6、ntConcrete Pavements3. General Requirements3.1 The hot-applied crack filler shall be a compound thatwill effectively fill cracks in both asphalt concrete and portlandcement concrete pavements. The crack filler shall resist soft-ening and pickup by vehicle tires at ambient summer tempera-tures when u
7、sed in an appropriate manner. The material shallbe capable of being heated to the specified safe heatingtemperature (see 4.1) in appropriate melting units, shall becapable of being effectively applied to pavement cracksthrough pressure fed melter-applicator equipment, and shall besuitable for fillin
8、g cracks that are a minimum of38 in. in width(see Appendix X1).4. Physical Requirements4.1 Safe Heating TemperatureThe safe heating tempera-ture is the highest temperature to which the crack filler can beheated and still conform to all requirements of this specifica-tion. The safe heating temperatur
9、e shall be a minimum of 20F(11C) higher than the manufacturers minimum recommendedapplication temperature. For testing purposes, the pouringtemperature for specimen preparation shall be the safe heatingtemperature recommended by the manufacturer. The safeheating temperature shall be shown on all con
10、tainers and shallbe provided to the testing agency before any laboratory testsare begun.4.2 Softening Point The softening point of the crack fillershall be a minimum of 150F (65.5C).4.3 Cone Penetration, Non-ImmersedAt 77 6 0.2F (256 0.1C), 150 g, for 5 s, shall not exceed 70 units.4.4 Cone Penetrat
11、ion at 39.2F (4C)At 39.2 6 0.2F (46 0.1C), 200 g, for 60 s, shall be a minimum of 15 units.4.5 ResilienceAt 77 6 0.2F (25 6 0.1C), shall be aminimum of 30 % recovery.4.6 Asphalt CompatibilityThere shall be no failure inadhesion, formation of an oily exudate at the interface betweenthe crack filler a
12、nd the asphalt concrete specimen, or softeningor other deleterious effects on the asphalt concrete or crackfiller when tested at 140F (60C) for 72 h.5. Sampling5.1 Samples may be taken at the plant or warehouse prior todelivery or at the time of delivery, at the option of thepurchaser. If sampling i
13、s done prior to shipment, the inspectorrepresenting the purchaser shall have free access to the materialto be sampled. The inspector shall be afforded all reasonablefacilities for inspection and sampling which shall be conductedso as not to interfere unnecessarily with the operation of theworks.1Thi
14、s specification is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.33 onFormed-In-Place Sealants for Joints and Cracks in Pavements.Current edition approved June 1, 2006.

A batch or lot shall be considered asall finish
17、ed material that was manufactured simultaneously orcontinuously as a unit between the time of compounding andthe time of packaging or placing in shipping containers.5.3 The crack filler portion for testing shall be obtainedfrom the selected manufacturers original container in accor-dance with Practi
18、ce D 5167. The sample portion for testingwhich is added to and heated in the melter shall weigh 800 650 g.6. Heating6.1 Heat the material in accordance with Practice D 5167.6.1.1 The oil bath in the melter shall be heated to atemperature between the sealant safe heating temperature and75F (41.7C) ab
19、ove the sealant safe heating temperature, andin no case shall be more than 550F (288C). Add the sealantsample to the melter according to instructions in PracticeD 5167. After the sample has been added to the melter, the oilbath temperature shall be regulated within the above listedtemperature limits
20、 to raise the sealant temperature to themanufacturers recommended safe heating temperature withinthe required 1 h time as stated in Practice D 5167. The sampleshall then be maintained at the safe heating temperature whilebeing continuously stirred until a total of 90 min from the timethe first segme
21、nt was added to the melter has elapsed. Speci-mens for physical testing are then poured from the heatedmaterial.6.1.2 Required specimens for cone penetration and resil-ience testing shall be poured into appropriate sample containersuntil slightly overfilled, and then immediately leveled to flushwith
22、 the top of the sample container using a straightedge. Threespecimens in 6-oz (177-mL) sample containers shall be poured.Two are for cone penetration testing and one for resiliencetesting.7.

28、LAND CEMENT CONCRETE PAVEMENTSX1.1 Some, if not all, of the known materials conforming tothis specification may be damaged by heating at too high atemperature, or by heating for too long a time. Care should beexercised to secure equipment for heating and application thatis suitable for the purpose.
29、The material should be heated in akettle or melter, constructed as a double boiler, with the spacebetween the inner and outer shells filled with oil or other heattransfer medium. Positive temperature control, mechanicalagitation, and recirculation pumps should be provided. Othermethods of indirect h
30、eating satisfactory to the engineer may beused. The crack filler should be heated to a temperature that isat least the manufacturers minimum recommended applicationtemperature. Temperature should not exceed the material safeheating temperature.X1.2 Pavement cracks to be filled with material covered
31、bythis specification should be dry and clean of all dirt, dust, orother contaminants so that adhesion to the crack surfaces isdeveloped. Cleaning methods used shall be as required forspecific job conditions. Methods commonly used includeD 5078 95 (2006)2blowing with compressed air, routing, or use o
32、f a wire brushtype cleaner.X1.3 Several different application geometries are com-monly used for filling cracks with crack filler for various fillingsituations. Application should be performed in a neat, work-manlike manner.ASTM International takes no position respecting the validity of any patent ri
33、ghts asserted in connection with any item mentionedin this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.This standard is subject to revision at an
