- Why in news
- On 23 February 2026, MoRTH highlighted its pilot of Mobile Quality Control Vans (MQCV) for checking National Highway construction quality in four states. The next phase, across 11 more states, is expected to be commissioned by June 2026.
- What it is
- Mobile Quality Control Vans are on-the-move labs fitted with non-destructive testing instruments. They let officials check the quality of ongoing National Highway works on site without damaging the construction. They are meant to shift quality control from a reactive to a proactive process.
- Pilot states
- The pilot runs in Rajasthan, Gujarat, Karnataka and Odisha.
- Instruments in the van
- Vans carry ultrasonic pulse velocity meters, rebound hammers, asphalt density gauges and reflectometers, among others.
- Ultrasonic Pulse Velocity meter
- It sends sound waves through concrete to reveal hidden cracks, voids and inconsistencies.
- Reflectometer
- It checks the visibility of road signs and markings, day and night.
- Quality Monitoring Portal
- MoRTH is developing a National Highway Quality Monitoring Portal with online test reports and real-time GPS tracking of vans.
Don’t confuse with Rebound hammer vs UPV meter: Rebound hammer measures surface hardness to estimate concrete strength. UPV meter sends sound waves through concrete to find internal cracks and voids.
Don’t confuse with Reflectometer vs Light-Weight Deflectometer: Reflectometer checks visibility of signs and markings. Light-Weight Deflectometer estimates compaction of soil and sub-base.
Science and technology: 57 Prelims questions since 2013; most test the concept behind the news, not the news itself. In Mains, 12 news-triggered questions.
Why it matters
- On-site testing catches quality defects early, improving highway durability and safety.
- Online reports and GPS tracking bring transparency and accountability to construction.
Problems
- Action on deficiencies rests with field offices, so enforcement depends on follow-through.
- A few vans across states may cover only a small share of the large highway network.
Way forward
- Make test reports public on the portal and link them to contractor penalties.
- Scale up the number of vans and train staff in using the instruments.

UPSC’s own questions that come close to this issue, from our Prelims and Mains banks.
No practice question for this one; the card may still help an answer. Why: Pilot in four states with testing tools; useful for infrastructure notes but a minor pilot with little chance of a question.
Worth revising until Prelims 2027: most news questions come within two years of the event.
