Tons = Area × (Thickness ÷ 12) × 145 ÷ 2000 Step 1: Enter project dimensions in feet to calculate area.
Step 2: Enter pavement thickness in inches.
Step 3: Select NJDOT mix type (HMA 64-22 standard or HMA 76-22 for high-traffic/Turnpike).
Step 4: Volume × 145 lb/ft³ ÷ 2000 = tons needed for your NJ project.
Asphalt Calculator New Jersey FAQs
What NJDOT HMA mix types are used in New Jersey?
NJDOT specifies Hot Mix Asphalt (HMA) with PG 64-22 binder for standard use and PG 76-22 for high-traffic areas like the Garden State Parkway and NJ Turnpike. Mix types include 9.5M64 (surface), 12.5M64 (intermediate), and 19M64 (base) with Superpave gyratory design.
How thick should a New Jersey driveway be?
New Jersey driveways should have 2.5-3 inches of asphalt over 4-6 inches of compacted aggregate base (Dense-Graded Aggregate or DGA). For heavy vehicles or sloped driveways, increase to 3-4 inches. NJ's freeze-thaw cycles require proper base preparation to prevent cracking.
What is the asphalt cost in New Jersey?
As of 2024, asphalt in NJ costs $110-$140 per ton for material only. Complete driveway installation runs $3-$6 per square foot ($4-$7 in North Jersey near NYC). Prices are higher than national average due to labor costs and disposal regulations. Get multiple quotes from NJRPA-certified contractors.
When can you pave asphalt in New Jersey?
New Jersey's paving season runs from April to November when ground temperatures exceed 50°F. The busiest (and most competitive) period is May-June and September-October. NJDOT allows paving down to 40°F air temperature with warm-mix asphalt (WMA) technology for late-season projects.
