Gives guidance on the two-stage stabilisation of cohesive soils, such as clay, using lime followed by cement, pfa and/or ggbs to produce a strengthened sub-base or base. Covers specification, site investigation, mix design, construction and testing.

Describes the European standard BS EN 14227 issued in November 2004 that covers hydraulically bound mixtures for road and other pavements. Explains how the new mixtures compare with those specified for use before that date and gives guidance on their selection and specification.

Provides design and specification guidelines for clients, designers and contractors wishing to use hydraulically bound mixtures for heavy-duty paving in areas subject to wheel/axle loading in excess of that permitted on public roads. Also covers mixture design, construction and control testing and includes a useful glossary of terms.

Provides design and specification guidelines for clients, designers and contractors wishing to use hydraulically bound mixtures for residential and commercial road pavements. Also covers mixture design, construction and control testing and includes a useful glossary of terms.

Provides design and specification guidelines for clients, designers and contractors wishing to use hydraulically bound mixtures for parking areas and hardstandings. Also covers mixture design, construction and control testing and includes a useful glossary of terms.

These guidelines for the stabilisation of sulfate bearing clays are based on current knowledge and experience. They aim to explain the mechanisms that cause sulfate heave, recommend methods for sampling and testing for sulfates and sulphides and describe measures to minimise the risk of sulfate-related disruption. This publication is an update of the original version, which was published in 2005.

Cores were taken as part of a UK Highways Agency project that assessed the performance of treated soft rocks and cohesive soils for road pavement foundations. This paper compares the properties of these cores with the original & current specifications, and the construction results for the treated layers.

This report reviews the test methods used to assess the potential for treated/stabilised soils to swell or disintegrate because of the presence of sulfates or sulphides in the soil.

This document is an introductory and technical guide to mix-in-place soil improvement and stabilisation. It outlines industry best practice and provides technical information plus signposts to industry standards and further reading. Revised 2019.

A range of project, product and site cases studies proving that implementation of industry best practice will deliver the environmental and cost benefits of soil stabilisation.

Making the case for the use of soil stabilisation by highlighting the range of environmental and economic benefits.

This report explains the environmental benefits of using soil stabilisation. Not least of which is the rehabilitation of brownfield land to reduce the pressure to build on greenfield sites, reduced use of virgin aggregates, reduced landfill, reduced lorry traffic.

This case study examines the potential that soil stabilisation offers for residential developments on difficult sites. The Gifford Lea retirement village Tattenhall project is one of two firsts: the first documented use of lime to improve soils for a residential development and the first such project to receive a comprehensive industry warranty.

This publication is one of two parts. Firstly, it outlines the benefits of soil stabilisation. Secondly, it provides a number of technical case studies from the HS2 project that demonstrate the potential of soil stabilisation to produce high performance materials for civil engineering use.
