Asphalt Paver Speed and Production Rate
Tons per hour and lane-feet per hour a paver lays at a given screed width, depth, and forward speed.
Example
You enter
- Paver forward speed (ft/min) 20
- Mat / screed width (ft) 12
- Compacted mat thickness (in) 2
- Compacted HMA density (pcf) 145
- Working minutes per hour 50
- Productive hours per day 8
You get
- Production 145.0 tons/hr
- Lane feet per hour 1000 lane-ft/hr
- Daily tonnage 1160 tons/day
- Daily lane feet 8000 lane-ft/day
Details, formula, and sources
With the daily output - the production the asphalt-tonnage takeoff assumes and that sizes the plant delivery and truck rotation.
tons_per_hour = speed x working_min x width x (depth/12) x density / 2000; lane_ft_per_hour = speed x working_min; daily = hourly x hours.
Paving production identity by name (production = laydown area rate x compacted density); NAPA laydown-rate practice.
The paving production identity is published earthmoving / paving practice; NAPA guides free at asphaltpavement.org.
