The following standards are established for all new commercial, industrial, institutional and multi-family parking areas, driveways and private streets, and for additions to or applicable reconstruction of existing commercial, industrial, institutional and multi-family residential parking areas, driveways and private streets:
(a) All front-loading dumpsters shall be placed on minimum ten (10) foot by twenty (20) foot pads and all forty-two (42) cubic yard compactors shall be placed on minimum fourteen (14) by thirty (30) foot pads; all such pads shall be constructed of nine (9) inches of reinforced class “C” concrete pavement. All dumpsters and compactors shall be enclosed in accordance with City Standards with the concrete pad extending a minimum of ten (10) feet in front of the enclosure gate.
(b) Unless the City Manager or his designee approves an equivalent alternate, all other areas shall be constructed as follows:
(1) The contractor shall be responsible for removing all soft spots, finely grading and compacting the subgrade to twelve (12) inches below the surface to 100% of the maximum dry density as determined by AASHTO T99. All compaction and subgrade shall be tested and certified by an approved testing lab and/or as directed by the City Inspector.
(2) Full depth asphalt shall be constructed as follows:
A. Lay one four (4) inch compacted course of ODOT Item 301 Bituminous Aggregate Base on the approved subgrade.
B. Lay one and one-half (1-1/2) inch compacted course of ODOT Item 446 Asphaltic Concrete Intermediate Course, Type 1, on the 301 base.
C. After completion of all construction activity, the contractor/owner shall repair all damaged areas.
D. Apply Item 407 Tack Coat at one-tenth (0.1) gallon per square yard, and lay the final one and one-half (1-1/2) inch compacted course of ODOT Item 446 Asphaltic Concrete Surface Course.
E. All compaction operations shall be performed by a ten (10) ton minimum roller.
(3) Granular base asphalt pavement shall be constructed as follows:
A. Lay one four (4) inch compacted base course of No. 2 stone or ODOT Item 304 on the approved subgrade. Key with fine stone until the voids are filled.
B. Lay a second four (4) inch compacted base course of ODOT Item 304 on the first course. Key with fine stone until the voids are filled. Have the density certified by an approved testing lab in accordance with ODOT Item 304.04, and/or as directed by the City Inspector.
C. Lay one two and one-half (2-1/2) inch compacted course of ODOT Item 446 Asphaltic Concrete Intermediate Course, Type 1, on the approved base.
D. After completion of all construction activity, the contractor/owner shall repair all damaged areas.
E. Apply Item 407 Tack Coat at one-tenth (0.1) gallon per square yard, and lay the final one and one-half (1-1/2) inch compacted course of ODOT Item 446 Asphaltic Concrete Surface Course, Type 1.
F. All compaction operations shall be performed by a ten (10) ton minimum roller.
(4) Concrete pavement.
A. Parking lot pavement for cars only shall be six (6) inches of ODOT Item 452 Plain Portland Cement Concrete Pavement on an approved subgrade. Concrete shall be class “C”.
B. Ingress and egress drives, and areas which shall support construction vehicles, truck traffic or trash collection vehicles shall be seven (7) inches of ODOT Item 452 Plain Portland Cement Concrete Pavement on an approved subgrade. Concrete shall be class “C”.
(5) Concrete Curb.
A. Concrete curbing shall meet the requirements of ODOT Item 609.
B. Extruded concrete curbing.
1. Description: When approved for use by the City Manager or his designee as an equivalent alternate, extruded concrete curbing shall consist of furnishing and constructing slip-form paved concrete curbing bonded over existing pavement, of the specified materials and types, in reasonable close conformity with the lines, grades and cross section shown on the plans or established by the City Engineer.
2. Performances: Strength shall be not less than five thousand (5,000) psi at 28 days. Fiber mesh reinforcement and 6% air entrainment shall be provided. The slump shall not exceed one and one-half (1-1/2) inch. Water reducer and/or set retarder shall be adjusted for materials, conditions, and/or weather and slump requirements, while maintaining the strength requirement of the mix.
3. Construction: A slip-form paving machine may be used. The concrete shall be of such consistency that it can be molded into the desired shape and then remain as placed without slumping of the vertical faces. Contraction joints shall be one-fourth (1/4) inch wide, placed at ten (10) foot intervals according to ODOT 609.04. Immediately after removing the form, the exposed curb shall be brushed once, in one direction, and shall immediately be sprayed with a liquid-membrane-curing compound meeting ASTM C-309, clear or pigmented. The curb is to be bonded to the existing pavement with a two-part epoxy-bonding agent.
