N The following Resolution was introduced by Trustee Hynding, who moved its adoption seconded by Trustee Deleau. SPECIFICATIONS FOR ROAD OIL. RESOLVED, by the Board of Trustees of the Town,of Red:fooa City, that the following specifI Ltions be, and the same are hereby adopted by said Board of Trustees as the standard speolfioatlois for road oil to be used in the construction or repair of oiled macadam streets in said Town of RedwQe Redwood City. (A)OIL. ----- This material must be a heavy asphaltic oil prepared from California products, and must be free from6 ad—mixtures with any residue obtained by the artificial distillation of coal, coal tar or paraffins ail, and must conform to the following requirements. (B) WATER. ---------- It shall not contain more.than one half ( ) of one per cent water by volume. (0) SEDIMENT. ----------- It shall not contain more than one half ( a ) of one per cent sediment by volume. (D) VOLATILITY. ---------------- When twenty—five grams placed in a round flat bottoi¢ed tin dish , standari for such tests, is evaporated in a Blackmar or Richardson or equivalent type of asphalt oven, maintained at a uniform temperature of 220 degrees Fahrenheit, (105) degrees Obntigrade, for one hour, it shall not lose more than seven tenths of one per cent. (E) SOLUBILITY. -------------- It must, when free from water, be soluble to at least ninety—nine and five tenths in pure carbon bisulphide or chlofoform. (F) SOLUBILITY IN GASOLINE. --------------------------- The asphalt prepared as hereinafter specified, having a penetration between sevsnty—five and eighty degrees , District of Columbia standard, shall be'soluble in California Gasoline as hereinafter specified to the extent of'at least eighty --five per cent , when one hundred and, fifty cubic centimeters of gasoline are poured on five tenths of one gram of the asphalt.in solution,of one cubic centimeter of carbon bisulphide and shaken for ten minutes. This test shall be made at about 77 degrees Fahrenheit. (G) SOLUBILITY --IN TETRA—OHORIDE. ----------------------------- .— As a test for injury in over heating in preparation the asphalt shall be soluble to not more tV n three per cent less than in the carbon bisulphide solubility test, Par.(E) (H) .GASOLINE. ------------- The Gasoline herein specified shall be between sixty (60.0) and sixty and six tenths (60.6) degrees Baume at a60 F. O Between fifty—eight (58.0) and sixty—one (61.0) per cent shall distill and pass out of condenser at two hundred and twenty—five (225.0) degrees Fahrsnhelt. Not less than three (3.0) nor more than four (4.0) par cent sha31 remain in the still at three hundred and thirty (330.0) degrees Fahrenheit. The rate of distillation shall be not less than one (1.0) nor more than two (2.0) drops per second. The.amoa4.t taken for test shall be two hundred and fifty (250:0) cubic centimeters. APPARATUS. ---------- The apparatus to be used in making the diatillaticn test of gasoline, shall consist of a glass fractional distillation flask and condenser, a nitrogen filled mercury thermometer (corrected scale), a No.1 Maker burner , two pieces of NO -20 mesh wire gauze, 20.3 O.M. in Dia. and an asbestos cylinder 36.8 O.M. High x 17.8 O.M. Dia made of asbestos 1.5 M.M. thick. The distillation flask shall conform to the following measuremeits. Cap. 1000 O.C. Dia at bawl, 12.7 O.M., Dia at neck, 3,1 O.M. , Dia of tubular, ..9 C.M.
