- 444 - SECTION 612 -- SEALING JOINTS
612.01 Description
1.This work shall consist of the preparation and sealing of transverse and longitudinal joints and joints aro und existing concrete repairs in the concrete roadway.
612.02 Material Requirements
1.The joints shall be sealed with hot-poured type joint sealing filler which conforms to the requi rements of Section 1014.
612.03 Construction Methods
1.Preparation of Joints a. All joints shall be prepared by removing old joint sealing filler or other foreign material by diamond-blade sawing or other suitable method which will produce acceptable results. De tails of the joints are shown in the contract. If the method of removing the ol d joint sealing filler creates a slurry, the joint shall be flushed with water to remove the slurry.
b.Immediately prior to sealing, the joints shall be sandblasted to remove any loose joint sealing filler or other foreign material remaining in the joint or adhering to internal surfaces of the joint after the initial preparation. The joints shall be dry and clean at the time of sealing.
2.Sealing Joints a. The Contractor shall furnis h the Engineer, the manufacturer's recommendations for mixing, application and temperature restrictions 7 days prior to work beginning. These recommendations shall be strictly followed. For hot pour material, in no case shall the sealing filler temperature exceed the maximum recommended by the manufacturer.
b.The joints shall be filled full depth as shown in the contract to 1/4 inch to 5/8 inch (3mm to 6mm) below the pavement surface. When proper pouring consistency is attained, the joints shall be filled as shown in the contract through the us e of a pressure type applicator equipped with a nozzle which will fit into the joints.
c.Material spilled on surfaces of the pavement adjacent to the joint or overfilling the joint will be cleaned away by the Contractor at no additional cost to the Department.
d.Joints shall not be sealed until after any corrective work or Diamond Grinding and Texturing Concrete Pavement is completed. Formed joint wells that are destroyed shall be re-constructed, and joints of insufficient depth shall be deepened prior to sealing.
612.04 Method of Measurement
1.Sealing joints will be measured for payment by the linear foot (meter) of joints sealed, measured to the ne arest foot (meter) as sealed, complete, in place and accepted by the Engineer.
2.“Sealing Concrete Repair Joints” is for those existing repairs that do not abut transverse and longitudinal joints. The work “Sealing Concrete Repair Joints” that abut existing transve rse and longitudinal joints is included in the quantity of “Sealing Joints ”, as shown in the contract. Sealing Joints 612.05 - 445 - 612.05 -- Basis of Payment
1.Pay Item Pay Unit Sealing Joints Linear Foot (LF) [Meter (m)] Sealing Concrete Repair Joints Linear Foot (LF) [Meter (m)]
2.When sealant materials comply with the Specification requirement, joint sealing shall be paid for at the c ontract unit price per linear foot (meter).
a.When testing results of on-si te materials is outside of the specified property ranges, joint sealing sh all be paid for at the contract unit price multiplied by the Pay Factor table below.
b.If the material is found to be out of specificati on, the material shall be rejected if not already used.
c.If the pay factor is less t han 1.00 and the material has been incorporated in work which is allowed to remain in place, the pay factor for the material is determined by the Table 612.01. Table 612.01 Pay Factor* Specified Property 1.00 Deviation of up to (+/-) 5.0% 0.95 Deviation of (+/-) 5.1% to 10.0% 0.90 Deviation of (+/-) 10.1% to 15.0% 0.80 Deviation of (+/-) 15.1% to 20.0% 0.70 Deviation of (+/-) 20.1% to 25.0% 0.40 or Reject Deviation of 25.1% or greater * When the specification requirement is stated as a perc entage, the test result deviation from the specificati on will be divided by the specification value. The resulting deviation percentage is then applied according to Table 612.01. * When more than one specified property exceeds specification tolerances, the largest pay factor reduction will be applied. * Material not meeting a Pass/Fail requ irement falls under the Pay Factor of 0.40 or reject.
d.Material that exhibits unac ceptable field application will be rejected and removed from the Depa rtment’s Approved Products List. Material already used shall be removed and replaced at no cost to the Department.
3.When disputes arise in test resu lts, the Department will select an independent laboratory for referee test ing on the remainder of the sample. The identity of the independent labo ratory will not be revealed until the selected laboratory has completed the referee testing.
a.Only the Contractor can init iate dispute resolution, and request referee testing. The Contractor shall in itiate the dispute resolution in writing to the Engineer within 30 days of re ceiving the notificat ion of deficiency.
612.05 Sealing Joints
- 446 - b. If the independent lab’s tests indicate failing results and pay deductions equal to or greater than the Department’s, the Contractor will reimburse the Department for the cost of testing. If the independent lab’s tests indicate that the material meets s pecifications or is at a pay deduction less than the Department’s, the Department will assume the cost of testing. When the independent lab’s tests indica te a pay deduction, the lesser of the Department’s and the independent la b’s deductions will be applied.
4.Payment is full compensation for all work described in this Section. - 447 - DIVISION 700 -- BRIDGES, CULVERTS, AND RELATED CONSTRUCTION 701 -- GENERAL REQU IREMENTS ......................................................... 451
