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.

This book was released on 1994 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the laboratory performance of crumb rubber modified mixtures compared to a standard bituminous mixture using performance based test procedures. This study was part of an asphalt resurfacing program for the Seattle Washington area. Laboratory analyses were used to estimate the long term pavement performance of these mixtures in the field. Six mixtures were tested: The standard Class 'A' surface mixture for the Seattle area, Plus Ride II® base course gradation (dry process) using AC 5 and AR 4000W binder types, Plus Ride II® surface course gradation (dry process) using AC 5 and AR 4000W binder types, and ARHM-GG surface course gradation using crumb rubber modified (CRM) AR 2000 (wet process). The performance based tests used on each mixture evaluated the different failure modes a pavement may encounter in the field: fatigue cracking, permanent deformation (rutting), thermal cracking, age hardening, and water sensitivity. Many of the tests used were developed by the Strategic Highway Research Program (SHRP) to test for a mixtures susceptibility in these failure modes. Test results indicate the CRM mixtures performed better than the Class 'A' surface mixture, with respect to fatigue cracking. All of the Plus Ride II® mixtures performed inadequately when tested for permanent deformation. On the other hand, the ARHM-GG surface mixture performed well, even better than the Class 'A' surface mixture with respect to permanent deformation. The ARHM-GG surface mixture showed better low temperature characteristics when compared to the Class 'A' surface and Plus Ride II® mixtures. The CRM mixtures were less susceptible to aging than the Class 'A' surface mixture. Finally, all of the mixtures demonstrated low moisture sensitivity. The final conclusions were made relative to the Class 'A' surface mixture. The ARHM-GG surface mixture performed as well as, and in some cases better than, the Class 'A' surface mixture. The ARHM-GG surface mixture may be used where the Class 'A' surface mixture was specified. The Plus Ride II® base and surface (AC 5 and AR 4000W) mixtures did perform better than the Class 'A' surface mixture in some tests, however it performed worse in others. Therefore, it was recommended that the Plus Ride II® mixture designs be re-evaluated to provide adequate performance in the failed tests.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The accumulation of waste tires generates severe environmental issues. Using crumb rubber processed from waste tires on the pavement could relieve the pressure of waste tire on the environment and improve the performance of the pavement as well. The application of crumb rubber on the pavement using the dry process was proved to be a cost-effective strategy in some projects, however, the interaction between the rubber and asphalt binder was unknown in the rubber modified asphalt mixture using the dry process, especially when reclaimed asphalt pavement was adopted. The performance improvement of the rubber particle to the asphalt mixture was closely related to the interaction. The influence of aging on the characteristics of rubber modified asphalt mixture using the dry process is critical to its long-term performance. The scope of the dissertation is to evaluate the performance of rubber modified asphalt mixture using a dry process when reclaimed asphalt pavement was adopted. The influence of aging on the characteristics of the rubber modified asphalt mixture and the extracted asphalt binder were investigated. This dissertation proposed the volumetric design of rubber modified asphalt mixture using the dry process. The aggregate gradation determination, rubber modified asphalt mixture preparation, design binder content determination, and moisture susceptibility evaluation were proposed. The quality control of the laboratory mixture design procedure was critical to guarantee the consistency of the asphalt mixture design in the laboratory and the results of mixture construction in the plant. The high temperature rutting performance and the low temperature cracking performance of plant mixed and laboratory compacted asphalt mixture was evaluated. The influence of various factors, which included mixture design parameters of the asphalt mixture (nominal maximum aggregate size, reclaimed asphalt pavement content, and asphalt content), rubber modification, mixture air void content, test temperature, and aging procedure, on the rutting and low temperature characteristics of asphalt mixtures were evaluated. Based on the evaluation of different assessment parameters, the rubber addition and the rubber addition and aging were the two most critical factors that influenced the rutting and low temperature cracking performance of different asphalt mixtures. The effect of the Trichloroethylene solvent in asphalt binder was investigated, and the extracted asphalt binder was assessed and compared with the base asphalt binder and rubber modified base asphalt binder. Both the existence of Trichloroethylene and the content of Trichloroethylene had a significant influence on the |G*| of unaged and PAV aged asphalt binder. The Trichloroethylene in the extracted asphalt binder significantly influenced the actual performance of the asphalt binder in the reclaimed asphalt binder, thus potentially compromising the success mixture design. The modified extraction procedure was proposed to improve the accuracy of the extraction procedure. The rubber particles in the asphalt mixture using the dry process were not totally interacted with asphalt binder, only the interacted rubber particles were extracted, and the influence of the interacted rubber particle was assessed. The aged asphalt binder weakened the low temperature performance of the extracted asphalt binder. The aged asphalt binder and rubber in extracted asphalt binder guaranteed the asphalt binder to sustain heavy traffic load, thus improved the permanent deformation resistance of asphalt binder.

This book was released on 2014 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canada has close to 900,000 km of roads, which are key to supporting the Canadian economy as they enable for efficient transportation of goods and services. The Canadian road network should be well maintained and perform to a high standard to ensure the function and growth of the economy and the Country. It is also important to consider sustainability, and more specifically, recycling, when designing the roads. In order to improve on the performance while being sustainable, research is being conducted on the feasibility of using recycled materials in asphalt pavements. One of these materials is crumb rubber, obtained from recycled rubber tires, used as an additive to conventional Hot Mix Asphalt (HMA) to produce Rubber Modified Asphalt (RMA). These tires would otherwise end up in landfills, which is undesirable when considering sustainability. The Ontario Tire Stewardship (OTS), along with the Centre for Pavement and Transportation Technology (CPATT), the Ontario Ministry of Transportation (MTO), and the Ontario Hot Mix Producers Association (OHMPA) have combined their efforts in order to carry out a pilot study on paving roads in Ontario with crumb tire rubber.
