ASTM E2133

ASTM E2133 is the ASTM standard for using a rolling inclinometer to measure longitudinal and transverse profiles of a traveled surface. It provides a technical framework for collecting surface profile data in a controlled, repeatable way, helping users evaluate how a traveled surface changes along and across its path. This makes the standard relevant for engineering review, quality control, and performance assessment when profile measurement consistency matters.

Purpose of ASTM E2133

The purpose of ASTM E2133 is to define a test method for measuring the longitudinal and transverse profiles of a traveled surface with a rolling inclinometer. By establishing a common approach to data collection, the standard helps support comparable results across projects and testing programs. It is generally used when a surface profile must be described with consistent measurement practice, allowing users to document conditions, compare sections, and support technical decisions based on the same test method.

Common use cases of ASTM E2133

This standard is commonly used where traveled surfaces need profile measurement for evaluation, documentation, or acceptance-related review. It may apply to roadways, pavements, or other engineered surfaces where longitudinal and transverse profile information is useful. ASTM E2133 is also relevant in workflows that depend on rolling inclinometer equipment and repeatable surface testing procedures. In practice, it supports organizations that need a standardized method for recording surface shape and comparing results over time or between locations.

Why ASTM E2133 matters

ASTM E2133 matters because profile measurement is only useful when the method is consistent and defensible. A standardized approach helps reduce variation in testing practice, which supports better procurement decisions, quality control, and compliance-oriented documentation. For organizations evaluating a traveled surface, the standard can improve confidence in results by aligning measurement technique and reporting expectations. ASTM E2133 also helps reduce ambiguity when multiple parties need to rely on the same technical data.
