CONCRETE PAVEMENT NOTES
1.
CP1.
PROVIDE JOINTS AS DETAILED ON SHEET C11.01.
CP2.
JOINTS REQUIRE ON GOING MAINTENANCE TO ENSURE
LONG TERM PERFORMANCE OF THE SLAB.
JOINTS AND SEALANTS SHOULD BE INSPECTED AND
REPAIRED AS NECESSARY AS PART OF THE ONGOING
MAINTENANCE PROGRAM.
DOWELS ARE TO BE STRAIGHT, TO THE LENGTH
SPECIFIED AND FREE FROM MILL SCALE, RUST AND OIL
CP5.
ALL SAWCUT JOINTS ARE TO BE FORMED USING AN
EARLY-ENTRY SAWCUT SYSTEM SUCH AS 'SOFFCUT'.
SAWCUTS TO BE FORMED AS SOON AS THE CONCRETE
HAS HARDENED SUFFICIENTLY THAT IT WILL NOT BE
DAMAGED BY SAWING. THE REQUIRED TIMING OF THE
SAWCUT IS SUBJECT TO ON-SITE CONDITIONS AND AS
SUCH IS THE RESPONSIBILITY OF THE CONTRACTOR,
HOWEVER AS A GUIDE, EARLY-ENTRY SAWING CAN
USUALLY BE UNDERTAKEN UPON COMPLETION OF
POWER FLOATING.
CURING OF ALL CONCRETE IS TO BE ACHIEVED BY KEEPING
SERVICES CONTINUOUSLY WET FOR A PERIOD OF 3 DAYS,
AND PREVENTION OF LOSS OF MOISTURE FOR A TOTAL OF
7 DAYS FOLLOWED BY A GRADUAL DRYING OUT. APPROVED
SPRAYED ON CURING COMPOUNDS THAT COMPLY WITH
AS3799 MAY BE USED WHERE FINISHES WILL NOT BE
AFFECTED (REFER MANUFACTURER'S SPECIFICATION).
POLYTHENE SHEETING OR WET HESSIAN MAY BE USED TO
RETAIN CONCRETE MOISTURE WHERE NOT PROTECTED
CP6.
ANY DEFECTS IN THE CONCRETE PAVEMENT ARE TO BE
REFERRED TO THE SUPERINTENDENT FOR REVIEW.
CP7.
THE CONTRACTOR SHALL TAKE MEASURES TO PROTECT
THE CONCRETE PAVEMENT FROM CONSTRUCTION
TRAFFIC AND OTHER CONSTRUCTION LOADS.
CP8.
WHERE STEEL FIBRE REINFORCEMENT HAS BEEN
SPECIFIED IT IS TO BE OF THE SIZE, TYPE AND DOSAGE
RATE SPECIFIED. NO SUBSTITUTION IS TO BE MADE
WITHOUT APPROVAL OF THE ENGINEER.
