Portland cement has undergone much change in recent decades to cater for rapid construction cycles, longer design life and environmental pressure. Increased fineness, the advent of Portland blended cements incorporating one or more supplementary cementitious materials (SCMs), and reduced clinker content via mineral addition have been the key technological solutions...
Merits and Challenges of Increasing Limestone Addition in Cement Used in Concrete Pavement Construction
Geopolymer and High Volume Fly Ash Concrete for Pavements
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
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%,...
The Role of Quality Assurance in Delivering Long-Life Concrete Pavements
The fundamental goal of any pavement design and construction project is to provide a pavement system that will survive the predicted traffic and environment for the pavement design life. Structural design is primarily considered as the way to meet that goal. Concrete mixtures and construction practices are generally assumed to...
Use of Manufactured Sand in Concrete Pavement
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
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....
Key Components in Long Term Sustainability of Concrete Pavement Systems & Sustainability Considerations for PCC Pavement Design and Construction
This paper addresses key issues regarding important factors affecting the sustainability and long-term performance of PCC pavement structures. Key distress types and their associated features are discussed in terms of their effect on performance and sustainabilityin terms of specific pavement components. Relevantmaterialproperties are also identified and discussed as to how...
