| Title | Execution of special geotechnical works - Deep mixing |
| Work Item Number | 00288031 |
| Abstract/Scope | This document specifies general principles for the execution, supervision, inspection, testing and monitoring of in situ soil mixing works (Deep Mixing) carried out by two different methods: dry mixing and wet mixing. Soil mixing considered in this document is limited to methods which involve: ‒ mixing by rotating mechanical mixing tools, including jetting and/or compressed air assistance, where the lateral support provided by the surrounding ground is not removed; ‒ different shapes and configurations of soil mixing elements, either columns, panels, walls or any combination of more than one single element, with or without overlapping; ‒ treatment of soils and fills, including brownfields, sludges, etc., with possible limited penetration into the rock; ‒ mass mixing; ‒ environmental mixing, involving installation of containment and permeable reactive barriers and solidification/stabilization of contaminated soils and sludges. This standard does not apply to shallow soil stabilization, which consists of granulating the surface soil and mixing it with binder using soil stabilizing machines to improve soil performance as an alternative to soil replacement, typically in road works. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
In the case of undated standard, a link to the last dated version is provided.
In the case of series, a link to each standard identified in the series is provided.
We also invite you to check (via the website) whether corrigenda and/or amendments shall be read in conjunction with the main standard.
