ASTM D3205-86 (R1991) PDF Download

ASTM D3205-86 (R1991) is a standard test method used to determine the viscosity of asphalt cements using a cone-plate viscometer. This method is applicable to materials with viscosities in the range from 10 to 10 P (10 to 10 Pa[dot]s), making it suitable for use at temperatures where the viscosity falls within this range. The shear rate can vary between approximately 10 to 10 s, and the method is suitable for determining the viscosity of materials with both Newtonian and non-Newtonian flow properties.

Overall, this standard provides a standardized procedure for measuring the viscosity of asphalt cements, which is important for assessing their quality and performance in asphalt applications. By using a cone-plate viscometer, this test method allows for accurate measurement of the viscosity, which in turn provides valuable information for the selection and design of asphalt mixes and pavements. The viscosity of asphalt cements influences their flow characteristics and ability to coat aggregates, and therefore, is a crucial property for ensuring the proper performance of asphalt materials.
