Road Defect & Pothole Logger
GPS-pin potholes, cracking, rutting and edge breaks with severity ratings — an offline windshield-survey logger that exports CSV/GeoJSON.
New road defect inspection
Windshield surveys are typically run annually per network; arterials and bus routes deserve a semi-annual pass plus post-monsoon/freeze checks.
Field guide: Road Defect & Pothole Logger
Pavement maintenance is triage: a ₹500 crack seal today prevents the ₹50,000 base failure two monsoons from now. A consistent defect log is what turns 'that road feels rough' into a defensible patching program. This logger is built for windshield and walking surveys — pick the defect type, size and depth class, let the phone GPS pin it, and keep moving; each entry takes under fifteen seconds.
Severity classes follow the low/medium/high convention used by ASTM D6433 (PCI) and Wisconsin's PASER manual, so the export feeds straight into a pavement-condition workflow. The 'Hazard — immediate' class separates same-day dispatch items (deep potholes in the wheel path, edge drops on narrow shoulders) from the programmable backlog.
Field tips
- Survey in the direction of traffic and log from the passenger seat — driver logs miss everything in the near wheel path.
- Depth matters more than area for dispatch: a 60 mm pothole the size of a dinner plate damages rims; a shallow 2 m² raveled patch can wait.
- Re-walk failed patches — a patch that failed within a year almost always signals a base or drainage problem, not a surface one.

Frequently asked questions
What's the difference between alligator cracking and longitudinal cracking?+
Alligator (fatigue) cracking forms an interconnected chicken-wire pattern in the wheel path and signals structural failure of the base — it needs patching or reconstruction. A single longitudinal crack often starts at a paving joint and can be crack-sealed cheaply if caught early.
When is a pothole an immediate hazard?+
Most agencies treat anything deeper than about 50 mm (2 in) in a travel lane, or any edge drop-off over 75 mm on a road without shoulders, as a same-day repair. Anything a motorcycle wheel can drop into deserves the 'Hazard' class regardless of area.
Can I use this for PCI or PASER scoring?+
This logger records defect type, severity and extent — the raw ingredients of both indexes. PCI (ASTM D6433) computes a 0–100 score from distress densities; PASER is a simpler 1–10 visual scale. Export the CSV and aggregate by segment to produce either rating.
How do I report locations without street addresses?+
Use the GPS button — coordinates are captured to six decimal places (about 10 cm of precision class). For linear referencing, put the route name and chainage (km+m) in the segment field; the export keeps both.
