    1、Designation: D 6704 01Standard Test Method forDetermining the Workability of Asphalt Cold Mix PatchingMaterial1This standard is issued under the fixed designation D 6704; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of

    2、last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method provides a procedure for determinationof the workability of asphalt cold mix patching materials.1.2

    3、This test method is applicable to asphalt cold mixpatching materials that will be stockpiled or packaged incontainers, subjected to different climatic conditions, and laterused for roadway patching operations.1.3 Precision and bias for this test method has not beendetermined, therefore, this test me

    4、thod should not be used forpurchasing purposes.1.4 This procedure may involve hazardous materials, opera-tions, and equipment. This standard does not purport toaddress all of the safety concerns, if any, associated with itsuse. It is the responsibility of the user of this standard toestablish approp

Significance and Use5.1 This test method may be used to generate informationconcerning the potential char

    10、acteristics of handling, placing,compaction, and performance of an asphalt cold mix.5.2 Workability is one of the main factors that influences thesuitability and ultimately the performance of asphalt cold mixsuitability for use as a roadway patching material.5.3 This test method is applicable to asp
