A more durable solution than standard bitumen Toyota’s Altona plant in Melbourne is a key global manufacturing centre, producing 420 vehicles every working day. It is dubbed the ‘most modern car plant in the Southern Hemisphere’. To keep an operation on this scale working smoothly, every cog must be well-oiled and every element of the plant in top condition, including the hard standing surfaces around the factory. After 10 years of service, the plant’s hard standing asphalt area had reached the end of its service life. The heavy static loads imparted by giant size storage containers had gradually taken their toll on the existing asphalt surface and resurfacing was required. A harder-wearing and more durable solution was requested by the site contractors. Shell Bitumen came up with a heavier duty asphalt binder to the standard replacement C320 bitumen surface. “To date, the pavement is performing exactly as intended – over two years after it was laid, it is still showing no signs of any deformation or failure.” Brendan Camilleri, Sales Manager for the main contractor Pioneer Road Services PTY Ltd For further information please contact your Shell Bitumen representative or visit; www.shell.com/bitumen The Shell emblem, Multiphalte and SHELL are trade marks of the Shell Group. 08/2011/ CS5 Withstanding heavy loads Shell Multiphalte 1000/320 binder was selected to help ensure the asphalt mix was capable of enduring the heavy loads exerted by the daily comings and goings of heavy plant, machinery and storage containers. Prior to resurfacing, 50mm was profiled off the existing pavement structure and an emulsion tack coat was then applied. The final product comprised a 14mm dense graded asphalt, incorporating Shell Multiphalte 1000/320 bitumen. In total 4600m 2 of Toyota’s terminal was milled out and resurfaced. The work was carried out during the winter period but despite the cool temperatures, there were no workability issues with the asphalt, and 98% compaction was achieved (compared to the target of 94%). Toyota Australia manufactured a record 148,931 vehicles and 112,415 engines at the Altona plant in 2007 Using Shell Multiphalte 1000/320 will help to improve pavement fatigue resistance properties and rutting resistance, compared with conventional bitumen. This should help to provide a longer pavement life and improved in-service performance.
