ASTM D6704-08(2015)

Standard Test Method for Determining the Workability of Asphalt Cold Mix Patching Material

SIGNIFICANCE AND USE
5.1 This test method may be used to generate information concerning the potential characteristics of handling, placing, compaction, and performance of an asphalt cold mix.  
5.2 Workability is one of the main factors that influences the suitability and ultimately the performance of asphalt cold mix suitability for use as a roadway patching material.  
5.3 This test method is applicable to asphalt cold mixes manufactured with modified or unmodified asphalt emulsions, cutback asphalts, or combinations thereof.
SCOPE
1.1 This test method provides a procedure for determination of the workability of asphalt cold mix patching materials.  
1.2 This test method is applicable to asphalt cold mix patching materials that will be stockpiled or packaged in containers, subjected to different climatic conditions, and later used for roadway patching operations.  
1.3 The within-laboratory repeatability standard deviation has been determined to be 10 % based on one lab, three test replicates, and two different samples. The between-laboratory reproducibility of this test method is being determined and will be available on or before August 2013. Therefore, this test method should not be used for purchasing purposes.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 This procedure may involve hazardous materials, operations, and equipment. 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.
