Not illustrated. 1906 Excerpt: ...of stone and to fill all voids in the mixture. The bituminous cement shall, before mixing with the stone, be heated to between 200 and 250 F., the amount used in each batch shall be accurately weighed and used in such proportions as has been previously determined by laboratory examination to give the best results and to fill the voids in the mineral aggregates. The mixing shall be continued until the combination is a uniform concrete. In this condition it shall be hauled to the street and there spread in the prepared foundation to such a depth that, after thorough compression with a steam road roller, it shall have a thickness of two inches. The proportioning of the varying sizes of stone and bituminous cement shall be such that the compressed mixture shall, as closely as practicable, have the solidity and density of solid stone. SURFACE FINISH. After the rolling of the wearing surface tnere shall be spread over it a thin coating of Warren's quick-drying bituminous flush coat composition, or material of the same chemical and physical characteristics, the purpose of this coating being to thoroughly fill any unevenness or honeycomb which may appear in the surface of the mixture. There shall then be rolled into the surface a thin layer of stone chips for the purpose of presenting a gritty surface which will not be slippery, the size of the stone chips to be subject to the special direction of the Engineer. The stone chips will be of the same quality as stone specified for the wearing surface. The roller used for compacting the earth foundation or sub-grade, for compressing the pavement base and wearing surface, also for rolling the stone chips, shall be operated by steam power and give a weight pressure of not less than 650 pounds per lineal inch of roller.
