Work category 214: Sealed road pavement rehabilitation

Introduction

This work category provides for the replacement of, or restoration of strength to, sealed pavements where other forms of maintenance and renewal are no longer economic.

This definition applies to the 2012-15 NLTP.  For the 2015-18 NLTP please refer to the updated definition for work category 214.

Examples of qualifying activities

Examples of qualifying activities include, but may not be limited to:

• granular overlays
• rip and relay
• pavement stabilisation
• asphaltic overlays or grader-laid asphaltic material
• pavement replacement (including the use of recycled materials)
• structural asphaltic concrete rehabilitation.

Other potential activities that are not in the above list should be discussed with the NZ Transport Agency for eligibility.

Exclusions

This work category excludes:

• improvements – where it is prudent to carry out some improvements in conjunction with the rehabilitation, this may be programmed under Work category 231: Associated improvements
• pavement strengthening of unsealed roads – this is funded under Work category 211: Unsealed road metalling.

Funding assistance rate

The usual funding assistance rate is:

• the Approved Organisation’s base rate
• the Approved Organisation’s special purpose roads rate, and
• 100 percent for the NZTA (state highways).

Work category qualification

To qualify for inclusion in this work category, the work must be the long-term least-cost option for the Approved Organisation and the NZTA (state highways), calculated in terms of present value (PV).

Approved Organisations and the NZTA (state highways) must undertake economic efficiency evaluation of individual projects and make copies of the evaluations available as requested by the NZ Transport Agency.  A simplified economic efficiency procedure is provided for pavement rehabilitation in the Economic Evaluation Manual (Jan 2016) – see SP1.
