LBT-1A22 Petroleum Product Asphalt Kinematic Viscosity Tester (Reverse Flow Capillary Method)

Description

Product Introduction

1. This method is applicable to the determination of viscous petroleum asphalt, liquid petroleum asphalt, and their distillation residues using a capillary viscometer.

The kinematic viscosity of the residue.

2. Unless otherwise specified, the test temperatures are 135°C (for viscous petroleum asphalt) and 60°C (for liquid petroleum asphalt). For

Obtain the viscosity–temperature curve of viscous petroleum asphalt at high temperatures; when determining the isoviscous temperature as the construction temperature, it is advisable to use…

120°C, 150°C, and 180°C were used as the test temperatures.

In the industry standard JTG 3410-2025, “Test Procedures for Asphalt and Asphalt Mixtures in Highway Engineering,” T 0619-2025 specifies the “Kinematic Viscosity of Asphalt (Capillary Method).”
