7、3 73COMPRESSION JOINT SEALS FOR CONCRETE PAVEMENTS04/08*NOTE: This guide specification covers the requirements for polychloroprene compression seals used for sealing joints of rigid pavements for airfields, roads, streets, hardstands, and other areas.Edit this guide specification for project specifi
8、c requirements by adding, deleting, or revising text. For bracketed items, choose applicable items(s) or insert appropriate information.Remove information and requirements not required in respective project, whether or not brackets are present.Comments and suggestions on this guide specification are

10、OTE: For U.S. Air Force pavements, the engineer will specify the uncompressed width of the seals to be used, and the width of the saw cut reservoir including tolerances. The minimum sawed joint seal reservoir width will be 13 mm (1/2 inch). The specified uncompressed seal width will be twice the spe
11、cified nominal saw cut reservoir width, i.e., for a 13 mm (1/2 inch) wide joint seal reservoir saw cut, a 25 mm (1 inch) uncompressed width joint seal should be specified.Total joint opening and movement must be considered SECTION 32 13 73 Page 3Provided by IHSNot for ResaleNo reproduction or networ
12、king permitted without license from IHS-,-,-when specifying the size of the joint and seal. The engineer should carefully consider all factors affecting the proper sizing of the joint seal to assure the seal remains within the allowable compression range and that the working range of the proposed se
13、al is always greater than the total movement of the joints. The computational procedures in UFC 3-250-08FA Chapter 7, Appendix C, should be followed. Factors to be considered are saw cut reservoir width including tolerances, maximum pavement thermal expansion and contraction, pavement shrinkage duri
14、ng curing and pavement temperature limitations during joint seal reservoir sawing.Compression joint seal size, general shape and dimensional tolerances, especially uncompressed seal width, must be shown on the drawings or specified in this section. Manufacturers literature is helpful in determining
15、the seal size with the anticipated joint movement.*1.1 UNIT PRICES*NOTE: Paragraphs MEASUREMENT and PAYMENT will be deleted for lump sum bidding.*1.1.1 MeasurementThe quantity of each sealing item to be paid for will be determined by measuring the length of in-place material that has been approved.1

Include in the unit bid prices the cost of all labor, materials, the use of all equipment, and tools required to complete the work.1.2 REFERE

22、f the work required by this section, approved before the work is started and maintained in satisfactory condition at all times.1.3.1 Joint Cleaning Equipment1.3.1.1 Concrete SawProvide a self-propelled power saw with water-cooled diamond saw blades for cutting joints to the depths and widths specifi
23、ed and for removing filler, existing old joint seal, or other material embedded in the joints or adhered to the joint faces.1.3.1.2 Sandblasting Equipment*NOTE: Sandblasting equipment with a 6 mm (1/4 inch) nozzle requires at least 3880 liters (137 cubic feet) per minute of air to function efficient
24、ly. A larger nozzle would not serve any useful purpose in cleaning a joint.*Include with the sandblasting equipment an air compressor, hose, and a long-wearing venturi-type nozzle of proper size, shape, and opening. The maximum nozzle opening should not exceed 6 mm 1/4 inch. Provide a portable air c
25、ompressor capable of furnishing not less than 4200 liters 150 cubic feet per minute and maintaining a line pressure of not less than 620 kPa 90 psi at the nozzle while in use. The compressor shall be equipped with traps that will maintain the compressed air free of oil and water. The SECTION 32 13 7
26、3 Page 5Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-nozzle shall have an adjustable guide that will hold the nozzle aligned with the joint about 25 mm 1 inch above the pavement surface and will direct the blast to clean the joint walls. Adjust th
27、e height, angle of inclination, and the size of the nozzle as necessary to ensure satisfactory results.1.3.1.3 Waterblasting EquipmentInclude with the waterblasting equipment a trailer-mounted water tank, pumps, high-pressure hose, a wand with safety release cutoff controls, nozzle, and auxiliary wa
28、ter resupply equipment. The water tank and auxiliary water resupply equipment shall be of sufficient capacity to permit continuous operations. The pumps, hoses, wand, and nozzle shall be of sufficient capacity to permit the cleaning of both walls of the joint and the pavement surface for a width of
29、at least 13 mm 1/2 inch on either side of the joint. A pressure gauge mounted at the pump shall show at all times the pressure in kPa psi at which the equipment is operating.1.3.2 Sealing Equipment*NOTE: Single-axle type seal application equipment should not be permitted; this tool tends to cause ex
30、cessive stretching and may cut or distort the seal. The following subparagraph may be added only for road, parking lot, and street pavements less than 1800 square meters (2,000 square yards), and for airfield and tracked pavements less than 450 square meters (500 square yards) in area:“The hand oper
31、ated joint seal application equipment shall be a two-axle, four-wheel machine that shall include means for compressing and inserting the compression seal into the joint and a reel capable of holding one full spool of compression seal. Provide auxiliary equipment to coat both sides of the joint or th
32、e seal with lubricant/ adhesive just prior to the installation of the compression seal.“*Equipment used to install the compression seal shall place the compression seal to the prescribed depths within the specified tolerances without cutting, nicking, twisting, or otherwise damaging the seal. The eq
33、uipment shall be capable of placing the seal with not more than two percent longitudinal stretch or compression of the seal during installation. The machine shall be an automatic self-propelled joint seal application equipment and engine powered. The machine shall include a reservoir for the lubrica
34、nt/adhesive, a device for conveying the lubricant/adhesive in the proper quantities to the sides of the compression seal or the sidewalls of the joints, a reel capable of holding one full spool of compression seal, and a power-driven apparatus for feeding the joint seal through a compression device
35、and inserting the seal into the joint. The equipment shall also include a guide to maintain the proper course along the joint being sealed. The machine shall at all times be operated by an experienced operator.1.3.3 Test RequirementsEach lot of compression joint seal and lubricant/adhesive shall be
36、sampled, SECTION 32 13 73 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-identified, and tested for conformance with the applicable material specification. A lot of compression seal shall consist of 1 days production or 6,000 meters 20,000 lin
37、ear feet for each cross section, whichever is less. A lot of lubricant/adhesive shall consist of 1 days production. Samples of the compression joint seal and lubricant/adhesive material shall be submitted and will be tested by the Government. No material shall be used at the project prior to receipt
38、 of written notice that the materials meet the laboratory requirements. The cost of testing the samples from each original lot supplied will be borne by the Government. If the samples fail to meet specification requirements, the materials represented by the sample shall be replaced and the new mater
39、ials tested. A cost of _ for Government testing of each lot of replacement material will be charged to the Contractor Testing of the compression joint seal and lubricant/adhesive material is the responsibility of the Contractor and shall be performed in an approved independent laboratory, and certif
40、ied copies of the test reports shall be submitted for approval _ days prior to the use of the materials at the jobsite. Samples of each lot of material shall also be submitted and will be retained by the Government for possible future testing should the materials appear defective during or after app
41、lication. Furnish additional samples of materials, in sufficient quantity to be tested, upon request. Final acceptance will be based on conformance to the specified test requirements and the performance of the in-place materials.1.4 SUBMITTALS*NOTE: Review submittal description (SD) definitions in S
