The life expectancy of 36 roads in Central Beds has been extended by up to seven years thanks to a programme of micro-asphalting around the area.
The £400,000 project will improve Lowry Drive and Fensome Drive in Houghton Regis.
Cotswold Drive, Sandy Lane, Cheviot Close, Eriboll Close, Chiltern Gardens and Cleveland Drive in Leighton Buzzard will also be improved, as will Sheepcote Crescent in Heath and Reach.
Councillor Brian Spurr said: “By micro-asphalting we saved more than £1million in the short term without compromising on road quality.”
