Asphalt Paving Project Timeline Estimator

1. Enter total paving area
Use the net area included in the paving activity or phase you want to schedule.

2. Enter expected daily coverage
Use a sustained daily area rate that reflects the paving width, haul supply, rolling operation, and typical site constraints.

3. Add nonproduction days if needed
Enter setup, transition, or other simple day allowances separately from the production rate.

4. Set the paving workweek
Choose how many days per week paving is normally planned.

5. Review workdays and weeks
Use production days to see rate-driven duration and total workdays for the broader planning allowance.

Formula:

Production days = Total paving area ÷ Daily coverage
Total workdays = Production days + Additional workdays
Approximate workweeks = Total workdays ÷ Paving days per week

Area and daily coverage must use the same surface-area unit. Additional workdays are a direct user-entered allowance.

The formula assumes a uniform average production rate. Multi-lift work or phased traffic control may need separate calculations for each stage.

What the result means

The result estimates how many planned workdays the entered paving area will take at the selected daily coverage after the added day allowance.

Convert the workday estimate to actual dates in a project schedule that includes weather, plant, traffic, and predecessor constraints.

Given: A roadway phase includes 150,000 square feet, expected coverage is 30,000 square feet per day, one additional day is allowed, and paving is scheduled five days per week.

Calculation:
Production days = 150,000 ÷ 30,000 = 5 days
Total workdays = 5 + 1 = 6 days
Workweeks = 6 ÷ 5 = 1.2 weeks

Result: 6 workdays, or about 1.2 workweeks.

The one extra day is visible separately from the five days driven by paving production.
