“…The behaviors then are related not only to the viscoplastic strain of the asphalt mixture itself but also to the effect of moisture damage on the asphalt mixture. Hence, the curve here can be used to evaluate the moisture susceptibility of the asphalt mixture [ 20 , 24 ]. In sum, the number of load cycles required for the HWTT permanent strain curvature to change from negative to positive can be considered the number of load cycles at which moisture damage to the asphalt mixture begins to occur (stripping number,

The Hamburg wheel tracking test (HWTT) is widely used to evaluate the performance of asphalt mixtures. According to HWTT specifications, the stripping inflection point (SIP) and the rut depth at a certain number of load cycles are two common indicators for evaluating the moisture susceptibility and rutting resistance of asphalt mixtures, respectively. Although these indicators have been used extensively by several transportation institutions, the reliability and stability in evaluating asphalt mixture behaviors of these indicators have been questioned. To more effectively evaluate the performance of asphalt mixture in the HWTT, this study introduces a novel method of analysis for the HWTT and novel indicators of rutting resistance and moisture susceptibility. The proposed method and indicators were employed to analyze the HWTT results of 14 field core specimens, and the proposed indicators were compared with conventional HWTT indicators to assess their capability of distinction between asphalt mixtures with different performance behaviors in the HWTT. The results indicate that the conventional HWTT indicators cannot effectively evaluate the asphalt mixtures with different performance in the HWTT. By contrast, the proposed analytic method and indicators have significant advantages to effectively evaluate and distinguish the rutting resistance and moisture susceptibility of asphalt mixtures.

“…With considering the conducted research on Pull Off test by researchers, it was observed that the failure type in this test varies from cohesion failure under dry conditions to adhesive or mixed failure under wet conditions. In addition, when the thickness of asphalt binder film on the aggregate surface is high, there is cohesion failure and when the thickness of the asphalt binder film is low, there is adhesive failure [30,31]. Accordingly, Fig.…”

In the current research attempts have been made to investigate the effect of various fillers on the resistance to mastic failure using mechanical and thermodynamic methods. Two types of granite and limestone aggregates with acidic and basic characteristics were used, respectively. Besides, four types of filler including calcium carbonate, hydrated lime, Portland cement and stone powder and two types asphalt binder PEN 60-70 and PEN 85-100 were used. Calcium carbonate and hydrated lime had the most effect and Portland cement and stone powder had the least effect on strength reduction. In addition, the results obtained by modified Lottman test showed that the use of hydrated lime and calcium carbonate increased resistance to moisture damage. The results of correlation coefficients show the necessity of using the effect of filler on cohesion free energy calculation in the surface free energy to investigate cohesion failure in different asphalt mixtures.

“…The results of their research showed that conducting the HWT test according to AASHTO 324 is considered as a good substitute to the dry HWT creep stage test. 16 With millions of dollars allocated annually for pavement rehabilitation and construction, the physical appearance should not be overlooked. Over a design life of 20 years, the constant exposure to radiation is bound to affect the color and appearance of hot mix asphalt.…”

“…This study focused on the cracking strength and rutting resistance of modified HMA. The main testing procedures used for studying the cracking and rutting properties of the samples were ASTM D8044-16: Standard Test Method for Evaluation of Asphalt Mixture Cracking Resistance using the Semi-Circular Bend Test (SCB) at intermediate Temperatures and AASHTO T 324-17: Standard Test Method for Hamburg Wheel-Track Testing of Compacted Asphalt Mixtures.…”

Founded in 1991, the Mineta Transportation Institute (MTI), an organized research and training unit in partnership with the Lucas College and Graduate School of Business at San José State University (SJSU), increases mobility for all by improving the safety, efficiency, accessibility, and convenience of our nation's transportation system. Through research, education, workforce development, and technology transfer, we help create a connected world. MTI leads the four-university. MTI leads the four-university California State University Transportation Consortium funded by the State of California through Senate Bill 1. MTI's transportation policy work is centered on three primary responsibilities: MINETA TRANSPORTATION INSTITUTE Research MTI works to provide policy-oriented research for all levels of government and the private sector to foster the development of optimum surface transportation systems. Research areas include: bicycle and pedestrian issues; financing public and private sector transportation improvements; intermodal connectivity and integration; safety and security of transportation systems; sustainability of transportation systems; transportation / land use / environment; and transportation planning and policy development. Certified Research Associates conduct the research. Certification requires an advanced degree, generally a Ph.D., a record of academic publications, and professional references. Research projects culminate in a peer-reviewed publication, available on TransWeb, the MTI website (http://transweb.sjsu.edu). Education The Institute supports education programs for students seeking a career in the development and operation of surface transportation systems. MTI, through San José State University, offers an AACSBaccredited Master of Science in Transportation Management and graduate certificates in Transportation Management, Transportation Security, and High-Speed Rail Management that serve to prepare the nation's transportation managers for the 21st century. With the active assistance of the California Department of Transportation (Caltrans), MTI delivers its classes over a state-of-the-art videoconference network throughout the state of California and via webcasting beyond, allowing working transportation professionals to pursue an advanced degree regardless of their location. To meet the needs of employers seeking a diverse workforce, MTI's education program promotes enrollment to under-represented groups. Information and Technology Transfer MTI utilizes a diverse array of dissemination methods and media to ensure research results reach those responsible for managing change. These methods include publication, seminars, workshops, websites, social media, webinars, and other technology transfer mechanisms. Additionally, MTI promotes the availability of completed research to professional organizations and journals and works to * = Ex-Officio ** = Past Chair, Board of Trustees
