ASTM D8139-23

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D8139 − 17 D8139 − 23
Standard Specification for
Semi-Rigid, Closed-Cell Polypropylene Foam, Preformed
Expansion Joint Fillers for Concrete Paving and Structural
Construction
This standard is issued under the fixed designation D8139; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers preformed expansion joint fillers made from closed-cell polypropylene foam materials having
suitable compressibility, recovery from compression, nonextruding, and weather-resistant characteristics.
1.1.1 Type I, closed-cell polypropylene foam.
1.2 These joint fillers are intended for use in concrete pavements in full-depth joints. There are several variations in size with
1 3 1
typical thicknesses of ⁄2 in. (12.7 mm), ⁄4 in. (19.05 mm), and 1 in. (25.4 mm); typical widths of 3 ⁄2 in. (88.9 mm), 4 in.
(101.6 mm), 5 in. (127 mm), 6 in. (152.5 mm), 7 in. (177.8 mm), 8 in. (203.2 mm), or 48 in. (1.2 m) sheet; and typical lengths of
5 ft (1.52 m) and 10 ft (3.05 m).
1.3 The values stated in inch-pound units are to be regarded as the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Materials and Manufacture
3.1 Type I, Closed-Cell Polypropylene Foam—These fillers shall be made from extruded foam polypropylene, and their preformed
cross section shall be closed-cell.
4. Physical Properties
4.1 Compressive Strength—The load required to compress the test specimen to 50 % of its original thickness before test shall not
be less than 30 psi nor greater than 60 psi.
4.2 Recovery—After compressing the test specimen to 50 % of its original thickness before test, the load shall be released; and
10 min after release of the load, the specimen shall have recovered to at least 80 % of its thickness before test.
4.3 Extrusion—When a ⁄2-in. (12.7-mm) in. (12.7 mm) thick test specimen is compressed to 50 % of its original thickness with
three of its edges restr
