Pavement Rehabilitation Design is Not New Pavement Design

Introduction
Since the 1980’s billions of dollars have been invested in developing methods to make pavement design and construction more sustainable through the re-use of existing resources. This includes insitu recycling and re-use of existing pavement layers for flexible and rigid pavements. This technology has evolved over the years in recognised design processes captured in, for example: TG2 [1]. Specifications have been developed by various entities such as the Roads and Maritime Services in New South Wales [2][3] and Transport and Main Roads in Queensland [4]. WIRTGEN and BOMAG have also contributed by providing sophisticated insitu recycling equipment.
