GENERAL SITE NOTES:

1. CONTRACTOR TO THROUGHLY DRY AND CLEAN THE CRACKS AND

ANY AREA TO BE PATCHED OR REPAIR, WITH COMPRESSED AIR

(100CFM OR GREATER) TO REMOVE OXIDEZED PAVEMENT, LOOSE

AGGREGATE AND FOREIGN DEBRIS.

2. ALL DEBRIS TO BE DISPOSED OFF BASE. WASTE TICKETS TO BE

SUBMITTED TO PANG ENVIRONMENTAL DEPARTMENT.

3. SEALANTS TO CONFORM WITH ASTMD6690, TYPE II OR ASTM D6690,

TYPE I. PREFERRED BRAND: COLJOINT 6690 TYPE I AND II OR

APPROVED EQUAL.

4. BACKER ROD MATERIAL- WHEN REQUIRED, USE BACKER ROD

MATERIAL IN ALL CRACKS THAT OTHERWISE WOULD REQUIRE

EXCESSIVE SEALANT. PLACE THE BACKER ROD SO THAT THE TOP

OF THE BACKER ROD IS AT LEAST 3/4 INCH BELOW THE TOP OF THE

PAVEMENT. ENSURE THAT THE BACKER ROD MATERIAL IS PLACED

AT THE SPECIFIED DEPTH AND IS NOT STRETCHED OR TWISTED

DURING INSTALLATION.

5. RATE OF PROGRESS OF CRACK PREPARATION - LIMIT THE STAGES

OF CRACK PREPARATION, WHICH INCLUDE AIR PRESSURE

CLEANING AND PLACING OF THE BACKER ROD MATERIAL, TO ONLY

THAT LINEAR FOOTAGE THAT CAN BE SEALED DURING THE SAME

DAY.

6. PREPARATION OF SEALANT- DO NOT HEAT HOT-POURED SEALANTS

IN EXCESS OF THE SAFE HEATING TEMPERATURE RECOMMENDED

BY THE MANUFACTURER, AS SHOWN ON THE SEALANT

CONTAINERS. WITHDRAW AND WASTE SEALANT THAT HAS BEEN

OVERHEATED OR SUBJECTED TO APPLICATION TEMPERATURES

FOR OVER 4 HOURS OR THAT HAS REMAINED IN THE APPLICATOR

AT THE END OF THE DAY'S OPERATION.

7. SUBMIT MANUFACTURER'S INSTRUCTIONS 3 DAYS PRIOR TO THE

USE OF THE MATERIAL ON THE PROJECT. INSTALLATION OF THE

MATERIAL WILL NOT BE ALLOWED UNTIL THE INSTRUCTIONS ARE

RECEIVED.

8. TIME OF APPLICATION - SEAL CRACKS IMMEDIATELY FOLLOWING

FINAL CLEANING AND DRYING OF THE CRACK WALLS AND

FOLLOWING THE PLACEMENT OF THE BACKER ROD MATERIAL

(WHEN REQUIRED). PLACE SEALANT ONLY WHEN CRACKS ARE DRY.

RECLEAN CRACKS THAT CANNOT BE SEALED UNDER THE

CONDITIONS SPECIFIED, OR WHEN RAIN INTERRUPTS SEALING

OPERATIONS, AND ALLOW TO DRY OR DRY BY MECHANICAL MEANS

PRIOR TO INSTALLING THE SEALANT

9. SEALING THE CRACK - IMMEDIATELY PRECEDING, BUT NOT

MORE THAN 50 FEET AHEAD OF THE CRACK SEALING

OPERATIONS, PERFORM A FINAL CLEANING AND DRYING WITH

COMPRESSED AIR. CRACKS SHOULD BE FILLED NO HIGHER

THAN 1/8 INCH ABOVE THE PAVEMENT. REMOVE EXCESS OR

SPILLED SEALANT FROM THE PAVEMENT BY APPROVED

METHODS AND DISCARD IT. INSTALL THE SEALANT IN A

MANNER WHICH PREVENTS THE FORMATION OF VOIDS AND

ENTRAPPED AIR. SEVERAL PASSES WITH THE APPLICATOR

WAND MAY BE NECESSARY TO OBTAIN THE SPECIFIED

SEALANT DEPTH FROM THE PAVEMENT SURFACE. DO NOT

USE GRAVITY METHODS OR POURING POTS TO INSTALL THE

SEALANT MATERIAL. DO NOT PERMIT TRAFFIC OVER NEWLY

SEALED PAVEMENT UNTIL THE SEALANT HAS CURED. CHECK

CRACKS FREQUENTLY TO ENSURE THAT THE NEWLY

INSTALLED SEALANT IS CURED TO A TACK-FREE CONDITION

WITHIN 3 HOURS.

10. CRACK SEALANT INSTALLATION - TEST SECTION PRIOR TO THE

CLEANING AND SEALING OF THE CRACKS FOR THE ENTIRE

PROJECT, CONSTRUCT A TEST SECTION AT LEAST 200 FEET

LONG USING THE SPECIFIED MATERIALS AND APPROVED

EQUIPMENT TO DEMONSTRATE THE PROPOSED SEALING OF

ALL CRACKS OF THE PROJECT. FOLLOWING THE COMPLETION

OF THE TEST SECTION AND BEFORE ANY OTHER CRACK IS

SEALED, INSPECT THE TEST SECTION TO DETERMINE THAT

THE MATERIALS AND INSTALLATION MEET THE

REQUIREMENTS SPECIFIED. IF MATERIALS OR INSTALLATION

DO NOT MEET REQUIREMENTS, REMOVE THE MATERIALS AND

RE-CLEAN AND RESEAL THE CRACKS AT NO COST TO THE
