DIVISION 300

CONTRACTOR DESIGNED MODIFIED SOIL Description: This item of work will require the Contractor to design the percent of lime in the soil to obtain the maximum compressive strength to be used in the processing of modified soil.

Minimum Testing Procedure. Take one soil sample for every 500 cubic yards of soil, one per major type of soil, or a minimum of three soil samples per project, whichever is greater. Take soil samples in locations, such as in the shoulder area of a subgrade to be stabilized, and at approximate equal intervals along the project work. Determine the percent of lime by using compressive strength tests performed on the soil lime cylinders prepared according to ASTM D 5102, Method B. Perform the compressive strength test on cylinders using a 5-day cure. Use a percentage of lime by dry weight of the soil of 0, 4, 6, and 8 for each soil sample. Make three soil cylinders for each percentage at the optimum moisture of the lime-soil mixture. Recommend the percentage of lime for the project that obtains the maximum strength in 5 days.

Submit four (4) copies of a report from the Contractor or his geotechnical consultant with all the data suitably presented to the Engineer for acceptance. The Contractor or his geotechnical consultant will make a formal recommendation to the Engineer for approval of the percentage to be used on the project. The Engineer may increase the percentage of lime chosen by the laboratory data by 1 percent to meet field variations.

Basis of Payment: The work to provide all sampling, testing, a documentation to provide the field verified percent of lime to be used in the soil modification will be paid for at the contract unit price Lump Sum for CONTRACTOR MODIFIED DESIGNED SOIL.

HOT-MIX ASPHALT SURFACE REMOVAL, VARIABLE DEPTH Description. This work shall consist of removing, by rotomilling, with a machine and automatic grade control, according to Articles 440.03 and 440.04 of the Standard Specifications, the necessary existing bituminous material from the existing surface at locations indicated in the plans. The purpose of grinding is to remove the rutting in the existing bituminous surface and re-establish the required cross slope prior to paving the surface course. The milling limits and approximate depths of cuts are shown in the plans. It shall be the responsibility of the Contractor to verify the depth of cuts prior to the milling operation.

Basis of Payment. This work will be paid for at the contract unit price per Square Yard for HOT-MIX ASPHALT SURFACE REMOVAL, VARIABLE DEPTH.

LIME MODIFIER Description. This work shall consist of providing a Lime soil modifier material determined as part of the Contractor mix design to be used in the processing of the modified soil.

Materials: The soil; modifiers materials shall be in accordance with the applicable portions of Section 1001, 1002, and 1012 of the Standard Specifications.

Lime shall be “Non-Hydrated Lime (Lime Kiln Dust)” in accordance with Section 1012.03 of the

Standard Specifications.

Basis of Payment: Supplying the material to be used in the soil modification processing will be at the contract unit price per Ton for LIME.
