Area and continuity
Large uninterrupted paving runs can reduce the rate by £4–£8/m², while fragmented phases materially increase standing time and joints.
Asphalt specification
Changing from conventional AC10 to SMA typically adds £4–£8/m² through higher material cost and tighter production requirements.
Access restrictions
Limited wagon access, short working windows or remote discharge points can add 15–30% to the installed rate.
Minimum loads
Small orders and part-load charges can add £8–£20/m² where delivered tonnage falls below an economical batch.
Night working
Out-of-hours paving commonly adds 20–40% for labour premiums, lighting, supervision and reduced output.
Regional haulage
Distance from the coating plant can add £2–£7/m², particularly where wagon turnaround constrains the laying gang.
