Overview

The performance requirements for HS2 embankments necessitate a stiff fill material with a minimum shear wave velocity of 160m/s durable to environmental conditions for a 120 year design life. However much of the natural ground along the HS2 route yields cohesive fills which soften on wetting and can’t meet this requirement.

As a sustainable alternative to importing over 10 million m3 of quarried granular fill for phase 1 of the project alone, lime stabilisation is being used to improve the site won material to the required stiffness. 

This talk showcases highlights from an innovative programme of HS2 funded research and development delivered with collaboration between industry and academia which justified a 40% reduction to lime dosage. The programme delivered increased understanding of sulphate swell risks and enabled cold weather working.
