Order size
Loads below efficient paving quantities can increase the rate by £8–£20/m² through minimum-load charges, mobilisation and reduced gang output.
Haul distance
Extended travel from the asphalt plant typically adds £2–£7/m² and increases the risk of rejected material arriving below laying temperature.
Access
Restricted delivery, short paving runs or repeated repositioning can add 15–35% to the standard rate.
Asphalt specification
Polymer-modified binders, enhanced stiffness or project-specific aggregate requirements can add £5–£14/m².
Programme constraints
Night shifts, weekend working or short possessions commonly increase the rate by 20–45% through premiums and lower productivity.
Substrate condition
Local regulating, cleaning and preparation beyond a paving-ready formation can add £3–£12/m² before substantive repairs are considered.
