Final Shaping, Trimming, and Finishing Art. 212.03 added quantities will be deducted from the item of borrow excavation, furnished excavation, or earth excavation. Topsoil furnish and place, and compost furnish and place shall be that material obtained from locations determined by the Contractor and will be measured in square yards (square meters). Excavation and embankment quantities for the roadway have been computed on the basis of cut and fill to the subgrade of the topsoil.
211.08 Basis of Payment. This work will be paid for at the contract unit price
per cubic yard (cubic meter) for TOPSOIL EXCAVATION AND PLACEMENT; per square yard (square meter) for TOPSOIL FURNISH AND PLACE, of the thickness specified; and per square yard (square meter) for COMPOST FURNISH AND PLACE, of the thickness specified. SECTION 212. FINAL SHAPING, TRIMMING, AND FINISHING
212.01 Description. This work shall consist of the final shaping, trimming,
and finishing of the roadway, the final finishing and cleaning up of the right-of-way, and completing the work for acceptance. This work is in addition to the requirements of Article 104.06. CONSTRUCTION REQUIREMENTS
212.02 Grading Sections. When the contract does not include a surface or
base course, the ditches shall be cleaned, all irregularities in the roadbed shall be smoothed out, depressions shall be filled, and the entire roadway shall be shaped, trimmed, and finished uniformly to the lines, grades, and cross sections shown on the plans, and the right-of-way cleaned up for final acceptance. The finished surface of the roadbed shall not vary from the lines, grades, and cross sections shown on the plans by more than 2 in. (50 mm).
212.03 Full Depth and Rigid Type Surface Sections. The roadway for
concrete pavement, full-depth hot mix asphalt, or pavement with concrete base course and any hot mix asphalt shall be shaped, trimmed, and finished as follows.
a.Sections Not Previously Graded. The ditches shall be cleaned, and the entire roadway shall be shaped, trimmed, and finished uniformly to the lines, grades, and cross sections shown on the plans, and the right-of-way cleaned up for final acceptance.
b.Sections Previously Graded. Where it is not necessary to secure material from the backslopes of cuts and ditches to complete the earthwork in the roadbed; or where no work is indicated on the plans which will interfere with such slopes; or where the Contractor’s operations do not disturb such slopes, no further work on the slopes will be required. If such slopes are disturbed by the Contractor’s operations, the Contractor shall trim and reshape them. Art. 212.04 Final Shaping, Trimming, and Finishing In reshaping existing shoulders and medians, widening existing embankments, or raising existing low shoulders and medians, the Contractor shall construct or reshape the shoulders and medians according to Section 480. Side slopes of fills shall be trimmed and shaped for a distance of 4 ft (1.2 m), measured from the edge of the shoulder toward the toe of the fill slope. The ditches shall be cleaned, and the right-of-way cleaned up for final acceptance.
212.04 Nonrigid Type Surface and Base Course Sections. The roadway
for nonrigid type surfacings, such as aggregate surface course or any hot-mix asphalt surface course not built on a portland cement concrete base course, shall be shaped, trimmed, and finished. After the surface or base course material has been placed, all additional construction operations shall be performed in such a manner that earth or other objectionable substances will not be deposited on the surface or base course material.
a.Sections Not Previously Graded. When the base course is constructed in a trench, all final shaping, trimming, and finishing of ditches, backslopes of cuts, and sideslopes of fills shall be completed to the lines, grades, and cross sections shown on the plans, and all shoulder material shall be roughed in before the base course material is placed. All final shaping, trimming, and finishing of the roadbed shall be completed to the lines, grades, and cross sections shown on the plans, before the surfacing material is placed.
b.Sections Previously Graded. The backslopes of cuts and ditches and the sideslopes of fills shall be finished according to Article 212.03(b) before the base course material is placed. When base course is constructed in a trench, all shoulder material shall be roughed in before the surface or base course material is placed. All final shaping, trimming, and finishing of the roadbed shall be completed before the surfacing material is placed.
212.05 Finishing. All unsuitable material, debris, and rubbish, resulting from
construction operations, or occurring within the right-of-way, and all stones or boulders more than 3 in. (75 mm) in largest dimension, shall be removed from the right-of-way and disposed of according to Article 202.03. The degree of finish for graded slopes outside of the roadbed shall be that which can be obtained by use of suitable mechanical equipment, with only such hand labor as special conditions may require. Where the roadway has been resurfaced and as directed by the Engineer, any high areas in the existing earth shoulders that remain after resurfacing is complete which would entrap water adjacent to the pavement edge shall be bladed off. The existing earth shoulders shall be sloped to drain, but grading which requires Exploration Trench Art. 213.04 additional material to conform to a uniform cross section will not be required. Immediately prior to final inspection, mowing of the right-of-way will be required at locations as directed by the Engineer.
212.06 Basis of Payment. Except for blading off high spots in the existing
earth shoulders where the roadway has been resurfaced and for mowing immediately prior to final inspection, this work will not be measured or paid for separately, but shall be considered as included in the contract unit price for the particular type of surface course, base course or widening included in the contract. If surface course, base course or widening items are not included in the contract, the cost of final shaping, trimming and finishing shall be considered as included in the contract unit prices for the various items of earthwork. Blading off high spots in the existing earth shoulders where the roadway has been resurfaced and mowing required immediately prior to final inspection will be paid for according to Article 109.04. SECTION 213. EXPLORATION TRENCH
213.01 Description. This work shall consist of constructing a trench for the
purpose of locating existing farm underdrains within the construction limits of the proposed improvement. CONSTRUCTION REQUIREMENTS
213.02 General. The exploration trench shall be constructed at the locations
shown on the plans or as directed by the Engineer. The trench shall be not less than 52 in. (1.3 m) in depth, measured from the existing ground elevation. The width of the trench shall be sufficient to allow proper investigation of the entire trench. When an existing farm underdrain is encountered, another trench shall be excavated on the opposite side of the proposed improvement to establish the line and grade of the existing farm underdrain. Broken tile shall be repaired immediately and no surface runoff shall be allowed to enter any tile. After the trench has been inspected by the Engineer, the excavated material shall be used to backfill the trench. Any excess material shall be disposed of according to Article 202.03, and the area shall be shaped and trimmed according to When approved by the Engineer, the Contractor may use other means of locating existing farm underdrains.
213.03 Method of Measurement. The exploration trench will be measured
for payment in feet (meters) of actual trench constructed.
213.04 Basis of Payment. This work will be paid for at the contract unit price
per foot (meter) for EXPLORATION TRENCH, of the depth specified.
