The application of recycled asphalt pavement (RAP) on a large scale is highly promoted to meet the current needs carbon neutrality and sustainable development purposes. However, majority RAP mixture productions are currently relying restoring effects provided by rejuvenators. Therefore, study focuses feasibility using high penetration binder (HPAB) in as replacement for conventional In this stu...

The diffusion between the virgin and aged asphalt binder in recycled mixture is a crucial factor affecting its macro-mechanical performance. In this study, combined model of virgin-aged layered structure was assembled based on molecular dynamics (MD) method. A four-component twelve-category molecule were used to asphalt. behaviors characterized by mean square displacement (MSD), coefficient, re...

Asphalt crumb rubber is a type of pavement material formed by mixing asphalt cement with that derived from recycled tires. This eco-friendly approach aids in waste reduction and promotes environmental preservation incorporating materials into construction. The study aimed to examine the behavior mixtures modified rubber, made blending tire-derived cement. Adding improved performance mixtures, 8...

Millions of tons reclaimed asphalt pavement (RAP) and aggregate or inorganic binder stabilized (RAI) is produced every year in China. The cold recycled mixture (CRM) technology reduces fuel consumption, emissions, cost utilizes the high content RAP. In this paper, six types CRM with varying RAP/RAI composition binders were investigated. laboratory tests included strength indicators, temperature...
