch to metric and it converts internally. Default density is 145 lb/ft³ (≈ 2,320 kg/m³), which is where a dense-graded Virginia surface mix normally lands. Once your Job Mix Formula is approved, replace it with the measured value from the JMF and re-run the numbers.
Virginia Asphalt Tonnage Formula
VDOT projects typically work in imperial units (feet, inches, tons). This calculator handles both imperial and metric inputs, converting internally to produce accurate tonnage results.
Calculate Volume (ft³)
Convert thickness from inches to feet (÷ 12), then multiply all three dimensions. Example: A 300 ft Virginia secondary road, 24 ft wide, with 1.5-inch SM-9.5A surface course: 300 × 24 × (1.5 ÷ 12) = 900 ft³.
Convert Volume to Short Tons
Multiply volume by the compacted density and divide by 2,000. Using 145 lb/ft³ for a dense-graded surface mix: 900 × 145 ÷ 2,000 = 65.25 short tons of SM-9.5A. Add 5% waste = order about 69 tons.
Separate Bitumen & Aggregate
Apply the VDOT mix design binder content. At 5.7% binder: 65.25 × 0.057 = 3.7 tons bitumen and 65.25 × 0.943 = 61.5 tons aggregate. High-traffic SM-9.5D mixes use polymer-modified PG 70-22 binder at slightly higher cost.
Compacted SM-9.5A made with Virginia crushed limestone or diabase generally lands between 2,300 and 2,380 kg/m³ (144–149 lb/ft³). Northern Virginia projects on high-traffic routes typically require SM-9.5D (polymer-modified) with PG 70-22 binder. Always consult your VDOT-approved mix design JMF (Job Mix Formula) for final quantity calculations.

Where Virginia Asphalt Calculations Are Used
From I-95 corridor resurfacing to residential subdivision paving, Virginia contractors and engineers rely on VDOT-compliant tonnage estimates for accurate project budgeting and compliance.
VDOT Primary System Resurfacing
VDOT district engineers and their consultant teams calculate SM-9.5A or SM-12.5A tonnage for annual resurfacing programmes on primary routes and interstates. Quantity estimates feed into SYIP (Six-Year Improvement Program) budgets and IFB bid documents, with SM-9.5D and SMA-12.5 specified for high-stress interstate sections requiring rutting resistance.

Residential Driveways & HOA Roads
Virginia homeowners and HOA managers estimate asphalt tonnage for driveway installation and private road overlays. A typical 2-inch SM-9.5A surface over a 4-inch BM-25 base course requires separate calculations for each layer. Use the Cost Calculator with current Virginia supplier pricing ($90–$175/ton) to build accurate project budgets.

Northern Virginia Commercial & Parking Lots
Commercial developers and property managers in the NoVA/DC corridor use SM-12.5A calculations for parking lot construction and mill-and-fill projects. Heavy-use commercial sites often require a 3-inch surface course over 6-inch BM-25 base, with tack coat applied between layers. Estimate tack coat requirements separately using the Tack Coat Calculator.

How to Use This Calculator
Enter Project Dimensions
Input the length, width, and compacted thickness of your asphalt layer. VDOT SM-9.5A (surface mix) is typically placed at 1.5 inches; SM-12.5A at 2 inches. Residential driveways in Virginia commonly use a 2-inch surface over a 4-inch base course.
Select VDOT Mix Type
Choose the appropriate Virginia DOT Superpave mix — SM-9.5A or SM-12.5A for surface courses, IM-19.0A for intermediate, or BM-25.0A for base course. Virginia's humid subtropical climate requires PG 64-22 binder for most of the state, with PG 70-22 on high-traffic interstate corridors.

Four ways a Virginia take-off goes wrong
Each of these has a number attached. That is the point — a mistake you can price is a mistake you will remember.
| Mistake | What it does to the number | On a 65-tonne order |
|---|---|---|
| Using 110 as lb/ft³ | It is 110 lb per square yard per inch, not a density. Treating it as lb/ft³ scales everything by 110/145. | Short by ~16 t |
| Loose thickness instead of compacted | Asphalt loses roughly 20–25% of its loose depth under the roller. Estimating on loose depth over-orders. | Long by ~13 t |
| One density for a two-lift build | SM-9.5A surface and BM-25.0A base differ in both density and binder content. An averaged figure is wrong for both layers. | 2–4 t either way |
| No waste allowance | Truck bottoms, hand-work at gutter lines and the end of the mat all consume material that never gets paid for as area. | Short by 3–7 t |
This page carried exactly that error until July 2026. The worked example above read 49.5 short tons when it should have read 65.25. If you used this page before then, re-run your figure.
Frequently Asked Questions
Virginia DOT uses Superpave mix design under their Road and Bridge Specifications. Surface mixes include SM-9.5A, SM-9.5D (polymer-modified for high-traffic), SM-12.5A, and SMA-12.5 (stone matrix asphalt for interstates). Intermediate and base courses use IM-19.0A and BM-25.0A respectively. The "A" suffix indicates standard traffic levels; "D" denotes high-traffic polymer-modified mixes.
Virginia asphalt paving costs approximately $90–$175 per ton for materials. Installed cost for a residential driveway runs $3–$7 per square foot. Northern Virginia (NoVA) and the DC metro area carry higher labor costs than Southwest or Shenandoah Valley regions. Commercial projects and large parking lots typically get better rates due to volume.
About 2,320 kg/m³, or 145 lb/ft³, is a safe planning figure for VDOT Superpave surface mixes. The widely quoted “110” is not a density — it is 110 lb per square yard per inch of thickness, which works out at roughly 147 lb/ft³. Actual density depends on aggregate type and gradation — Virginia crushed limestone aggregates produce mixes around 2300–2380 kg/m³. Always use laboratory-verified values for final quantity estimates.
Both are VDOT Superpave surface mixes with a 9.5 mm nominal maximum aggregate size, but they differ in traffic level and binder specification. SM-9.5A uses a standard PG 64-22 binder and is designed for medium-traffic roads (≤ 10 million ESALs) — suitable for residential streets, secondary routes, and most collector roads. SM-9.5D uses a polymer-modified PG 70-22 binder for high-traffic roads (> 10 million ESALs), including primary routes, urban arterials, and interstate ramps. SM-9.5D provides significantly improved rutting resistance under heavy truck loads and is mandatory on Northern Virginia primary routes and I-95/I-81 corridors. The "D" mix carries a cost premium of approximately 15–25% over standard "A" mixes.
For a typical Virginia residential driveway (40 ft × 12 ft = 480 sq ft) with a 2-inch SM-9.5A surface course: 480 × (2/12) × 145 ÷ 2,000 = 5.8 short tons. With 5% waste, order about 6.1 tons. Adding a 4-inch BM-25 base course on the same driveway: 480 × (4/12) × 145 ÷ 2,000 = 11.6 tons. Total = roughly 17.4 tons combined. Use the Square Feet Calculator for quick area-based estimates.
A typical VDOT secondary road (State Secondary System, low-to-medium traffic) uses a flexible pavement structure consisting of: 1.5 inches SM-9.5A surface course + 2 inches IM-19.0A intermediate course + 4 inches BM-25.0A base course, over an aggregate base (21-A or 21-B stone) of 6–10 inches. Total asphalt thickness is typically 7.5 inches. Tack coat is applied between all asphalt layers at 0.05–0.10 gal/sq yd. Heavy-traffic primary routes may add a second intermediate layer. Always confirm with VDOT Pavement Design Guide for the specific traffic class and subgrade conditions.
Virginia's climate spans from the hot, humid Tidewater coast to the cold Appalachian mountain region, so binder grades vary by location. The most common grade is PG 64-22, covering most of central and northern Virginia for standard traffic. High-traffic primary routes require PG 70-22 (polymer-modified) for rutting resistance. Western mountain counties (Shenandoah Valley, Blue Ridge) may require PG 64-28 for improved cold-temperature flexibility. Coastal and Tidewater areas generally stay with PG 64-22. VDOT publishes a binder grade selection map in its Pavement Design Guide — always verify the applicable grade for your project location with your VDOT district materials office.
