Pavement & Roadway Standards — Source Registry

Airwai, Inc. | Living index of authoritative documents underpinning the LAIRA compliance matrices. Maintained since: May 11, 2026

Purpose

A single, scrape-ready index of reputable government, standards-body, and DOT publications cited across LAIRA's airfield, roadway, and sidewalk compliance work. This file is designed to:

  1. Document provenance for every claim in the compliance matrices.
  2. Survive ASTM/FHWA URL changes by tracking both canonical issuer pages and known mirror locations.
  3. Seed automation. Each entry follows a consistent schema so a future scraper (cron job + signed PDF cache + integrity hash) can build an in-house archive without re-doing the discovery work.
  4. Feed docs.airwai.com. When we lift this into the public docs site, each standard becomes a citation page with the PDF embedded or linked.

Schema (one entry per standard)

id:                # short slug, used as cross-reference

doc_type:          # standard | regulation | manual | guidance | handbook | technical report
edition_or_date:   # e.g. "20" for ASTM D6433-20, or "Dec 2023"
jurisdiction:      # federal | DoD | state-DOT-<state> | international
surface:           # airfield | roadway | sidewalk | parking | shared
primary_url:       # issuer's canonical page (preferred citation)

Scrape Plan (future automation)

When we build the in-house archive, the plan is:

  1. Cron a scraper (weekly) that walks every pdf_url and fallback_urls entry.
  2. SHA-256 hash + content-length check on each download to detect upstream document changes.
  3. Cache locally under docs.airwai.com/standards/<id>/<edition>/<filename>.pdf with a checksum file.
  4. On change, file an issue in the docs.airwai.com repo so a human reviews the diff before re-citing.
  5. Bump last_verified automatically on success.
  6. For pay-walled standards (ASTM, AASHTO): only metadata + non-substantive excerpts cached; full copies remain license-bound.
  7. Build a citation API at docs.airwai.com/api/citations/<id> returning the structured entry as JSON for use by sales decks, customer responses, and the CIP-package agent.

This registry is the seed file. Once we have ~50 entries (airfield + roadway + DoD + sidewalks + state DOTs + ICAO/STANAG), we lift it into the docs.airwai.com git repo as standards.yaml (split by domain) and the markdown rendering becomes a generated page.
