those described above. Dimensions should be measured at right angles to each other in order to keep the recommended distances from being exceeded in either direction. Expansion joint material should be placed along fixed objects such as drains or adjacent walls. Suggested placement of expansion joints for mortared brick paving are shown in Fig. 10.
Expansion joint filler materials must be highly compressible and be durable when exposed to weather or abrasion. Generally, paving joint fillers made of materials such as polyethylene or premolded cellular elastomeric rod are acceptable. Materials which do not easily compress, such as cork or asphaltic control joint fillers, are not appropri-
