Available in PDF, EPUB and Kindle. Book excerpt: Fifteen asphaltic concrete and seventeen portland cement concrete pavements located in Virginia were chosen for studies of aggregate wear and related wet pavement friction. Coarse aggregates from thirteen different geologic formations and quarry sources had been utilized in construction of the pavements. Field measurements of wet friction and pavement profiles and laboratory studies of aggregate petrography and surface microtexture were emphasized. The results of the research showed that aggregates can be classified into three categories based on their response to the wearing stresses of vehicle tires: (1) very homogeneous aggregates lacking significant zones and planes of weakness wear predominantly by abrasion; (2) aggregates marked by zones and planes of weakness wear predominantly by degradation or particle removal; and (3) aggregates of intermediate physical structure wear by a combination of abrasion and degradation. Polishing is most common with aggregates undergoing abrasion, the rate being dependent on the absolute hardness of the mineral constituents. Polishing removes micro-asperities and reduces the adhesion component of wet friction. The loss of macrotexture, or pavement relief, is common where degradation prevails. This loss, if excessive, retards water removal or drainage and adversely affects the hysteresis or tire deformation component of pavement friction. Optimum wet friction conditions are judged to prevail when a combination of abrasion and degradation creates an aggregate surface containing significant elements of both macro- and microtexture. It is concluded that careful petrographic study of aggregate mineralogy and texture will allow a high degree of prediction of the resulting surface configuration as aggregates wear under traffic.

This book was released on 1990 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aggregate intrinsic strength, particularly that of coarse aggregates, receives scant attention from concrete technologists and researchers as long as the w/c ratio falls within the 0.50-to-0.70 range, primarily due to the fact that the cement-aggregate bond or the hydrated cement paste fail long before aggregates do.

This book was released on 2021-09-25 with total page 1806 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume highlights the latest advances, innovations, and applications in bituminous materials and structures and asphalt pavement technology, as presented by leading international researchers and engineers at the RILEM International Symposium on Bituminous Materials (ISBM), held in Lyon, France on December 14-16, 2020. The symposium represents a joint effort of three RILEM Technical Committees from Cluster F: 264-RAP “Asphalt Pavement Recycling”, 272-PIM “Phase and Interphase Behaviour of Bituminous Materials”, and 278-CHA “Crack-Healing of Asphalt Pavement Materials”. It covers a diverse range of topics concerning bituminous materials (bitumen, mastics, mixtures) and road, railway and airport pavement structures, including: recycling, phase and interphase behaviour, cracking and healing, modification and innovative materials, durability and environmental aspects, testing and modelling, multi-scale properties, surface characteristics, structure performance, modelling and design, non-destructive testing, back-analysis, and Life Cycle Assessment. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster new multidisciplinary collaborations.

Available in PDF, EPUB and Kindle. Book excerpt: An important new state-of-the-art report prepared by RILEM Technical Committee 108 ICC. It has been written by a team of leading international experts from the UK, USA, Canada, Israel, Germany, Denmark, South Africa, Italy and France. Research studies over recent years in the field of cement science have focused on the behaviour of the interfaces between the components of cement-based materials. The techniques used in other areas of materials science are being applied to the complex materials found in cements and concretes, and this book provides a significant survey of the present state of the art.

Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this report was conducted to identify the important factors influencing the water sensitivity of asphalt paving mixtures, and to develop a test method to evaluate water sensitivity of asphalt concrete mixtures for mix design. The test method was to be performance related. A review of current procedures revealed that no single method was suitable for evaluation and related to field performance. Based on a hypothesis that air voids in the mixture may be the major source and cause of water damage, a test system was developed to evaluate the major factors that influence water sensitivity. The Environmental Conditioning System (ECS) was used to develop a test procedure that includes specimen preparation; measurement of permeability using air, water, or both; vacuum wetting; cycling at various temperatures; and continuous repeated loading while monitoring resilient modulus after each conditioning cycle.

Book excerpt: Bringing together in one volume the latest research and information, this book provides a detailed guide to the selection and use of aggregates in concrete. After an introduction defining the purpose and role of aggregates in concrete, the authors present an overview of aggregate sources and production techniques, followed by a detailed study of their physical, mechanical and chemical properties. This knowledge is then applied to the use of aggregates in both plastic and hardened concretes, and in the overall mix design. Special aggregates and their applications are discussed in detail, as are the current main specifications, standards and tests.
