Concrete Roads Programme — Lifecycle Extension Works Framework
A multi lot specialist supplier framework to deliver focussed renewals, to maximise the life of the existing concrete pavement.
Lot 1 — Joint Repairs
Scheduled joint repair works to concrete road surfaces.
The work includes:
— the replacement of old joint material between slabs with new jointing,
— it also covers small patches and thin bond repair to cover faults, such as small to medium punch outs, spalled edges, failed patches less than ½ a slab, linear inline repairs up to 600 mm wide, by 150 mm deep, repair/replacement of ironwork and surrounds, previously repaired stud holes, kerb edging,
— repairs will use both flexible and rigid repair materials. The aim with the rigid repairs will be to use concrete to concrete repairs where possible,
— high performance joints between different materials, such as transitions and bridge decks,
— re-installation of loops or magnetometers,
— introduction and/or widening of construction joints.
The Lifecycle Extension Works contractors will be expected to provide:
• construction of chosen intervention;
• principal contractor duties;
• traffic management;
• welfare facilities;
• early contractor involvement into design phase;
• small works for localised planned repair.
Provides contingency for other lots should the suppliers in those Lots be unable to deliver the works.
Lot 2 — Bay Replacement and Slab Levelling
Scheduled bay replacement and slab levelling works on concrete roads.
— full slab removal and replacement with early strength rapid set concrete materials,
— ½ bay or greater full depth replacement,
— this allows for pre-formed and precast slabs to be used for rapid repaid,
— replacement of dowels between joints,
— removal of depressions or heaves,
— removal of previous significant asphalt repairs for replacement of concrete slabs,
— repair to stabilise ground conditions found under the base,
— repairs to transitions (concrete),
— introduction of additional reinforcement beneath, in slab.
Slab levelling between joints use vacuum grouting, grout injection or resin injection.
— stabilisation of the slab to raise it to improve longitudinal ride profile,
— stabilise transitions between different materials,
— stabilisation of areas adjacent to the mainline, such as laybys, entry and exit slips, embankments associated with the edge of the road.
Lot 3 — Surface Treatments
Scheduled surface treatment works on concrete roads.
— white topping,
— thin surface course over asphalt,
— deeper overlays in asphalt above 50 mm to a depth of 250 mm,
— surface re-texturing,
— longitudinal grinding,
— surface milling,
— repairs to transitions (asphalt),
— repair to high friction systems.
