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 emulsified asphalts, cutback asphalts, or combinations thereof.
Note 1: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
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. 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 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.6 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. This procedure may involve hazardous materials, operations, and equipment.
1.7 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.
