1.1 This specification covers backer material for cold- and hot-applied joint sealant for use in portland-cement concrete or asphalt-pavement joints. 1.2 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. 1.3 Sealant backer material serves one or more of the following purposes: 1.3.1 Limits the amount and depth of sealant applied to a joint, 1.3.2 Acts as a barrier interface to prevent backside adhesion (bondbreaker), and 1.3.3 Provides a form to assist the sealant in developing a shape factor. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information purposes only. 1.5 The following safety hazards caveat pertains
only to the test methods described in this specification.
