AASHTO M 213-01 (2019) PDF Download

AASHTO M 213-01 (2019) is a standard specification that addresses preformed expansion joint fillers used in concrete paving and structural construction. These fillers are specifically designed to have minimal extrusion and to exhibit significant recovery after being compressed. This standard outlines the requirements for the performance and composition of these fillers in order to ensure their suitability and effectiveness in construction projects.

The purpose of preformed expansion joint fillers is to provide a flexible and resilient material that can accommodate the movement and expansion of concrete structures. These fillers are placed in the joints between concrete slabs or structures and help to prevent the ingress of debris, water, and other substances that could potentially cause damage or deterioration. By filling these joints, the fillers also contribute to the overall stability and longevity of the concrete construction.

AASHTO M 213-01 (2019) establishes the criteria for the physical properties, such as recovery and extrusion, that these fillers must meet in order to be considered suitable for use. It also outlines the testing and evaluation methods that should be employed to assess the compliance of these fillers with the specified requirements.
