Title: EXPERIENCES WITH THIN BITUMINOUS LAYERS IN AUSTRIA
Accession Number: 00676631
Record Type: Component
Availability: Find a library where document is available Abstract: Thin bituminous layers have been used successfully for road maintenance in Austria for several years. Such thin layers are constructed by laying hot-, warm-, or cold-mixed material in a thickness of approximately 20 mm on existing asphalt or concrete surfaces. One of the principal applications to date has been the filling of ruts in concrete surfaces caused by studded tires. Technical requirements for thin layers are laid down in an Austrian code of standards. Those standard specifications applicable to the binder, the aggregates, the mixture and the finished layer are discussed and notes on these layers' preparation and application are provided. Recent experiences with thin layers are reported, as is current development work on noise-reducing thin layers. Austria's primary (federal) road network, with a total length of about 12,000 km, includes approximately 5 million sq m of roadway covered by thin bituminous layers. Of these layers, about 90% are hot-mixed layers. Construction costs average about $4.50/sq m. Thin bituminous layers' average service life is an estimated 8 to 10 years.
