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.
