This forum explored issues related to concrete road maintenance and rehabilitation. 

Jim Grove (Federal Highway Administration), Dr Jim Cable (Cable Concrete Consultation) and Dr Peter Taylor (National Concrete Pavement Technology Centre) present on improving concrete patching practices. Areas covered included: Strength focus - are we neglecting durability Why do we patch? How long should a patch last? Opening strength requirements Thickness...

This forum addressed both concrete road pavements & concrete industrial pavements. Presentations made addressed concrete mix designs, design & construction aspects, as well as current information about diamond grinding of concrete road pavements in Australia. Presentation by David Dash covers: equipment and components used for diamond grinding United States practices...

This article is published on the ISCP web site and can be accessed from the link below. It provides guidelines for designing and conducting diamond grinding as well as providing cost information.

Ian Hampton of VCA presents on Volumetric Concrete Mixers and Rapid Set Concrete. Two new innovative products his company is bringing to the Australian market.

This presentation was part of a Forum presentation entitled “Concrete pavement construction equipment – batch plants, slipformers, diamond grinding”. It summarises that … Grinding improves ride quality improves microtexture improves macrotexture (albeit longitudinal) reduces tyre noise Grooving has no impact on ride quality has no impact on microtexture (hence no...

Concrete, used in the production of highways and pavements, may deteriorate after many years of service, due to severe exposure conditions. Due to strategic and economic importance of such infrastructures, swift action for repair works is required. Repairs with conventional concrete may take long time for gaining adequate strength, where...

Highways superficial rehabilitation appears nowadays as one environmental friendly option to increase the service life of pavements. The remaining structural section is responsible for providing enough resistance for the ongoing traffic loads. The basic goal of this kind of treatments is to recover a certain level of comfort and security...

Calcium aluminate based mortars have been widely used for fast setting repair applications. This article will present the laboratory work that was conducted to repair an existing concrete road in Istanbul. The main damage mechanism was both abrasion and frost damage; the maximum time that the road can be closed...

Life Cycle Cost Analysis (LCCA) is an economic procedure used to compare competing pavement designs, over a defined analysis period, considering all significant costs expressed in equivalent present value dollars. Currently, most agencies apply a standard, policy set, rehabilitation schedule to all pavements based on “historical” performance. However, this can...

From both an environmental and economic point of view, the availability and performance capability of infrastructure traffic areas today and in the future is of the highest priority. This applies to both public and private roads and air traffic areas, as well as for busy parking and logistics areas and...
