Decision details
Highway Maintenance- Micro Asphalt Patching & Surfacing Programme 2020/21
Decision Maker: Assistant Director Highways and Capital Projects
Decision status: Recommendations Approved
Is Key decision?: No
Is subject to call in?: No
Purpose:
The condition the unclassified carriageway
road network was identified through our annual condition surveys as
requiring urgent attention. A business case was accepted into the
MTFP for £500k per year for three years to invest additional
funding to improve the condition and carry out preventative
treatments to halt or slow the decline.
The process involves repairs to deep failures followed by a
complete road surface covering stopping the ingress of water which
causes failures, therefore extending the life of the road by more
than ten years.
This micro asphalt treatment has been successful in stemming a
decline in condition data and delivering a 20% improvement in the
condition of the network. This year is the last year of the
additional funding and expect to see a further improvement.
When lockdown commenced a decision was taken by Cabinet to suspend
this year’s programme given the circumstances and guidance at
the time relating to Covid-19. Since then guidance has changed and
the contractor has been able to adapt to new working arrangements
and safely and successfully deliver this type of works in other
parts of the Country.
A review was undertaken of the DBC programme which is due
August/September and a proportion of the programme is now
considered deliverable subject to the new working arrangements. By
the time the programme commences there maybe further changes to
guidance which will able more of the programme to be delivered and
this will be kept under review. (see Appendix for revised
programme).
