PREPARATION OF BASE AND LAYING OF BITUMINOUS SURFACES AND OVERLAYS
This paper relates various experiences of the author in ten years of construction practice in the Ipswich and Gold Coast areas of South East Queensland and includes some comments on recent bitumen seal failures around the state. Problems associated with paving on clay subgrades are highlighted along with two different approaches to pavement design - cement treated pavement direct on the natural subgrade and unbound granular pavement on stabilised subgrade. The use of a strain alleviating membrane interlay (sami) to obviate reflective cracking in "thin" asphalt overlays is investigated including a review of the existing pavement condition, a look at particular construction techniques and an assessment of the performance of the pavements after two and a half years of service. Some of the designer considerations and limitations of self propelled mechanical pavers are noted together with comments on a wide range of construction techniques associated with the use of pavers on unbound granular and cement treated pavements. The benefits of sealed shoulders on highly trafficked roads are discussed. Some comments are also made on recent bitumen seal failures -the contributing factors and proposed remedial measures.
