Holmes, City Engineer CITY OF LUBBOCK STANDARD SPECIFICATIONS FOR THE CONSTRUCTION OF STREET CURB AND GUTTER AND STREET GUTTER DESCRIPTION Street curb and gutter find/otlatreet gutter shall consist of 30" portland cement concrete curb and gutter or separate gutter as shown on plans or as directed by the Engineer. Separate gutter will be placed only across alleys and driveways. Gutters across alleys or 'driveways shall be equal in length to the width of the alley or driveway plus the radii of the return curbs. Street Curb and Gutter will be continued around alley returns to property line as indicated on plans. FORD Forms may be of wood or metal, of a section satisfactory to the Engineer, straight, free of warp, and of a depth equal to the depth of the concrete section formed. Forms shall be constructed accurately to the line and grade as established in the field, shall be adequately braced so that they will not move during the placing of the concrete, and shall remain in place at least twelve (12) hours after placing o8n6bete. Forms shall be oiled with a light oil before each use and forms which are to be re—used shall be cleaned immediately after use and maintained in good condition. The forms shall be such that the face of the curb can be formed by use of a face form held in place by steel templates. Forms used for curb radii of the face form on curb radii be allowed. In no case will a concrete pour be started without the Engineer's approval of the forms as placed. CONCRETE MATERIALS a. Cement Portland Cement for the curbs and gutters shall conform to the Standard Specification for Portland Cement, A.S.T.M. Designation C-150, Type I. High Early Strength cement may be used upon specific approval by the Engineer and shall conform to the provisions of A.S.T.M. Designation C-150, Type III. Plant tests and certificates of conformity shall be furnished with each carload of cement. Cement from different mills, though tested and approved, shall not be mixed. Cement shall be stored and handled in a manner which will protect it from dampness and any cement which has become partially set or which contains hard lumps or cakes shall not be used. Cement salvaged from discarded or used bags shall not be used. b. Fine Aggregate Fine aggregate shall be a natural nand or mixture of such sands and shall consist of clean, hard, durable, uncoated grains, free from lumps. Deleterious substances shall not exceed the following percentages by weight: YIE M -.a- Am&- Material removed by decantation 3.0% Clay lumps . . . . . . . . . . .. . . . . . . 0.5% Other deleterious substances such as coal,shale, coated grains, and soft flaky particles . . . . 3.0% The aggregate shall be free from a harmful amount of salt or alkali, and when subjected to the color test for organic impurities shall not have a color darker than Fig. No.2 (Test in accordance with A.S.T.M.

Coarse Aasrecate Coarse aggregate shall consist of crushed stone, gravel or crushed gravel, or any combination of them, and shall be composed of hard, tough and durable particles free from adherent coating. It shall contain no salt, alkali, vegetable matter nor soft, friable, thin or elongated particles and the substances listed below shall not be present in excess of the amounts indicated: Soft fragments . . . . . . . . . . . .. . . . . .5% by weight Clay lumps . . . . . .0 0. , , . . . . , . . . .0.5% by weight Removed by decantation . . . . . . . . . . . . . *1% by weight (* 1 if consisting essentially of crusher dust). The total deleterious substances shall not exceed 5% by weight. Grading of coarse aggregate shall conform to the following requirements: Maximum size — 2 inch Retained on 1* inch screen . .0 to 5% Retained on 3/4 inch screen .. . .25 to 60% Retained on 1/4 inch screen .95 to 100% d. Water Water for this project will be furnished from a metered source of City Water. e. Expansion Joint Material Bituminous premolded expansion joint material shall conform to Item No. 402.2 (b) of the Texas State Highway Department Specifications adopted by the State Highway Department of Texas, January 13, 1938. O(02553Ai PROPORTIONING The exact amounts of all materials entering into the concrete 'shall be determined in the field in order to produce the desired durability, density, uniformity, workability and the specified strength. One bag of cement will be:considered as ninety-four (94) pounds and one gallon of water as eight and thirty-three one -hundredths ($.33) pounds. Water contained in aggregates shall be taken into account in determining the amount of water to add to the mixture. The percentage of fine to total aggregate shall be between 33% and 45%: , Concrete for Curb and Gutter and Gutter shall conform to the following: Max: Water Content U.S. Gals, Per Seek of Cement . 7.0 Min. Cement Content 94-1b. Sacks Per Cu. Yd. 5,0 Compressive strength, lbs, per sq. in... 2500 - at 28 days• Cement mortar used for top in g curb and gutter or gutters shall be composed of one (1) part cunt to two (2 parts of approved sand. The materials shall be measured by methods approved by the Engineer. PLACING, MAKING JOINTS AND FINISHING Before any concrete is placed, the subgrade shall have been shaped to the line, grade and cross-section desired, and if necessary hand tamped and sprinkled for proper compaction. If dry, the subgrade shall be thoroughly moistened (not made muddy. Concrete shall be deposited in place in such a manner as to require the minimum of rehandling and so as to obtain a uniformly dense section, free of honeycomb and conforming to the grade, thicknesses and shapes shown on the plans. If topping is to be used, the concrete basafcourse shall be°formed to the true section as shown on the plans for the various sections allowing for the correct mortar topping to finish to the final section. If no topping is used, the con- crete shall be formed slightly above the true section in order to allow for shrinkage from working and finishing operations. The cement mortar topping, if used, shall be applied as soon as the concrete base course has been finished or as soon as the concrete has set sufficiently to allow removal of the curb face form. The operation of placing the base course and the topping shall be carried on in such a manner so that in -no case shall a period of more than one (1) hour elapse between the placing -of the base course and the application of the topping. After placing the topping on the base course in the proper thickness, it shall be shaped with floats and trowels to the approximate section to insure a bond between the two courses. The section shall then be shaped by the use of a metal screed shaped to the true cross-section. At the option of the Contractor, this mortar topping may be omitted and a homogenous type of curb and gutter be. placed. Sufficient concrete shall be placed to allow for shrinkage and extra material for finishing, and the concrete shall be floated and troweled to the approximate section, and after the concrete receives a partial set the face forms shall be removed. The section shall then be shaped to the true cross-section by the use of a metal -screed which is shaped to the true cross-section. Curb and gutter shall be constructed with an expansion Joint at the tangent point of each return at intersections and at intervals of not more than fifty (50) feet between the intersections. Expansion joints shall be of the material hereinbefore xcified. Construction Joints formed by removable metal plates (templateaccurately shaped to the true cross- section of the curb and gutter shall be located at the mid-point of each section between expansion Joints or as directed by the Engineer. Contraction Joints shall be placed at ton-foot intervals. All Joints shall be perpen- dicular to the surface of the concrete and to the axis of the section. Curb and gutter shall be finished uniformly by floating with a wood float and by trowelling to an accurate cross-section. The final finish will be accomplished with a brush, the last stroke being one from the bask of curb to the lip of gutter. Both sides of all joints, the lip of gutter, and the back edge of the curb shall be finished with an approved edging tool before the final brushing. Curves at the top and bottom of the curb section shall be accurately shaped and finished and the finished curb and gutter shall present a uniform appearance without "wavesu in the face of the curb or "pockets" in the gutter. PROTECTING AND CURING All concrete work shall be covered with burlap or other suitable material as soon as it has set sufficiently to prevent marking and kept wet continuously for at least four (4) days. Care shall be taken to prevent mechanical injury during this period and until the work is accepted. Any work damaged prior to acceptance shall be repaired by the Contractor at his own expense and to the satisfaction of the Engineer. In lieu of the above method of curing, the curb and gutter may be cured by applying a liquid membrane coating to all exposed surfaces, provided such material and method is first approved by the Engineer. Immediately after the removal of forms, the curb and gutter shall be backfilled with top soil and a roll of excavated material placed against the inside face of the gutter. Concrete shall be protected against low temperatures of not less than 50 degrees F. for five (5) days after placement. If aggregate and water are heated, they shall not be heated above 175 degrees F. Concrete shall not be placed when the ambient temperature is less than 40 degrees F and falling or 35 degrees F and rising. It shall be the responsibility of the Contractor to anticipate as nearly as possible changes tt weather conditions which would affect the placement and protection of the concrete, and to be prepared to protect freshly placed concrete when sudden changes in the weather make such protection necessary s the city C'o .scion pasimd a Resolution an t ►th d* of raht 19�3s +isfint the paving p►olioy of' the City of Wbbooh#'foxas I regard to st mAtts dediost ed;ter the provisiorm of Ait y Vrdizeance gar 1331a and se Ld rorolution pro-Aded VAalw when the pzopert,y sagas propionate, cost of both helvur of eoUeotor ior leisver atmits bm4earing a subdivision has boon providod for in a ma6zer sativirectory to, the 'City# eueh stroots aha31 be placod cc a c truat.ton schedule to be 4stemined by the City Enginearl, ands & �: Wi�ASs said R"bluti.on of Herah �26, 1953 also ar f'iarved d modified the > City polfty of paying oovt diatribut;ion not forth In a Resolution pnvac4 an the 25tth der of Janus 19,51 co streets cm, an portions then at Itot dediaetad under the prorlsims of City Crdit aroe No. 1331s ends mahusa lAst" 10„ Cooper and other miners of arty'' abutting Gary Avenue fror: .W ritreet to 47th S east hava requested parmission to bate -street im;rovo- wants .constructed en mod. ear toad aa:Ld avenue fr= "th to 47th street borders Wye Slaton Add.itiotc ftsbar 4 the subdivider of which addition bed subject to Ordi=*e 2331 has aU%a1jr p1wed as W in escrow for o U Q-3 of the p"porty owner ce3t of PaOxg O&W svewm from "th to 47th etroe+t, and thins the property eta proportionato' esasts of both helvo s of Gory Averas from 4W Street to 47th Street bave been or uU be satiofactoarUr provided tor, and the pwvbW of said avenui .is ed*d tto pr**Ide *osa to 'true Area during ita uaatructiaazp�rio�ls wA the City tnginwr �s approved the plans a speci,ficationa for snap iziparove. _. ads# abdt MIREASS _ro of tbs prorwrtir stetting or. the Perin descrribed.
