Cofferdams Or Cribs Which Are Tilted Or Moved Laterally During The Process Of Sinking Shall Be Righted Or Enlarged So As To Provide The Necessary Clearance. When Conditions Are Encountered Which, As Determined By The Engineer, Render It Impracticable To Dewater The Foundation Before Placing The Footing, The Engineer May Require The Construction Of A Concrete Foundation Seal Of Such Dimensions As He May Consider Necessary, And Of Such Thickness As To Resist Any Possible Uplift. The Concrete For Such Seal Shall Be Placed As Shown On The Plans Or Directed By The Engineer. The Foundation Shall Then Be Dewatered And The Footing Placed. When Weighted Cribs Are Employed And The Mass Is Utilized To Overcome Partially The Hydrostatic Pressure Acting Against The Bottom Of The Foundation Seal, Special Anchorage Such As Dowels Or Keys Shall Be Provided To Transfer The Entire Mass Of The Crib To The Foundation Seal. When A Foundation Seal Is Placed Under Water, The Cofferdams Shall Be Vented Or Ported At Low Water Level As Directed.

Rolling Shall Progress Gradually From The Sides To The Center, Parallel To The Centerline Of The Road And Shall Continue Until The Whole Surface Has Been Rolled. Any Irregularities Or Depressions That Develop Shall Be Corrected By Loosening The Material At These Places And Adding Or Removing Material Until Surface Is Smooth And Uniform. Along Curbs, Headers And Walls, And At All Places Not Accessible To The Roller, The Subbase Material Shall Be Compacted Thoroughly With Approved Tampers Or Compactors. If The Layer Of Subbase Material, Or Part Thereof, Does Not Conform To The Required Finish, The Contractor Shall, At His Own Expense, Make The Necessary Corrections. Compaction Of Each Layer Shall Continue Until A Field Density Of At Least 100 Percent Of The Maximum Dry Density Determined In Accordance With Aashto T 180, Method D Has Been Achieved. In-place Density Determination Shall Be Made In Accordance With Aashto T 191. 200.3.4 Trial Sections Before Subbase Construction Is Started, The Contractor Shall Spread And Compact Trial Sections As Directed By The Engineer. The Purpose Of The Trial Sections Is To Check The Suitability Of The Materials, The Efficiency Of The Equipment And The Construction Method Which Is Proposed To Be Used By The Contractor. Therefore, The Contractor Must Use The Same Material, Equipment And Procedures That He Proposes To Use For The Main Work. One Trial Section Of About 500 M2 Shall Be Made For Every Type Of Material And/or Construction Equipment Procedure Proposed For Use. After Final Compaction Of Each Trial Section, The Contractor Shall Carry Out Such Field Density Tests And Other Tests Required As Directed By The Engineer. If A Trial Section Shows That The Proposed Materials, Equipment Or Procedures In The Engineer's Opinion Are Not Suitable For Subbase, The Material Shall Be Removed At The Contractor's Expense, And A New Trial Section Shall Be Constructed. If The Basic Conditions Regarding The Type Of Material Or Procedure Change During The Execution Of The Work, New Trial Sections Shall Be Constructed. 200.3.5 Tolerances Aggregate Subbase Shall Be Spread With Equipment That Will Provide A Uniform Layer Which When Compacted Will Conform To The Designed Level And Transverse Slopes As Shown On The Plans. The Allowable Tolerances Shall Be As Specified Hereunder: Permitted Variation From Design ± 20 Mm Thickness Of Layer Permitted Variation From Design + 10 Mm Level Of Surface - 20 Mm Permitted Surface Irregularity 20mm Measured By 3-m Straight-edge Permitted Variation From Design Crossfall Or Camber ± 0.30 % Permitted Variation From Design Longitudinal Grade Over ± 0.10 % 25 M In Length 200.4 Method Of Measurement Aggregate Subbase Course Will Be Measured By The Cubic Meter (m³). The Quantity To Be Paid For Shall Be The Design Volume Compacted In-place As Shown On The Plans And Accepted In The Completed Course. No Allowance Will Be Given For Materials Placed Outside The Design Limits Shown On The Cross-sections. Trial Sections Shall Not Be Measured Separately But Shall Be Included In The Quantity Of Subbase Herein Measured. Section Vii.
