Quantifying the intangible benefits of stabilisation
The tangible and intangible benefits of incorporating chemical stabilisation as a design option for new or rehabilitated pavements can be substantial. Social benefits can be accrued through a reduction in traffic delays while environmental benefits can include reuse rather than disposal of existing material, and the quarrying\haulage of the replacement material. The 2005 Whangaparaoa Road Four Laning was used as a case study to demonstrate these benefits. It is recommended that for project evaluation the environmental and social benefits are considered in addition to the economic benefits. While many of the benefits assessed for this paper are unconfirmed and possibly subjective, the main purpose has been to identify their significant influence on the evaluation process. This paper has attempted to demonstrate that the Project Evaluation Manual provides a solid base from where these benefits can be included in contract evaluations (a) For the covering entry of this conference, please see ITRD abstract no.
