Seite 565 - Snap the cork from its position, and at the same instant start the stop watch. Stir the liquid in the bath during the run and carefully maintain it at the previously determined proper temperature. Stop the watch when the bottom of the meniscus of the oil reaches the mark on the neck of the receiving flask.
Seite 399 - When the asphaltic cement contains over 5 per cent of material that will separate by subsidence while in a molten condition, it must be thoroughly agitated before drawing from storage and while in use in the supply kettles, so as to insure a uniform cement. These properties shall be determined by tests made by uniform methods, descriptions of which are on file in the office of the Engineer Commissioner.
Seite 475 - ... provided, further, that all of the small spheres shall not be rejected and replaced by new ones at any one time, and that so far as possible the small spheres shall compose a graduated series in various stages of wear. At any time that any sphere is found to be broken or defective it shall at once be replaced.
Seite 462 - Refined Tar. — Tar freed from water by evaporation or distillation which is continued until the residue is of desired consistency; or a product produced by fluxing tar residuum with tar distillate.
Seite 420 - No. 1 broken stone, not to exceed three-eighth* (?») of an inch in thickness, shall be spread and broomed as directed by the engineer over the surface of the refined tar and shall be at once rolled as directed by the engineer with a roller weighing between eight (8) and fifteen (15) tons.
Seite 486 - The distillation shall be conducted at the rate of at least one drop and not more than two drops per second, and the distillate collected in weighed receivers. The condenser tube shall be warmed whenever necessary to prevent accumulation of solid distillates. Fractions shall be collected at the following points: 210, 235, 270, 315 and 355° C.
Seite 399 - ... run of the paving plant on surface mixture. Binder when laid shall be followed and covered with wearing surface as soon as is practicable in order to effect the most thorough bond between the binder and the wearing course. The binder course shall be kept as clean and as free from traffic as is possible under working conditions.
Seite 143 - In making the filtration, the utmost care should be exercised to avoid stirring up any of the precipitate, in order that the filter may not be clogged and that the first decantation may be as complete as possible. The sides of the flask should then be quickly washed down with naphtha and, when the crucible has drained, the bulk of insoluble matter is brought upon the felt.
Seite 460 - The components of the bitumen in petroleums, petroleum products, malthas, asphalt cements and solid native bitumens, which are soluble in carbon disulphide but insoluble in paraffin naphthas.
Seite 436 - Optional with Asphalt Cements "H" and "K." ( 1 ) The asphalt cement shall be homogeneous, free from water and shall not foam when heated to 177° C. (350° F.).
