ASTM - D5249

Standard Specification for Backer Material for Use with Cold- and Hot-Applied Joint Sealants in Portland Cement Concrete and Asphalt Joints

active, Most Current
Organization: ASTM
Publication Date: 1 December 2010
Status: active
Page Count: 4
ICS Code (Binders. Sealing materials): 91.100.50
scope:

This specification covers backer material for cold- and hot-applied joint sealant for use in portland cement concrete or asphalt pavement joints.

This specification establishes basic requirements for sealant backer material, either in rod or strip form, that can withstand the temperature of hot- or cold-applied sealants without excessive deformation.

Sealant backer material serves one or more of the following purposes:

Limits the amount and depth of sealant applied to a joint,

Acts as a barrier interface to prevent backside adhesion (bond breaker), and

Provides a form to assist the sealant in developing a shape factor.

The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information purposes only.

The following safety hazards caveat pertains only to the test methods described in this specification. 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.

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.
