Before you use the result
You don't need an engineer to tell whether pavement is in its 'protect it,' 'act soon,' or 'plan to replace' phase — the visible signs are reliable. This tool turns five plain-English observations into a 0–100 condition score, loosely modeled on how a Pavement Condition Index weighs cracking, surface distress, drainage, and age.
Use it to decide what kind of quote to request, to prioritize between several properties, or to sanity-check a contractor's recommendation. It's a screen, not a survey — a formal PCI and core samples give the definitive rating and repair scope.

How this calculator works
Five weighted questions. Cracking, surface condition, drainage, age, and edge/joint condition each contribute points — cracking and surface carry the most weight because they signal how close the pavement is to structural failure.
A 0–100 score. Your answers roll up to a percentage that maps to a maintenance stage.
A stage, not just a number. Good (protect it), Fair (act soon), Poor (plan repair), and Failed (plan replacement) each come with the action that stage calls for.
Quick reference
What each condition stage means
Plain-English stages and the maintenance strategy each one calls for.
| Stage | What you'll see | Typical strategy |
|---|---|---|
| Good (80–100) | Sound, sealed, minor wear | Preventive: crack seal + sealcoat on cycle |
| Fair (55–79) | Cracks, fading, minor failures | Crack seal, patch, sealcoat now |
| Poor (30–54) | Advancing distress, some base issues | Assessment + overlay or major patching |
| Failed (<30) | Breakup, drainage failure | Remove and replace failed areas |
Frequently asked questions
What is a pavement condition rating?
It's a score that summarizes how much distress a pavement is showing and how close it is to failure. Formal versions, like the Pavement Condition Index (PCI), run 0–100 based on a detailed distress survey. This tool gives a quick, plain-English version from five visual observations.
What is a good PCI score?
On the 0–100 PCI scale, roughly 85 and above is considered good, the 70s are satisfactory, the 50s–60s are fair, and below about 40 is poor to failed. Higher scores mean cheaper, preventive maintenance; low scores mean rehabilitation or reconstruction.
Can I rate my own parking lot?
Yes, for planning. Walking the lot and honestly rating cracking, surface, drainage, age, and edges gives a useful screen of what stage you're in and what to budget. A formal survey by a qualified professional is still needed for a definitive rating and repair design.
Why does drainage affect the score so much?
Because water is the primary enemy of pavement. Standing water and poor drainage let moisture reach and weaken the base, which is where most serious failure begins. Good pavement over a saturated base won't stay good for long.
