AASHTO M 261-18 PDF Download

The AASHTO M 261-18 standard specifies the requirements for a specific type of tire, known as the rib tire, that is used to conduct frictional-property tests on special-purpose pavements. The purpose of this standard is to ensure consistency and accuracy in the evaluation of tire-pavement friction.

The specification references ASTM E 867 for terminology, indicating that the terminology used in the AASHTO standard is in line with the definitions provided by ASTM E 867. This helps to ensure clear communication and understanding within the industry.

Additionally, the standard aligns with ASTM E 501-08 in terms of general requirements, with the exception of terminology, figures, and the use of SI units. This alignment with ASTM standards promotes consistency and compatibility with other industry standards.
