Is milling a separate quantity?

Yes — SY of pavement milled by depth, priced separately from new asphalt.

Where do lift thicknesses come from?

The typical section or pavement design sheet — never assumed from the plan.

Asphalt Paving Takeoff Guide

Short answer

An asphalt takeoff measures paved area in square yards per lift — surface, binder, base — then converts to tons using each lift’s thickness and mix density; milling is measured separately in square yards of pavement removed.

Pavement is priced by the ton but drawn by the square yard and the inch — the conversion through thickness and density is where takeoff math lives. Each lift in the pavement section is its own quantity.

The typical section drives everything: lift thicknesses, widths, and the edges where pavement meets curb, shoulder, or existing road.

What to measure

Paved area per pavement section — new, widen, resurface separately.
Each lift separately — surface, binder, structural courses.
Milling area and depth on resurfacing work.
Turnouts, driveways, and side-street tie-ins.
Base and subgrade areas where the section calls for them.
Shoulder pavement at its own section.

Asphalt paving takeoff units

Item	Unit	How measured
Asphalt surface / binder course	SY, then TN	Area × thickness × mix density
Base course (limerock, crushed agg)	SY or CY	Plan area, or volume by thickness
Milling / resurfacing removal	SY	Area of pavement milled, by depth
Tack and prime coat	SY or GAL	Area covered
Curb, gutter, sidewalks	LF / SF	From the typical section per run
Striping and markers	LF / EA	Per signing and marking plans

SY to tons

The conversion is volume times density: square yards × inches ÷ 36 gives cubic yards; times mix unit weight gives tons. Use the density your mix supplier or the governing spec assumes — a wrong density assumption scales the entire material cost.

Multiple sections, multiple scales

A corridor takeoff spans plan sheets at one scale and typical sections at another, plus details at a third. Calibrate each sheet before measuring — the paving plan, the typicals, and the tie-in details each stand alone.
