It is easily compressed and has a recovery of 95% or more of the original thickness and a density of not less than 480.56 kg\/m\u00b3 (30 lb.\/ft.\u00b3).<\/p>\n<p><strong>USES<\/strong><\/p>\n<p>SPONGE RUBBER EXPANSION JOINT is frequently used on bridge structures and sewage treatment plants that undergo rapid changes in temperature. Because of its excellent recovery capability during wide temperature variations, SPONGE RUBBER EXPANSION JOINT is used around supporting pillars, drains, hydrants, and lamp and sign posts, as well as in isolation applications or between materials having dissimilar coefficients of expansion.<\/p>\n<p><strong>FEATURES\/BENEFITS<\/strong><\/p>\n<ul>\n<li>High resiliency with excellent recovery after compression.<\/li>\n<li>Easy to handle and install.<\/li>\n<li>Offers isolation capabilities.<\/li>\n<\/ul>\n<p><strong>PACKAGING<\/strong><\/p>\n<table class=\"table\" width=\"100%\">\n<tbody>\n<tr>\n<td width=\"109\">Thickness Widths<\/td>\n<td width=\"84\">Slab<br \/>\nWidths<\/td>\n<td width=\"91\">Standard Lengths<\/td>\n<\/tr>\n<tr>\n<td width=\"109\">6.4 mm (1\/4&#8243;)<br \/>\n9.5 mm (3\/8&#8243;)<br \/>\n12.7 mm (\u00bd&#8221;)<br \/>\n19.1 mm (\u00be&#8221;)<br \/>\n25.4 mm (1&#8243;)<\/td>\n<td width=\"84\">914.4 mm (36&#8243;)<\/td>\n<td width=\"91\">3.05 m<br \/>\n(10&#8242;)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>SPECIFICATIONS\/STANDARDS <\/strong><\/p>\n<ul>\n<li>AASHTO M 153, Type 1<\/li>\n<li>ASTM D1752, Type 1<\/li>\n<li>Corps of Engineers CRD-C 509, Type I<\/li>\n<li>FAA Specification Item P-610-2.7<\/li>\n<li>Federal Specification HH-F-341 F, Type II, Class A<\/li>\n<\/ul>\n<p><strong>TECHNICAL DATA<\/strong><\/p>\n<table class=\"table\" width=\"100%\">\n<tbody>\n<tr>\n<td width=\"138\"><strong>PROPERTY<\/strong><\/td>\n<td width=\"128\"><strong>TYPICAL TEST RESULTS<\/strong><\/td>\n<td width=\"133\"><strong>TEST METHOD<\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"138\">Standard Colour:<\/td>\n<td width=\"128\">Grey<\/td>\n<td width=\"133\"><strong>\u00a0<\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"138\">Density:<\/td>\n<td width=\"128\">480 kg\/m<sup>3<br \/>\n<\/sup>30 lb.\/ft.<sup>3 <\/sup><\/td>\n<td width=\"133\">ASTM D545<\/td>\n<\/tr>\n<tr>\n<td width=\"138\">Compression Force Deflection 50% Compression:<\/td>\n<td width=\"128\">0.3 MPa<br \/>\n(50 psi)<\/td>\n<td width=\"133\">ASTM D545<\/td>\n<\/tr>\n<tr>\n<td width=\"138\">Recovery, Thickness Recovered, Compressed 50% at RT for 10 min:<\/td>\n<td width=\"128\">90%<\/td>\n<td width=\"133\">ASTM D545<\/td>\n<\/tr>\n<tr>\n<td width=\"138\">Extrusion, Compressed 50% with 3 edges restrained:<\/td>\n<td width=\"128\">6.4 mm<br \/>\n(0.250\u201d)<\/td>\n<td width=\"133\">ASTM D545<\/td>\n<\/tr>\n<tr>\n<td width=\"138\">Temperature Range:<\/td>\n<td width=\"128\">-84\u00b0 to 71\u00b0 C<\/td>\n<td width=\"133\"><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>APPLICATION <\/strong><\/p>\n<p>The type of control joint and spacing used will vary with each project according to the type of structure, climatic conditions, and anticipated stresses in the concrete. Thinner joints of 6.4 mm (1\/4&#8243;), 9.5 mm (3\/8&#8243;), or 12.7 mm (1\/2&#8243;), spaced at frequent intervals, offer greater control than thicker joints spaced at greater intervals. The basic objective is to provide ample room for the concrete to expand or contract without creating damaging stresses. Expansion joints should be positioned against forms at interrupting objects or columns and against abutting structures prior to the placement of the concrete. SPONGE RUBBER EXPANSION JOINT should be recessed 12.7 mm (1\/2&#8243;) below the concrete surface to accept the joint sealant.
