The traffic volume on German motorways increased steadily and this trend is expected to continue in the future. To guarantee mobility in the future and reduce the national economic consequential costs, road construction with a maximum service life and a minimum of necessary maintenance are needed. Rigid road pavements with...
Review of the Erosion Criteria for Bound Subbases in the Australian Rigid Pavement Design Procedure
The current Australian rigid road pavement design procedure considers both structural concrete slab fatigue and subbase erosion. The erosion component was introduced in the 1992 edition of the Austroads pavement design guide as nomographs and incorporated as algorithms in the 2004 edition of the guide. The erosion distress criteria were...
Enhanced performance of concrete with use of Carbon Nanotube enriched liquid additive
The Carbon nanotubes (CNTs) in a liquid additive when used in the design and construction of concrete, serve as nucleation sites during cement hydration to help create a denser, cement paste composition. The result is improved durability and strength. CNT technology remains young within Australia; various laboratory and field trials...
The First Concrete Freeway in South Africa
The first concrete freeway in South Africa was constructed between 1970 and 1971. It consisted of a dual carriageway, two-lane freeway with plain/jointed concrete pavement (PCP) for the traffic lanes and asphalt for the two shoulders. Three years after opening wider than normal hairline cracking was observed close to the...
ASCP2021 6th Concrete Pavements (e)Conference – Proceedings (with video recordings)
Outline 2020 tested our flexural capacity and at times strained our mental tensile strength to 85% yield. To maintain tradition, ASCP has worked hard to develop a unique line-up of papers and delivery format for its 6th Concrete Pavements Conference which was delivered in August 2021. Like previous biennial conferences,...
