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.

SEALANTS IN EXCESS OF THE SAFE HEATING TEMPERATURE

RECOMMENDED BY THE MANUFACTURER, AS SHOWN ON THE

SEALANT CONTAINERS. WITHDRAW AND WASTE SEALANT

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

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
