Reading edition
Vide ‘Minutes of Proceedings of the Institution of Civil Engineers,’ vol. lviii. p. 95. (The first steam roller was made in the year 1864.)
[43] The first steam roller used in England was, I believe, in the year 1872; in Paris about 1864.
[44] This should be collected and “weathered” so as to get rid of mud and any organic matter in it.
[45] In Paris 3 to 3·75 ton miles of roller are applied to every cubic yard of metal; in America 5 ton miles are thought necessary.

[49] Vide ‘The Use of Steam Rollers,’ by A. W. Parry, Reading.
[50] Some road surveyors contend that for gravelled roads 6-ton rollers are heavy enough, for macadam roads 12-ton rollers.
[51] Traffic in making a roadway is apt to grind off the sharp edges and spoil the metal before it is set.
