This book was released on 1989 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this in-house study was to determine if methylene chloride (CH2Cl2) can be used to recover asphalts using the Abson Method (AASHTO T 170 and ASTM D 1856), and to compare its effects on recovered binder properties to those of trichloroethylene (C2HCl3). Current nationally standardized test procedures (AASHTO and ASTM) do not allow methylene chloride in the Abson Method. Virgin paving grade asphalts and hardened asphalts were used in this evaluation. Hardened asphalts consisted of paving grade asphalts aged by the thin film oven procedure, paving grade asphalts extracted from aged loose mixtures and cores, and coating grade roofing asphalts. The following tests were performed before and after recovering the asphalts from trichloroethylene or methylene chloride: (1) penetration at 25 deg C, (2) viscosity at 60 deg C, (3) viscosity at 135 deg C, (4) high pressure gel permeation chromatography, and (5) infrared spectral analysis.

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.
