  1. The paper focuses on exploring the potential for effective testing of asphalt mastics in the full range of temper-atures using the Dynamic Shear Rheometer (DSR) apparatus. Six various types of asphalt mastics were selected to enable the evaluation of the effects of hydrated lime and bitumen modifica-tion, both before and after aging. Different DSR tests covered the whole range of service temperatures from...

  2. Rest periods between cyclic loads can lead to recovery of damage and extension of fatigue life. This phenomenon is referred to as healing. Healing is clearly observed in bituminous materials, such as asphalt mastics, which belong to the components of asphalt mixtures. Due to the nature of road pavement traffic loading, which is characterized by series of intermittent pulses with rest periods, consideration of healing is necessary...

    This paper investigates the effect of temperature on WIM-collected data using the steering axle load spectrum (SALS) and two datasets. The first dataset, provided by the WIM system operator, contains detailed raw data, while the second, supplied by the road authority, includes less detailed information but covers 46 stations with various sensor types and configurations: single-line bending plates and two-line quartz piezoelectric...

    Weigh-in-motion systems (WIM) serve as valuable sources of traffic load data. The determination of axle load spectra using WIM data is pivotal for calculating load equivalency factors and predicting pavement distresses through M-EPDG. Among various factors affecting WIM accuracy, temperature changes stand out as particularly influential. This paper examines the influence of temperature on WIM-collected data, utilizing the steering...

    This article presents the development process of designing and testing poroelastic pavement based on highly polymer-modified bitumen. Poroelastic wearing course was composed of mineral and rubber aggregate mixed with highly polymer-modified bitumen, in contrast to previous trials, during which polyurethane resins were mainly used as binder, which led to several serious technological problems concerning difficult production, insufficient...
