Literature review of lower temperature asphalt systems

Abstract

A selection of the available literature on warm mix asphalt and half-warm mix asphalt were reviewed in order to ascertain whether some or all of the currently available technologies have a potential use on the UK Highways Agency's network. The review looked at the various categories of the technology, the differences required in site practices, the performance of the resulting asphalt and the environmental and economic advantages of their use. However, because there is considerably more literature than that included in this study, the findings can only be tentative.
