"The civil engineering sector accounts for a significant percentage of global material and energy consumption and is a major contributor of waste material. The ability to recycle and reuse concrete and demolition waste is critical to reducing environmental impacts in meeting national, regional and global environmental targets. Handbook of recycled concrete and demolition waste summarises key recent research in achieving these goals.Part one considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants and the economics of managing construction and demolition waste. Part two reviews key steps in handling construction and demolition waste. It begins with a comparison between conventional demolition and construction techniques before going on to discuss the preparation, refinement and quality control of concrete aggregates produced from waste. It concludes by assessing the mechanical properties, strength and durability of concrete made using recycled aggregates. Part three includes examples of the use of recycled aggregates in applications such as roads, pavements, high-performance concrete and alkali-activated or geopolymer cements. Finally, the book discusses environmental and safety issues such as the removal of gypsum, asbestos and alkali-silica reaction (ASR) concrete, as well as life-cycle analysis of concrete with recycled aggregates."

"Reclaimed Asphalt Pavement (RAP) merupakan limbah perkerasan lentur yang telah rusak ataupun telah habis umur layannya. Di dalam RAP masih terdapat aspal dan agregat sehingga RAP dapat digunakan kembali sebagai campuran aspal baru. Namun, dalam pemanfaatan RAP diperlukan suatu bahan peremaja maupun bahan substitusi lainnya untuk memperbaiki dan meningkatkan kualitas RAP yang telah mengalami penurunan akibat penghamparan selama masa layannya. Penelitian ini dilakukan dengan menggunakan material RAP sebagai bahan daur ulang aspal dan bertujuan untuk menyelidiki pengaruh oli bekas sebagai bahan peremaja serta pengaruh limbah plastik LDPE sebagai material substitusi untuk meningkatkan ketahanan campuran dalam menahan deformasi. Penggunaan oli bekas 9% terhadap bitumen RAP mampu meningkatkan penetrasi bitumen sehingga memenuhi persyaratan untuk aspal penetrasi 60/70. Variasi limbah plastik LDPE yang digunakan adalah 5%, 6%, dan 8% dari berat aspal total. Pengaruh plastik dari hasil pengujian marshall menunjukkan penurunan stabilitas akibat limbah plastik yang belum meleleh pada suhu pencampuran (154°C) sehingga meningkatkan kebutuhan selimut aspal. Dari hasil pengujian marshall dan perbandingan variasi kadar plastik, dipilih kadar plastik terbaik 6% dari berat total aspal. Penelitian lebih lanjut untuk mengetahui laju deformasi dan stabilitas dinamis campuran dilakukan pengujian Wheel Tracking Machine (WTM) pada suhu 26°C, 35°C, 45°C dan 60°C. Dari hasil penelitian, penggunaan limbah plastik mempengaruhi kekakuan campuran yang ditunjukkan dengan nilai consolidated deformation (d0) yang lebih rendah. Selain itu, plastik juga mampu meningkatkan interlocking antar agregat sehingga meningkatkan stabilitas dinamis campuran dan menurunkan laju deformasi.

Reclaimed Asphalt Pavement (RAP) is pavement waste that has been damaged or has exhausted its service life. In the RAP there is still asphalt and aggregate so RAP can be reused as a new asphalt mixture, but its need a rejuvenating agent or other substiture material to improve the quality RAP. This research was conducted using RAP material as asphalt recycling and investigating the effect of used waste engine oil as RAP rejuvenator and the effect of LDPE plastic waste in resisting deformation. The use of 9% oil engine waste for RAP bitumen is able to increase penetration and reduce the softening point of bitumen RAP so that it meets the requirements for 60/70 penetration asphalt. The variations of LDPE plastic waste used are 5%, 6%, and 8% the total asphalt weight. The effect of plastics on the RAP mixture shows a decrease in stability due to the plastic waste that does not melt at the mixing temperature (154°C) and this increases the need for asphalt blankets. From the results of the Marshall test and the comparison of variations in plastic content, the best plastic content is 6% of the total asphalt weight selected. Further tests to determine the rate of deformation and dynamics stability were carried out by Wheel Tracking Machine (WTM) test at temperatures of 26°C, 35°C, 45°C, and 60°C. From the results, the plastic waste mixture has better deformation resistance because plastic affects the stiffness of the mixture seen from the consolidated deformation (d0) which is greater than the mixture without plastic at any temperature variation. In addition, plastics can increase interlocking between aggregates so increase dynamic stability and decrease rate of deformation.

In Indonesia, usually, construction waste is not put to good use. To prevent this cycle of destruction of nature, an innovation is needed. Innovations that can be a solution to the growing construction waste problems and to reduce the unwanted impacts on the environment. thus, it can be an alternative to the use of natural aggregates for road pavements that continue to thin out. This study plans the use of concrete waste as a substitute for coarse aggregates in wear-coated mixtures (AC-WC) as one of the manifestations of innovation to the solution to the problem of construction waste in Indonesia. Skid resistance testing is performed on modified wear-coated mixtures (AC-WC) as parameters of the influence and feasibility of using the mixture on the field.

This study planned a modified wear-coated mixture (AC-WC) with the composition of split stones as the coarse aggregates, screening as the intermediate aggregates, stone ash as fine aggregates and reclaimed concrete aggregates as the substitution of the coarse aggregates. The best optimum asphalt content, skid resistance value and the influence of concrete waste as a substitute for coarse aggregate will be compared with control samples, wear-coated mixtures (AC-WC) with a composition of coarse aggregate (split stone), medium aggregate (screening) and fine aggregate (stone ash).
