Info

Paving and Surface Treatments • Hotmix asphalt paving is generally placed in layers or lifts (base, binder, and wearing course) • Thickness of lift is in proportion to the aggregate size • HMA is placed with temperatures ranging 250° - 330° F • HMA must be placed on a firm, stable, welldraining base
Hotmix Paving Placing HMA • Confirm that base (GABC, recycled crushed concrete, or gravel mix) has been compacted to required density and is stable • Existing surfaces must be swept clean • Tack coat applied to existing surfaces at the rate specified (DelDOT = CSS-1-h at 0.2 gal/SY) • Tack is also applied to curb, gutters, manhole frames and other surfaces where bonding is required
