Excerpt from On Modern Carriage-Ways: Being a Paper Read Before the Sheffield Literary and Philosophical Society, on Friday, Nov, 3rd, 1843A cheaper and more successful application, of a non absorbent cement, has been used three or four years in Nottingham. I allude to the method of coating broken stone, with gas tar, for which Mr. Thomas Smart, of that town, endeavoured to obtain a patent, but without success. The stone is broken down to two inches in diameter, heated in a furnace, then covered with tar, and afterwards spread over the road about three inches thick, upon a substratum of ashes or other dry rubbish it is then rolled with a large cylinder, after which another stratum, of similar material, broken to an inch, or an inch and a half, is laid on, when the rolling is repeated.The quantity of tar de ends upon the absorbing power of the stone, and the facilities for obtaining ashes, stone, andtar, must affect any calculation of the original cost.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
