Stone and Bock. Stone shall be erushnd from clean, sound, hard, durable lava rocks and shall be aereened dry through a two (2) inch ring and be retained on a quarter ( ~/r) inch mesh. Screenings through a Uuarter (~/4) inch mesh, from the crushed stono above specified, may be substituted for sand if approved by the engineer and inspector. The same shall be clean, dry, well graded, and Pree from excessive duet which shall not occur as a coating on the particles of atone. River Gravel: Gravel shall be clean and hard and shall vary in size from that retained on a quarter (~/4) inch mesh to the ]a.rgest particles passing a ono and a quarter (1r/4) inch mesh. Unscreened Gravel: Unacreened grave] shall be clean and hard, and shall contain no partleles larger than nne and a quarter (1 ~/4) inches. The proportion of fine and coarse parti- cles must be determined and correct- ed to agree with the requirements hereinafter specified for Cmrcrete in Base and Proportioning Foundation: When a sub-base is required only clean, hard cinders, slag lava, gravel, crushed stone nr broken brick shall he ^sed. The material shall not be smaller than one-half (~/a) inch or exceed four (4) inches in the largest dimension. Water: Water shall be roasonably clean, practically Lree from any oil, acid, aalin es and other deteriorating substances. PAVEMENT: The pavement shall ~~ be artificial etonefiagging composed of cement concrete, constructed in al- ternate slabs in plane not over three (3) Peet in width. It shall consist of two (2) parts: First, a base course three and a half (3i/z) inches thick, second, a finishing or wearing course three-quarters (s/4) oY an inch thick. Grade: Unless otherwise espe~ial- ly provided Yor, the finished surface shall be a true plane rising from the curb grade at the curb line at the rate of nne-fourth (i/a) inch to one (1) font to the property line. Preparing Sub-Grade: The space [o he orcupied by the walk shall be properly graded to a depth of four and a quarter (4r/4) inches below top of finished walk. Any soft, loose or unsnitable material found in the sub- grade shall be removed and the apace filled with fine broken sinus, cinders. or other foundation material before mentioned, after which the whole sur- face shall be thoroughly compacted by ramming or rolling and finished to required grade and cross section. Worms: When wooden forme are used they shall be free Erom warp and not less than one a,nd a half (1r/z) inches thick, except bendy Yor curved carba. All mortar and dirt shall be removed Yrom forma before being llsed. Setting: The forms shall be well staked to the line and grades given by the engineer, sand their upper edges shall conform with finished grade of the walk which shall have sufficient rise from the curb Lo Pro- vide the proper drainage of one quar- ter (y4) inch per Coot except where such rise shall parallel the length of the walk. Cross Forms: At each slab divi- sion crone Yorma shalt be put in the full width of the walk and at right angles to the aide forms. Size of Slabs: Cross forme ahnll be spaced three (3) feet apart, and in turning corners no slab shall con- tain more than thirty-six (S6) square feet. Expansion Joint: A metal Parting strip one-halt (~) inch thick shall take the place of the cross forms a[ least once every fifty (50) lineal feet on long stretches df walk. When the walk has become sufficiently hard this parting strip shall be removed and the joint filled with suitable ma- terial prior to opening the walk to traffic. Similar joints shall be pro- vided where new walk abuts curbing m• other cement or stone walk. Forms, Wet: All forms shall be thotoughly wetted before any ma- terial ie deposited against them. Base Course: The concrete for the base course shall he composed of 1: 2 r/z: 5 mixture, consisting oP three (3) parts oP clean, crushed blue-lava rock of a size not larger than will pass through a two (2) inch ring, and uoL smaller than will be retained by a three-fourths (ry4) inch ring; two (2) parts crushed blue lava rock oY a size that will pass through athree- fourths (94) inch ring, and nut smaller than will be retained by a one-fourth (r/4) inch ring; two and a half (2'/a) parts of clean, sharp sand; and one (1) part Portland Ge- ment. Sufficient water shall be added to mane a plastic mixture which shall be immediately deposited in place in such a manner that the lamer stones shall not become sepa- rated from the Grout, and shall Le thoroughly rammed until the water flushes to the top. Proportioning: When the voids are Lo be determined the concrete shall be so proportioned that the remeut shall ovsrfill the voids in the stone by at least flue (6) per centum, and the mortar shall overfill the voids iu the stone or grout by at least ten (10) per centaur. The following method shall ba used to determine voids in sand: Pill a ves- sel with sand and let net weight of sand equal B; fill swine vessel with water and let net weight of water equal A. Formula: (A x 2.66)B 100 Yer cont. Voide A x ?,.66 The following myth nd shall be used to determine voids in crashed stole and course aggregate: Fill a vessel love] full with water and let net weight of the water c~~uaL C; remove the water, dry the vessel and fill it with aggregate and let net weight of the aggrega.t.e equal B; add water slowly until iL jueL appears ott the snrfaco and weigh; let net weight of the aggregate and water equal F_. Formula: A-B-Y00 P~:~r cent. Voide C. The vessel Lo be ^sod for above re- sults shall not be lose than one (1) cubic. foot capacity. 114 fixing: The ncU ~•:~i al used in the concrete for base ec~r',a:~ r,~ust he nrr- p OPLIJttP.d by Cxa Ct `^!`4 eArenl Hll t, and for this purpose ce~a ractors will be required to pruvid~ ', ~:~~mns^h~ee wi'~lt rertangola.r boxes Y.n vi ^~isuring nm- terlnls and water-tilt Platform for mixing. No mixing of mn!erinls on pave- ments will bo Per, ~~Ited. When the measnrieg box is re- moved the mat eri~J~ shall he tho- roughly mixed dr3' ~~ ~ uniform color until no streaks of cement are visi- ble; they shall ho formed into a. crater m• trench :.d practically all the water required eP"~~I he added at one time and the nu~ss to reed until a homogeneous mortar of even con- sistency is obtained. Water may be added during Lhe prm~.ess of mixing but the concrete shall ho turned at least once immedia n~lp :after firs addi- tion. Machine Mixing: -4achine mixing will he aecopta.ble when a concrete equivalent to quality sPerifled is ob- tained. 1'he mixing of all mortar and concrete shall be thorough and satisfactory to the engineer and in- spector. Rotemperin g: Reternporing will not be premitted. Depositing: Tho concrete shall he deposited before it shows any tend- ency to harden, but in all cases the same shall be depnsirnd within thirty (30) minutes after bring mixed, and shall be transferred to the forms in water-±,ight wheelbarrows. Tho wheelbarrows shall not be filled so full as to permit mortar to slop out, and shat] not be ran over the fresh laid concrete. Care of Base: Workmen shall not be permitted to walk on freshly ]aid concrete, and wh~uv send or dust gets on the base it shall tee carefully re- moved befaro the wearing course is aPPlied. Wearing Course: Immediately af- ter the base course has been deprsit- ed and thoroughly rammed, and be- fore it becomes set. white it is still soft and adh salve, a finishing rourec, three-fourths (a/~) inch thick, con- sisting oY mixture of one (1) part screen sand and mie (Y) part Portland cement and Pori imxed two (2) pounds of lamp black to each barrel of ce- ment, sufficiently wet for proper working, shall be d=Posllcd and brought to a tree teal even surface, thoroughly worked and sk411fully troweled to a smooth and uniform finish surface.
