NJDOT projects use imperial units. This calculator accepts both imperial and metric inputs and converts internally to produce accurate short-ton results aligned with NJDOT Section 401 quantity standards.
Convert thickness from inches to feet (÷ 12), then multiply all dimensions. Example: A 500 ft NJ arterial road section, 36 ft wide (three 12-ft lanes), with a 1.5-inch I-19 surface course: 500 × 36 × (1.5 ÷ 12) = 2,250 ft³.
Multiply volume by density (110 lb/ft³) and divide by 2,000. 2,250 × 110 ÷ 2,000 = 123.75 short tons. Add 5% waste = order approximately 130 tons. High-density urban New Jersey projects often specify actual lab density (2,290–2,370 kg/m³) rather than the 110 lb/ft³ default.
Apply the I-19 binder content from the NJDOT mix design. At 5.6%: 123.75 × 0.056 = 6.9 tons bitumen (PG 64-22 for most NJ roads, PG 70-22 on Turnpike and high-traffic routes) and 123.75 × 0.944 = 116.8 tons aggregate. SMA mixes use 6.0–7.5% binder at premium cost.
New Jersey has some of the highest vehicle miles traveled (VMT) per lane-mile in the US, particularly on the NJ Turnpike, Garden State Parkway, and I-78/I-80 corridors. NJDOT specifies polymer-modified mixes (I-19CM or SMA) with PG 70-22 binder on these high-stress routes to resist rutting under heavy truck loads. Always confirm mix type and binder grade with the NJDOT project special provisions — using a standard mix on a high-traffic route will result in premature rutting failure.
From NJ Turnpike resurfacing to dense suburban road networks and residential driveway paving, accurate NJDOT-compliant tonnage estimates drive project budgeting across the Garden State.
The New Jersey Turnpike Authority and South Jersey Transportation Authority use SMA and polymer-modified I-19CM calculations for major resurfacing contracts. These high-traffic, high-speed routes carry among the heaviest truck loads in the northeast, requiring premium mix designs with accurate tonnage estimates for procurement planning and contractor payment verification based on certified plant tickets.

New Jersey's 565 municipalities maintain dense road networks of local streets, collector roads, and county routes. DPW superintendents and municipal engineers estimate annual I-5 and I-19 tonnage for road resurfacing budgets, mill-and-fill programmes, and ADA ramp reconstruction. The state's Local Aid programme funds many of these projects, requiring quantity justification in NJDOT-compliant formats.

Homeowners and commercial property managers across New Jersey estimate I-19 or I-5 surface tonnage for driveways, HOA roads, and parking lots. North Jersey's higher labor costs push installed prices to $5–$9/sq ft. Tack coat between a new surface lift and an existing base is required — use the Tack Coat Calculator to estimate emulsion quantities for the bonding layer.

Input the length, width, and compacted asphalt thickness. NJDOT I-19 (9.5 mm surface) is typically placed at 1.5 inches; 12.5 mm intermediate at 2–3 inches. New Jersey's high-traffic density requires robust pavement sections — residential driveways typically use 2 inches of surface course over a 4-inch base.
Choose the appropriate New Jersey DOT mix — I-5 (fine surface), I-19 (surface), or 9.5 mm Superpave. New Jersey's humid continental climate and heavy truck traffic on interstates like the NJ Turnpike and Garden State Parkway require PG 64-22 binder with a high traffic level (4E10+) specification for most highway projects.

New Jersey DOT uses a mix designation system based on aggregate size: I-5 (fine graded surface mix), I-19 (9.5 mm surface), I-19CM (polymer-modified for high-traffic), and 9.5 mm or 12.5 mm Superpave for state highways. Stone Matrix Asphalt (SMA) is used on heavily trafficked interstates. NJDOT Standard Specifications cover all material and compaction requirements.
New Jersey asphalt prices range from $100–$190 per ton for standard mixes. Northern NJ and areas near New York City tend to be at the higher end due to labor and equipment costs. Residential driveway paving typically runs $4–$9 per square foot installed in New Jersey. The state's dense suburban development means short haul distances from asphalt plants, which helps keep material prices competitive.
Yes. NJDOT Standard Specifications allow and in some cases require Reclaimed Asphalt Pavement (RAP) content in new mix designs. RAP percentages of 15–30% are common in base and intermediate courses, reducing material costs and environmental impact. Surface courses may contain up to 15% RAP under standard specs, with higher percentages allowed with special approval and additional testing.
Both are dense-graded hot mix asphalt surface courses under NJDOT specifications, but they differ in aggregate gradation and texture. I-19 (also called 9.5 mm Superpave in newer NJDOT specs) has a 9.5 mm nominal maximum aggregate size — it produces a smoother, finer surface texture and is commonly used on local roads, residential streets, and driveways where a smooth ride and fine appearance are priorities. I-5 is a finer-graded surface mix with smaller aggregate, producing an even smoother finish, often used for top lifts on high-volume roads and parking lots where a tight surface texture is desired. I-2 (12.5 mm intermediate) and I-19 base course are used for lower pavement layers. For high-traffic state routes and the Turnpike, SMA-9.5 or I-19CM (polymer-modified) provides superior rutting resistance.
A typical New Jersey residential driveway (50 ft × 10 ft = 500 sq ft) with a 2-inch I-19 surface course: 500 × (2/12) × 110 ÷ 2,000 = 4.6 short tons. With 5% waste = order approximately 4.8 tons. Most NJ residential driveways also have an existing base — if you're doing a full replacement with a new 4-inch base, add another 9.2 tons for the base layer. For a wider driveway (12 ft × 60 ft at 2 inches) = approximately 6.6 tons surface course. The Square Feet Calculator is ideal for quick driveway estimates.
Stone Matrix Asphalt (SMA) is a gap-graded mix with a high coarse aggregate skeleton and a rich, fiber-stabilized bituminous mortar that fills the voids. It was developed in Germany and widely adopted in the US for high-traffic highways. SMA has superior rutting resistance (due to stone-on-stone contact), excellent durability, and good wet-weather skid resistance. NJDOT specifies SMA-9.5 and SMA-12.5 on heavily trafficked interstates, the NJ Turnpike, Garden State Parkway, and select primary routes where conventional dense-graded mixes cannot withstand the heavy truck loads without rutting. SMA uses 6.0–7.5% binder content (higher than standard mixes) and requires cellulose or mineral fiber to prevent binder drain-down. It typically costs 20–35% more than standard dense-graded surface mixes.
North New Jersey and the New York City metro corridor consistently have the highest asphalt installed costs in the country for several reasons: (1) Labor costs — union prevailing wages on public works projects in NJ are among the highest in the US; (2) Traffic management — dense urban road networks require extensive night paving, traffic control setups, and shorter working windows, increasing crew costs per ton placed; (3) Permitting and compliance — NJDEP, local municipal, and county approvals add project overhead; (4) Equipment mobilization — congested urban environments increase equipment time and haul costs; (5) Premium mix specifications — polymer-modified and SMA mixes required on major routes carry material cost premiums. Material-only prices are actually competitive due to proximity to major asphalt plants, but installed costs of $5–$9/sq ft for residential work reflect the full labor and overhead burden.
