(A) All streets shall be filled or excavated to the grade as set forth on the approved subdivision plans and further in accordance with § 153.26, and the roadway shall be improved by surfacing as herein required.
(B) The work performed and the materials used shall meet the requirements of various and applicable sections of the State Highway Commission Standard Specification for Road and Bridge Construction and Maintenance, latest edition, herein referred to as the "Standard Specifications". Copies of the Standard Specifications shall be kept on file in the office of the City Engineer. Subsequent revisions of the Standard Specifications shall go into effect at such times as the Indiana State Highway Commission effects such revisions.
(C) The general street classifications with their respective minimum dimensions and characteristics are as follows.
(1) Primary arterial thoroughfares. Surfacing shall be portland cement concrete or an approved equal bituminous surfacing may be used wherever concrete pavement is subsequently called for in this section. All plans for street construction shall be submitted to the City Engineer for approval. Width of pavement shall be 36 feet back-to-back of curbs. Included in this class of streets are all of those having such traffic that the pavement must be designed to carry an unlimited number of 22,000 pound axle loads. Pavements of this class shall be designed individually on the basis of anticipated traffic.
(2) Parkway, secondary, arterial, and feeder streets. Surfacing shall be portland cement concrete or an approved equal bituminous surfacing may be used wherever concrete pavement is subsequently called for in this section. All plans for street construction shall be submitted to the City Engineer for approval. Width of pavement shall be 36 feet back-to-back of curbs. Included in this class of streets are those having such traffic that the pavement must be designed to carry an unlimited number of 16,000 pound axle loads. The minimum pavement shall be a seven-inch plain concrete pavement, meeting construction details set out later in this chapter.
(3) Residential streets. Surfacing shall be portland cement concrete or an approved equal bituminous surfacing may be used wherever concrete pavement is subsequently called for in this section. All plans for street construction shall be submitted to the City Engineer for approval. Width of pavement shall be 32 feet back-to-back of curbs. Included in this class of streets are all residential streets, residential cul-de-sac streets, residential marginal access streets, and alleys. The pavement for this class of street must be designed to carry an unlimited number of 12,000 pound axle loads. The minimum pavement is a six- inch plain concrete pavement, meeting the construction details set out later in this chapter. Cul-de-sacs shall be paved to within 15 feet of the property line within the turn-around.
(D) The pavements as designed and constructed, in addition to the above minimums, shall be designed in accordance with the widely accepted and used design procedure as used by the State Highway Commission which takes into account the following.
(1) Traffic, including axle weights and volume.
(2) Pavement design life.
(3) Subgrade strength and character.
(4) Concrete quality.
(5) Fatigue imparted by traffic which shall not exceed 100% during the designed life of the pavement.
(E) When the following basic design conditions are met the minimum pavement may be constructed; when not met the pavement and subgrade shall be designed and constructed to meet the basic design conditions.
(1) The traffic, in the absence of data on traffic from local studies, may be determined from the State Highway Commission loadmeter and traffic volume studies in urban sections, wherein are tabulated the number of axle loads by weight groups for each type of vehicle using the particular class of street.
(2) The pavement design life is 30 years. The subgrade strength and characteristics, when constructed to the Standard Specifications give K value of 100 and CBR value of 3, the values used in determining the minimum pavement thicknesses herein.
(3) The concrete quality, when constructed to the Standard Specifications and modification herein enumerated, will meet 650 pound modulus of rupture strength, the value used in determining the minimum pavement thickness herein.
(4) Fatigue will not exceed 100% when the design analysis above required is used.
(F) Embankments and subgrades shall be constructed in accordance with their respective sections, in the latest edition of the Indiana State Highway Commission Standard Specifications.
(G) Concrete pavement and materials shall be constructed and requirements complied with in their respective sections, in the latest edition of the Indiana State Highway Commission Standard Specifications. Concrete shall be machine finished except where hand finishing is specifically permitted by the Standard Specifications. Finishing machines or vibrating strikeboards of design other than as specified in the Standard Specifications will be permitted provided work of equal quality as set out in the Standard Specifications is obtained.
(H) The pavement in parkway, secondary, arterial, feeder, and residential streets shall be jointed with transverse contraction joints at no greater than 20 feet spacing. Contraction joints may be sawed, formed, ribbon, or premolded type extending to one-fourth the pavement depth, meeting joints in adjacent lanes and extending the full width of the street including curbs.
(1) Longitudinal joints may be keyed construction joints or deformed metal keyplate, or may be sawed, formed, or of ribbon or premolded type for one-fourth the pavement depth. A longitudinal joint shall be constructed on centerline; other longitudinal joints where required shall be placed as directed, but in no case shall longitudinal joints be more than 13 feet apart.
(2) Expansion joint material ½ inch thick extending the full depth of the pavement shall be used only where fixed objects are to be isolated from the pavement. Included are where pavements abut buildings or bridges and where castings, poles, utility boxes, and lighting and traffic standards are abutting or partially or wholly within the pavement area. All joint installations shall be placed in a manner meeting the requirements of the I.S.H.C. Standard Specifications.
(I) Prior to placing the street and all surfaces, adequate subsurface drainage for the street shall be provided by the subdivider. Subsurface drainage pipe, when required, shall be not less than four inches in diameter approved by the City Engineer. Upon the completion of the street and alley improvement, plans and profiles as built shall be filed with the Commission.
(J) Bituminous paving of an approved design may be used in lieu of portland cement concrete pavement or plain concrete pavement for any use in divisions (A) through (I) above.
