New Method of Paving Concrete Production

Conference-paper-ascp, Ascp-conference-presentation

Modern concrete pavements are based on sophisticated blends of cements, often containing SCM, graded nonreactive aggregates and various admixtures, all of which are aimed at producing the most durable pavement possible. Placement techniques also incorporate the use of various curing compounds, which again are aimed at producing durable concrete. However,...

Geopolymer and High Volume Fly Ash Concrete for Pavements

Conference-paper-ascp, Ascp-conference-presentation

Much interest has been shown in improving the sustainable performance of concrete. The use of cement replacement materials and geopolymer concrete offers benefits in terms of reduced carbon footprint and enhanced properties. This paper reviews the properties of geopolymer concrete and concrete with high levels of cement replacement materials relevant...

Use of recycled concrete aggregates in concrete pavements

Conference-paper-ascp, Ascp-conference-presentation

The quality of the input of fine and coarse aggregates for concrete has an influence on the quality and consistency of the new concrete, and this is particularly applicable when recycled concrete aggregates (RCA) are incorporated in the concrete. The overseas literature indicates that where substitutions do not exceed 20%,...

Use of Manufactured Sand in Concrete Pavement

Conference-paper-ascp, Ascp-conference-presentation

Recent research by the Cement Concrete & Aggregates Australia (CCAA) focused on the selection of manufactured sands for general concrete applications and for concrete road pavements. Selected manufactured sands can be used as part of the fine aggregates to deliver workable concrete for general applications and to provide good skid...

Implications of Using Manufactured Fine Aggregates in Concrete Pavements

Conference-paper-ascp, Ascp-conference-presentation

The International Center for Aggregates Research has been performing research on the use of manufactured fine aggregates (MFA) for over 15 years. The first issue was the high amounts of micro fines, i.e. minus 75 μmm, that typically exceed the amounts permitted by ASTM C33 in the production of concrete....

Fracturing Concrete Pavement Technology

Conference-paper-ascp, Ascp-conference-presentation

There are a large number of concrete pavements in Australia, with many dating back to the first half of the 20th century. These concrete pavements are still in use today, and since the time these pavements were constructed, we have seen an evolution in traffic volumes and the size of...

Recent Advances and Uses of Roller Compacted Concrete for Pavement Construction in the United States

Conference-paper-ascp, Ascp-conference-presentation

Roller Compacted Concrete (RCC) is a no slump concrete that is placed by an asphalt paver and compacted with vibratory rollers similar to asphalt pavement construction. RCC has long history of good performance as a pavement for ports, container yards, and manufacturing plants. This paper will summarize a recent survey...

Use of Fast Set Concrete For Concrete Pavement Maintenance Work

Conference-paper-ascp, Ascp-conference-presentation

The advent of the new generation of volumetric concrete mixers in conjunction with the availability of calcium sulfoaluminate cements has transformed concrete pavement maintenance practice around the world and especially in the United States, Canada and South Africa and in NSW where there is a history of 8 years’ experience...

Developments in Rapid Set Lean Concrete Subbase

Conference-paper-ascp, Ascp-conference-presentation

The technology and practice for single shift high strength concrete base replacement, mainly at night, using rapid set concrete has been established in Australia for ten years. Since 2017 this technology has now been adapted and extended to developing a rapid set lean concrete and related registered mixes. This has...
