CONCLUSIONS AND RECOMMENDATIONS <br /> 1. The existing pavement section appears to be adequate for the traffic that it is <br /> currently carrying. <br /> 2. Some cracking and joint deterioration has occurred due to normal wear and age of <br /> the pavement. <br /> 3. Extensive pavement damage has occurred due to loss of subgrade material, <br /> settlement of the subgrade, and frost heave. <br /> 4. Pavement damage on Chandler Drive appears to be related to an existing storm <br /> sewer. <br /> 5. Where pavement damage has occurred due to settlement or frost heave, full depth <br /> repair or full panel replacement is recommended. <br /> 6. Other less costly repair methods should be used where the cracks and spalling has <br /> not affected the structural ability or driveability of the pavement. <br /> 7. Joints that have deteriorated and small cracks that have developed should also be <br /> repaired to help prevent loss of subgrade material and future pavement damage. <br /> 8. Where significant settlement has occurred, a soils investigation is recommended to <br /> determine the condition of the subgrade. <br /> 9. The existing storm sewer in Chandler Drive should be televised to determine if <br /> there are any defects in the pipe that is allowing backfill material to enter causing <br /> street settlement. <br /> 10. If repair of each street is done under separate contracts, we recommend that <br /> Chandler Drive be repaired first due to the extensive damage to the street followed <br /> by 33rd Avenue. Damage to 37th Avenue and Stinson Blvd. is less severe and repair <br /> can be done as money is available. <br /> 11. Repair of Chandler Drive can be broken into two phases with.the first phase being <br /> the removal and replacement of the damaged, easterly half of Chandler Drive <br /> within a 1200 foot reach of pavement. The remaining repair can be done as money <br /> is available. <br /> -5- <br />
