Holes have appeared on a road in Maidstone which has melted in the heat.
Roads bosses confirmed an investigation is underway to find out why the new surface failed in this week's high temperatures.
Witnesses reported seeing the damage on the A20 Ashford Road, where other works are already being carried out.
Kent County Council carried out a project to improve the A20 through Harrietsham, which began in September and finished in March.
A new 30mph speed limit was introduced and a new pedestrian crossing was installed.
As part of this a new microasphalt surface was applied, but pictures today show it pockmarked with holes.
The same type of asphalt works has now been postponed in another part of Kent.
A KCC spokesman added: "We are investigating a failure of the recently applied microsurfacing to the centre of Harrietsham.
"The contractor has been informed and sweepers are to attend and remove any loose stone."
Temporary traffic lights are already in place on the road at the railway bridge until tomorrow to enable South East Water to repair a leaking fire hydrant.
Meanwhile tips have been issued on how to function during the heatwave
