This work shall consist of routing and sealing transverse and longitudinal cracks in the asphalt concrete roadway surfaces indicated on the attached map with the specified sealant. MATERIAL: 1. The sealant material shall be low modulus, elastic type meeting the requirements of ASTM D6690 Type IV. 2. The material shall consist of asphalt and modifiers blended to produce a product with the following typical physical properties when tested after proper reaction of the material in a hot oil jacketed kettle for a minimum of 6 hours. Test Limits Cone Penetration at 77F 120-150 150 gr., 5 Seconds Flow, 140F 3.0 mm max. Cold Bond: -20F., 200% Extension 3 Pass Cycles Minimum Application Temperature 380 F Maximum Heating Temperature 400 F The Contractor shall submit a material specification sheet from the manufacturer showing test results for the above properties. The product name/number, name of the manufacturer, and the name of the supplier of the material shall also be provided. This information shall be included before any payment is made. 3. The material shall contain no water or volatile solvents and shall cure immediately upon cooling to sufficient viscosity to prevent tracking by traffic. CONSTRUCTION REQUIREMENTS: A. Routing 1. Routing equipment should be mechanical, power driven and capable of cutting a reservoir to the required dimensions. Equipment designed to plow the cracks to dimensions will not be permitted. Each side wall of the finished reservoir shall be vertical within a tolerance of 1/16 inch. 2. Cracks which are less than 3/4 inch in width or depth will require routing to a width and depth of 3/4 to 7/8 inch. 3. Cracks which are 3/4 inch or greater in width and depth will not require routing but shall be thoroughly cleaned of foreign material to a depth equal to the width of the crack. 4. The wall of the finished reservoir shall be vertical, and the reservoir bottom shall be flat. 5. Routing will not be allowed when the roadway is wet. B. Cleaning 1. Cleaning shall be accomplished with an air compressor producing a minimum of 125 CFM output and equipped with a maximum 3/4-inch nozzle. 2. Reservoirs and cracks shall be thoroughly cleaned of dust, dirt, and loose materials so that they are clean and dry at the time the blocking medium or sealant is applied. 3. If a routed reservoir or crack is left overnight, it shall be recleaned immediately before the blocking medium or sealant is applied. 4. As a second cleaning procedure, a heat lance will be used to clean out any remaining debris and/or moisture just prior to sealant placement. 5. All routed asphalt concrete and foreign material resulting from the reservoir preparation shall be removed from the roadway surface before any area is opened to traffic. C. Sealing 1. Cracks 3/8 inch or larger existing below the routed and cleaned reservoir shall be filled in two lifts, with the second lift installed once the first lift has had enough time to cure. All costs for installing two lifts in these locations shall be included in the contract unit price bid for "Crack Clean and Seal." 2. Sealant material shall be placed within 72 hours of routing. 3. There shall be no visible signs of moisture on the roadway surface or in the reservoir at the time the sealant is applied. 4. The sealant manufacturer's recommended handling, mixing and application temperature restrictions shall be strictly adhered to. 5. Sealant shall be applied with a pressure type applicator. 6. When applying the sealant, the reservoir shall be overfilled and squeegeed to provide a film of sealant on the roadway surface 1 to 3 inches on both sides of the reservoir. If, however, settlement occurs within the reservoir, a second application shall be done to fill all cracks to road level. 7. The squeegee shall be "U" shaped device, which will produce a full, uniform, and neat appearing reservoir and adjoining surface area. Other types of devices will require prior approval by the Engineer. 8. A blotting material such as toilet tissue or an all-natural, biodegradable, non-toxic liquid designed to prevent tracking and picking of freshly applied hot-melt crack and joint sealant such as Glenzoil 20 Plus or an approved equal product will be used. This product will allow shadow vehicles and traffic immediate access to the repaired pavement. 9. The Contractor shall repair or refill, at his own expense, any part of a sealed reservoir damaged by traffic. . Seasonal and Temperature Limitations 1. Routing and sealing of asphalt concrete surfaces shall be permitted only during daylight hours. See "COMPLETION DATE CONTRACT" below for completion dates. 2. Routing with a star bit type router will not be allowed when the air temperature is below 50 F. 3. Application of the sealant material will not be allowed when the air temperature is below 40 F. E. Traffic Control 1. Only one-half of the roadway shall be worked on at a time. 2. Routing and crack sealing shall be considered one work zone. A work zone shall not exceed two miles in length at any one time. 3. During weekends, nighttime and other non-working hours, all temporary traffic control devices, materials, and equipment shall be removed to a minimum distance of 30 feet from the driving lane. 4. Traffic shall be maintained on the driving lanes through the work area using flaggers at each end of the work zone, at all times. A pilot car will be required if traffic volumes and speeds through the work zone cannot be controlled using flaggers. Use of the shoulder as a driving lane shall not be permitted. The Contractor's traffic shall be in the same direction as public traffic. Routing and sealing of joints shall be considered a moving operation and shall be daylight operations. 5. Traffic approaching the project from intersecting roadways, streets, and approaches must be adequately accommodated. At major intersections or large commercial entrances, this may require additional signing, flaggers, and channelizing devices on a temporary basis until work activities pass these areas. 6. Traffic control shall comply with construction sign layout Type A on Standard Drawing D-704-15. Standard Drawings D-704-9, 10, 11, 11A, 12, 13, and 14 are also applicable. 7. Indiscriminate driving and parking of vehicles on the slopes and in the ditches will not be permitted. The Contractor at its expense shall restore damage as a result of such use. 8. All costs associated with traffic control shall be included in the unit price bid for "Crack Clean and Seal" and shall not be measured for separate payment Awarded GC: Northwest Asphalt & Maintenance $204,305.22 Plan to Award to Northwest Asphalt & Maintenance as they had the lowest bid amount.
