MCN is investigating stone chip road surfacing after receiving reports of crashes from readers.
According to the Road Surface Treatments Association there has been a "massive" increase in use of the stone chip by local authorities trying to cut costs. The technique, also called 'surface dressing' relies on passing traffic to embed stone chips onto bitumen.
