Book excerpt: This book considers the application of recycled materials both in pavement and geotechnical engineering. Currently, Australia has faced the fundamental concern of recycling waste plastic. On 1 January 2018, China enforced a prohibition on the importation of waste plastic. China's ban is followed by other countries like India, Indonesia, and Malaysia. The ban caused many corporations to abandon waste collection agreements, and the stockpiling of waste, as there is nowhere to safely deposit this waste. This issue seems, to a great extent, to have placed Australia's recycling industry in a crisis. As a result, local councils will have to find strategic ways of recycling accumulated waste that will become a more significant issue in the coming years. In Australia, apart from economic growth, the road pavement has weakened rapidly as the current pavement unable to withstand this urgent traffic load demand. The adding of polymers to the mixtures improves the stiffness, rutting resistance, and fatigue cracking [1]. However, the application of virgin polymer is costly. Thus, using waste polymer such as waste plastic polymer is an inexpensive substitute. The potential for recycled plastic to improve the performance properties of asphalt mixtures has been demonstrated in many countries the UK, Canada, The Netherlands, and India [2]. Similarly, another application of recycled materials can be in geotechnical infrastructure. This book considers the application of recycled materials both in pavement and geotechnical engineering.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural aggregates derived from a variety of source rocks have been used as a road base material. But the extraction of natural aggregates resources is increasingly being constrained by urbanization, increased costs and environmental concerns. Thus, increased amounts of reclaimed materials are being used to supplement natural aggregates in road construction. Recycled Asphalt Pavement (RAP) material is one of the important recycled materials used in the present geotechnical applications. Many agencies are constantly seeking to reap the benefits of utilizing RAP. Main advantages of utilizing RAP include the preservation of the existing profile, conservation of asphalt and aggregate resources, conservation of energy, and reduction in life-cycle cost. Therefore, it is no surprise that state highway agencies have been moving toward increasing the percentages of RAP in their HMA pavements. The 1993 EPA report mentioned that approximately 73 million tons of asphalt pavement material was recycled annually, which amounts to about 80% of the asphalt removed from pavements each year. Quarry by-products are another important recycled materials showing good performance in many geotechnical applications. These are generally obtained from crushed natural stone. One of the fines obtained from limestone stone quarries are becoming popular. These fines when they are stabilized with some cementing materials can be used in any geotechnical applications. About 159 million metric tons (175 million ton) produced annually is thought to be used in many geotechnical applications. In a recent survey, three states (Arizona, Illinois, and Missouri) indicated that quarry by-products have been used as an embankment material and three other states (Florida, Georgia, and Vermont) indicated some use of quarry by-products in base or subbase for the pavement applications. These are also used as mineral filler in asphalt paving. In this present research, a comprehensive experimental program was performed on two recycled materials which include RAP and Cemented Quarry Fines (CQF) which were used as a pavement base material. All the tests provided repeatable and reliable results. Unconfined Compressive Strength (UCS) tests showed a peak stress of 1200 kPa for the CQF which was 12 times more than the untreated sample. UCS for the RAP material showed a strength of 340 kPa which was expected for the RAP materials. Peak values for the resilient modulus for RAP and CQF were 330 MPa and 370 MPa respectively. These samples required more number of cycles to know the actual resilient modulus. Untreated sample showed a peak value of 220 MPa. Values for the swell tests was zero for the CQF whereas for the untreated sample was around 6%. RAP showed a less strain of 0.7% which is negligible for these materials. Consolidation Indices for these recycled materials showed values less than 0.001. Field monitoring data showed that the settlements and pressures were in permissible limits. Results from the experimental program along with field monitoring data showed that these recycled materials are very best suited as a pavement base material. Based on these results these recycled materials can be used for future research projects.

Download or read book Geotechnical Properties of Recycled Concrete Aggregate in Pavement Sub Base Applications written by A. Arulrajah and published by . This book was released on 2012 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a laboratory investigation of the geotechnical properties of recycled concrete aggregate (RCA). The properties of RCA were compared with state road authority requirements to assess its performance as a pavement sub-base material. The experimental programme included tests such as particle size distribution, modified Proctor compaction, particle density, water absorption, California bearing ratio (CBR), Los Angeles abrasion loss, pH, organic content, static triaxial, and repeated load triaxial tests. The Los Angeles abrasion loss tests indicated that the RCA is durable. CBR values were found to satisfy the local state road authority requirements for sub-base material. Repeated load triaxial tests established that the RCA would perform satisfactorily as a pavement sub-base material in the field. The results of the laboratory testing undertaken in this research indicated that RCA satisfied the criteria for use in pavement sub-base applications.

Download or read book Geotechnical Properties and Performances of Blended Aggregates with Recycled Glass in Pavement Applications written by Carol C.Y. Han and published by . This book was released on 2014 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internationally, recycled glass (RG) cullet has been widely utilised in road pavements from the basecourse to the surfacing. However, in the Auckland region of New Zealand, this trend has not been taken up mainly due to the lack of understanding on behaviour and performance of RG blended mixtures, and the incentive to recycle material. In this research, a comprehensive laboratory study was undertaken from locally sourced aggregates and RG cullet to illustrate the viability and influence on inclusion of RG into the basecourse. In the study, RG was introduced into the natural aggregates samples at different replacement rates, 5%, 15% and 30% by weight. The particle size distribution (PSD), optimum moisture content (OMC), pH value and Los Angeles (LA) abrasion index were determined for each of the mixtures. Standard California Bearing Ratio test (CBR) and modified double decker CBR test, or Todd Bearing Ratio test (TBR) were carried out on the natural aggregates and mixtures as a comparative test to determine the influence of the RG cullet. The CBR test is normally used in the field to evaluate pavement thickness and is a measure of the stiffness of the pavement. To ensure consistency in the results and reduce variability, the PSD conforming to TNZ M/4 specification for both aggregates and RG cullet were reconstituted for each of the tests. The OMC percentage, pH value and LA abrasion index increased as RG replacement increased. These patterns were in accordance with other studies conducted in the past. The CBR and TBR values reduced as more RG cullet was added into the mixtures. There is no such specification to evaluate the TBR test yet; however, based upon the current study, 30% RG blended mixtures reached TBR value of 73%, which was considered as marginal aggregates for pavement source material. The relationship between CBR value and TRB value was investigated. The TRB value was 63% of the value of CBR test on average. Since the PSD was pre-selected, the coefficient of variation for all the tests kept below 11%, which was considered very low for geotechnical material.
Download or read book Uses of Recycled Rubber Tires in Highways written by Jon A. Epps and published by Transportation Research Board. This book was released on 1994 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis on the use of recycled rubber tires in highways will be of interest to administrators and policy-makers; pavement, materials, geotechnical, environmental, and traffic operations engineers; and research engineers involved with highway design and construction issues. Information is provided on the uses of rubber tires in asphalt paving materials as well as other uses, such as on fills and embankments, for erosion control and on railroad grade crossings. Specifically, information is included which identifies the agencies using or implementing applications for recycled rubber tires and defines the design parameters, technical and construction limitations, performance, costs, benefits, environmental limitations, specifications, and availability. This synthesis of information defines the use of recycled rubber tires in highways and is based on a review of nearly 500 references and on information recorded from state highway agency responses to a 1991 survey of practice. Updates are included for as much of the state practice information possible through 1993. The use of scrap tires for highway applications is dynamic with regard to policy and technical issues. Therefore, the reader should keep in mind that the information presented reflects the best available data at a particular time. The synthesis also identifies current research in the topic area, critical research needs, and legislative issues that affect application and use of recycled rubber tires.
