【国外标准】 Standard Specification for Hot-Mixed, Hot-Laid Bituminous Paving Mixtures (Withdrawn 2009)

This specification covers hot-mixed, hot-laid asphalt, tar, emulsified asphalt, and recycled bituminous paving mixtures for base, binder, leveling, and surface courses. The aggregates, mineral fillers, bitumen (asphalt cement, tar cement, or emulsified asphalt as appropriate), and bituminous paving mixtures shall be in accordance to specified consistency and compositions. Products shall be sampled, and undergo sieve analysis and other forms of test methods as appropriate for extracting bitumen content, specific gravity, plasticity index, percentage of coated particles, recovery of extracted asphalt, penetration of recovery asphalt, air voids, and absolute viscosity.1.1 This specification covers hot-mixed, hot-laid asphalt, tar, emulsified asphalt, and recycled bituminous paving mixtures for base, binder, leveling, and surface courses.1.2 The values stated in SI units are to be regarded as the standard. Combining values from the two systems may result in nonconformance with the standard.1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
