4.2 The test method can quantify the influence of some formulation parameters on setting time and cohesion build up (such as variations of the mix components or the environmental temperature and/or humidity conditions while laying). 5.0 APPARATUS 5.1 The CAT system set-up is illustrated in Figure B.1 5.2 Planetary type mechanical mixer, such as Hobart N-50 equipped with a dual wheel abrasion head, quick-clamp mounting plate, and flat bottom metal pan. See Figure 5.1. 5.2.1 Ridged Wheels: 4 inches (100 mm) diameter with 0.8 inches (20.3 mm) contact width. 5. 2.2 Wheel hardness of 75 and 95 (durometer reading) foot. 5. 2.3 Abrasion head should weigh between 1100 g and 1150 g. 5. 2.4 Aluminum abrasion pan, approximately 2.16 inches (55 mm) high with an inside diameter approximately 11 inches (279.4 mm). Figure B.1: Testing Apparatus 5.3 Stainless steel or aluminum casting plates: 0.8 inches (2 mm) thick, 10.8 inches (274.3 mm) diameter. 113
5.4 Suitable specimen casting mold with .55 inches (14 mm) depth and 9.8 - 9.9 inches (250-252 mm) inside diameter. A raised lip mold is preferred but a flat surface polymethyl methacrylate or equivalent mold is satisfactory. 5.5 Mold strike-off apparatus, such as a wooden dowel, with minimum dimensions: 0.78 - 17.7 inches (20 mm diameter by 450 mm long). 5.6 Scales, with capacity of 2000.0 g, accurate to +/- 0.1 g. 5.7 Wooden prop block or device to support the pan and mounting plate assembly during the test. 5.8 Suitable rust-resistant mixing containers and spoons. Additionally, plate removal device with tapered flat tip (for example, a paint can lid opening tool), as pictured in Figure B.2, is needed for carefully placing and removing specimen plates into and from the abrasion pan. Figure B.2: Plate Removal Device 5.9 Constant temperature water bath controlled at specified temperatures. 5.10 Absorbent paper towels, single fold, CS Scott or equivalent. 114
