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.
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
LONGER SERVICE LIFE, LESS MAINTENANCE, GREATER VALUE
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.
