II Grading Foundation. Foundation for the full width of the cement sidewalk shall be brought to the proper sub-grade, three inches below the surface of the finished sidewalk, and all soft or spongy material shall be removed to a depth of at least six inches below said sub-grade and replaced with earth of a quality that will pack when moistened. This earth shall then be moistened and the whole foundation tamped or rolled until it is solid. The material to be supplied in case of a fill shall be good earth and the fill shall be built up in horizontal layers not exceeding one foot each in thickness, each layer to be well packed by rolling or tamping. The fill shall be flooded with water in order to thoroughly settle it, and the whole foundation shall be well wet down before any concrete is laid thereon. A gauge, with its ends resting upon the side strings, shall be used in the determination of sub-grade. III. Shape. Cement sidewalks shall be three inches thick. In all street intersection, where there are cement or granite curb returns, the cement sidewalk shall be laid so as to cover the entire surface included within the prolongation of the side lines of the intersecting streets and the curb returns, if not shown otherwise on the plans. ORD. 029 1 IV. Construction. Cement sidewalks shall be constructed of a cement body, which shall not be less than two and one-half inches in thickness after being thoroughly compacted, and a cement mortar finishing coat which shall be not less than one-half inch in thickness, except on the front face of the walk, where, it said coat is called for, it shall be not less than one-quarter(1/4) inch in thickness. Cement concrete shall be composed of: One (1) part of Portland concrete; Three (3)parts sharp sand or stone screenings; Four(4)parts bleach gravel or five (5)parts of broken stone or river gravel Cement mortar finishing coat shall be composed of: One (1)part of Portland cement; One and one-half(1 '/2)parts of coarse, sharp, screened sand. All proportions shall be obtained by actual measurement in boxes and no material shall be used which has not been thus measured. All mixing shall be done in boxes or upon tight platforms, or in mixers. V Materials. The cement used shall be Portland cement, and shall conform to the following conditions, and be subject to the following tests: The tests shall be made by the methods and under the conditions prescribed by the Committee of the American Society of Civil Engineers, and shall be open to the contractors: Fineness. - Not less than ninety-two percent, by weight, of the cement must pass through a sieve of one hundred meshes to the inch, and not less than seventy-five percent, by weight, through a sieve of two hundred (200) meshes to the inch. Time of Setting. - The initial set of the cement shall be in not less than thirty minutes, when mixed neat with the smallest possible amount of water at the temperature at which it flows from the tap of the water system of the City of Huntington Beach, but hard set must develop in not less than one hours nor more than ten hours. Tensile Strength. - Briquettes one inch square in section shall attain at least the following tensile strength and shall show no retrogression within the ORD. 029 2 period specified. After twenty-four hours in moist air, neat, 150 pounds per square inch. After seven days (briquettes to remains in moist air one day, in water six days), neat, 450 pounds per square inch; three (3) parts sand to one (1)part cement, 150 pounds per square inch. After twenty- eight days (briquettes to remains in moist air one day, in water twenty- seven days), neat, 550 pounds of square inch; three parts sand to one part cement, 200 pounds per square inch. Soundness. - Test parts of near cement about three inches in diameter, one-half thick at the center and tapering to a thing edge shall be kept in moist air for a period of twenty-four hours. They shall then be exposed in a stream bath, above boiling water, in a loosely close vessel, for five hours. At the expiration of this time, the parts shall remains firm and hard and shall show no signs of distortion, checking, cracking or disintegrating.

The sand shall be clean, sharp, and coarse, free from loam, oil, mica, clay, vegetable matter, silt or dirt.

Should such deficiency of mortar exist, it shall be remedied by screening as noted or by carrying the proportions of fine and coarse gravel or broken stone and not by adding a greater portion of sand. Stone screenings shall be such as obtained in the crushing of hard and durable stone, and shall be that portion which has passes through a quarter-inch (1/4) mesh screen. Gravel shall be clean, hard and practically free from sand and shall have sized ranging from that of a pea minimum to three inches in the greatest dimension maximum. Broken stone shall be the"run of the crusher" from which that portion which will pass through a quarter-inch mesh screen has been removes. It shall be hard and durable in quality and shall have sizes ranging from the minimum above described up to two inches in greatest dimension. In the process of mixing the concrete, unless a machine is used, the broken stone or gravel shall be spread in a regular layer not over ten inches in depth, on the platform; upon this stone or gravel shall be uniformly spread the proper amount of sand and upon the sand shall be evenly spread the required amount of cement. The whole mass shall then be thoroughly mixed by being turned at least three times dry. Water shall then be added in a five spray and the mass turned twice wet, after which it shall be immediately ORD. 029 3 placed in position upon the foundation prepared as hereinbefore stated and tamped and rammed until it is thoroughly compacted and until free mortar appears on the surface. No concrete shall be used that shows evidence of having set or that has become unfit for good work from standing too long, or from any other cause, and no remixing of concrete till be allowed. The finishing coat shall be thoroughly mixed by turning at least three times dry, it shall then be wet, turned twice, and immediately put in place upon the surface of the concrete body, and whenever the sidewalk does not abut upon a curb or another sidewalk, down the front face to a thickness of not less than one-quarter of an inch. A small amount of neat cement must be sprinkled over the concrete body before the finishing coat is put on. The surface of the finishing coast shall be well floated, smoothly traveled and finished and marked off into blocks. A sufficient quantity of coloring matter shall be mixed with the finishing coat to give it a dark slate or a red color. The Contractor shall stamp his name on all work done by him, at intervals of not more than one hundred feet on continuous walk and not less that one on each job of less than one hundred feet in length. The letter shall not be smaller than three-quarter of an inch in height and of proportional width. They must be sunken and of a depth of not less than one-quarter of an inch. Cement sidewalks must be protected from the sun and wind and thoroughly watered for ten days after completion. Whenever the walk is laid upon a grade of five (5) percent or more it shall be finished with a floated surface. Strips used as forms at the side of the walk shall be of a width equal to the full depth of the walk.
