It is considered that the boring locations will be accessible to a truck mounted drill rig, and that the boring locations will be located within existing right of way and that access to private property will not be required. 4. Drill and sample soil borings and pavement cores for the proposed pavement replacement in the existing lanes or outside shoulders. It is proposed to extend the structure borings to a depth of 6.0 feet each below the roadway grade in accordance with Section 3.5.2.4 of the INDOT Geotechnical Manual. Actual boring depths will depend on the conditions of the soil encountered. 5. A truck mounted drill rig with continuous flight, hollow-stem augers, will be utilized to advance the borings. 6. Perform standard penetration testing (SPT) and retain representative soil samples in accordance with Section 3.6.1 of the INDOT Geotechnical Manual. 7. Undisturbed (Shelby tube) soil samples will be obtained within cohesive soil layers in accordance with Section 3.6.2 of the INDOT Geotechnical Manual for use in performing shear strength testing, if encountered. 8. Record groundwater observations during the drilling process and measure the water level in the borings (if encountered) upon completion. A 24-hour water level reading will be obtained in the one (1) of the borings following completion and removal of the augers. 9. Should subsurface conditions be encountered during test drilling that indicate additional or special drilling and/or special testing or analysis are required, we will request approval prior to proceeding. 10. The boreholes will be backfilled in accordance with INDOT Geotechnical Manual. Care will be taken to confirm that the boreholes do not settle and create dangerous voids. Borings in pavement will be patched with cold mix asphalt or quick set concrete to match the surrounding pavement. 11. Consultant field crews will exercise caution to minimize ground damage and will make reasonable efforts to restore the ground to the original condition. Any ground and vegetation damage incurred while gaining access to boring locations will be documented and reported. 12. During drilling, Consultant will provide traffic control during the execution of the drilling program in accordance with the INDOT Worksite Traffic Control Manual. Lane closures will be required during execution of the field work. Therefore, traffic control will be provided using a combination of signs, cones, flaggers, arrow boards and law enforcement officers, as required. This proposal considers that there will be no time restrictions associated with the required permitting and that traffic control and drilling operations can be performed within full 8-hour work days. · Task 2 – Laboratory Testing. In the laboratory, all samples will be visually classified and tested according to the INDOT Geotechnical Manual. Laboratory testing of representative samples will be performed in accordance with ASTM/AASHTO procedures to classify existing soils according to the AASHTO Classification System and to estimate engineering properties of importance for pavement design and construction considerations. In addition, the pavement cores will be visually described and photographed. The expected tests to be performed and the estimated quantities are presented in the attached fee schedule. Samples will be retained for a period of sixty (60) days after the completion of the geotechnical report, unless otherwise directed. Pavement cores will be retained until completion and acceptance of the final pavement design report. · Task 3 – Geotechnical Report.
