1.1 本规程涵盖沥青橡胶斗篷密封，其定义为在现有路面表面涂上沥青橡胶密封层，然后涂上传统的II型或III型稀浆密封。 注1: 沥青橡胶密封层也称为应力吸收膜（SAM），它由沥青橡胶膜密封和预涂骨料碎片组成。 1.2 沥青橡胶斗篷密封通常用于延长低至中等交通量和中等破损沥青路面的使用寿命。现有路面条件可用于确定沥青橡胶粘合剂和骨料的应用率以及骨料级配。条件相对较差的路面将需要具有更高粘结剂应用率的较粗骨料。 1.3 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值可能不是完全相等的； 因此，每个系统应独立使用。将两个系统的值结合起来可能会导致不符合标准。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 3.1 本规程中所述的程序用于设计和建造沥青橡胶斗篷密封件，该密封件将在低至中等交通量以及路面因阻塞而受损时提供磨耗层- 仅由路面老化或反射裂缝引起的类型裂缝（不包括由于重复的重型轴荷载而产生的疲劳裂缝的明显迹象）。 注2: 块体开裂在实践中有定义 D6433 看见 附录X1 例如由于老化导致的块破裂。

1.1 This practice covers asphalt-rubber cape seal, which is defined as the application of an asphalt-rubber seal coat placed onto an existing pavement surface, followed by the application of a conventional Type II or III slurry seal. Note 1: An asphalt-rubber seal coat is also known as a stress absorbing membrane (SAM), which consists of an asphalt-rubber membrane seal followed by the application of pre-coated aggregate chips. 1.2 An asphalt-rubber cape seal is commonly used to extend the service life of low to medium trafficked and moderately distressed asphalt-surfaced pavements. The existing pavement condition can be used to determine the application rates for the asphalt-rubber binder and aggregate as well as the aggregate gradation. Pavements in relatively poor condition will require a coarser aggregate with a higher binder application rate. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 3.1 The procedure described in this practice is used to design and construct an asphalt-rubber cape seal that will provide a wearing course when subjected to low to medium traffic volumes and where the pavement distress is due to block-type cracking resulting from pavement aging or reflective cracking only (not where there are clear indications of fatigue cracking due to repeated heavy axle loads). Note 2: Block cracking is defined in Practice D6433 . See Appendix X1 for an example of block cracking due to aging.
