Title: A contractor's experience with performance-based flexible pavement design and construction specification
Abstract: Performance based contracts are being progressively introduced by Transit New Zealand to provide contractors with an opportunity to be innovative and to take greater responsibility (and risk) for road construction projects. Transit's B/3 performance based specification for structural design and construction of flexible unbound pavements, including chip seal surfacing, was introduced as a provisional document in 2000, to foster the use of marginal and non-conforming materials that give similar performance to standard basecourse and sub-base materials. Two projects completed under TNZ B/3 during 2002 and 2003 are briefly described as case studies. This paper discusses the experiences gained thus far with the two projects, and the advantages and disadvantages of a performance based specification for structural design and construction of flexible unbound pavements. The paper provides valuable, practical information for pavement designers, construction contractors and road authority engineers (a) For the covering entry of this conference, please see ITRD abstract no.
