The Old-Fashioned Heavy Paving-Block 

 Gives Place to a New Form 



ANEW type of granite block pave- 

 ment, almost as smooth and as 

 easily cleaned as asphalt, is finding favor 

 as a wearing surface for streets of dense 

 traffic. Instead of hea\y rectan- 

 gular blocks seven and eigiit inches 

 deep, the new practice is to spccif\- 

 cubical blocks of from three and a J 

 half to four inches, the deptii of • 

 the ordinary brick. 



The new tyjie is laid in con 

 centric interlocking rows, called 

 the oyster-shell pattern. He- 

 cause of sniallncss of the block 

 and the apparent irrigularil) 

 of joints, a gond foothold 

 for horses is obtained. 

 Another advantage is that 

 opposite wheels of 

 the vehicle are not 

 on the same course , 

 thus lessi-ning shod. 

 and nnir<- ev<-nly (lis 

 tributing the lo.id

 small block also al- 

 lows more of the 

 <l<-plh of the pave- 

 nietit to be matle up 



ofsubstantialand comnara- 

 tively cheap concrete base 

 material. 



The method of laying the 

 blocks as followed on the 

 new Brooklyn -Brighton 

 \ iaduct ill Cle\cland, Ohio, 

 is typical. They are laid 

 in a cushion of dry sand and 

 cement, mixed in the pro- 

 portions of three parts of 

 sand toone of cement on the 

 concrete base. What is laid 

 one day is thoroughly wet- 

 ted down at night so that 

 the blocks are made prac- 

 tically integral with the 

 base. The joints between 

 the blocks are then filled 

 with a mortar of one part of 

 fine sand to one part of 

 cement. In Cleveland the 

 contractor is paid §2.50 per 

 square yard for labor and 

 material for the cushion, 

 blocks and grout. The cost 

 of base will depend on its 

 depth. Small granite cube pavements have 

 been used extensively in many English 

 and European cities as well as in 

 South America for several vears.
