Foundation/AnchoringConcrete InstallationsFor concrete installations, the REACT 350 ® II system should be installed only on an existing orfreshly placed and cured concrete base (28 MPa [4000 psi] minimum). Orientation of theconcrete base and the attenuator must comply with the project plans or as otherwisedetermined by the resident project engineer or appropriate highway authority.Recommended dimension and reinforcement specifications for new concrete pads can be foundon the standard drawings.Asphalt InstallationsFor asphalt installations in construction zones, REACT 350 ® II system may only be assembledwith a Tension-Strut Backup. Assemblies on asphalt must provide a minimum of 76 mm [3”]layer of asphalt over a minimum of 76 mm [3”] layer of Portland Cement concrete, 152 mm [6”]layer of asphalt over 152 mm [6”] layer of subbase, or 203 mm [8”] layer of asphalt with nosubbase. 460 mm [18”] threaded rods, installed with the two-part MP-3 ® grout, must be used forthese foundations.Important: Systems mounted on asphalt must be replaced and mounted onfresh, undisturbed asphalt if more than 10% of anchors are found to be loose,broken, or show signs of pull out. If 10% or fewer anchors are damaged, replacethe damaged anchors in the existing asphalt. Anchor bolts used on systemsmounted on asphalt must be inspected every 6 months. See Post ImpactInstructions and Maintenance and Repair instructions in the REACT 350 ® IIAssembly Manual for details.The REACT 350 ® II system may be installed on any of the following foundations using thespecified anchorage:Foundation A: Concrete Pad or RoadwayFoundation: 150 mm [6”] minimum depth Portland Cement Concrete (P.C.C.)Anchorage: MP-3 ® with 180 mm [7”] studs 140 mm [5 1/2”] embedmentFoundation B: Asphalt over P.C.C.Foundation: 76 mm [3”] minimum asphalt concrete (A.C.) over 76 mm [3”] minimum P.C.C.Anchorage: Length of anchor required is 460 mm [18”] 420 mm [16 1/2”] embedmentFoundation C: Asphalt over SubbaseFoundation: 150 mm [6"] minimum A.C. over 150 mm [6”] minimum Compacted Subbase(C.S.)Anchorage: MP-3 with 460 mm [18"] studs 420 mm [16 1/2”] embedmentFoundation D: Asphalt OnlyFoundation: 200 mm [8”] minimum A.C.Anchorage: MP-3 with 460 mm [18”] studs - 420 mm [16 1/2”] embedmentFoundation Specificationsfor Foundations A, B, C, and D mentioned above:www.energyabsorption.com Revision A July 2013www.highwayguardrail.com 17 All rights in copyright reserved
