Design life

• The design life refers to the span of time between the initial opening to traffic until the
pavement requires a strengthening overlay.

• The design life should not be confused with the pavement life since the pavement life

can be extended by routine maintenance and rehabilitation.

• The typical design life is 10 years.

• The design life on JKR Design Method is suggested for 10 years.

• The design life begins from the road starts in use for traffic until the maintenance is

required.
