of road construction materials, they lower energy consumption and greenhouse gas
emissions, and will provide higher satisfaction and enhanced driving experience to
the road users.
Life cycle cost analysis indicates that for high traffic volume urban arterial
roads, long lasting pavements are more cost effective over their service lives than
traditionally designed asphalt pavements. When user delay and vehicle mainte-
nance costs are included in the cost analysis, the advantages of long lasting pave-
ments are even greater. Further innovations in pavement design and material
selection should be encouraged to lessen the pavement impact on the environment.
Sustainability concepts need to be considered in pavement design selection.
