THIS METHOD OF REMOVING DISTRESSED CONCRETE SHALL BE USED

IN CONJUNCTION WITH FULL DEPTH CAST-IN-PLACE REPAIRS LESS

THAN 50’-0" LONG AND IS OPTIONAL FOR REPAIRS OVER 50’-0"

IN LENGTH.

THIS FULL DEPTH SAW CUT IS MADE TO FACILITATE OPENING A

TRENCH ACROSS THE SLAB TO RELIEVE COMPRESSION IN THE

PAVEMENT PRIOR TO LIFTING OUT THE FAILED AREA. THIS SAW

CUT MAY BE OMITTED PROVIDED NO SPALLING OF THE REMAINING

CONCRETE OCCURS. IF SPALLING DOES OCCUR, THE CONTRACTOR

WILL BE REQUIRED TO MAKE THIS SAW CUT ON SUBSEQUENT

REPAIRS. WHEN THIS SAW CUT IS USED AND THE ADJACENT LANE

IS NOT REPAIRED, NO OVERCUTTING INTO THAT LANE SHALL BE

MADE.

IF REQUIRED, INTERMEDIATE SAW CUTS MAY BE MADE TO REMOVE

A SECTION OF PAVEMENT LANE WHICH IS OVER 6’-0" IN LENGTH,

TO PERMIT LOADING INTO THE HAULING UNITS.

ADDITIONAL SAW CUTS, AT CONTRACTOR’S EXPENSE, MAY BE MADE

INSIDE THE REPAIR LIMITS TO REDUCE 6’-0" BY 12’-0" OR

LESS SLABS INTO SMALLER PIECES TO FACILITATE REMOVAL.

THIS LONGITUDINAL FULL DEPTH SAW CUT IS MADE BETWEEN

LANES OR BETWEEN ANY COMBINATION OF THE FOLLOWING: LANE,

RAMP, CURB, CONCRETE SHOULDER, OR PARTIAL LANE WIDTH

REPAIR.

THE ADJACENT LANE. SHOULDER OVERCUTS WILL BE ALLOWED.

EXPANSION CAPS SHALL BE ACCORDING TO STANDARD PLAN R-40-SERIES.

THE SAME TYPE JOINT SHALL EXTEND ACROSS ADJACENT LANE REPAIRS.

WHEN Erg JOINTS ARE PLACED ADJACENT TO CONCRETE CURB AND GUTTER THAT

IS NOT REQUIRED TO BE REMOVED, AN Esc JOINT SHALL BE CONSTRUCTED IN

THE CURB AND GUTTER.

AFTER GROUTING IN-PLACE, RC-250 OR AN APPROVED BOND BREAKER SHALL BE

APPLIED TO THAT PORTION OF Crg AND Erg DOWEL BARS THAT EXTEND INTO

THE CAST CONCRETE.

DOWEL AND DEFORMED BARS USED IN Trg, Crg, AND Erg JOINTS SHALL BE

EPOXY COATED ACCORDING TO THE CURRENT STANDARD SPECIFICATIONS.

SAW OVERCUTS IN ADJACENT LANE, SHOULDER, RAMP, AND GUTTERS THAT WILL

REMAIN IN PLACE, SHALL BE CLEANED AND THEN SEALED WITH HOT-POURED

RUBBER-ASPHALT.

CONCRETE PAVEMENT REPAIRS (INCLUDING JOINT TYPES) OR PRESSURE RELIEF

DETAILS SHALL BE AS SPECIFIED ON THE PLANS OR IN THE LOG OF PROJECT.

JOINT RESERVOIRS FOR THE HOT-POURED RUBBER-ASPHALT SEALANT SHALL BE

ABRASIVE BLAST CLEANED, FOLLOWED BY A FINAL CLEANING OF OIL-FREE

COMPRESSED AIR PRIOR TO SEALING.

THE MONTH AND YEAR OF CASTING AND STATION NUMBER (IF REMOVED) SHALL BE

STENCILED ON EACH CONCRETE REPAIR.

WHEN THE CONCRETE PAVEMENT REPAIR IS CONSTRUCTED IN PREPARATION FOR

AN OVERLAY, Crg JOINT RESERVOIRS AND SEALANTS SHALL BE OMITTED AND

EXPANSION JOINTS (Erg) SHALL HAVE THE FIBER JOINT FILLER KEPT FLUSH

TO THE PAVEMENT SURFACE.

Erg JOINTS SHALL BE CONSTRUCTED ONLY WHEN THEY EXTEND ACROSS ALL

LANES, RAMPS, OR SHOULDERS.

WHERE THERE ARE NO REPAIR LOCATIONS WITHIN A 1000’ LENGTH, NO

EXPANSION SPACE WILL BE PROVIDED.

EXPANSION JOINT FILLER SHALL EXTEND THE FULL DEPTH OF THE REPAIR AND

BE FLUSH WITH THE EXISTING PAVEMENT SURFACE. PRIOR TO SEALING, THE

JOINT FIBER FILLER AT THE PAVEMENT SURFACE SHALL BE REMOVED BY CUTTING

1" WIDE AND 1 1/2 " DEEP TO PERMIT THE PLACEMENT OF THE HOT-POURED RUBBER

ASPHALT SEALANT. HOLES IN EXPANSION JOINT FILLER SHALL BE 1 1/2 "

MAXIMUM DIAMETER AND SHALL BE ALIGNED TO FIT DRILLED HOLES IN CONCRETE.

IF THE EXISTING PAVEMENT HAS A HMA SURFACE, THE SAW CUTS SHALL EXTEND
