Petroleum asphalts for heavy traffic road pavement
1 Scope
This standard specifies the technical requirements and test methods as well as packaging, marking, storage and transportation of the petroleum asphalts for heavy traffic road pavement which are produced by appropriate process with the petroleum as the raw material.
This standard is applicable to petroleum asphalts for heavy traffic road pavement (e.g., expressway, first-class highway, urban expressway, arterial road, etc.) and is also applicable to other highways at various classes, urban roads, airport pavements, etc. as well as petroleum asphalts used as raw materials of emulsified asphalts, cutback asphalts and modified asphalts.
