Compaction commences after mixing. Typically stabilised materials are compacted to 95% standard, however higher compaction standards are achievable. Insitu mixing up to 400mm in a single layer requires compaction equipment large enough to achieve density throughout a layer this thick. Typically large self propelled vibratory padfoot rollers are used initially for deep compaction followed by a similar smooth drum to complete compaction of the full layer.   It is normal to commence trimming the pavement before the completion of the compaction operation, ensuring good bonding of any corrected shape before is finished. By seeking our advice early during the development stages of a project we can ensure savings are maximised by optimising the use of stabilisation in designs to reduce double handling and import and export of materials. We employ a number of qualified engineers and project managers offering sound advice based on years of experience. In order to assess a site accurately in terms of stabilisation, ideally the following information is considered: Geotechnical data including site conditions, material type and depth, sub-grade and existing pavement material. Construction conditions and loading. Geometric site layout proposed and existing. Proposed minimum area to be treated. Specification requirements typically in terms of density, CBR strength or binder content if provided. Proposed award and commencement dates.
