Book excerpt: Three kinds of warm mix asphalt (WMA) additives (Sasobit, Evotherm, and CWA) were used in asphalt-rubber stone matrix asphalt (AR-SMA) to reduce the mixing and compaction temperatures of AR-SMA mixtures. In hot mix asphalt (HMA) mixture designs with the same air voids, the compaction temperatures of AR-SMA mixtures with different WMA additives were determined. The wheel tracking test, low temperature beam bending test, and indirect tensile test were conducted in order to evaluate the high temperature performance in terms of the resistance to rutting, the low temperature performance in terms of the resistance to cracking, and the moisture susceptibility of AR-SMA mixtures with WMA additives. The results indicate that the addition of Sasobit can improve high temperature performance significantly relative to the control mixture (AR-SMA without WMA additive), whereas the other additives yield no significant differences. Three WMA additives have significant effects on low-temperature performance, but they do not significantly increase moisture susceptibility relative to the control mixture.

Available in PDF, EPUB and Kindle. Book excerpt: The intention of this research effort is to evaluate the use of warm mix additives with typical polymer-modified and terminal blend tire rubber asphalt mixtures from Nevada and California. The research effort is broken into three phases that are intended to evaluate the impacts of warm mix additives with typical polymer-modified and terminal blend tire rubber asphalt mixtures from Nevada and California: moisture damage, performance characteristics, and mechanistic analysis. In Phase I of this research effort, mixture resistance to moisture damage was evaluated using the indirect tensile test and the dynamic modulus at multiple freeze-thaw cycles. Laboratory testing was conducted to address the following: (1) the impact of warm mix additive and reduced production temperatures on the moisture damage resistance of asphalt mixtures, (2) the impact of residual aggregate moisture on the moisture damage resistance of WMA mixtures, (3) the impact of warm mix additives on the moisture damage resistance of anti-strip treated WMA mixtures, and (3) the impact of long-term aging on strength gain and the moisture damage resistance of WMA mixtures. A total of one aggregate source, four warm mix asphalt technologies (Advera, Sasobit, Revix and Foaming) and three asphalt binder types (neat, polymer-modified and terminal blend tire rubber modified asphalt binders) typically used in both Nevada and California are being evaluated in this study. This thesis will only summarize the test results and findings of the Phase I of the study for two warm-mix additives: Advera and Sasobit. The evaluation of the other two technologies (i.e. Revix and Foaming) as well as the Phase II testing are still in progress and have not been completed.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability is a cornerstone of today0́9s engineering world. Warm mix asphalt (WMA) and reclaimed asphalt pavement (RAP) are the most prominent sustainable materials in asphalt concrete pavements. WMA is a not a new concept, however new innovations and increased usage of WMA has been spurred by the increased focus on sustainable infrastructure systems. WMA enables reduced production temperatures through the use of wax, water, or other chemical packages. The effects of reduced production temperatures include fuel use and emissions reductions, improved compaction, and possible RAP concentration increases. RAP is the primary recycled product of the aged asphalt concrete pavements and its use leads to reductions in virgin aggregate and asphalt demand. However, significant performance issues can stem from the individual integration of WMA or RAP materials in asphalt concrete. In particular, WMA technologies can increase moisture and rutting susceptibility while RAP significantly increases the stiffness of the resulting mixture. Consequently, quality performance of sustainable asphalt pavements may require the combined use of WMA and RAP to produce mixtures with sufficient stiffness and moisture and fracture resistance. This study evaluates the potential of WMA technologies and their integration with RAP. Initially, an extensive literature review was completed to understand the advantages, disadvantages, and past field and lab performance of WMA and RAP mixtures. Rotational viscometer and bending beam rheometer tests were then used to evaluate Sasobit, Evotherm M1, and Advera WMA modified and unmodified binders. Finally, virgin and 45% RAP mixtures were designed and tested to examine the rutting, moisture, and fracture resistance of WMA and HMA mixtures. The results of this experiment provided several key observations. First, viscosity reductions may not be the primary cause for the availability of reduced production temperatures for WMA technologies. Second, WMA additive properties have a significant effect upon fracture, moisture, and rutting resistance. Furthermore, the addition of RAP to WMA mixtures improved the rutting and moisture sensitivity performance as characterized in the Hamburg and Tensile Strength Ratio testing procedures.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research effort was to evaluate the use of warm-mix additives with modified (polymer-modified and terminal blend tire rubber) asphalt mixtures from Nevada and California. This research was completed in two stages: Sasobit and Advera were evaluated in first stage while Evotherm and Foaming were evaluated in second stage. The three main components of the experimental plan include: evaluation of mixture resistivity to moisture damage, pavement performance characteristics of the mixtures, and mechanistic analysis of the mixtures for simulated flexible pavement. The moisture resistivity of all mixtures were checked by Indirect Tensile Strength (ITS), and Dynamic Modulus (E*) tests. Dynamic Modulus Ratio (ECR) and Tensile Strength Ratio (TSR) were computed at multiple Freeze-Thaw (F-T) cycles for further evaluation of moisture sensitivity of mixtures. Flow Number (FN) and Flexural beam fatigue tests were conducted to evaluate the performance characteristics of WMA additives/technology. The terminal blend tire rubber-modified binder with lime treatment works effectively in resisting moisture damage, rutting, and to significantly-reasonably improve the fatigue life of the WMA Evotherm, Foaming, Advera and Sasobit mixtures. Hence, it is the best solution for the design and construction of sustainable asphalt pavements. The use of terminal blend rubberized asphalt binder is an excellent and economical selection in reducing tire waste and environmental impacts.

Shivaprasad and published by . This book was released on 2011 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study is focused on evaluating the moisture susceptibility of polymerized stone matrix asphalt (SMA) mixtures using moist aggregates and three different warm mix asphalt (WMA) additives. Indirect tensile strength (ITS), tensile strength ratio (TSR), deformation, and toughness were performed to determine the moisture sensitivity of these mixtures. The experimental design included two aggregate moisture contents (0% and ∼0.5% by weight of dry mass of the aggregate), three sources of aggregates (A, B, and C) and three WMA additives (Asphamin, Sasobit, and Evotherm) along with control mixture, and four different types of binders (i.e., PG 64-22 + 10% crumb rubber (−40 mesh CR), PG 64-22 + 15% CR, PG 64-22 + 20% CR, and PG 76-22 with fibers) were used in this study. In total, 384 samples were utilized for the ITS testing in this study. Test results indicated that even though by using 2% hydrated lime as an anti-stripping agent, 32% of the mixtures failed to meet the TSR requirement of 85% as per SCDOT specifications. Mixtures with PG 76-22 + fibers showed improved wet ITS values compared to rubberized SMA mixtures as using moist aggregates. No significant differences in the wet deformation values were observed for mixtures using WMA additives using moist aggregates. Mixtures with 15% CR content showed improved resistance to the percent toughness loss under a warm water bath treatment. Test results indicated that recycled rubberized asphalt binder can be effectively used to improve resistance to moisture-induced damage of SMA mixtures as using WMA technology.

Book excerpt: This book presents the latest advances in research to analyze mechanical damage and its detection in multilayer systems. The contents are linked to the Rilem TC241 - MCD scientific activities and the proceedings of the 8th RILEM International Conference on Mechanisms of Cracking and Debonding in Pavements (MCD2016). MCD2016 was hosted by Ifsttar and took place in Nantes, France, on June 7-9, 2016. In their lifetime, pavements undergo degradation due to different mechanisms of which cracking is among the most important ones. The damage and the fracture behavior of all its material layers as well as interfaces must be understood. In that field, the research activities aims to develop a deeper fundamental understanding of the mechanisms responsible for cracking and debonding in asphalt concrete and composite (e.g. asphalt overlays placed on PCC or thin cement concrete overlay placed on asphalt layer) pavement systems.
