O’Keefe have designed and developed a bespoke operation that recycles utility and construction waste into British Standard compliant products for use in highway reinstatement and pavement applications. The process involves segregation, screening, grading and manufacturing of industry standard and bespoke Hydraulically Bound Materials (HBMs).
SMARTR® is an acronym that aptly describes the production process for HBMs that are suitable for use as base and sub-base material in carriageways, footways, car parks, and other pavement applications. The SMARTR® products are known by the trade name PAVIMENTUM®, abbreviated to PV. The name originates from the material that was used by the Romans for the construction of their roads over 2,000 years ago.
Stabilising: is carried out by blending the soils with binders to produce an engineered candidate material.
Materials: are strictly managed throughout the process to ensure only inert soils are used in production.
Arisings: come from a variety of sources including trench excavations and construction projects.
Regrading: takes place after screening and this defines the product suitability from the grading envelope.
Treating: the stabilised materials with hydraulic binders to produce British Standard compliant HBMs.
Re-Use: of ‘waste’ material reduces the need for expensive disposal and imported virgin aggregates.
PVI™ is O’Keefe’s Cement Bound Granular Mixture (CBGM A) predominately used in utility term contracts as a replacement for Type 1 for trench reinstatement. PVI™ is produced to BS EN 14227-1, conforms to the WRAP Production Quality Protocol and adheres to the Specification for Highway Works 800 Series.
