16、quirements.6. Aggregate6.1 Cover Aggregate, shall conform to Specification D1139and Classification D448.6.2 SizeAggregate should be as close to one size as iseconomically practical, preferably in the range of12 to14 in.(13 to 6 mm) for single surface treatments. For multiple surfacetreatments, aggre

17、gate in the range of 1 to12 in. (25 to 13 mm)is used for the bottom layer with each successive layer usingaggregate approximately12 the size of the previous aggregatelayer. Larger sizes may be used in multiple treatments.NOTE 1Aggregates larger than12 in. (13 mm) can cause objection-able tire noise.

18、NOTE 2Aggregates finer than18 in. (3 mm) are difficult to spreadevenly. Also, the finer the aggregate, the smaller is the tolerable range forthe bituminous material application rate.6.3 ShapeThe ideal shape is cubical. Flat or elongatedparticles are undesirable. Flat particles tend to become aligned

19、on their flat sides and may be completely covered withbituminous material when enough is used to hold the cubicalparticles in place. Rounded particles tend to roll and have poorretention, and therefore, are undesirable.6.4 CleanlinessClean aggregate is extremely important. Ifthe coarse aggregate par

20、ticles are dusty or coated with finematerial, the bituminous material may not adhere to theaggregate, resulting in loss of cover aggregate and poorperformance. It is recommended that the fraction passing theNo. 200 mesh screen not exceed 1 % by weight.7. Bitumen7.1 When asphalt cement is used, it sh

21、all conform to one ofthe following specifications: D946, D3381, D6114, D6154,orD6373.NOTE 3The grade of asphalt cement to be used depends on climaticconditions and amount and type of traffic.7.2 When cutback asphalt is used, it shall conform to eitherSpecification D2027 or Specification D2028.NOTE 4

22、Selection of cutback type (rapid-cure or medium-cure) andgrade depends on the type of construction, climatic conditions, amountand nature of traffic, and cleanliness of aggregate. Refer to Practice D2399for selection guide.7.3 When emulsified asphalt is used, it shall conform toeither Specification

23、D977 or Specification D2397.NOTE 5The emulsified asphalt type and grade to be used depends onthe type of construction, climatic conditions, amount and nature of traffic,and cleanliness of aggregate. Use Practice D3628 for a selection guide.Other types of emulsified asphalt may be used if experience

24、has shownthat satisfactory performance will result.7.4 When road tar is used, it shall conform to SpecificationD490.8. Application Rates8.1 The bituminous material application rate shall be esti-mated by using Practice D1369 for guidance.8.2 The bituminous material shall be applied by a bitumi-nous

25、distributor that has been calibrated for transverse andlongitudinal application rate by Practice D2995.8.3 The aggregate application rate shall be estimated byusing Practice D1369 as a guide.8.4 The aggregate shall be applied by a self-propelledmechanical spreader or other aggregate spreading device

26、 that iscapable of uniformly spreading the aggregate at the desired rateand width. The spreader shall be calibrated to apply thequantity of cover aggregate indicated by the design require-ments for a given project. This calibration can be accomplishedwith several sheets of canvas, each being one squ

27、are yard(square metre), and a suitable scale. This is done in a mannersimilar to Test Method D5624 for bituminous distributors.9. Precautions9.1 Surface treatment operations should not be carried outduring periods of cold or wet weather, or both. The surfaceshall be clean and dry while performing th

28、e work.9.1.1 The air temperature should be at least 50F (10C) inthe shade and rising before starting the operation. The opera-tion should not be permitted when the temperature is 60F(15.6C) or less and falling.9.1.2 The operation should not be carried out in the rain, orwhen rain is threatening.10.

29、Method of Sampling and Testing10.1 Sample materials in accordance with Practice D140.10.2 Calibrate application equipment in accordance with thefollowing standards:10.2.1 Determining Application Rate of BituminousDistributorsPractice D2995.10.2.2 Determining the Transverse Aggregate Spread Ratefor S

30、urface Treatment ApplicationsTest Method D5624.11. Construction Procedure11.1 Patch potholes, fill cracks, and repair damaged areas inexisting pavement or consolidated base.11.2 The surface to be covered should be cleaned with arotary broom or other approved means.11.3 Spray bituminous material at t

31、he specified rate andproper temperature for type and grade of material. The recom-mended viscosity range for spraying is 20120 cSt, kinematic(approximately 1060 SFS). A guide to the range that encom-passes the correct spraying temperature for various types andgrades of material can be found in the a

32、ppropriate standard forthe material (that is, asphalt cement, cutback asphalt, emulsi-fied asphalt, road tar).NOTE 6The flash point of some grades of bituminous materials isbelow 250F (121C); therefore, caution must be used when applying heatto these materials.11.4 Spread cover aggregate at the spec

33、ified rate immedi-ately behind the bituminous material spray application toD5360 092achieve maximum possible chip wetting depth. This is essen-tial in the case of asphalt cement and road tar because of therapid increase in viscosity with cooling, and is greatly desirablein the case of asphalt emulsi

34、ons and cutback asphalts tomaximize the meniscus effect. The cover aggregate should beplaced on the bituminous material within 2 min of thebituminous application.11.5 Roll the surface immediately after application of thecover aggregate, preferably with a pneumatic-tired roller, toseat chips in the b

35、ituminous membrane. The speed of the rollershould not exceed 5 mph. Depending on environment condi-tions, type and amount of bituminous material, three (3) passesof a 12 to 15-ton pneumatic-tired roller are normally used.Initial rolling of the aggregate should occur within 5 min of theapplication of

36、 the bituminous material, and the final of thethree coverages should be completed within 30 min.11.6 Control traffic speed until bituminous material has set.It is recommended that traffic speed not exceed 20 mph for aperiod of 4 h after placement of the surface treatment.11.7 For multiple surface tr

37、eatments, repeat steps 11.3-11.6.Successive applications should be applied only after theprevious bituminous surface has set and cured, usually one day.Remove excess aggregate before applying the second or thirdlayer of surface treatment.12.
