Preventive Maintenance Study

This final report details the performance of 69 test sites treated with various preventive maintenance treatments. The maintenance treatments applied included crack sealing, full lane chip sealing, wheel path chip sealing, dig outs (mill and fill), blade patching, and combinations of dig outs plus crack sealing and dig outs plus full lane chip sealing. The test sites are visited yearly to assess the condition of both the maintenance treatment and the pavements in which they were installed. The cost of the treatments ranged from $1.14 to $19.57 for application on a one foot length of a 12 foot lane. All of the treatments were found to be effective in stabilizing the condition of pavements a minimum of three years and as much as five years, with some of the test sections still in good condition. The stabilization of the pavement’s condition has allowed Washington State Department of Transportation (WSDOT) to lengthen the time before rehabilitation and extend pavement life.
