SPALDING WESTERN RELIEF ROAD

SPALDING WESTERN RELIEF ROAD

Work on the north section of the Spalding Western Relief Road started in January 2022. The Spalding Western Relief Road will provide a new route around the west side of the town - linking the A1175 and A16 to the south and east of Spalding, to the B1356 to the north, via the B1172 Spalding Common. The development of this relief road was planned to tackle heavy traffic into the region. reduce delays and improve journey times for road users; lessen the impact of increased freight passing through Spalding and reduce traffic congestion in Spalding town centre

Over 28,000m3 of Leca® 10-20mm Lightweight Aggregate (LWA) was delivered through Walking Floor for the development of an MSE Wall, which was used in conjunction with the Tensar Grid System. This was a key solution in an area of poor ground conditions due to the nearby water rivers – so a reinforced soil embankment was required by the designers requiring a proven light fill solution. The combination of Leca LWA with Tensar’s Grid System is a proven and robust combined solution which has been used previously on the FARRRS bridge project completed in 2017. 

FACTS


Amount of material: 28,000m3 of Leca® Lightweight Aggregate 10-20mm

Interesting Fact: The combination of Leca LWA with Tensar’s Grid System is a proven and robust combined solution 

Delivery Method: Walking Floor

Overview of Project

Direct shipment of the Leca LWA which was within 10 miles of the project – limiting the use of trucks required to deliver through walking floor – minimising road mileage.

Using Leca® LWA 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. Used in road embankments, Leca® LWA exerts much lower horizontal earth pressures compared with other backfill materials, helps improve stability and reduce the need for counterfill.
