Hertfordshire County Council survey the condition of every public road in the county each year to determine the surfacing options needed? The results of the survey are considered as well as other factors including: current road conditions, likely future deterioration, road usage, traffic and location. The surfacing types used in Hertfordshire are: micro surfacing, surface dressing and resurfacing. To find out more about these works visit: www.hertfordshire.gov.uk/surfacing.
For micro surfacing as an example the site team uses cold materials, so this treatment has a lower environmental impact than some other options.
