410.07 208 The Department will measure the cubic yards (cubic meters) o f aggregate used loose in the vehicle at the point of delivery or calculate it by converting from weight using the following conversion factors: TABLE 410.06 -1 Material Conversion Factor Gravel, bank run or crusher run 2700 lb/yd³ 1600 kg/m³ Limestone, crusher run 2500 lb/yd³ 1485 kg/m³ Gravel, Size No. 4 and 57 2500 lb/yd³ 1485 kg/m³ Limestone, Size No. 4 and 57 2400 lb/yd³ 1425 kg/m³ Crushed slag [1] less than 80 lb/ft³ (1300 kg/m³) 2000 lb/yd³ 1185 kg/m³ 80 to 90 lb/ft³ (1300 to 1450 kg/m³) 2100 lb/yd³ 1250 kg/m³ 90.1 to 100 lb/ft³ (1451 to 1600 kg/m³) 2300 lb/yd³ 1365 kg/m³ 100.1 to 125 lb/ft³ (1601 to 2000 kg/m³) 2700 lb/yd³ 1600 kg/m³ more than 125 lb/ft³ (2000 kg/m³) 3000 lb/yd³ 1780 kg/m³ Recycled Portland Cement Concrete 2250 lb/yd³ 1335 kg/m³ Recycled Asphalt Pavement 2650 lb/yd³ 1570 kg/m³ [1] Based on average dry rodded weight determined by the Laboratory. The conversion factors listed are the long gradation weights. These numbers are based on the dry rodded weights of Nos. 67, 57, or 8 gradation. The Department will determine slag weights based on weights obtained from the original source. The Department will classify salvaged or mixed materials according to the material that makes up the majority of the mixture. Ensure that the moistures of the delivered material are less than 2 percent above saturated surface dry condition; if not, the Department will base payment on the dry densities and dry weights. Furnish freight bills, and weight and volume evidence accordin g to 109.
410.07 Basis of Payment. The Department will pay for accepted quantities at
the contract prices as follows: Item Unit Description 410 Cubic Yard or Ton Traffic Compacted Surface, Type A or B (Cubic Meter or Metric Ton) 410 Cubic Yard or Ton Traffic Compacted Surface, Type C (Cubic Meter or Metric Ton) ITEM 411 STABILIZED CRUSHED A GGREGATE

411.05 Basis of Payment
411.01 Description. This work consists of placing a compacted course or
courses of crushed aggregate.
411.02 Materials. Furnish materials conforming to 703.18.
411.03 Construction Methods. Construct the subgrade according to Item 204.
Use the spreading and compaction requirements of Item 304, except as modified by the following:
A.Use a maximum compacted lift thickness of 6 inches (150 mm).
B.Perform the initial compaction of the material by using crawler type tractors, tamping rollers, trench rollers, suitable pneumatic tire equipm ent, or other suitable equipment.
C.Perform final compaction of the surface of the stabilized crushed aggregate by using approved pneumatic tire equipment. Unless otherwise specified in the Contract Documents, the Engineer will perform all compaction test s according to Supplement 1015.
411.04 Method of Measurement. The Department will measure Stabilized
Crushed Aggregate by the number of cubic yards (cubic meters) computed from the profile grade, cross -sections and typical sections, compacted in place. Whe n the plans provide for the use of material in variable width or depth of course and the quantity cannot be readily calculated from the profile grade, typical sections and cross -sections, the Department will measure the cubic yards (cubic meters) by conver ting from weight using the following conversion factors: TABLE 411.04 -1 Material Conversion Factor Crushed stone 3800 lb/yd³ 2250 kg/m³ Crushed gravel 3900 lb/yd³ 2310 kg/m³ Crushed slag [1] less than 90 lb/ft³ (1450 kg/m³) 3600 lb/yd³ 2140 kg/m³ 90 to 100 lb/ft³ (1450 to 1600 kg/m³) 4000 lb/yd³ 2375 kg/m³ more than 100 lb/ft³ (1600 kg/m³) 4500 lb/yd³ 2670 kg/m³ Granulated slag 2800 lb/yd³ 1660 kg/m³ Recycled Portland Cement Concrete 3400 lb/yd³ 2020 kg/m³ Recycled Asphalt Pavement 4000 lb/yd³ 2375 kg/m³ [1] Based on average dry rodded weight of standard size of slag aggregates on record at the Laboratory. The conversion factors listed are the long gradation weights. These numbers are based on the dry rodded weights of Nos. 67, 57, or 8 gradation. The Department will determine slag weights based on weights obtained from the original source. The Department will classify salvaged or mixed materials according to the material that makes up the majority of the mixture.
