Standard Practice for Preparation of Viscosity Blends for Hot Recycled Bituminous Materials
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This practice covers the procedure for preparation of hot recycled bituminous blends for testing in the laboratory. The procedure involves an iterative trial blend process followed by the preparation of batch blends.
1.2 The batch blends can be used for extensive evaluation such as viscosity, penetration, ductility, aging properties (such as Rolling Thin Film Oven or Thin-Film Oven tests, or both (RTFO/TFO)), composition analysis, solubility analysis, and other user-selected tests.
1.3 This practice assumes that a representative reclaimed asphalt pavement (RAP) sample is extracted and the aged binder recovered using Test Methods D 2172 and Test Method D 1856 (this practice may be modified by using a rotary evaporator which is extensively evaluated in the minutes of the
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 and health practices and determine the applicability of regulatory limitations prior to use.
Significance and Use
A standard procedure for blend preparation is essential to ensure material quality, specification compliance, and procedural uniformity.
