Surface Features For Concrete Pavements (May 1994)

Cca-road-note

With residential construction on the rise again, both homeowners and developers are seeking greater variety in pavement materials other than that provided by plain concrete or asphalt. To meet this demand, several Australian companies are producing patterned an4 col our ed concrete surface finishes to enhance paved areas in new...

ASCP Forum – Pavement Maintenance and Upgrades, Annual General Meeting, Occasional Speaker, Inaugural Industry Awards Evening

Ascp-forum-presentation, Aspcp-forum-on-demand

With an eye to future rehabilitation solutions, John Hodgkinson re-visited a CRCP overlay constructed on the Hume Highway, just north of Holbrook, in 1992. A significant milestone was reached in June 2021 as the first BCSA Rapid Set Concrete slab celebrated its 10th Birthday in Australia at Sydney International Airport. Since this...

ASCP2021 6th Concrete Pavements (e)Conference – Proceedings (with video recordings)

Conference-paper-ascp, Conference-report, Ascp-conference-presentation

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,...

Mixture Quality and Cost-Benefit Analysis of Concrete Overlay Application in Lithuania Pavements

Conf-paper-iscr

Heavy vehicles traffic flow and loads are increasing every year and influence faster degradation of asphalt pavement. A lot of money is expended on distressed pavement repair and rehabilitation, so sustainable pavement structure development is one of priority in Lithuania. Flexible (asphalt) pavement design lifetime is 20 years and often...

Concrete Highway Pavement with Thin Upper Layer Concrete and Concrete Pavement on Short Bridges

Conf-paper-iscr

For concrete pavements the new “thin upper layer concrete“ construction method, potentially in connection with the method of “thick concrete pavement“ placed on an unbound roadbase enables a 40mm thick upper layer concrete having a maximum aggregate size of only 8mm to be placed instead of a 70mm thick upper...

The Use of Continuously Reinforced Concrete Overlays in Motorway Maintenance (A Case Study)

Conf-paper-iscr

How do you undertake the repair of a jointed concrete carriageway on one of the busiest motorways in Europe, particularly when a large proportion of the joints have failed and the slabs are floating on a sea of Gault Clay. With differential settlements so severe that there was genuine concern...

Whitetoppings – Long Term Performance and Recommendations

Conf-paper-iscr

Field tests have been carried out with thin, high strength concrete overlays (whitetoppings) placed on top of the milled asphalt pavement The aim is to find methods to restore rutted asphalt pavements and iliclease their rutting resistance. The whitetopping was limited to 70 mm. Both plain and steel fibre reinforced...

Elimination of Ruts at Intersections by Means of An Inlay/Overlay Made of Steel Fibre Concrete

Conf-paper-iscr

To the North of Gent there is an important harbour and industrial zone. Because of the heavy traffic on the road connecting Gent and Zelzate (R4, section J. Kennedylaan), deep ruts have formed in the asphalt pavement, mainly at the junctions. In order to repair these ruts in a durable...

Fibrous Ferrocement – An Ideal Material for Bridge Overlays

Conf-paper-iscr

The overlays of highway bridges are usually subjected to stresses like impact stresses, longitudinal stresses, due to the application of brakes and wear and tear stresses. The moving loads on bridges have a jumping action due to uneven surface on which they move. This jumping causes shocks and vibrations of...

The Importance of Continuous Slab Support and Load Transfer at Joints in the Performance of Thin Concrete Overlays

Conf-paper-iscr

Studies on the structural performance of existing Portland cement concrete roads in South Africa (1) have shown that the traffic utilizing these roads is not the pnme initiator of structural failures. Factors such as construction, environment and slab support conditions are predominant in initiating structural failures. However, it is also...
