DocuSign Envelope ID:070B6BC7-CDE2-4AO8-BE62-07FA6BFDO53B <br /> 11/20/2020 <br /> C. Install joint-sealant backings to support joint sealants during application and at position required <br /> to produce cross-sectional shapes and depths of installed sealants relative to joint widths that <br /> allow optimum sealant movement capability. <br /> 1. Do not leave gaps between ends of joint-sealant backings. <br /> 2. Do not stretch,twist,puncture, or tear joint-sealant backings. <br /> 3. Remove absorbent joint-sealant backings that have become wet before sealant application <br /> and replace them with dry materials. <br /> D. Install joint sealants immediately following backing installation, using proven techniques that <br /> comply with the following: <br /> 1. Place joint sealants so they fully contact joint substrates. <br /> 2. Completely fill recesses in each joint configuration. <br /> 3. Produce uniform, cross-sectional shapes and depths relative to joint widths that allow <br /> optimum sealant movement capability. <br /> E. Tooling of Nonsag Joint Sealants:Immediately after joint-sealant application and before skinning <br /> or curing begins, tool sealants according to the following requirements to form smooth,uniform <br /> beads of configuration indicated; to eliminate air pockets; and to ensure contact and adhesion of <br /> sealant with sides of joint: <br /> 1. Remove excess joint sealant from surfaces adjacent to joints. <br /> 2. Use tooling agents that are approved in writing by joint-sealant manufacturer and that do <br /> not discolor sealants or adjacent surfaces. <br /> F. Provide joint configuration to comply with joint-sealant manufacturer's written instructions unless <br /> otherwise indicated. <br /> 3.4 CLEANING AND PROTECTION <br /> A. Clean off excess joint sealant as the Work progresses, by methods and with cleaning materials <br /> approved in writing by joint-sealant manufacturers. <br /> B. Protect joint sealants,during and after curing period,from contact with contaminating substances <br /> and from damage resulting from construction operations or other causes so sealants are without <br /> deterioration or damage at time of Substantial Completion.If,despite such protection,damage or <br /> deterioration occurs, cut out and remove damaged or deteriorated joint sealants immediately and <br /> replace with joint sealant so installations in repaired areas are indistinguishable from the original <br /> work. <br /> 3.5 PAVING-JOINT-SEALANT SCHEDULE <br /> 1. Joint-Sealant Application:Joints within concrete paving and between concrete and asphalt <br /> paving <br /> 2. Joint Location: <br /> a. Joints between concrete and asphalt paving. <br /> 32 13 73 CONCRETE PAVING JOINT Page 3 of 4 <br /> SEALANTS <br />
