Cook County, Illinois, at the locations as hereinafter set forth. be improved by constructinbi, portland Cement concrete sidewalks. together with all necessary adjustments and appurtenant construction Sidewalks are to be installed in the street at the following described location. : Central Road In the north 8ide of Central Road from a point One thousand and forty 0.040) feet east of the east line of Arth\lr Avenue to a point two hundred fifty (Z50) feet west of the west line of Kenilworth Avenue. and In the north side of Central Road from the northeasterly curb of the pavement in Rand Road to the westerly curb of the pavement in Westgate Road; (except the intervals wher~ commerical driveways are existing). Pine Street In the east side of Pine Street from the existing sidewalk in the sO\lth half of Central Road to a point one hundred and thlrty.nine (139) feet south t thereofi and In the ea8t side of Pine Street from a point three hundred and sixty-seven (367) feet south of the south line of Central Road to the exilting sidewalk In Northwelt Highway. a diBtance of OLC, h'lndred fifty-five (155) feet; and -1 - The Portla.nd Cement concrete sidewalks shall be five (5) feet in width and five (5) inches thickn and shall be constructed at the locations shown on the drawings attached hereto. The forms for the sidewalks shall be 80 set that the slab will have a fall of one (1) inch vertical to four (4) feet horizontal from the edge nearest the property line toward the edge farthest from the property line, A .ubgrade shall be prepared by excavating or filling. as the case may be. so that the top surface of the sidewalk to be constructed at the edge nearest the property line will be at the established grade. A cushion of sand two (2) inches in thickness shall be placed under all sidewalk and firmly rolled or tamped to maximum practical compaction. Upon said sand cushion there shall be placed Portland Cement concrete of a mixture of 01"!.E:: (1) part Portland Cement. two (2) parts of fine aggregate. and three and one-half (3-1/2) parts of coarse aggregate mixed as herein- after specified for concrete for sidewalk. Said fine and coarse aggregate are to be the same as hereinafter specified, The concrete shall be placed in succes.ive batches for the entire width of the slab. struck off one-half (1/2) inch higher than the finished slab, tamped until all voids are removed and free mortar appears on the surface, thoroughly spaded along the edges, struck off to the true grad.. and floated and troweled to a true and even surface. After tamping. floating and trowelling. the depth of the mixture .hall be five (5) inches. Upon completion. walk shall be brushed to produce a roughened or non- skid surface. -3- Joint filler shall be premoulded strip. of asphaltic felt one-half (1/2) inch thick and as wide as the thickness of the concrete slab. It shall have such a consistency that it will not run in summer or chip out in winter. Forms shall be of lumber two (2) inches thick or of steel of equal strength. They shall be held rigidly in place by stakes or braces with top edges at true line and grade. Ends of adjoining forms shall be flush. A template, resting upon the side forms and having the lower edge at the exact elevation of the subgrade, shall be drawn along the forms before any concrete is laid. Any high place in the subgrade shall be removed so that the template will pass over without being raised off the side forms or being tipped at an angle to the crosswalk surface. The sand cushion shall be damp when concrete is placed upon it. The wa.1k shall be divided into separate retangular slab, by marking with edging tools at five (5) foot intervals. No concrete slab shall be longer than six (6) feet or less than four (4) feet on anyone side. The surface edges and side edges of each slab shall be rounded to a radius of about on~ -fourth (1/4) inch. Expansion joints shall extend from one-quarter (1/4) inch below the surface of the walk to the subgrade, be truly at right angles to the sidewalk surface, and be made by putting the joint filler, he reinbefore specified, in place before placing the concrete. Such expens ion joints shall be placed as follows: At or near all places where the sidewalks intersect a curb line or other sidewalk or existing concrete driveways, a one (1) inch expansion joint composed of two (2) thicknesses of one-half (1/2) inch joint filler shall be made at right angles to the centerline of the walk; and at a distance of -4- approximately each fifty(50) feet between terminals of a continuous portion of the sidewalk a one -half (1/2) inch expansion joint composed of one -half (1/2) inch joint filler shall be placed at right angles to the centerline of the walk, The cement used in the construction of the Portland Cement concrete to be used in this improvement shall be of the best quality of Portland cement resulting from the calcination to incipient fusion of an intimate mixture of properly proportioned argillaceous and calcareous materials and to which nO additions greater than three percent (3%) have been made subsequent to calcination. The resultant clinker shall be 80 ground as to produce a cement so fine that at least seventy-eight percent (78%) of the volume will pass through a sieve having forty thousand (40,000) meshes to the square inch and be so seasoned as to produce an initial set in not lee s than forty-five (45) min'.ltes, Fine aggregate shall consist of sand having clean, hard, durable, uncoated grains, free from de leterious substance s. One hundred per cent (100%) shall pass a one-fourth (1/4) inch screen and ninety-five percent (950/0) shall be retained on a 100 mesh screen. Not more than twenty percent (20%) shall pass a fifty (SO) mesh screen. It shall be well graded from coarse to fine, and shall not contain more than five percent (5%) by weight of c lay or loam, none of which shall be in lumps. When the aggregate is mixed with Portland cement in the proportions of one (1) part cem.ent to two (2) parts fine aggregate by weight, according to the standard method of makbg briquettes, the resulting mortar at the age of 7 and 28 days shall have a tensile strength at least equal to that developed in the same time Ly mortar of the proportions and consistency, made of the same cement and star,dard Ottawa sand, -J- Coarse aggregate may be broken stone or grave 1. The broken stone or gravel shall be clean, hard, d!uable rock, It shall contain no organic or other deleterious matter and shall be free from soft, thin, elongated or laminated pieces. One hundred precent (100%) of the coarse aggregate shall pass a one and one-half (1-1/2) inch screen, and at least ninety-five perceEt (95%) shall be retained on a one-fourth (1/4) inch screen, with all intermediate sizes retained. These ingredients shall be mixed in a batch mixer, and the mixing shall continue until the same are uniformly distributed and the concrete is uniform in color and homogeneous, and sufficient water shall be added so as to produce concrete which can be spread into position with a template, but the amount of water used shall not be sufficient to ca.clse a separation of the coarse aggregate from the mortar in handling the concrete; said concrete shall be of a consisten.cy such that the mortar will flush to the surface under light tamping. The mixing of said concrete shall continue in the drum of the mixer not less than one (1) mi.:1ute, and the drum shall be completely emptied before receiving material for the succeeding batch. The drum shall revolve at a rate of speed not less than twelve (12) revolutions per minute. The method of measuring the nlaterials for concrete, including water, shall be one which shall insure uniform proportions of each of the materials at all times. The existing catch basins, manh,:)les, inlets, valve vaults, and handholes within the limits of the improvements shall be adjusted to the proposed sidewalk grades. These structures shall be adjusted with Portland cement mortar and brick (Grade 8 W buildin.;, bric:<., made from clay or shale, or Grade A concrete building brick). -6- Existing concrete, grave 1, and bituminous driveways which interfere with the construction as he rein provided shall be removed as nece Baary to facilitate the construction of the new sidewalk, The driveways 80 removed shall be replaced with mate rials cquiva lent to the original materials and to the same width and thickness. Fire hydrants indicated on the plans shall be moved to a new location outside the proposed sidewalk construction as directed by the Engineer. The sidewalk improvements as herein provided shall be constructed at elevations which have been determined by a minimum slope, from the top of existing curbs or edge of existing pavement (where no such curb and gutter exists) which are adjacent to the proposed sidewalk of one-quarter (1/4) inch per foot and a maximum of aIle (1) inch per foot, or as indicated on the plans, The elevation of the proposed walk shall also be governed by the elevation of existing walks, driveways and adjacent ground. Existing culverts shall be lengthened as required by the proposed sidewalk construction, Where additional material is needed to construct the proposed sidewalks to the proper grade, such material shall be secured from approved sources. Said "borrow" material shall be incorporated into the subgrade in layers not to exceed six (t:.) inches compacted thickness. Each layer shall be thoroughly compacted. Any u.tility poles interfering with the construction of the proposed improvements are to be relocated in the parkway by the utility companies. Existing concrete curb and gutter, sidewalk, fences, and other objects conflicting with the construction of the proposed sidewalk shall be removed. - 7- When excavating for sidewalk construction, all black dirt shall be removed from the sidewalk area and stored adjacent to the construction. Upon completion of the sidewalks and removal of the forms, the contractor shall dress all adjacent areas disturbed by the construction with a minimum four (4) inch thicknes. of black dirt. Disturbt~d areas shall be hand raked suita.ble for seeding, but seeding sha.ll not be done. All materials shall be of the best quality and suitable for the purpose for which they are used. All work shall be done in a workmanlike manner under the superintendence of the Board of Local Improvements of the Village of Mount Prospect, Cook COWlty, Illinois. .8- BE IT FURTHER RESOLVED that the estimate of said proposed improvement, made by the president of the Board of Local Improvements of the village of Mount prospect, as required by law, signed by him aggregating the sum of TWENTY TWO THOUSAND EIGHT HUNDRED SIXTY ONE AND 76/100 DOLLARS, ($22,861.76), is itemized to the satisfaction of the Board of Local Improvements of the Village of Mount Prospect, and is submitted herewith, be and the said estimate is hereby approved and ordered spread of record in the proceedings of this Board.
