ASTM D545-19 PDF Download

The ASTM D545-19 standard provides a set of test methods for evaluating the physical properties of preformed expansion joint fillers. These fillers are used in concrete construction to accommodate movement and prevent damage caused by thermal expansion.

The standard includes several test methods to assess the performance of the joint fillers. These methods cover properties such as expansion in boiling water, recovery and compression, extrusion resistance, boiling in hydrochloric acid, asphalt content, water absorption, and density. Each method is described in section 7 of the standard.

The results obtained from these tests can indicate the joint filler's ability to continuously fill the expansion joint, resist extrusion, and recover after load release. The asphalt content is a measure of durability and life expectancy for fiber-type joint fillers, while resistance to water absorption and hydrochloric acid boiling are relative measures of durability for cork-type fillers.

It is important to note that the quality of test results relies on the competence of personnel performing the procedures and the calibration and maintenance of the equipment used. Compliance with Specification D3666 is recommended as a guideline for evaluating and controlling the testing process. However, it is cautioned that compliance with this specification alone does not guarantee reliable results, as they depend on various factors.
