STAKE BASKET ASSEMBLY SUFFICIENT TO PROVIDE SUFFICIENT STABILITY DURING CONCRETE

PLACEMENT FROM POSSIBLE MOVEMENT.

2. DOWELS TO MEET THE REQUIREMENTS STATED WITHIN THE SPECIFICATION. ALL MATERIALS TO

BE PROVIDED SHALL BE SMELTED AND MANUFACTURED IN THE UNITED STATES.

NOTES FOR RESEALING JOINTS:

1. UNLESS OTHERWISE INDICATED ON THE PLANS, IT IS THE INTENTION OF THIS PROJECT TO

RESEAL ALL EXISTING PCC PAVEMENT JOINTS. THIS INCLUDES ALL LONGITUDINAL AND

TRANSVERSE JOINTS IN AREAS SHOWN.

2. ALL EXISTING PAVEMENT CRACKS REMAINING AFTER FULL DEPTH CONCRETE REPLACEMENT HAS BEEN COMPLETED ARE ALSO TO BE RESEALED BY ROUTING THE CRACK, CLEANING, AND SEALING

WITH SILICONE SEALANT.

3. PRIOR TO RESEALING THE EXISTING JOINTS, ALL JOINT SPALL REPAIRS AND FULL DEPTH

REPLACEMENTS SPECIFIED BY THE PLANS ARE TO BE SATISFACTORILY COMPLETED IN

ACCORDANCE WITH APPLICABLE PLAN DETAILS, AND APPLICABLE SPECIFICATIONS.

4. THE EXISTING DEPTH AND WIDTH OF THE JOINTS ARE VARIABLE AND IS FURTHER AFFECTED BY THE EXISTING WIDTH OF THE JOINT AS THE BACKER ROD IS TO BE OVERSIZED TO FIT INTO THE

EXISTING JOINT AND BE COMPRESSED ENOUGH TO RESIST MOVEMENT DURING THE SEALING

OPERATION. IF NECESSARY, THE CONTRACTOR WILL SAW THE JOINT DEEPER AND OR WIDER TO MAINTAIN THE SPECIFIED RECESS DEPTH AND RATIO OF SEALANT MATERIAL. SEE SECTION 32 01

19 FOR ADDITIONAL INFORMATION. CONTRACTOR SHALL INSPECT THE EXISTING CONCRETE

AREAS REQUIRING RE-SEALING AND REPAIRS PRIOR TO SUBMITTING BID. THIS VISIT WILL ONLY

BE PROVIDED AT THE PRE-BID MEETING.

THE DETAILS AND NOTES MENTIONED WITHIN.

2. REPAIR LIMITS SHOWN ARE INTENDED FOR REMOVAL AND REPLACEMENT OF ALL DETERIORATED CONCRETE

AND TO MAINTAIN THE SIZE OF THE SPALL REPAIR TO THE MINIMUM PRACTICAL TO ENSURE A LASTING REPAIR

WHILE AVOIDING UN-NECESSARY REMOVAL OF SOUND CONCRETE.

3. WHERE SPALL REPAIRS ARE REQUIRED ON EACH SIDE OF A JOINT OR CRACK, A NON FLEXIBLE TYPE FILLER OR

INSERT SHALL BE SECURED IN ALIGNMENT WITH THE JOINT AFTER BREAKING OUT THE SPALLED CONCRETE.

UNDER NO CIRCUMSTANCES SHOULD A REPAIR BRIDGE THE JOINT OR PARTIAL DEPTH MATERIAL REST UPON

DOWEL BARS OR REINFORCEMENT.

4. CORNER SPALLS SHALL BE RECTANGULAR SHAPED AND THE SAWCUT BOUNDARIES SHALL BE NO LESS THAN 6"

FROM THE JOINT CORNER.

5. MAKE VERTICAL SAWCUT MIN. 2" DEEP, 2" MIN. FROM EDGE OF DISTRESSED AREA.

6. REMOVE ALL CONCRETE AND PATCH MATERIAL WITHIN SAWED AREA 1/2" INTO SOUND CONCRETE OR 2" MIN.

OR CHAIN TO VERIFY ALL UNSOUND MATERIAL HAS BEEN REMOVED. SPALL AREA SHALL BE CLEANED BY

WATERBLASTING PRIOR TO BONDING AGENT PLACEMENT.

7. A GROOVE MAY BE SAWED AT EXISTING JOINT LINES TO A POINT 1/2" BELOW THE PREPARED CAVITY SURFACE

TO HOLD NEW BOND-BREAKING MEDIUM IN PLACE DURING CONCRETE PLACEMENT.

8. A BOND-BREAKING/SEPARATION MEDIUM IS REQUIRED TO MAINTAIN EXISTING JOINTS. WIDTH OF THE MEDIUM

SHALL BE EQUAL TO THE WIDTH OF THE EXISTING GAP, AND SHOULD EXTEND AT LEAST 2" ON EACH SIDE OF

THE PREPARED CAVITY. THE MEDIUM SHOULD BE NEATLY INSTALLED TO PREVENT NEW GROUT OR CONCRETE

FROM BY-PASSING THE MEDIUM AND ENTERING THE JOINT SPACE.

9. USE A BONDING AGENT TO ENSURE GOOD CONTACT BETWEEN EXISTING PAVEMENT & PATCH MATERIAL.

10. GROUT AND PATCH WITH APPROVED CONCRETE MATERIAL PER MANUFACTURE'S SPECIFICATIONS.

11. TO REDUCE/MINIMIZE SHRINKAGE CRACKS DEVELOPING, CURING OF PATCH SHALL CONFORM TO

MANUFACTURE'S SPECIFICATIONS AND/OR SECTION 32 01 29.

12. AFTER PATCH HAS CURED, WIDEN & CLEAN EXISTING JOINT AND APPLY JOINT SEALANT AT ALL EXISTING

JOINTS PER DETAILS SHOWN ON CP501 AND ACCORDING TO SECTION 32 01 19.

13. FILL ALL OVERCUTS WITH EPOXY GROUT (OVERCUT TO BE SANDBLASTED PRIOR TO GROUT PLACEMENT).

14. SEALING PATCH/SLAB INTERFACE SHALL BE COMPLETED WITH A ONE-TO-ONE CEMENT GROUT.
