ASTM E670

ASTM E670 is the ASTM standard for testing side force friction on paved surfaces using the Mu-Meter. It provides a structured way to evaluate how a paved surface resists side-force loading, which is important for understanding surface performance in practical conditions. As a technical document, it supports more consistent testing, comparison, and reporting when friction characteristics on paved surfaces need to be measured with a defined method.

What is ASTM E670?

ASTM E670, titled

Standard Test Method for Testing Side Force Friction on Paved Surfaces Using the Mu-Meter

, defines a test method centered on measuring side force friction on paved surfaces. The standard is tied to the use of the Mu-Meter, which indicates a specific testing approach and equipment-based procedure. In product and compliance settings, this standard helps establish a common basis for evaluating surface friction behavior in a repeatable way, rather than relying on informal observation or inconsistent site practices.

Where is ASTM E670 used?

This standard is commonly used where paved surfaces must be evaluated for friction-related performance using a defined test method. It is relevant in testing and quality control workflows that involve pavement condition assessment, surface verification, or performance comparison. ASTM E670 may also support procurement or maintenance decisions when a paved surface needs to be checked against a consistent testing approach. The Mu-Meter-based method makes it especially useful in technical inspections where repeatability matters.

Why is ASTM E670 important?

ASTM E670 matters because it helps bring consistency to side force friction testing on paved surfaces. When friction measurements are needed for evaluation, documentation, or comparison, a recognized ASTM method can reduce ambiguity and improve confidence in results. It may also support risk reduction by giving engineers, inspectors, and buyers a clearer basis for assessing surface performance. For organizations that depend on reliable pavement testing, ASTM E670 helps align testing practice with a defined standard.
