PART 3 - EXECUTION

3.1 PREPARATION OF THE CRACKS

A. Immediately before the installation of the crack sealant, the crack shall be thoroughly cleaned to remove oxidized pavement, loose aggregate and foreign debris. The preparation shall be as follows: 1. Cracks:

a. Hairline Cracks: Cracks that are less than 6 mm (1/4 inch) wide do not need routing, clean with compressed air.

b. Small Cracks: Cracks that are 6 to 20 mm (1/4 to ¾ inch) wide shall be routed to a nominal width 3 mm (1/8 inch) greater than the existing nominal width and to a depth not less than 20 mm (3/4 inch), sandblasted, and cleaned using compressed air.

c. Medium Cracks: Cracks that are 20 to 50 mm (3/4 to 2 inches) wide shall be sandblasted and cleaned using compressed air.



d. Large Cracks: Cracks that are greater than 50 mm (2 inches) wide shall be repaired using pothole repair techniques instead of sealing.

2. Routing: Routing of the cracks shall be accomplished using a rotary router with a bit that is at least 3 mm (1/8 inch) wider than the nominal width of the crack to remove all residual old sealant (resealing), oxidized pavement and any loose aggregate in the crack wall.

3. Sawing: Sawing of the cracks shall be accomplished using a power-driving concrete saw as specified in paragraph EQUIPMENT. The blade shall be stiffened as necessary with suitable dummy (or used) blades and washers. Immediately following the sawing operation, the crack opening will be thoroughly cleaned using a water jet to remove all saw cuttings and debris.

4. Sandblasting: The crack faces and the pavement surfaces extending a minimum of 13 mm (1/2 inch) from the crack edges shall be sandblasted clean. A multiple-pass technique shall be used until the surfaces are free of dust, dirt, old sealant residue, or foreign debris that might prevent the sealant material from bonding to the asphalt pavement. After final cleaning and immediately prior to sealing, the cracks shall be blown out with compressed air and left completely free of debris and water. Care must be exercised when sandblasting to prevent damaging the pavement.

5. Backup Material: Backup material shall be used on all cracks that have a depth greater than 20 mm (3/4 inch). The backup material shall be inserted into the lower portion of the crack as shown on the drawings. Care must be taken to ensure that the backup material is placed at the specified depth and is not stretched or twisted during installation.

6. Rate of Progress of Crack Preparation: The stages of crack preparation which include routing, sandblasting of the crack faces, air pressure cleaning and placing of the backup material shall be limited to only that linear footage that can be sealed during the same day.

3.2 PREPARATION OF SEALANT

A. Hot-poured sealants shall not be heated in excess of the safe heating temperature recommended by the manufacturer as shown on the sealant containers. 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 shall be withdrawn and wasted.

3.3 INSTALLATION OF SEALANT

A. Time of Application: Cracks shall be sealed immediately following final cleaning of the crack walls and following the placement of the backup material. Cracks that cannot be



sealed under the conditions specified, or when rain interrupts sealing operations, shall be recleaned and allowed to dry prior to installing the sealant.

B. Sealing the Crack: Immediately preceding, but not more than 15 m (50 feet) ahead of the crack sealing operations, a final cleaning with compressed air shall be performed. The cracks shall be filled from the bottom up to 3 mm (1/8 inch) below the pavement surface. Excess or spilled sealant shall be removed from the pavement by approved methods and shall be discarded. The sealant shall be installed in such a manner as to prevent 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. In no case shall gravity methods or pouring pots be used to install the sealant material. Traffic shall not be permitted over newly sealed pavement until authorized by the Contracting Officer. Cracks shall be checked frequently to ensure that the newly installed sealant is cured to a tack-free condition within 3 hours.

3.4 CRACK SEALANT INSTALLATION TEST SECTION

A. Prior to the cleaning and sealing of the cracks for the entire project, a test section at least 60 m (200 feet) long shall be prepared 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, the test section shall be inspected to determine that the materials and installation meet the requirements specified. If materials or installation do not meet requirements, the materials shall be removed and the cracks recleaned and resealed at no cost to the Owner. When the test section meets the requirements, it may be incorporated into the permanent work and paid for at the contract unit price per linear foot for sealing items scheduled. All other cracks shall be sealed in the manner approved for sealing the test section.

3.5 CLEANUP

A. Upon completion of the project, all unused materials shall be removed from the site and the pavement shall be left in a clean condition.

3.6 QUALITY CONTROL PROVISIONS

A. Crack Cleaning: Quality control provisions shall be provided during the crack cleaning process to correct improper equipment and cleaning techniques that damage the bituminous pavement in any manner. Cleaned cracks shall be approved prior to installation of the crack sealant.



B. Crack Seal Application Equipment: The application equipment shall be inspected to ensure conformance to temperature requirements and proper installation. Evidences of bubbling, improper installing, and failing to cure or set shall be cause to suspend operations until causes of the deficiencies are determined and corrected.

C. Crack Sealant: The crack sealant shall be inspected for proper cure and set rating, bonding to the bituminous pavement, cohesive separation within the sealant, reversion to liquid, and entrapped air and voids. Sealants exhibiting any of these deficiencies at any time prior to the final acceptance of the project shall be removed from the crack, wasted, and replaced as specified herein at no additional cost to the Owner.

C. Spread planting soil mix to a depth of 4 inches (100 mm) but not less than required to meet finish grades after light rolling and natural settlement. Do not spread if planting soil or subgrade is frozen, muddy, or excessively wet.

D. Unchanged Subgrades: If lawns are to be planted in areas unaltered or undisturbed by

excavating, grading, or surface soil stripping operations, prepare surface soil as follows:

1. Remove existing grass, vegetation, and turf. Do not mix into surface soil. 2. Loosen surface soil to a depth of at least of 6 inches (150 mm). Apply soil amendments

and fertilizers according to planting soil mix proportions and mix thoroughly into top 4 inches (100 mm) of soil. Till soil to a homogeneous mixture of fine texture.

3. Remove stones larger than 1 inch (25 mm) in any dimension and sticks, roots, trash, and other extraneous matter. Legally dispose of waste material, including grass, vegetation, and turf, off Owner's property.



E. Finish Grading: Grade planting areas to a smooth, uniform surface plane with loose, uniformly

fine texture. Grade to within plus or minus 1/2 inch (13 mm) of finish elevation. Roll and rake, remove ridges, and fill depressions to meet finish grades. Limit fine grading to areas that can be planted in the immediate future.

F. Moisten prepared lawn areas before planting if soil is dry. Water thoroughly and allow surface

to dry before planting. Do not create muddy soil.

G. Restore areas if eroded or otherwise disturbed after finish grading and before planting.
