ASTM D242-2019 pdf free download.Standard Specification for Mineral Filler for Asphalt Mixtures
1. Scope
1.1 This specification covers mineral filler added as a separate ingredient for use in asphalt mixtures. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with 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 international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 For definitions of terms used in this standard, see Terminology D8.
4. General Description
4.1 Mineral filler shall consist of finely divided mineral matter such as rock dust, slag dust, hydrated lime, hydraulic cement, fly ash, loess, or other suitable mineral matter. At the time of use, it shall be sufficiently dry to flow freely and essentially free from agglomerations.
5. Physical Requirements
5.1 Mineral filler shall be graded within the following limits:5.2 Mineral filler prepared from rock dust, slag dust, loess, and similar materials shall be essentially free from organic impurities and have a plasticity index not greater than 4. N OTE 1—Plasticity index limits are not appropriate for hydrated lime and hydraulic cement.
6. Methods of Sampling and Testing
6.1 Sample the mineral filler according to Practice C50/ C50M or C183/C183M, or Test Methods C311/C311M, which- ever is most appropriate for the material being sampled, except as noted in 6.1.1. 6.1.1 Obtain samples at random intervals not to exceed each 300 tons of material as delivered. 6.2 The minimum size of field samples shall be 5.0 kg [11 lb]. Reduce the field sample to a minimum size of 2.5 kg [5 lb] for testing. 6.3 Determine the grading of the material by Test Method D546. 6.4 Determine the plasticity index by Test Methods D4318.
