All work or improvement ordered to be made under the provisions of this article shall substantially conform to the following specifications:
“Scarifying”: The street shall be either plowed or rooted up, after which the old oil surface, if any, shall be well pulverized. The surface shall then be smoothed and rounded up with a road machine after which it shall be wet down and thoroughly rolled with a road roller, having a weight of not less than twelve tons.
“Oiling”: Upon the roadway thus prepared there shall be evenly applied asphaltic oil in the quantity and proportion of one-half gallon to the square yard of street surface. Said asphaltic oil and its method of application shall conform to Section 29 and Section 38 of Specifications No. 122, as adopted by Ordinance No. 39,414 (New Series) adopted October 4, 1919, by the City of Los Angeles. After the oil has been applied, a layer of crushed rock screenings or decomposed granite graduated in such size that ninety (90) per cent or more by weight, shall pass a screen having circular holes five-eighths of an inch in diameter, or “run of pit” sand and gravel as it occurs in the natural deposit containing all sizes not exceeding one inch in diameter shall be evenly spread to a depth of one half an inch. After the surface has been rolled, if oil appears on the surface, rock screenings, decomposed granite or sand grated or as the case may be, shall be applied in sufficient quantity to thoroughly cover all such places.
