This book was released on 2013 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to particulates common in crumb rubber-modified asphalt binders, conventional PG grading using the Dynamic Shear Rheometer (DSR) with a gap height of 1.0 mm may not be valid and in accordance with current specifications. Asphalt binder testing and mixture testing was conducted on binders with and without crumb rubber modification to determine an asphalt binder test method which best matches the mixture performance. It was determined that the Multiple Stress Creep Recovery (MSCR) test, conducted with a gap height of 2.0 mm and at in-service temperatures, best correlated with Flow Number testing in the Asphalt Mixture Performance Tester (AMPT). This relationship was found to be better than that of the current DSR test procedure for high temperature PG grading.

Book Synopsis Long and Deep Tunnels by : Vittorio Guglielmetti
Download or read book Long and Deep Tunnels written by Vittorio Guglielmetti and published by CRC Press. This book was released on 2016-04-15 with total page 1336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and construction of “long and deep” tunnels, i.e. tunnels under mountains, characterised by either considerable length and/or overburden, represent a considerable challenge. The scope of this book is not to instruct how to design and construct such tunnels but to share a method to identify the potential hazards related to the process of designing and constructing long and deep tunnels, to produce a relevant comprehensive analysis and listing, to quantify the probability and consequences, and to design proper mitigation measures and countermeasures. The design, developed using probabilistic methods, is verified during execution by means of the so called Plan for Advance of the Tunnel (PAT) method, which allows adapting the design and control parameters of the future stretches of the tunnel to the results of the stretches already finished, using the monitoring data base. Numerous criteria are given to identify the key parameters, necessary for the PAT procedure. Best practices of excavation management with the help of real time monitoring and control are also provided. Furthermore cost and time evaluation systems are analysed. Finally, contractual aspects related to construction by contract are investigated, for best development and application of models more appropriate for tunnelling-construction contracts. The work will be of interest to practising engineers, designers, consultants and students in mining, underground, tunnelling, transportation and construction engineering, as well as to foundation and geological engineers, urban planners/developers and architects.
Book Synopsis High-Temperature Viscosity Performance of Crumb-Rubber-Modified Binder With Warm Mix Asphalt Additives by : Hainian Wang
Download or read book High-Temperature Viscosity Performance of Crumb-Rubber-Modified Binder With Warm Mix Asphalt Additives written by Hainian Wang and published by . This book was released on 2012 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of crumb-rubber modifier (CRM) in asphalt mixtures has been proven to increase the viscosity of CRM binders. In recent years, warm mix asphalt (WMA) additives have been employed to CRM binders to lower their viscosity at high temperatures, allowing a decrease in the mixing and compaction temperatures. The objective of this research is to investigate the viscosity and storage stability of rubberized WMA binders with different tire rubber concentrations and WMA additives. The tire rubber of 40-mesh, with concentrations of 10 %, 15 %, 20 %, and 25 % by weight of a Superpave performance grade (PG) 64-22 asphalt binder, were used in this study along with the WMA additives, such as Sasobit, RH and Advera. Viscosity tests were conducted on the rubberized WMA binders using the rotational viscometer at four temperatures (135, 160, 177, and 190°C). The statistical analysis of variance (ANOVA) was applied to quantify the respective effects of the influencing factors on the CRM binder's viscosity. The test results indicated that the addition of crumb rubber could greatly increase the viscosity of asphalt binders, which could be improved continuously at increased crumb-rubber concentrations. However, when considering different WMA additives, the crumb rubber showed different effects on the viscosity of the binder. The three WMA additives could all reduce the viscosity of the CRM binder; in addition, RH had the most significant effect on viscosity reduction. It was also found that the CRM binders with WMA additives had good storage stability. For example, the viscosity of the CRM binder with 10 % rubber concentration and RH only increased by 3.8 % after being stored for 4.5 h.

Book Synopsis Evaluation of Performance on Crumb-Rubber-Modified Asphalt Mixture by : Yuming Dong
Download or read book Evaluation of Performance on Crumb-Rubber-Modified Asphalt Mixture written by Yuming Dong and published by . This book was released on 2012 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the performance of crumb-rubber-modified (CRM) asphalt mixture. Two different asphalt mixtures containing two types of asphalt binder (#90 original asphalt and CRM asphalt) were used to prepare Marshall specimens and determine optimum asphalt content. Mechanical performances of asphalt mixes were evaluated by the wheel rutting test (WRT) (dynamic stability (DS)), midpoint beam bend test (MBBT), at low temperature, and indirect tensile test (IDT), at the freezing and thawing cycle. Superpave gyratory compactor (SGC) specimens were also prepared for the modulus test. Using the simple performance test (SPT) and universal testing system (UTS), viscoelastic mechanical characteristics were evaluated by static and dynamic modulus tests. Static modulus (E) data were measured by the un-confinement uniaxial compression test according to the specification of China. Moreover, dynamic modulus (E0) data were obtained by SPT. The crumb-rubber content varies from 0, 10 %, 20 %, to 30 % at the static modulus test. Two test temperatures were selected for the dynamic modulus test. The results indicated that the CRM asphalt mixture performs better than the standard asphalt mixture on dynamic behavior, rutting resistance, cracking resistance, and moisture stability.
