EMBANKMENT Sample Clauses

EMBANKMENT. Purchaser shall slope landing embankments to the original construction specifications. SECTION 10 MATERIALS 10‐17 CORRUGATED PLASTIC CULVERT Polyethylene culverts must meet AASHTO M‐294 specifications, or ASTM F‐2648 specifications for recycled polyethylene. Culverts must be Type S – double walled with a corrugated exterior and smooth interior.
EMBANKMENT. Purchaser shall slope landing embankments to the original construction specifications. SECTION 10 MATERIALS 10‐15 CORRUGATED STEEL CULVERT Metallic coated steel culverts must meet AASHTO M‐36 (ASTM A‐760) specifications. Culverts must be galvanized (zinc coated meeting AASHTO M‐218).
EMBANKMENT. The embankment consists of a series of compacted layers or lifts of suitable material placed on top of each other until the level of the subgrade surface is reached. The subgrade surface is the top of the embankment and the surface upon which the subbase is placed. Any suitable material (see §203-1.01.H) may be used to construct an embankment, although the Contractor may have to manipulate this material to make it stable. The maximum dimension of any particle of the material may not be greater than ⅔ the loose lift thickness. Any particles that are larger than ⅔ the loose lift thickness must be removed and disposed of, or may be put in the embankment side slope (see §203-1.01.F). The components of embankment construction are: Lift ThicknessMaterialDegree of Compaction The thickness of the lift is limited by the type and size of compaction equipment the contractor chooses to use. The Standard Specifications indicate the maximum loose lift thickness and mechanical requirement for various types of compaction equipment such as pneumatic-tired rollers, vibratory drum compactors, segmented pad rollers, and smooth steel wheel rollers (see§203-3.03.C). The compactors must have attached to them an identification plate which includes the manufacturer’s name and the model number of the equipment. Manufacturer’s brochures should provide the necessary data to determine the qualifications of the compactor. 3.1 Pneumatic Tired RollerThe pneumatic tired roller is classified according to tire size, tire pressure and wheel loads. Charts (Figures 203-1 & 203-2) in the Standard Specifications relate these classes to maximum loose lift thickness. The roller must make at least 6 passes at defined speeds. Figure 4 Pneumatic Tired Roller3.2 Vibratory Drum CompactorThe classification of a vibratory drum compactor is more complex, requiring computations based upon unsprung drum weight, drum width, dynamic force, operating frequency and rating frequency. This data must be supplied by the manufacturer. Fortunately, most of the vibratory rollers have been pre-qualified. The Geotechnical Engineering Bureau’s website includes listing of rollers, by manufacturer and model, and the information needed to determine the maximum loose lift thickness, speed, number of passes and vibration frequency (http://axim22.nysdot.private:7779/pls/portal/docs/PAGE/WCC_PG/TSD/TSD_BUREAUS_ TAB/TSD_GEOTECHNICAL_ENGINEERING_BUREAU_STAB/COMPACTDATA.PDF) This listing is updated periodically.

EMBANKMENT. Suggesting embankment in suitable reaches of the main river and the tributaries with proper justification as to its effectiveness with respect to existing flood problem alongwith a time frame for its execution. Designing them to cater to the flood discharge of 25, 50 or 100 years return period as per existing guidelines according to the importance of the area to be protected, Statement of the expected rise in water level, bed level, and flood slope in post embankment condition. Estimation of extent of area likely to be benefited by proposed embankments. Examining the existing embankments and suggesting their raising and strengthening.
