Section 502. HMA Crack Treatment

502.01. Description

This work consists of treating cracks in HMA surfaces using both a saw or rout and seal process and an overband process.

A. Definitions

Primary Crack. Crack ⅛ inch to 1¼ inch wide with less than 25% of its length having secondary cracking.

Secondary Crack. Series of parallel cracks with no or few interconnecting cracks to the primary crack.

502.02. Materials

Provide a material listed in the Qualified Products List. Follow manufacturer’s recommendation for material installation. Legibly mark containers with a non-fading, weather resistant ink or paint. Include the manufacturers name or trade name, batch number, recommended pouring temperature, and the maximum safe heating temperature on the label.

502.03. Construction

A. Equipment. Provide equipment capable of meeting the requirements of this subsection.

1. Compressed Air System. Provide and use a compressed air system that produces a continuous, high-volume, high-pressure stream of clean, dry air to prepare cracks. Equip the air compressor with a moisture separator to remove oil and water from the air supply.

Provide a compressor capable of producing at least 100 psi at a continuous air flow of 150 cfm.

2. Melter Applicator. Provide a melter applicator consisting of a boiler kettle equipped with pressure pump, hose, and applicator wand. Equip the unit with the following:

a. Shutoff control on the applicator hose;

b. Mechanical agitator in the kettle to provide continuous blending;

c. Thermometers to monitor the material temperature and the heating oil temperature; and

d. Thermostatic controls that allow the operator to regulate material temperature up to

425°F.

3. Application Wand. Apply the material using either a wand followed by a V-shaped or U-shaped squeegee or a round application head with a concave underside.

B. Pre-Production Meeting. Before beginning work, conduct an on-site pre-production meeting with the Engineer to discuss the following:

1. Contractor’s detailed work schedule;

C. Crack Preparation. Clean and dry cracks using compressed air and other tools to remove loose dirt, vegetation, and deleterious material. Clean cracks no more than 10 minutes before filling. Any debris or vegetation removed from cracks in a curb and gutter section will be removed and disposed at no additional cost to the Department.

D. Crack Treatment Methods

1. Saw or Rout and Seal. Treat primary transverse cracks in the pavement surface using the saw or rout and seal process. Treat primary transverse cracks in the shoulders unless otherwise directed. Saw or rout, clean, and fill all primary transverse cracks. The

Department defines a transverse crack as a crack less than 10 degrees off of perpendicular to the centerline. The following cracks should not be sealed:

a. Secondary cracks;

b. Multiple nearby cracks that have raveled; and

c. Multiple cracks that include broken asphalt.

Saw or rout all primary transverse cracks as defined above by creating a reservoir along the crack. Create the reservoir to a volume of at least 7.5 cubic inches per foot of crack and with a 1:1 width-to-depth ratio. Ensure that the finished reservoir walls are vertical and the reservoir bottom is flat. Fill the reservoir such that the final level is flush with the pavement surface and spread uniformly over the entire length of the crack. The width of the overband, including the routed reservoir, must be no more than 2½ inches wide with a thickness of ⅛ inch.

2. Overband. The Contractor will treat all other primary and secondary cracks with material placed in an overband configuration. Apply overband material to clean, dry cracks. Apply overband 4 inches wide, ±½ inch and from ⅛ inch to 3/16 inch thick. The

Contractor may increase the maximum application width to 6 inches for coverage of multiple cracks, with Engineer approval. Place temporary pavement markings before opening the road to traffic if overband material obliterates existing pavement markings.

Apply overband as follows unless otherwise required:

a. Stand Alone Overband Crack Fill. If no other surface treatment is required on the pavement, fill visible cracks in the road less than 1¼ inch wide.

b. Micro-Surfacing Preparation. If preparing the pavement for a micro-surface overlay, fill visible cracks in the road less than 1¼ inch wide. Allow to cure for a minimum of 3 days prior to placement of micro-surface.

c. Chip Seal Preparation. If preparing the pavement surface for a single or double chip seal, fill cracks with widths from ¼ inch to 1¼ inch or 3 feet or longer. Allow to cure for a minimum of 7 days prior to placement of chip seal.

d. Paver-Placed Surface Seal (PPSS). If preparing the pavement for a paver-placed surface seal, fill cracks with widths from ¼ inch to 1¼ inch or 3 feet or longer. Allow to cure for a minimum of 14 days prior to placement of PPSS.

e. HMA Ultra-Thin Overlay. If preparing the pavement for an HMA ultra-thin overlay, fill visible cracks less than 1¼ inch wide. Allow to cure for a minimum of 14 days prior to placement of the HMA ultra-thin overlay. Do not seal the following cracks when preparing the pavement for micro-surfacing, chip seals, paver-placed surface seals, or HMA ultra-thin overlays: Multiple nearby cracks that have raveled; Multiple cracks that include broken asphalt; and Multiple longitudinal cracks in each wheel path.

E. Weather Limitations. Place material at air temperatures from 45°F to 85°F. Do not place material if moisture is present in the crack.

F. Cure Time and Repair. Allow the material to cool before opening the road to traffic.

Apply detackifying solution, if required, to protect the uncured crack treatment material from tracking. Do not use blotting materials, including sand, aggregate, sawdust, or paper.

Repair treated pavement areas, damaged by traffic at no additional cost to the

Department.

G. Quality Control. Provide and follow a QC plan for production and construction processes.

Ensure that the QC plan addresses the following:

1. A detailed description explaining how field crews will determine primary transverse and all other primary and secondary cracks. Separately detail projects with multiple pavement sections;

2. The sealant material and equipment used to heat, handle, and apply sealant material in accordance with the manufacturer’s specifications. Provide the material manufacturer’s specifications to the Engineer upon request;

3. Saw or rout and seal operation reservoir configuration;

4. Procedures for crack cleaning;

5. Replacement criteria for cutting tools;

6. Controls implemented to ensure that flying dust and debris are not directed toward adjacent traveled lanes, pedestrians, parked vehicles, or buildings;

7. An action plan for adjusting crack sealing operations to address actual environmental conditions if adverse environmental conditions occur; and

8. Proposed procedure for monitoring the work to ensure that acceptance requirements are met.

H. Acceptance. Upon completion of work, schedule an inspection with the Engineer. The

Engineer will note deficiencies, including areas exhibiting adhesion failure, cohesion failure, missed cracks, or other factors the Engineer determines unacceptable. Correct the unacceptable work. Notify the Engineer upon completion of corrective work.
