Life Cycle Cost Analysis of Pavement

Life cycle costing analysis is a technique that quantifies all of the costs associated with the construction and maintenance of a pavement over a set analysis period. According to the report - Life-Cycle Cost Management of Interlocking Concrete Block Pavements - Methodology Report - from ARA/ICPI, a paver system is expected to last 30 or more years before it reaches the trigger pavement condition index where rehabilitation is required. During this time, the following level of maintenance is expected.

Pavement Cost

When compared to the equivalent life cycle costing of other traditional paving practices, the results for paver systems are often better because of the:

1. Higher performance life of pavers as compared to asphalt.
2. Lower capital cost of pavers compared to cast-in place concrete
3. Lower/easier maintenance requirements
4. Reduced vulnerability to utility cuts


An investment in roadway infrastructure does not stop after initial construction. Like any asset, it requires some investment to keep it in usable condition. For roadways, this includes ongoing surface maintenance, periodic restoration and eventual base rehabilitation.
Paver Surface Maintenance Timeline

Paver Surface Maintenance

At years 8 and 28, it is expected that approximately 2% of the pavers over the entire surface will have become cracked or chipped and will need to be replaced. In years 20 and 35, a more significant maintenance is expected to take place - this includes removal of a larger area of pavers (most likely in the wheelpaths), leveling/replacement of the bedding sand underneath, then reinstatement of a majority of the original pavers.
Paver installations have demonstrated life spans that exceed 30 years, as compared to traditional pavement which typically lasts 12-15 years
Sample Range of Result for Life Cycle Analysis
Although we cannot guarantee the life cycle costing will be less in every circumstance, we are willing to assist with the analysis to determine if pavers are ultimately more economical.
