Project Details

Description

BEAR Scotland has been commissioned by Transport Scotland to carry out resurfacing works on the M8 carriageway. The works will consist of carriageway resurfacing and reinstatement of road markings for a length of 1.2km (1.39ha) to a maximum depth of 355mm inlay. Due to the integrity of the hydraulic bound materials (HBM) and the sensitivity within this section of the M8 a stress absorbing membrane interlayer (SAMI) will be laid on the HBM layer where applicable in place of a crack and seat treatment.

Construction activities for the resurfacing procedure are as follows:

  • Set up traffic management (TM) and mark out site,
  • Milling of existing bituminous material by road planer,
  • Jackhammer and compressor for breaking up surfaces not accessible by planer (e.g., around gullies),
  • Loader/excavator used to collect and move excess material,
  • Sweeper to collect loose material and provide clean laying surface,
  • Milled out/excavated materials all taken off site,
  • Tack/bond coat laid,
  • Binder material laid and compressed by paver (where required),
  • Material compacted using a heavy roller,
  • New bituminous surface course material laid by paver,
  • Material compacted using a heavy roller,
  • Mechanical sweeper to collect loose material,
  • HGV for removal and replacement of material,
  • Road markings and studs applied where necessary,
  • Remove TM and open road.

The works are programmed to be completed over the 2024/2025 and 2025/2026 financial years with works expected to begin on 31st March 2025. Works are programmed to be completed over ten nights (20:30 – 06:00). Traffic Management (TM) is currently programmed to be in the form of a full night time road closure with a signed diversion. Traffic will be diverted via M8 Junction 3, A899, M805, M879 to M8 Junction 3A Westbound Onslip.

Location

The scheme lies on the M8 carriageway, south of Boghall, within the West Lothian Council boundary, and is surrounded predominantly by areas of agricultural land.
