The proposed improvements include overlay. or reconstruction of the <br /> exaistirlg pavement and widening with curbs,. gutters and piped stornr drainage. Traffic will need to be <br /> maintained daring the roadway construction work, so the pavement design needs to accommodate <br /> staged construction with traffic operation on the base lids. Federal funding has been authorized for the, <br /> project. The proposed extension of Chad Drive, which will be constructed in a separate project, will <br /> connect inW the north end of the improved section at a new intersection. Our proposed pavement <br /> .investigation for the Chad Drive project is covered. by a separate proposal. However, we plan to <br /> combine the field investigation work for these two projects to save mobilization cc?sts and will prorato <br /> <br /> ' the combined. costs between the two projects. Our proposed work program and fee estimate for the <br /> North Game Farm Road pavement design are described beIOw. <br /> Pavement Investigation and Design Woxlc Scope <br /> 1. Field Investigation & Testing <br /> Our project engineer will visit the site to become familiar with project conditions and to mark <br /> care/boring exploration locations for underground utility clearance. The ,pavement will be visually <br /> surveyed to map areas of distress that is indicative of sttvctural or subgrade failure. <br /> Falling Weight Defleetometer (FWD) non-dsstructlve deflection tests will ba conduc#ed at 100-foot <br /> intervals in the outer wheelpaths of both directions for sutural evaluation and overlay analysis of the <br /> existing pavement and to estimate the in situ resilient modulus of the subgrade soil. <br /> Core and shallow boring explorations (maximum 5 foot depth} will ~ at two locations to <br /> measure the pavement thiclaress, classify the materials in the pavement structure, and to lag, classify <br /> and sample the subgrade sails. The exploration holes will be patched below the bound layers with <br /> compacted native materials and the bound layers will be patched using "Instant Road Repair", an <br /> ODOT QPL approved high performance asphalt patching material, compacted by vibratory hammer. <br /> We will provide traffic control (signs and flaggers) for our testing and exploration work within the <br /> roadway. <br /> 2. Laboratory Testing <br /> Soils samples from the explorations will be tested. in our laboratory for soil classification, evaluation of <br /> compaction and determination of resilient modulus (Mr). The natural water content will be determined <br /> for all samples and the samples will be examined for visual reclassification. One bulk sample will be <br /> tested to determine optimum moisture content and maximum dry density for evaluation of soil <br /> <br />
