Special Issue Information

Dear Colleagues,

We are currently exploring advancements in the field of polymer-modified asphalt and rubber-modified asphalt, both of which have shown substantial improvements through the incorporation of polymer/rubber materials. Commonly used polymers in this domain include synthetic types, such as styrene–butadiene–styrene (SBS), styrene–butadiene rubber (SBR), and ethylene–vinyl acetate (EVA), among others. These polymers enhance the asphalt's performance, making it increasingly adaptable for a range of applications, particularly in demanding environments. Similarly, rubber materials are often derived from recycled tire rubber, although other sources are also viable.

We are inviting contributions that explore the intricacies of polymer- and rubber-modified asphalt. This includes research that delves into the composition, structure, and properties of these pavement materials. We are particularly interested in studies focusing on the development, evaluation, and practical applications of modified asphalt binders. The goal is to facilitate the creation of sustainable, durable pavements.

Through the exchange of knowledge and insights in these areas, our objective is to advance the field of pavement engineering towards more environmentally friendly and resilient solutions.

Crumb rubber modification of bituminous binders for asphalt concrete mixture production has been shown to provide significant environmental benefits, in terms of reduced embodied carbon, as well as improvement in the mechanical performance properties of asphalt mixtures. Furthermore, even at low dosages of crumb rubber, significant anti-ageing benefits have been reported, in terms of oxidation and ultra-violet light exposure. However, the effect of low dosage crumb rubber modification on the mechanical properties of asphalt mixtures must be understood. This research compared otherwise nominally identical dense-graded asphalt mixtures produced with crumb rubber modified binder at 5%, 10%, and 15% (by weight of the bitumen) and, using short digestion (reflecting field blending) and long digestion (reflecting terminal blending), to two control asphalt mixtures across a range of mechanical properties indicative of stiffness, rutting resistance, fatigue cracking resistance, cold fracture resistance, and moisture damage resistance. It was concluded that 10% was the optimum crumb rubber content and that crumb rubber modification generally improved the mechanical properties of asphalt mixtures, particularly the deformation resistance and the fatigue cracking resistance, which were both improved significantly. However, the effect of crumb rubber content and digestion times was variable. Consequently, the decision to field blend (short duration) or terminal blend (long duration) should be based on logistics, and not on asphalt mechanical properties and the associated mixture performance.

Asphalt modified with treated waste tires has good environmental protection and application value. However, the nano-modification mechanism of crumb rubber (CR) with asphalt is still unclear. This research investigates the mechanism, aging, and interfacial interaction with the aggregate of CR modification asphalt (CRMA). The base asphalt and CRMA (original and aged) and two typical aggregate models were constructed. The accuracy of the model was verified through multiple indicators. The effects of CR and aging on the physical properties (density, compatibility, and diffusion coefficient), mechanical properties, component interaction behavior, and interfacial interactions with aggregates of CRMA were systematically analyzed. The results showed that the CR reduced the diffusion coefficient of asphalt by about 31%. The CR inhibited the movement of the components of asphalt (especially saturate and aromatic), which significantly improved the mechanical properties of asphalt. The compatibility between asphalt and CR significantly deteriorated after aging. The difference in the solubility parameter was about four times that before aging. It is instructive for the regeneration of CRMA. Aging led to a decrease in the shear modulus and Young’s modulus of both base asphalt and CRMA, which verified and quantified the adverse effects of aging on the mechanical properties. Comparing the two aggregates, CaCO3 had a greater adhesion with asphalt than SiO2. The difference ranged from 22.5% to 39.9%, which quantified the difference in the adhesion properties of acid base aggregates with asphalt. This study can provide theoretical guidance for the modification and application of CRMA. Full article

The periodic changes in climatic factors cause the pavement temperature field to change significantly, resulting in fatigue damage to the pavement caused by temperature stress, and the influence depth has a critical value. To reveal the influence range and variation pattern of the rubber-modified pavement temperature field under frequent rainfall and high temperatures, based on indoor tests and the finite element model, the evolution law of different influencing factors and pavement temperature fields was determined by a single factor sensitivity analysis method. The degree of influence of each influencing factor on the pavement temperature field was analyzed using the Pearson correlation. The results showed that with different asphalt mixture initial temperatures, the road surface temperature decreased from 20 °C to 40 °C under sudden rainfall. Repeated rainfall following high temperatures induces cyclic temperature changes 30 mm below the road surface. The pavement temperature difference increased linearly with the dramatic temperature difference, and the changes in the pavement temperature field were small when the number of cycles exceeded 30. The number of cycles and cycle temperature difference were the main factors affecting the changes in the pavement temperature field under dramatic cooling–heating cycles. Full article
