Against the backdrop of low-carbon development, fume emission and high energy consumption generated by hot asphalt and mixtures have gradually failed to meet environmental protection and carbon emission requirements. The developed high-content asphalt recycling technology complies with environmental and low-carbon standards and boasts huge market potential in the future. Our company has pioneered the development of a medium-temperature asphalt rejuvenator and asphalt modification technology. It enables direct addition modification of additives and can also produce special medium-temperature recycled asphalt for recycling projects. Featuring convenient construction, it can raise the reclaimed material incorporation ratio to over 50% and achieve 100% utilization of reclaimed materials. The product quality satisfies the technical requirements for pavement recycling of expressways, arterial highways, municipal roads and other pavements.
