B. 
Grubbing. All roots and stumps within the limits of the road section shall be grubbed and excavated, except that no grubbing will be required where the finished roadway surface will be five feet or more above the original ground surface and the foundation soil is satisfactory. Where trees are cleared and grubbing is not required, the trunks shall be cut off flush to the ground if possible and in no event more than six inches above the ground.
C. 
Trees. Valuable shade trees may be permitted to remain in shoulder areas, but not within three feet of any curbline, if no substantial increase in the risk of injury or damage results by reason of the tree's presence in the particular place where it stands. Any such tree shall be effectively protected and preserved so as to ensure that it will suffer no damage during construction operations. All tree branches overhanging the roadway pavement or shoulder areas shall be trimmed to a clearance of 12 feet above the finished grade of the road.
D. 
Topsoil. Topsoil shall be stripped from all surfaces of the roadway section which will be disturbed by cut or fill operations. Topsoil so stripped shall be stockpiled on the site of the work and shall be reserved for roadway landscaping.
A. 
General. The excavation, filling, compacting and disposal of all material required to construct the roadbed, subgrade, shoulders, slopes and other associated improvements shall be accomplished in accordance with all applicable requirements of the State Standard Specifications for Roadway Excavation, Formation of Embankment and Disposal of Surplus Material, except as modified herein.
B. 
Unsuitable material. All unsuitable material, including material removed during clearing and grubbing and preparation of subgrade, shall be removed from within the limits of the right-of-way and disposed of lawfully at a safe location approved by the Commission.
C. 
Surplus material. Surplus suitable material may be used to flatten fill slopes within the limits of the right-of-way and any slope easements. Surplus suitable materials that cannot be so utilized shall be disposed of lawfully in a manner approved by the Commission.
D. 
Blasting. Blasting shall be performed only by licensed competent personnel and shall be done in accordance with all applicable laws, ordinances, rules and regulations pertaining thereto.
All topsoil, soft spots, peat and other organic material shall be stripped to their full depth, and boulders and ledge rock shall be removed to a depth of at least 12 inches below finished subgrade. The subgrade shall then be backfilled with bank-run gravel. The gravel shall consist of sand, gravel and soil binder, free from thin or elongated pieces, lumps or clay, soil, loam or vegetable matter or stones larger than five inches in greatest dimension. The particles shall be well graded from coarse to fine, and not more than 10% shall pass the No. 200 sieve. All construction methods shall conform to the requirements of the State Standard Specifications for Subgrade.
A. 
General. After the subgrade has been rolled and compacted, a rolled gravel base shall be applied for the full required width of pavement plus one foot beyond each curbline. The rolled gravel base shall not be less than 12 inches thick after compaction and shall be applied in two courses, each of which shall be at least six inches thick, and each course shall have the cross-slope shown on the Standard Detail Drawings.
B. 
Materials and methods. Materials and construction methods shall conform to the requirements of the State Standard Specifications for Rolled Gravel Base.
A. 
General. After the gravel base has been rolled and compacted, the roadway shall be surfaced with bituminous concrete for the full required width of pavement plus one foot beyond each curbline and to a total compacted depth of not less than three inches. The bituminous concrete shall be applied by machine in two courses, each of which shall not be less than 1 1/2 inches thick after compaction. In general, no paving shall be permitted between October 31 and March 1, unless the Commission specifically permits an exception due to unusually mild weather conditions. No paving shall be permitted on any day where the temperature is less than 40° F. Pavement shall be placed so that each course shall have the cross-slope shown on the Standard Detail Drawings.
B. 
Lanes. Where curbing is not necessary, pavement width shall be full required width only, to a compacted depth of no less than 2 1/2 inches, machine applied in two courses, each of which shall not be less than 1 1/4 inches after compaction.
C. 
Materials and methods. All materials and construction methods shall conform to the requirements of the State Standard Specifications for Two-Course Bituminous Pavement, except as modified herein.
