Many state departments of transportation have adopted the Superpave PG specification since the completion of the Strategic Highway Research Program in 1993. A much wider range of crude oil sources and binder modification techniques are being used now to produce asphalt binders. Although asphalt binders used these days still meet the requirements of the PG specification, many premature failures have been reported by many states. Texas Department of Transportation (TxDOT) initiated a study on re-refined engine oil bottom (REOB) in 2015. The objectives of this study were to establish REOB detection methods and recommend maximum allowable amount of REOB in asphalt binders and seal coat binders. Based on existing literatures, researchers developed and verified scientific methods to detect and quantify the amount of REOB in both asphalt binders and seal coat binders using a handheld or a benchtop X-Ray Fluorescence (XRF) instrument. Furthermore, a comprehensive study was performed to define the impact of REOB on asphalt binders, asphalt mixtures, and seal coat performance. Multiple sources of binders, aggregates, and REOB (including recycled binders, PPA, and GTR) were used in the evaluation. Laboratory test results clearly indicated that the addition of REOB has detrimental effects on rutting, cracking, and seal coat adhesion properties. Not only should the current upper limit of 5 percent REOB in asphalt binders be kept, but an upper limit of 5 percent REOB in seal coat binders needs to be established. The implementation of these XRF tools and recommendations on the upper limits of REOB in binders will make pavements last longer as intended.

Advances in Materials and Pavement Performance Prediction contains the papers presented at the International Conference on Advances in Materials and Pavement Performance Prediction (AM3P, Doha, Qatar, 16- 18 April 2018). There has been an increasing emphasis internationally in the design and construction of sustainable pavement systems. Advances in Materials and Pavement Prediction reflects this development highlighting various approaches to predict pavement performance. The contributions discuss links and interactions between material characterization methods, empirical predictions, mechanistic modeling, and statistically-sound calibration and validation methods. There is also emphasis on comparisons between modeling results and observed performance. The topics of the book include (but are not limited to): • Experimental laboratory material characterization • Field measurements and in situ material characterization • Constitutive modeling and simulation • Innovative pavement materials and interface systems • Non-destructive measurement techniques • Surface characterization, tire-surface interaction, pavement noise • Pavement rehabilitation • Case studies Advances in Materials and Pavement Performance Prediction will be of interest to academics and engineers involved in pavement engineering.

Waste Engine Oils presents a complete description of the field of engine used oils, widely collected in the networks of services-stations and garages. It describes the manufacture of base oils in refineries, and mentions the main additives playing an essential role in the quality of the marketed finished oils. The organization of the different systems of collecting in order to obtain a waste oil regenerable or used as fuel are explained. This book covers the main operations of physical and chemical treatments required in waste oil regeneration by covering the fundamental principles techniques such as vacuum distillation, solvent deasphalting, and ultrafiltration. A wide part is dedicated to applications with the description of about twenty processes. In addition, the book describes several types of energetic valorizations which concern a quite important fraction of the collected oil volume. * Comprehensive approach of the waste oil valorization * Overview of chemical engineering operations applied to waste oil * Objective view of the given information on a subject giving rise to competitiveness between the two routes of volorization

For four decades, Petroleum Refining has guided thousands of readers toward a reliable understanding of the field, and through the years has become the standard text in many schools and universities around the world offering petroleum refining classes, for self-study, training, and as a reference for industry professionals. The sixth edition of this perennial bestseller continues in the tradition set by Jim Gary as the most modern and authoritative guide in the field. Updated and expanded to reflect new technologies, methods, and topics, the book includes new discussion on the business and economics of refining, cost estimation and complexity, crude origins and properties, fuel specifications, and updates on technology, process units, and catalysts. The first half of the book is written for a general audience to introduce the primary economic and market characteristics of the industry and to describe the inputs and outputs of refining. Most of this material is new to this edition and can be read independently or in parallel with the rest of the text. In the second half of the book, a technical review of the main process units of a refinery is provided, beginning with distillation and covering each of the primary conversion and treatment processes. Much of this material was reorganized, updated, and rewritten with greater emphasis on reaction chemistry and the role of catalysis in applications. Petroleum Refining: Technology, Economics, and Markets is a book written for users, the practitioners of refining, and all those who want to learn more about the field.

In the recent past, new materials, laboratory and in-situ testing methods and construction techniques have been introduced. In addition, modern computational techniques such as the finite element method enable the utilization of sophisticated constitutive models for realistic model-based predictions of the response of pavements. The 7th RILEM International Conference on Cracking of Pavements provided an international forum for the exchange of ideas, information and knowledge amongst experts involved in computational analysis, material production, experimental characterization, design and construction of pavements. All submitted contributions were subjected to an exhaustive refereed peer review procedure by the Scientific Committee, the Editors and a large group of international experts in the topic. On the basis of their recommendations, 129 contributions which best suited the goals and the objectives of the Conference were chosen for presentation and inclusion in the Proceedings. The strong message that emanates from the accepted contributions is that, by accounting for the idiosyncrasies of the response of pavement engineering materials, modern sophisticated constitutive models in combination with new experimental material characterization and construction techniques provide a powerful arsenal for understanding and designing against the mechanisms and the processes causing cracking and pavement response deterioration. As such they enable the adoption of truly "mechanistic" design methodologies. The papers represent the following topics: Laboratory evaluation of asphalt concrete cracking potential; Pavement cracking detection; Field investigation of pavement cracking; Pavement cracking modeling response, crack analysis and damage prediction; Performance of concrete pavements and white toppings; Fatigue cracking and damage characterization of asphalt concrete; Evaluation of the effectiveness of asphalt concrete modification; Crack growth parameters and mechanisms; Evaluation, quantification and modeling of asphalt healing properties; Reinforcement and interlayer systems for crack mitigation; Thermal and low temperature cracking of pavements; and Cracking propensity of WMA and recycled asphalts.
