4.4.1 Stakeholder Needs

The selection of a treatment type will depend on a number of site-specific parameters relating to the job, and also the need to balance the requirements of all relevant stakeholders. The stakeholders can be broadly divided into three categories:

  • road asset managers
  • road users
  • the community.

The needs of these groups are summarised in Table 4.1.

Table 4.1: Summary of the needs of the principal stakeholder groups in surfacing selection

Road asset managersRoad usersThe community
  • Existing shape and texture
  • Climate: temperature and rainfall
  • Treatment availability
  • Maintaining access during construction
  • Initial costs including traffic management
  • Maintenance under traffic
  • Replacement costs of markings and delineation
  • Delays to road users during construction, maintenance and rehabilitation
  • Fuel consumption:
    • rolling resistance
  • Vehicle depreciation:
    • wear and tear
    • windscreen damage
  • Minimising damage to goods
  • Reducing haulage costs
  • Treating existing pavement issues:
    • surface cracking
    • texture loss
    • aggregate polishing
    • maintain waterproofing
  • Resist traffic stresses from:

    • turning/stopping
    • stresses from vertical and horizontal geometry
  • Performance of surfacing:
    • fatigue resistance
    • resistance to flushing
    • skid resistance
  • Maximising network access
  • Minimising delays
  • Reduce frequency of intervention
