This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1906 edition. Excerpt: ... soft brick can be detected and picked-out as being those which remain wet after the hard bricks have dried. JOINT FILLERS. No filler has yet been found that is perfect, and there are wide differences of opinion as to the best. Sand filler is cheap and allows the brick to be readily taken up and relaid, but it also allows the edges and corners of the bricks to chip and become rounded, and permits the bricks to settle at soft spots of subgrade. Portland Cement Grout of equal parts by bulk, of loose cement and fine sand, if properly made and applied, is better, and there are patented mixtures which are combinations of iron-slag and cement ground together, and which are equally good or better. Grout is irregular and worthless, unless the sand used is so fine as to remain in suspension, and such sand is not easy to obtain: grout should be poured into place, but is sometimes flushed broadly over the surface and swept into the joints. Grout makes it difficult to take up and relay the brick, but it can, if properly made and applied, perfectly protect their edges and corners and thus preserve a smooth surface, which is most desirable. For some reason which is not clear, the pavements with cement grout joints seem to be the most noisy. Paving Cement makes an elastic joint which in some cases is best, although it costs more than grout. The Cost of joint fillers for brick per square yard of pavement: Sand, 2 to 4 cents; Portland cement grout, 8 to 12 cents; paving cement, 10 to 12 cents; asphalt filler, 14 to 16 cents. 96 JOINT FILLERS. usual composition consists of 100 parts by weight of No. 4 coal-tar, three parts residuum oil and twenty parts refined asphalt, kept and used at a temperature of 3000 Fh., meantime carefully avoiding over-heating it.
