Andhra Pradesh Tests Danish Fibre Technology Against Potholes
Andhra Pradesh is testing a new way to make roads stronger.
The test is taking place on a road that carries many heavy trucks.
These trucks and the rainy season often cause cracks and potholes.
Tiny fibres from Denmark are mixed into the hot material used to build the road.
The fibres help spread force through the road instead of letting cracks start in one place.
The company says the method can reduce deep grooves and cracking.
Officials hope the road will last up to half as long again as a normal road.
They will watch it during the monsoon before deciding whether to use the technology elsewhere.
Andhra Pradesh launched a pilot road project using Danish Asphalt Reinforcing Fibre Technology on July 4, 2025.
The trial covers the Mudigedu–Sanjamala road in Nandyal district, which carries heavy cement and granite freight.
The fibres combine aramid and polyolefin and are mixed into hot bitumen at less than one kilogram per tonne.
Manufacturer-cited tests report more than 50% less rutting and resistance to cracking across a wide temperature range.
Officials say the road could last up to 50% longer, but monsoon performance will determine whether the technology is expanded statewide.
- Who
- Andhra Pradesh’s Roads and Buildings Department, with technology from Danish Fibres A/S, is conducting the trial.
- What
- A pilot project is testing Danish fibre reinforcement mixed into asphalt to reduce cracks, rutting and potholes.
- Where
- The trial is on the Mudigedu–Sanjamala road in Banaganapalle constituency, Nandyal district, Andhra Pradesh.
- When
- The project was inaugurated on July 4, 2025, with monsoon performance to be monitored afterward.
- Why
- The road carries heavy freight from cement plants and granite quarries and has repeatedly deteriorated during monsoons.
Case for Wider Use
Reasons for Caution
Durability and maintenance
Case for Wider Use
Officials and the manufacturer say the fibres can reduce rutting and cracking, extend road life by up to 50%, and lower repair needs.
Reasons for Caution
The technology is still being tested on one road, and its success in Andhra Pradesh has not yet been established through the coming monsoons.
Statewide expansion
Case for Wider Use
The Roads and Buildings Department says the method could be scaled across Andhra Pradesh if the trial performs well.
Reasons for Caution
Expansion is conditional on observed performance, so the state has not committed to a full rollout.
Key facts
- Technology
- Danish Asphalt Reinforcing Fibre Technology using aramid and polyolefin fibres.
- Trial location
- Mudigedu–Sanjamala road, Nandyal district, Andhra Pradesh.
- Launch date
- July 4, 2025.
- Fibre dosage
- Less than one kilogram of fibre per tonne of hot bitumen.
- Reported rut reduction
- More than 50%, according to manufacturer-cited independent tests.
- Expected road life
- Officials estimate up to 50% longer than a conventionally built road.
- Next decision
- The state will consider wider deployment if the stretch performs well through the monsoons.
