Pavement that carries loaded trucks needs a different section from pavement that carries cars, and the failures show up fastest at the points where trucks concentrate load: dock approaches, gate entrances, turning radii, dumpster pads, and anywhere a trailer parks with its landing gear down.
Ask what asphalt thickness and base depth is proposed, whether it varies between parking bays and truck routes, and what those numbers are based on. Confirm any stated thickness is compacted thickness. Concrete is common at dumpster pads and dock aprons even in an otherwise asphalt lot, precisely because those are point-load areas, so a proposal that paves them in asphalt without comment is worth questioning.
For sites with gates, rail crossings, or continuous operations, the access plan matters as much as the pavement. Ask how truck traffic is routed while a section is closed, whether the work can be staged so the yard keeps running, and what the reopening times are for each area.
The asphalt thickness guide for parking lots explains how pavement sections relate to use, and the commercial asphalt paving guide covers what to expect on larger commercial scopes.
