United States13.1.2 single surface treatmentthe bituminous surface produced by the application of bitumen to a prepared surface followedat once by an aggregate cover. The surface is immedi
15、ately rolled, preferably with a pneumatic-tired roller.3.1.3 surface treatmentan application of bituminous material followed by a layer of mineral aggregate. Multiple applicationsof bituminous material and mineral aggregate may be used.3.1.3.1 DiscussionThe terms “seal coat” and “chip seal” have bee
16、n used interchangeably with the term “surface treatment.”4. Significance and Use4.1 This practice is to be used as a guide and not a specification.5. Ordering Information5.1 Orders for seal coat and surface treatment materials under this guide shall include the following information:5.1.1 Type of bi
17、tumen (asphalt cement,binder, emulsified asphalt, cutback asphalt, road tar) specification designation,5.1.2 Grade of bitumen,5.1.3 Quantity of bitumen required,5.1.4 Type of aggregate (crushed stone, crushed gravel, crushed slag, gravel, slag) specification designation,5.1.5 Size or sizes of aggreg
18、ate to be furnished,5.1.6 Quantity of aggregate required, and5.1.7 Special requirements.6. Aggregate6.1 Cover Aggregate, shall conform to Specification D1139 and Classification D448.6.2 SizeAggregate should be as close to one size as is economically practical, preferably in the range of 12 to 14 in.
19、 (13 to6 mm) for single surface treatments. For multiple surface treatments, aggregate in the range of 1 to 12 in. (25 to 13 mm) is usedfor the bottom layer with each successive layer using aggregate approximately 12 the size of the previous aggregate layer. Largersizes may be used in multiple treat
20、ments.NOTE 1Aggregates larger than 12 in. (13 mm) can cause objectionable tire noise.NOTE 2Aggregates finer than 18 in. (3 mm) are difficult to spread evenly. Also, the finer the aggregate, the smaller is the tolerable range for thebituminous material application rate.6.3 ShapeThe ideal shape is cub
21、ical. Flat or elongated particles are undesirable. Flat particles tend to become aligned on theirflat sides and may be completely covered with bituminous material when enough is used to hold the cubical particles in place.Rounded particles tend to roll and have poor retention, and therefore, are und
22、esirable.6.4 CleanlinessClean aggregate is extremely important. If the coarse aggregate particles are dusty or coated with fine material,the bituminous material may not adhere to the aggregate, resulting in loss of cover aggregate and poor performance. It isrecommended that the fraction passing the
23、No. 200 mesh screen not exceed 1 % by weight.7. Bitumen7.1 When asphalt cementbinder is used, it shall conform to one of the following specifications: D946, D3381, D6114, D6154,or D6373.NOTE 3The grade of asphalt cementbinder to be used depends on climatic conditions and amount and type of traffic.7
24、.2 When cutback asphalt is used, it shall conform to either Specification D2027 or Specification D2028.NOTE 4Selection of cutback type (rapid-cure or medium-cure) and grade depends on the type of construction, climatic conditions, amount and natureof traffic, and cleanliness of aggregate. Refer to P
25、ractice D2399 for selection guide.7.3 When emulsified asphalt is used, it shall conform to either Specification D977 or Specification D2397.NOTE 5The emulsified asphalt type and grade to be used depends on the type of construction, climatic conditions, amount and nature of traffic, andcleanliness of
26、 aggregate. Use Practice D3628 for a selection guide. Other types of emulsified asphalt may be used if experience has shown that satisfactoryperformance will result.7.4 When road tar is used, it shall conform to Specification D490.8. Application Rates8.1 The bituminous material application rate shal
27、l be estimated by using Practice D1369 for guidance.8.2 The bituminous material shall be applied by a bituminous distributor that has been calibrated for had the transverse andlongitudinal application rate rates determined by Practice D2995.D5360 1528.3 The aggregate application rate shall be estima
28、ted by using Practice D1369 as a guide.8.4 The aggregate shall be applied by a self-propelled mechanical spreader or other aggregate spreading device that is capableof uniformly spreading the aggregate at the desired rate and width. The spreader shall be calibrated to apply the quantity of coveraggr
29、egate indicated by the design requirements for a given project. This calibration can be accomplished with several sheets ofcanvas, canvas or other similar material, each being one square yard (square metre), and a suitable scale. This is done in a mannersimilar to Test Method D5624 for bituminous di
30、stributors.9. Precautions9.1 Surface treatment operations should not be carried out during periods of cold or wet weather, or both. The surface shall beclean and dry while performing the work.9.1.1 The air temperature should be at least 50F (10C) in the shade and rising before starting the operation
31、. The operationshould 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, or when rain is threatening.10. Method of Sampling and Testing10.1 Sample materials in accordance with Practice D140.10.2 Calibrate application eq
32、uipment in accordance with the following standards:10.2.1 Determining Application Rate and Residual Application Rate of Bituminous DistributorsPractice D2995.10.2.2 Determining the Transverse Aggregate Spread Rate for Surface Treatment ApplicationsTest Method D5624.11. Construction Procedure11.1 Pat
33、ch potholes, fill cracks, and repair damaged areas in existing pavement or consolidated base.11.2 The surface to be covered should be cleaned with a rotary broom or other approved means.11.3 Spray bituminous material at the specified rate and proper temperature for type and grade of material. The re
34、commendedviscosity range for spraying is 20120 cSt, kinematic (approximately 1060 SFS). A guide to the range that encompasses thecorrect spraying temperature for various types and grades of material can be found in the appropriate standard for the material (thatis, asphalt cement,binder, cutback asp
35、halt, emulsified asphalt, road tar).NOTE 6The flash point of some grades of bituminous materials is below 250F (121C); therefore, caution must be used when applying heat to thesematerials.11.4 Spread cover aggregate at the specified rate immediately behind the bituminous material spray application t
36、o achievemaximum possible chip wetting and embedment depth. This is essential in the case of asphalt cementbinder and road tar becauseof the rapid increase in viscosity with cooling, and is greatly desirable in the case of emulsified asphalt emulsions and cutbackasphaltsasphalt to maximize the menis
37、cus effect. The cover aggregate should be placed on the bituminous material within 2 minof the bituminous application.11.5 Roll the surface immediately after application of the cover aggregate, aggregate to ensure embedment, preferably with apneumatic-tired roller, to seat chips in the bituminous me
38、mbrane. The speed of the roller should not exceed 5 mph. Depending onenvironment conditions, type and amount of bituminous material, three (3) passes of a 12 to 15-ton pneumatic-tired roller arenormally used. Initial rolling of the aggregate should occur within 5 min of the application of the bitumi
39、nous material, and the finalof the three rolling coverages should be completed within 3015 min.11.6 Control traffic speed until bituminous material has set. It is recommended that traffic speed not exceed 20 mph for a periodof 4 h after placement of the surface treatment.11.7 For multiple surface tr
40、eatments, repeat steps 11.3 11.6. Successive applications should be applied only after the previousbituminous surface treatment has set and cured, usually one day. Remove excess aggregate before applying the second or thirdlayer of surface treatment.D5360 15312. Keywords12.1 chip seal; multiple surf
