In performing this research, a fair amount of time was spent in identifying and going through the literature, which was examined under the following subject headings: • • • • • • • • Introduction and development of highway warranties in the USA Examination of highway warranties in the USA Highway warranties in European countries Examples of performance-based road maintenance contracts with warranties Performance-based road maintenance contracts issued in the USA Standard forms of traditional design-bid-build contracts Highway and bridge specifications prepared by the state DOTs Examples of performance-based contracts other than road maintenance contracts issued in the USA Within this literature review, special consideration was given to the examination of highway construction warranties in the USA.

The warranty period can be re-established using a different portion of the normal deterioration curve. Alternative 2 determines the length of the warranty period by using a normal deterioration curve in which the initial overall condition rating of the asset is assumed to be at a certain level above the performance target but below 100% (depicted as "A" in Figure 4).
