Gritter lorries called in to tackle NI's melting roads
It is snow joke... the winter gritting lorries are getting a summer outing as soaring temperatures melt Northern Ireland's roads.
The bitumen in some roads is softening in the heat and causing the stone chippings to sink down.
The Roads Service is using winter gritting lorries to spread fine dust on the worst affected roads.
A spokesman from the Department for Regional Development said the dust should soak up excess bitumen.
"When the full extent of the problem becomes clear, specialist re-texturing machines may be brought in to get rid of the excess bitumen, but this can only be done when the road surface has cooled and hardened," he said.
"In Northern Ireland and the rest of the UK and Ireland a softer grade of bitumen is used than in continental Europe, because of our generally cooler and damper climate.
"So, on the exceptional occasions when we do get Mediterranean-style weather, this sort of problem does arise on some of our roads."
