Moresby Hall A595 Highway Improvement
Moresby Hall A595 Improvement Scheme
11,000m3 of Leca® LWA has been specified for the A595 Moresby Hall Improvement Scheme.
Two ship vessels were delivered into the Port of Workington - eliminating hundreds of road miles and significantly reducing co2 emissions.
Over several years the local authorities have been monitoring localised areas of movement within the embankment supporting the A595. A scheme was delivered by A.E. Yates Engineering to repair the embankment and improve drainage whilst maintaining the A595.
This included the specification of Leca® LWA.
Leca® LWA was used in conjunction with Geocells for the steep embankment requirements.
Alternative solutions would have included the expense of a new bridge construction or piling which could have created excessive costs and potential delays.
Two site compounds were established, one alongside each embankment of the A595. Here micro-tunnelling techniques were used to minimise disruption whilst establishing two bored tunnels under the embankment as part of the works to upgrade the drainage system along the A595
Furthermore, due to the steep embankment, large skips (holding 4-5m3 of material) and Small Skips (Holding 2m3 of material) were utilised to allow for the safe installation of Leca® LWA.
Using Leca® Lightweight Expanded Clay Aggregate on large scale cut and fill operations and construction on soft soils or bad ground can overcome stability problems, reducing the risk of landslide and deformation.
