·Washing aggregate sludge is a silt clay waste that is generated in the classification cycle of sand and gravel The accumulation of washing aggregate sludge on rafts is the most used method because it is the most economical although this process involves numerous limitations and disadvantages Blanco 2004
Barrels have been used to wash aggregates since the very early days of washing plants Two types of barrels are available in the market washing barrels and scrubber barrels Washing barrels turn at a relatively slow speed and are usually incorporated where the feed material does not need intensive attrition to clean it
·A total of fifteen types of LWAs were manufactured in a previous study [8] from which 11 different types were selected Table 1 Aggregates of type 3 were manufactured with a 75 25 proportion wt % of washing aggregate sludge fly ash WS FA whereas types 2 were prepared using a 50 50 were manufactured with a ratio
·The aggregate s angular shape and rough textured surface are critical in determining the deformation resistance of the SMA at high temperatures Recycled concrete aggregates have a more angular shape and rougher particles than the normal aggregate and thus have higher internal friction that increased the rutting resistance Kuo and Du 2010
