Significance and Use | ||||||||||
4.1?This test method indicates approximate change in properties of asphalt during conventional hot-mixing at about 302 ?F (150 ?C) as indicated by viscosity and other rheological measurements. It yields a residue which approximates the asphalt condition as incorporated in the pavement. If the mixing temperature differs appreciably from the 302 ?F (150 ?C) level, more or less effect on properties will occur. This test method can also be used to determine mass change, which is a measure of asphalt volatility. Note 1:?The quality of results produced by this standard is
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 guidance
provides a means of evaluating and controlling some of those
factors.

1. Scope | ||||||||||
1.1?This test method is intended to measure the effect of heat and air on a moving film of semi-solid asphaltic materials. The effects of this treatment are determined from measurements of the selected properties of the asphalt before and after the test. 1.2?The values stated in inch-pound units are to be regarded as the standard. 1.3?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. 1.4?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. 1.5?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. |
