|Publication Date:||1 December 2009|
|ICS Code (Binders. Sealing materials):||91.100.50|
|ICS Code (Road construction materials):||93.080.20|
1.1 The viscosity-temperatur
1.2 The chart is suitable for original asphalt cements and for asphalts recovered from laboratory aging tests or extracted from pavements.
1.3 The chart is based on a viscosity-temperatur
1.4 The range of the chart is sufficient for roofing asphalts.
1.5 The range of the chart is sufficient for liquid asphalts (bitumens) whose viscosity exceeds 0.01 Pa.S (10 centipoise).
1.6 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 non-conformance with the standard.
