“…Based on this situation, rutting distress has been a focus for researchers for many years [1][2][3]. There are many factors influencing the resistance to rutting in asphalt mixtures such as binder type, air void content, and bonding stress between aggregate and binder [4]. Among these factors, asphalt binder plays a key role in the performance of asphalt pavements on both the loading and recovery phase, while much less attention is paid to the recovery phase compared with the loading phase, especially for the study of recovery properties in asphalt binders [5].…”

The recovery property of asphalt binders plays an important role in the performance and service life of asphalt pavements. Since the internal stress is the driving force for the recovery of asphalt binders, the accurate measurement of the internal stress is full of significance. Based on this rationale, this paper aims to measure the internal stress of asphalt binders using a creep and step-loading recovery (CSR) test and characterizing the recovery behaviors by the internal stress. One base asphalt binder and one styrene–butadiene–styrene (SBS)-modified binder are selected in this study. The key elements of the CSR test are carefully designed and its accuracy is verified in three aspects, including the loading conditions, the effect of disturbance by step-loads, and accuracy of measured internal stress. Then, a kinetics-based recovery model is proposed to evaluate and predict the recovery properties of asphalt binders from its causal relationship. The constant-rate recovery activation energy indicates a major difference with nondestructive and destructive loading conditions, while the fast-rate recovery activation energy keeps almost constant regardless of the loading conditions. After that, the healing activation energy is calculated by using the kinetics-based recovery model and the results indicate that SBS modified asphalt binder shows better healing abilities than a base binder.

Libya use a volumetric analysis in designing asphalt mixtures, which can also be upgraded in hot weather. However, the condition of some roads was further down than the required level. Rutting is one of the major defects that occur in asphalt pavements in the southern desert of Libya and severely influence the drive-ability. A questionnaire surveys and laboratory experiments were performed for a few mixes under representative temperature and traffic load. In laboratory, rutting test conducted on two different asphalt mixtures. The first mix used an asphalt binder B (60/70) at optimum bitumen content, another mixture developed using the Superpave design procedure with the same materials and performance asphalt binder grade PG (70-10). The questionnaire survey was distributed to 55 engineers and specialists in the field. The interview was conducted to a few others and the factors that leading to poor performance of asphalt roads were listed. Considering and improving of these factors will play an important role to improve the pavement performances, longer service life and lower maintenance costs. Asphalt concrete pavements (ACP) should use asphalt binder which is less affected by pavement temperature change and traffic load. The properties of the mixture, in turn, affect the pavement performance. Keywords - asphalt mixtures, consistency, performance, (PG), construction.

“…Behnke et al (2019) used the Finite Element simulation of tire-surface short-term and long-term interactions to estimate the long-term rutting performance of pavement structures (Rahman and Gassman, 2009). Rahman and Gassman (2009) developed a correlation between the laboratory measurement of subgrade soil resilience modulus and drop weight deflection tester, and studied the effect of the resilience modulus of subgrade soil on rutting by using the Mechanics-Experience Pavement Design Guide (MEPDG) (Hussan et al, 2019). Radhakrishnan et al (2019) and Son et al (2013) discussed the influence of different combinations of aggregate, binder, temperature and gradation on rut depth.…”

Through a simple performance dynamic modulus test (SPT), standard rutting test, Hamburg rutting test, French rutting test and asphalt pavement analyzer rutting test, the rutting resistance of asphalt mixtures in the middle and lower courses of three semi-rigid base asphalt pavement of Beijing full-scale test track road in China was evaluated. The test results show that the rutting resistance of asphalt mixtures of the middle and lower courses can be greatly improved by using low-grade asphalt, especially 30# asphalt. The rutting resistance of SBS modified asphalt mixtures is also better. The SPT dynamic modulus test can indirectly characterize the rutting performance of the asphalt mixture. The rutting test results of a laser road detection vehicle and 3 m ruler show that the asphalt grade has a significant impact on the rutting performance of semi-rigid base asphalt pavement. Compared with 70# asphalt used in the middle and lower courses, the rutting resistance of the pavement structure can be improved by more than 20%. The result also show that the APA rutting test results can closely characterize the full-scale test track results, which is an optimal test method for evaluating the rutting performance of semi-rigid base asphalt pavement. The research results can provide a theoretical basis and reference for the rational design and rutting evaluation of semi-rigid base asphalt pavement.
