Pavement Maintenance & Rehabilitation Strategies

Service Life (Years) Advantages Disadvantages
One to two Low‐cost and preventive maintenance. Short service life.
Very simple construction process. Temporary fix – does not solve the underlying issues.
Provides some time for proper repairs to be applied.
Service Life (Years) Advantages Disadvantages
Less than one Low‐cost preventive maintenance. Short service life.
Very simple construction process. Poor weather can quickly deteriorate the fix.
Service Life (Years) Advantages Disadvantages
Two to five Low‐cost preventive maintenance which extends pavement service life (two to five-year service life extensions are reported). Not suitable for significantly deteriorated pavements.
Simple construction process and traffic staging. Will not address pavement structural deficiencies.
Service Life (Years) Advantages Disadvantages
Two to five Low‐cost preventive maintenance that extends pavement service life. Not suitable for significantly deteriorated pavements.
May be utilized as a holding strategy. Will not address pavement structural deficiencies.
Simple construction process and traffic staging.
Service Life (Years) Advantages Disadvantages
Three to seven A low-cost rehabilitation treatment for existing surface-treated roads. Depending on the underlying asphalt, there may be reflective cracking within one to two years.
Simple construction process and traffic staging. Typically, only used on lower volume streets.
Minimal grade raise. Coarser surface texture than an asphalt surface.
Can be considered on some gravel roads. Will not address pavement structural deficiencies.
Service Life (Years) Advantages Disadvantages
Five to seven Generally, a low-cost preventive maintenance option. Relatively short service life.
Simple construction process and traffic staging. Depending on the underlying asphalt, there may be reflective cracking within one to two years.
Minimal grade raise. Not suitable for significantly deteriorated pavements.
Slightly coarser surface texture than an asphalt surface.
Service Life (Years) Advantages Disadvantages
Six to nine Simple construction process and traffic staging. Reflective cracking can occur within a few years.
Relatively low initial construction cost. Will not address thermal cracking or at-depth asphalt deterioration.
Will result in grade raise.
Service Life (Years) Advantages Disadvantages
Seven to 12 mple construction process and traffic staging. Reflective cracking may occur within a few years.
Relatively low initial construction cost (marginally higher cost than asphalt overlay). Will not address thermal cracking or distressed areas.
Service Life (Years) Advantages Disadvantages
10 to 15 Significantly reduces the potential for reflective cracking. Potential for reflective cracking in areas with thicker asphalt.
Existing asphalt is recycled into a high-quality material thereby maximizing recycling options for the future. Shorter construction window.
Recycling reduces the need for virgin materials and trucking. This reduces overall energy use and conserves aggregate resources. Large construction train complicating staging and traffic control.
Difficult to make major adjustments to crossfall and super-elevation.
High initial construction cost.
Service Life (Years) Advantages Disadvantages
12 to 15 Eliminates the potential for reflective cracking. High construction costs.
Provides good flexibility for grade adjustments in areas where crossfall or super-elevation correction is required. Wide range of existing asphalt depth means partial depth removal may be required to attain a 50:50 mix ratio of asphalt and granular material.
Recycles reclaimed asphalt pavement (RAP) into a higher strength material and reduces the requirement for trucking new materials on to site.
Service Life (Years) Advantages Disadvantages
12 to 15 Eliminates the potential for reflective cracking. High construction costs.
Easy to make minor grade and crossfall adjustments. Wide range of existing asphalt depth means partial depth removal may be required to attain a 50:50 mix ratio of asphalt and granular material.
Recycles RAP into a higher strength material and reduces the requirement for trucking new materials on to site.
Produces higher strength material.
Service Life (Years) Advantages Disadvantages
15 to 20 Eliminates most existing distresses or pavement structural issues. High initial construction cost.
Easy to make minor grade and crossfall adjustments. Difficult construction process and traffic staging.
Produces a high-quality pavement with a long service life. Requires virgin materials for construction, and disposal of existing asphalt and granular materials.
Eliminates the potential for reflective cracking.
Provides good flexibility for grade adjustments in areas where crossfall and super-elevation correction is required.
Service Life (Years) Advantages Disadvantages
20 Results in the highest quality pavement with the longest service life out of all rehabilitation options. Highest initial construction cost.
Removes any and all distresses or issues that may have been present with the existing pavement. Difficult construction process and traffic staging.
Provides the best flexibility for grade adjustments in areas where crossfall/super-elevation correction is required. Requires virgin materials for construction, and disposal of existing asphalt and granular materials.
