204.3Construction 204.3.1 General

204.3.1.1 General Requirements

(1)If retaining a portion of the existing structure, avoid damagi ng that portion during construction

operations. Do not use any equipm ent or devices that might dama ge structures, facilities, or property to be preserved and retained. Complete operations necessary to remove or abandon an existing structure and that might endanger the new construction before c onstructing new work. 204.3.1.2 Backfilling

3.At any location, to the ext ent required to avo id interferin g with the work.

(3)If removing pavement, curb, gutter, sidewalk, c rosswalk, and similar structures and portions of the

existing structure are to remai n in the surface of the finished work, remove the stru cture to an existing joint, or saw and chip the structure to a true line with a face perpendicular to the surface of the existing structure.

(2)If stockpiling material for subs equent incorporation into the work, store material at an engineer-

approved location that will minimize the hauling required to place the material. Prepare the stockpile foundation to minimize contamination. Ensure that the stockpile foundation is free of clods, lumps, or stones larger than 2 inches in any dimension.

(3)Remove the existing asphaltic pavement or surfacing without in corporating or damaging underlying

material that will remain in place. Provide a uniform milled su rface that is reasonably plane, free of large scarification marks, and has the grade and transverse slo pe the plans show or the engineer directs.

(4)Use a self-propelled milling ma chine with depth, grade, and sl ope controls. Shroud the drum to

prevent discharging loosened material into adjacent work areas or live traffic lanes. Provide an engineer-approved dust control system.

(5)Maintain one lane of traffic during working hours. Unless usin g a continuous re moval and pick-up

operation, do not windrow or stor e material on the roadway. Cle ar the roadway of materials and equipment during non-working hours. Grade shoulders adjacent to milled areas by the end of each work day to provide positive drainage of the pavement. Do not a llow abrupt longitudinal differences of 2 inches or more between lanes during non-working hours. The en gineer may waive one or more of these requirements i f the highway is closed to traffic or if a particular operation does not endanger traffic.

Effective with the December 2018 Letting 85 2019 Standard Speci fications Section 205 Roadway and Drainage Excavation

205.1Description

(1)This section describes excavating and disposing of material ta ken from within the right-of-way for

project construction.

(2)This section does not include ma terial obtained from borrow pi ts outside the right-of-way limits,

excavation for structures, or ot her excavation that separate bid items and specific measurement and payment are specified elsewhere in the specifications and contract.

205.2Materials

205.2.1 Classification

(1)The department classifies excavation as common, rock, stone pi les and stone fences, or marsh

excavation. If the contract contai ns the Excavation Common and Excavation Rock bid items, the engineer will classify that excavation as either common or rock , based on unfrozen material, as the contractor performs the work.

(2)The department classifies EBS out side of marshes as common or rock.

205.2.2 Common Excavation

(1)Under the Excavation Common bid item, excavate materials not c lassified as rock, stone piles and

stone fences, or marsh excavati on. For contracts without the Ex cavation Rock bid item, remove boulders having volumes of one c ubic yard or more under the Exc avation Common bid item. 205.2.3 Rock Excavation

(1)Under the Excavation Rock bid item, excavate hard, solid rock in ledges, bedded deposits, and

unstratified masses, and conglom erate deposits or any other material so firmly cemented they present the characteristics of solid rock, and the engineer determines it is impracticable to excavate this material without blasting or using rippers. Rock excavationals o includes removing rock boulders having a volume of one cubic yard or more.

(2)The classification of rock exca vation does not apply to crushe d aggregate or asphaltic base or surface

courses, or to concrete ba se or surface courses. 205.2.4 Stone Piles and Stone Fences

(1)Under the Excavation Stone Piles and Stone Fences bid item, re move and dispose of stones,

boulders, and rock fragments f ound assembled on the right-of-wa y in piles so that the engineer can make collective measurements by volume of the weight. If the contract includes a bid for this bid item, the classification applies to portions of the piles or assemble d stone masses found on the right-of-way that are removed and disposed of as specified. This applies reg ardless of whether this material occurs entirely above or partially below the ground surface. Do not cl assify stones in groups or piles of less than one cubic yard in volume under stone piles and stone fences. 205.2.5 Marsh Excavation

(1)Under the Excavation Marsh bid item, perform required excavation below the original ground level of

marshes and swamps underlying proposed embankments, within the limits indicated on the plans or as the engineer determines, and necessary or desirable to ensur e a stable foundation for embankment or to accelerate the subsidence of unstable material under embankment load. If old road embankment cores are encountered in areas involving marsh excav ation, salvage the portions of old road cores as designated on the pl ans and use them in the const ruction of embankments. This bid item also includes material of whatever nature encountered below the original ground elevations in areas designated for this work, exclusive of portions of old ro ad cores designated for salvage and used in construction of embankments.

(2)On contracts containing the Ex cavation Marsh bid item, excavate any marsh areas not indicated on

the plans but encountered during construction as marsh excavati on if the engineer orders removing these areas.

205.3Construction

205.3.1 General

(1)Excavate materials as the plans show or the engineer allows fr om within the right-of-way. Use

excavated material in the work to the extent practicable. Use e xcavated material with suitable engineering properties to constr uct the roadway, roadbed, emban kments, earth subgrade and shoulders, intersections, side ditches and dikes, channels, and waterways. Dispose of surplus or unsuitable material as specified in 205.3.12.

(2)Grade entrances, approaches, ditches, and channels beyond the right-of-way.
