3.0 CONSTRUCTION METHODS AND PROCEDURES

3.1 Methodology or General Approach

After the sub-grade has been placed and compacted to the required density,the areas which will support the paving machine and the grade on which the

pavement is to be constructed shall be trimmed to the proper elevation by means ofa proper designed machine extending the prepared work areas compacted at least

6cm beyond each edge of the proposed concrete pavement. If loss of density resultsfrom the trimming operations, it shall be restored by additional compaction before

concrete is placed. If any traffic is allowed to use the prepared sub-grade or base,

the surface shall be checked and corrected immediately ahead of the placingconcrete. The sub-grade or base shall be uniformly moist when the concrete is

placed.

The concrete shall be placed with an approved slip-form paver designed to

spread, consolidate, screed and float-finished and freshly placed concrete in onecomplete pass of the machine in such a manner that a minimum of hand finish will

be necessary to provide a dense and homogenous pavement in conformance with theplans and specifications. The machine shall vibrate the concrete for the full width

and depth of the strip of pavement being placed. The sliding forms shall be rigidly

held together laterally to prevent spreading of the forms. After the final finish, butbefore the concrete has taken its initial set, the edges of the pavement along eachside of each side of transverse expansion joints, formed joints, transverse expansion

joints and emergency construction joints, shall be worked with an approved tool and

rounded to the radius required by plans.

Immediately after the finishing operations have been completed and the

concrete has sufficiently set, the entire surface of the newly placed concrete hassufficiently set, the entire surface of the newly placed concrete shall be cured inaccordance with either one of the methods described herein. The concrete shall not

be left exposed for more than hour between stages of curing or during the curingperiod.
