Long Term Pavement Performance Project Laboratory Materials Testing and Handling Guide

Protocol H04L
Viscosity of Asphalts (AE06S)

This LTPP protocol covers the determination of absolute viscosity. It is intended to be used on asphalt cements extracted from cores taken as a part of the SPS-3 studies.

The absolute viscosity of asphalt cements shall be determined by vacuum capillary viscometers at 60°C (140°F). The test shall be performed in accordance with AASHTO T202-89I, Standard Method of Test for Viscosity of Asphalts by Vacuum Capillary Viscometer, except as designated below. Asphalt Institute viscometers shall be used.

The results will be recorded on LTPP Test Sheet H03. Comments shall include LTPP standard comment code(s) as shown in Section 4.3 of this Guide, and any other note as needed. An additional code for special comments associated with the testing is given below.
