Abstract
After seeing years of roadwork construction being done the same way and getting the same result of premature failures on the highly reactive subgrades in the Ipswich Council area, this author took the opportunity to research new technologies and innovations in road pavement construction.
The main objectives of this paper were:
· Investigate different pavement types used by Ipswich City Council (ICC).
· Determine how decisions are made regarding the gravel depth or use of lean mix / no fines concretes.
· Select a number of roads which have been constructed and analyse the success or failures of these roads.
· Investigate alternate technologies, innovative solutions and methods not previously used at ICC.
· Make recommendations on the costs and benefits of using the alternates.
Apart from the usual methods investigated like lime and cement stabilisation, the author found several different methods that could have significant impact on the performance of pavements in the Ipswich area:
· Foam bitumen stabilisation.
· Geosynthetics / Geogrids.
· Mass Foam blocks.
· Crushed glass in pavements.
Building road pavements on reactive subsoils is often a costly exercise and very easy to get wrong. New technologies have the ability to offer the same longevity and offer up to 30% savings over the traditional full depth gravel pavements
