Introduction

Standard Name: Standard Method of Test for Evaluation of the Tracking Resistance of Hot-Poured Asphalt Crack Sealant by Dynamic Shear Rheometer (DSR)

Standard Number: AASHTO T 404-23

Scope:

• This test method applies to hot-poured asphalt crack sealant used in the construction and maintenance of roadways as specified in M 338 and R 116.
• It is used to determine the resistance of hot-poured asphalt crack sealant to tracking and deformation at summer temperatures.
• The method covers the determination of flow and shear thinning propensity in hot-poured asphalt crack sealant using a dynamic shear rheometer and creep-recovery tests.
• The quality of results depends on the competence of personnel, equipment capability, calibration, and maintenance. Compliance with R 18 is recommended but does not guarantee reliable results.
