Organised by SCI’s Construction Materials Group, Cases for and against hot mix road surfacings was a half day event held on 15 October 2009 at SCI HQ, London. This event was organised in partnership with the Institute of Asphalt Technology & the Institution of Highways and Transportation.
The seminar reviewed the advantages and disadvantages of the various types of hot mix asphalt that are available. The relative importance of different properties will change with the conditions that prevail on each site, making it difficult for one material to be appropriate in every case. The talks concentrated on the most commonly-used types of thin surfacing (including stone mastic asphalt), hot rolled asphalt and coated macadam (now termed asphalt concrete), as well as covering the less frequently used materials such as mastic asphalt and porous asphalt.
