(MACTEC) is pleased to provide laboratory testing services <br />for Qwick Kurb, Inc. The following briefly summarizes our understanding of the scope of work, and <br />presents the test results. <br />As requested, we performed compressive strength testing on a Qwick Kurb Product, Premolded Curbs <br />made from recycled cable scrubs using representative section of the product. The samples were shipped to <br />our laboratory in March 2008. Photos I fund 2 show one of the samples as received, We performed a <br />compressive strength test by placing the sample in a compressive strength testing machine used for <br />concrete compressive strength tests (Forney Model LT-8063-D2). We loaded the sample until it reached <br />the maximum load and used this maximum load and the contact area (area between the load plate and the <br />top of the sample) to calculate the nominal compressive strength in pound per square inch. Table 1 <br />summarizes the results. We also monitored the rebound for a day after the sample was loaded. Photos 3 <br />and 4 show the tested sample after complete rebound compared with the untested sample. After 24 hours, <br />the tested sample rebounded to within 90016 of its original height, <br />Table I. <br />Sample No. <br />Contact Area <br />(inches') <br />Peak Load <br />(lbs) <br />Compressive Strength <br />(psi) <br />4 <br />14.95 <br />56000 <br />3746 <br />We appreciate the opportunity of serving your laboratory testing needs. If you have questions, or if we <br />can be of further service, please contact us. <br />Sincerely, <br />MACTEC Engineering and Consulting, Inc. <br />40U(9j� <br />Harry Johnson <br />Geotechnicai Laboratory Manager <br />dang <br />Principal/Manager of Labor ry Services <br />MACTEC Enginearing and Consulting, Inc. <br />386 Plasters Avenue, NE • Atlanta, 4A 30324 6 Phone: 404-873-4761 • Fax: 404.817.0221 <br />www. rnactec.corn <br />
