Figure 4.28: CAT Hand Roller 65 Mix M2a Mix M2b
Both systems were correctly defined by this test as quick set; the aggregate effect was clearly distinguished. Compaction did consolidate the surface to some extent but an analysis of the data indicates that there is no significant difference between the compacted and non-compacted specimens and as a result compaction is not recommended. This is illustrated in Figure 4.29. wet Loss g 300 250 200 150 100 50 0 Figure 4.29: Effect of Compaction on M2 Mixes (Wet Loss Method) 4.2.4 Effect of Tack Coat Effect of Compaction Wet Loss at 1 Hour Cure M2a Mix M2b (60 Min Cure at 70°F (25°C) 70% Humidity) Tack coat was applied on the metal base using a brush. The base plate was covered with a thin, even coat of emulsion. The tack coat was allowed to dry to the touch. As illustrated in Figure 4.30, the tack seemed to reduce losses perhaps by holding the sample firmly and preventing shear at the base. 66 Not compacted Compacted
