Scope of services <br />1. Non-destructive pavement deflection data shall be gathered from each <br />through traveled lane such that three sensor readings are recorded at each <br />test location at 50 to 200 foot intervals. Should Portland Cement Concrete be <br />encountered beneath the asphalt concrete, a limited number of joints will be <br />tested to determine if slab movement would preclude rehabilitation through <br />overlay. LaBelle -Marvin, Inc., shall provide Road Rater, operator, recorder <br />and traffic control as necessary to protect the traveling public and work force <br />during all phases of testing. <br />2. During deflection testing operations, notes of visual pavement conditions <br />and/or distress, cross streets, presence or absence of curb and gutter, and <br />other such observations shall be logged. <br />3. Field data collected shall be returned to our office for processing through <br />our computer. This processing shall produce a typed tabulation of all data <br />and field notes thereon, which locate the intersections of cross streets, <br />pertinent landmarks, field conditions, etc. The tabulation shall include the <br />reading of three Road Rater sensors, as well as the conversion of Road Rater <br />Sensor Number One to an equivalent Traveling Deflectometer unit. <br />4. An engineering review of test data to isolate or separate limits of similar <br />deflection response for statistical summary of data (providing the 80th <br />percentile deflection) shall be made. <br />5. Prior to field sampling operations, Underground Service Alert will be <br />notified, all test locations marked, and a meeting held, if requested, with <br />concerned utilities to relocate test sites as necessary. <br />6. Coring and boring of the in-situ roadway materials shall be performed at <br />approximate %z mile intervals from each through traveled lane to determine <br />pavement thicknesses and to obtain subgrade materials for further analysis. <br />La Belle -Marvin, Inc., shall provide traffic control during sampling <br />operations. <br />7. The in-place moisture content of the subgrade soil samples removed at <br />each location shall be determined. Individual or composite samples of <br />subgrade material which typify the materials encountered shall be selected <br />LaBelle 0 111:11evvyin <br />
