182 At locations inaccessible to the above compacting equipment, the required compaction shall be obtained with approved mechanical tamps or vibrators, in which case the depth of lifts, loose measurement, shall not exceed 4 in.
203.26 Proofrolling When proofrolling is specified, the work shall be performed with an on-highway
dump truck with a minimum tire pressure of 90 psi. 1270 Proofrolling for original ground or embankment construction shall be performed using a dump truck weighing at least 15 t. Proofrolling for subgrade preparation shall be performed using a dump truck weighing at least 33 t. All proofrolled surfaces shall be covered completely with a single pass. Operating speed of the proofrolling truck shall not exceed 2 mph. Deflections or rutting in excess of 1/2 in. shall require remediation of the surface as directed. Deflection or rutting in excess of 3 in. shall require corrective remediation measures and the Department’s Geotechnical Engineering Division will be contacted. 1280 Proofrolling shall be performed after remediation measures on embankment or subgrade prior to the placement of additiona l material. There shall be one or two complete coverages as directed. Roller marks, irregularities, or failures shall be corrected.
203.27 Method of Measurement
a.Contract Quantity The quantities of excavation for which payment will be made will be those shown in the Schedule of Pay Items for the pay items, provided the project is constructed to 1290 the lines and grades shown on the plans. Unless otherwise specified, the project limits will be considered as one balance. If earthwork balances are shown on the plans, they are for information only. When the plans have been altered or when disagreement exists as to the accuracy of the plan quantities in any balance, or the contract quantity, either party shall have the right to request and cause the quantiti es involved to be measured in accordance with measured quantities. When the quantities are measured for payment, the original plan cross-sections plotted on the plans shall be used as original field cross-sections. 1300 Additional original cross-sections may be interpolated at points where necessary to determine the quantities more accurately. If the Contractor has acceptable engineered data that indicates an excavation quantity that is in error by more than 2%, then additional measurements will be performed on the areas in question and payment will be made for actual quantities.
b.Measured Quantities When payment is specified on a volume basis, all accepted excavation and borrow will be measured in its original position by cross-sectioning the area excavated, which 203.26 183 measurements will include over-breakage or slides in common excavation and 1310 unclassified excavation, not attributable to carelessness, and authorized excavation of rock, shale, peat, or other unsuitable material. Volumes will be computed from cross- section measurements by the average end area method. Measurement for payment will not include material excavated beyond authorized cross-sections. Where material is excavat ed beyond authorized cross-sections and wasted without authority, the material so wasted will be measured and deducted from the excavation quantities. Unless otherwise authorized, the amount of waste to be deducted, when common excavation, rock excavation, unclassified excavation, borrow, or other excavation has been wasted along embankments or elsewhere without 1320 authority shall be that portion of the embankment or fill which is outside a 1/4 to 1 slope in excess of that shown on the plans, and all portions outside a line from the shoulder point to a point 4 ft, measured horizontally, outside the theoretical toe of the slope. In determining waste, no tolerance in widths of shoulders will be allowed unless additional widths are authorized in writing before shoulders are finally constructed. Measurements will be made for unsuitable materials actually excavated and removed to obtain proper compaction in cut sections and in foundations for fill sections. Where it is impracticable to measure material by the cross-section method due to the erratic location of isolated depos its, acceptable methods involving three- dimensional measurements may be used to measure the material in its original position. The cubic yards of peat excavated will be determined by cross-sections, as described above, with the final cross-sections taken after complete excavation and before placing granular backfill, if peat is removed by excavation. When removal by displacement is necessary, final cross-sections will be derived from cased test holes through the completed granular treatment in accordance with 203.17. Such test holes 1340 shall be located at intervals which clearly define the bottom of the treatment between lateral limits. Pay quantities of peat excavation will be limited to the volume of peat lying between vertical lines as shown on the plans for lateral limits. Cased test holes and exploratory drilling will be measured by the linear foot; B borrow by the cubic yard, in accordance with 211.09. However, measurement to neat lines will not apply unless specifically designated. Breaking pavement will be measured by the square yard in place before breaking. (c) Measurement on a Linear Basis 1350 Linear grading will be measured by the linear foot. Measurement will be made once along each survey centerline for all linear grading comp leted on the line. Deductions will be made for bridges. Classes of excavation, except for required borrow, involved in linear grading will not be measured. 203.27 184 (d) Measurement of Excavation Items on a Weight Basis A pay item for excavation may be specified to be measured and paid for on a weight basis. When a weight basis is specified, the material will be weighed in accordance with 109.01(b). 1360
e.Measurement of Embankments When specified, embankments constructed will be measured in accordance with the terms set forth. When embankment is specified as a separa te pay item, the volume as constructed will be measured in place in accordance with 203.27(b). However, no measurement will be made for excavation or borrow, except as noted herein. The volume shall be computed in cubic yards from the dimensions of the embankment cross-sections and to the depth below completed grade to which this method of construction applies. No shrinkage factor shall be used in computing the embankment volume. Measurements 1370 will be made for unsuitable materials actually excavated and removed to obtain proper compaction in cut sections and in foundations of fill sections in accordance with 203.27(b). B borrow from off the right-of-w ay placed within embankment areas will be measured in accordance with 211.09.
f.Measurement of Borrow Borrow will be measured by the cubic yard. Except as otherwise provided herein, borrow will be cross-sectioned in its original position before excavation is started, again after it is completed, and the volume computed by the average end area method. No material shall be excavated as borrow until unsuitable material, vegetation, and 1380 other perishable matter have been removed and cross-sections taken over the cleared area. None of this removed unacceptable mate rial shall be moved back into the pit before final sections are taken. If borrow is obtained from a source where it is impracticable to measure the material in its original position, such material will be measured after being placed in embankment with no allowance made for a compaction factor. The borrow may be measured in truck beds in accordance with 211.09 for contracts having a proposal quantity less than 500 cu yds. If such source is contemplated, approval shall be obtained in writing before this part of the work is started. For quantities less than 1390 5,000 cu yds, the material may be weighed in accordance with 109.01(b) and converted from pounds shown on the weigh tickets to cubic yards using a factor of 3,000 lb/cu yd. If borrow is specified outside the limits of B borrow and if the requirements of the work do not otherwise prohibit, material in accordance with these specifications for B borrow, may be furnished and placed at the contract unit price for borrow, in which case measurement will be in accordance with 211.09. M easurement of borrow in accordance with 211.09 will be limited to nominal quantities outside the limits of structure backfill. The quantity of borrow measured for payment will not exceed the 1400 theoretical quantity of B borrow furnished. 203.27
g.Measurement of Embankment Foundation Soils Treatment Mechanical treatment of embankment foundation soils will be measured by the square yard. Chemical treatment of embankment foundation soils will be measured in accordance with 217. (h) Measurement of Wa ter for Shale, Shale and Soft Rock Mixtures, or Soft Rock When payment for water for shale is speci fied in the contract , the water for shale 1410 used will be measured by the 1,000 gal. by means of calibrated tanks or distributors, or by means of accurate water meters. When water for shale is not specified as a pay item in the contract, the water for shale that is used will not be measured directly. Such measurement will be included in that required for other pay items.
i.Lump Sum If the pay unit for a pay item for excavation is lump sum, no measurement will be made. (j) Measurement of Exploratory Cores 1420 Exploratory cores will be measured by the linear foot of rock core.
k.Measurement of Coal Ash If coal ash is used as borrow, it will be measured in accordance with 203.27(f). If coal ash is encountered during ex cavation, it will be measured as common excavation in accordance with 203.27.

If there is no pay item for common excav ation and if such is encountered, it will be paid for at the contract unit price per cubic yard for borrow. If the contract includes a pay item fo r waterway excavation, and if class Y excavation is encountered and there is no pay item for such, the class Y excavation will be paid for at 10 times the contract unit price per cubic yard for waterway excavation, or $100.00 per cu yd, whichever is greater. 1480 If the contract does not include a pay item for waterway excavation and such is encountered, pay will be determined in accordance with 104.03. If excavation is necessary to investigate or to seal sinkholes, or to explore underground drainage, the accep ted quantity involved at each location will be paid for as follows. The first 10 cu yds or fraction thereof will be paid for at 10 times the contract unit price for the class of excavation encountered. The next 40 cu yds or fraction thereof will be paid for at seven times the contract unit price for the class of excavation involved. Additional quantities will be paid for at three times the contract 1490 unit price per cubic yard for the class of excavation involved. 203.28 187 Material overlying the peat deposits which is excavated and used in embankment will be considered as common excavation and will be paid for as such.
