CAQM Framework Urban Road Paving Greening Dust Control

Show this topic for:

Why in news

  • CSIR-CRRI initiated specialized implementation training for PWD engineers on CAQM road dust mitigation standards.

What is the CAQM Road Framework?

  • A statutory standard framework issued by the Commission for **Air Quality Management (CAQM)** to curb fugitive road dust.
  • Mandates scientific paving of unpaved road shoulders, end-to-end greening of non-traffic surfaces, and dust suppression designs across NCR.

Technical execution focus

  • Combines civil design standards set by CSIR-CRRI with botanical greening to stabilize roadside soil.
  • Eliminates unpaved gaps on urban arterial roads to prevent particulate matter generation caused by vehicular turbulence.

Why it matters

  • Road dust contributes significantly to ambient coarse particulate matter (PM10) loads in urban airsheds.
  • Translates statutory environmental directives into field-level civil engineering specifications.

Key terms

CAQM

Statutory body established under the CAQM in National Capital Region and Adjoining Areas Act, 2021.

CSIR-CRRI

Central Road Research Institute, a premier national laboratory under CSIR focused on highway and road engineering.

Prelims facts

  • CAQM directions supersede state government orders within the National Capital Region regarding air quality.
  • CSIR-CRRI provides engineering standards for road design, pavement maintenance, and transportation planning.

Mains discussion

  • Strategies for managing non-vehicular fugitive dust sources in urban atmospheric air pollution.
  • Institutional coordination challenges between statutory air quality bodies and state infrastructure execution agencies.
