Why we publish these guides
The first page of Google for "asphalt cost" and "asphalt thickness" is dominated by contractor lead-gen sites that have a financial interest in inflating numbers. We publish these guides because:
- Every default value comes from NAPA, FHWA, AASHTO, or RSMeans ? never from cached web averages
- Every guide is reviewed by an outside paving engineer before publication
- Every pricing claim has either a 2026 contractor invoice or RSMeans citation
- We don't take referral fees from contractors, so our recommendations aren't tilted
