further mixing may be done to obtain the required moisture content. Compaction of the mixture shall begin as soon as practical. Compaction shall be in accordance with 203 or 207.03, as applicable. Acceptance of chemically modified soils will be performed on the finished grade with a Dynamic Cone Penetrometer, DCP, in accordance with ITM 509. The chemically treated soil lift shall meet the following requirements for compaction:
modification. 90
chemically treated soil for each two-lane pavement section.
for each two-lane pavement section.
lime soils mixing. A moisture test shall be performed if soil changes. 100 During embankment construction, placing of the second 12 in. lift is allowed when the first lift meets the blow counts requirements of 203.23. A third lift will not be allowed until the first lift complies with 217.09(a). Construction traffic or equipment will be allowed after the minimum DCP blow count is obtained. Construction traffic or equipment shall be routed in one direction so that the chemically modified soil does not pump or rut. 217.10 Method of Measurement The accepted quantity for drying soils will be measured by the ton of chemical 110 modifier complete in place. Soils required to construct the fill will be measured in accordance with 203.
217.11Basis of Payment
The accepted quantity of chemically modified soils will be paid for by the ton of chemical modifier used for drying. Soils required to construct the fill will be paid for in accordance with 203.
Payment will be made under: 120 Pay Item Pay Unit Symbol Drying Soils for Embankment ................................................... TON The cost of performing the laboratory tests, providing a qualified geotechnical consultant, scarification of in-situ soil, spreading, pulverization, mixing of the 217.11 258 chemical modifier and soil, moisture compaction of the resultant mixture, shaping the grade, work required due to adjustments of modifier proportioning, correction of deficient areas, water required for the modifi cation process, and all operations needed to meet the requirements of this specificatio n shall be included in the cost of the pay 130 item of this section.
