Special Issue Information

Dear Colleagues,

The development and application of high-performance asphalt and asphalt mixtures have emerged as crucial components in modern construction, particularly for infrastructure such as roads, bridges, and airports, where long-term durability and environmental sustainability are paramount. High-performance asphalts are designed to withstand extreme weather conditions, heavy traffic loads, and other stresses that traditional materials might fail against. They offer superior resistance to rutting, cracking, and ageing, thus extending the lifespan of pavement structures. The utilization of high-performance asphalt mixtures incorporates innovative additives and modifiers that enhance material properties, including rubber, polymers, reclaimed asphalt pavements (RAP), cement, et al. These components contribute to the mixtures' flexibility, strength, and recyclability, further reducing the environmental impacts. In construction, the application of these technologically enhanced asphalts ensures a faster, more efficient paving process, with reduced maintenance requirements and greater cost-effectiveness over time.

Therefore, this Special Issue welcomes the submission of experimental, modelling, and in situ studies related to high-performance asphalt and asphalt mixtures, pavement construction techniques, and field performance. The articles presented in this Special Issue shall clearly identify their novelty and contribution to the field.

As a plasticizer, vegetable oil can improve the compatibility between straw fibers and an asphalt matrix and promote the uniform dispersion of fibers, thereby improving the viscoelastic properties of the composite material. This paper selected three vegetable oils: tall oil, rapeseed oil, and palm wax. Through dynamic shear rheology tests, low-temperature bending beam rheology tests, contact angle tests, and infrared spectroscopy tests, the vegetable-oil-reinforced straw fiber modification was analyzed from different points of view. The research results show that palm wax significantly improves the high-temperature rheological properties of straw-fiber-modified asphalt but has a negative impact on low-temperature properties. Tall oil can most significantly improve the low-temperature rheological properties of straw-fiber-modified asphalt. Rapeseed oil has the most obvious effect in improving the adhesion and water damage resistance of straw-fiber-modified asphalt. In addition, the research shows that all three vegetable oils exist in the modified asphalt in adsorbed form, and no new compounds are generated. These research results provide theoretical guidance value for the application of straw-fiber-modified asphalt pavement in different environments. Full article
