Recycled Tyre Rubber Modified Bitumens for road asphalt mixtures: A literature review

Effects of preparation process on performance of rubber modified asphalt

“…In recent years, road damage phenomena such as pavement rut, bleeding and bulling have happened very frequent and become increasingly serious. Therefore, how to improve the performance of asphalt mixture and prolong the service life of pavement becomes an important research direction of the road building materials [1].…”

“…In fact, waste can be turned into treasure as the effective components contained in waste rubber tire can be used for asphalt modification. Studies on rubber modified asphalt have attracted broad attention of scholars all over the world [1,2].…”

“…In recent years, road damage phenomena such as pavement rut, bleeding and bulling have happened very frequent and become increasingly serious. Therefore, how to improve the performance of asphalt mixture and prolong the service life of pavement becomes an important research direction of the road building materials [1].The amount of waste rubber tire has been increasing along with the number of cars growing in China. Relevant data show that there are new 250 million waste rubber tires totaling 520 tons in 2010.…”

“…In fact, waste can be turned into treasure as the effective components contained in waste rubber tire can be used for asphalt modification. Studies on rubber modified asphalt have attracted broad attention of scholars all over the world [1,2].Waste rubber tire is an ideal asphalt modifier, including natural rubber, synthetic rubber, carbon black and other ingredients. It's shown in some research papers that adding rubber particles into asphalt can significantly improve the performance of asphalt and its mixture, such as enhancing durability of pavement, increasing the toughness and elasticity recovery of asphalt, improving the aging resistance and anti-rutting ability, and reducing the pavement noise etc.…”

Effect of Crumb Rubber as Coarse and Fine Aggregates on the Properties of Asphalt Concrete

“…Two dissimilar crumb rubbers were approved: One produced by the ambient production method and the other from the cryogenic process. Presti (2013) viewed the technology as successful based on the evidence demonstrated by roads built in the last 40 years with the rubberized asphalt mixture obtained through the so-called ''wet process'' which involves the utilization of the Recycled Tire Rubber Modified Bitumen's (RTR-MBs). Since the 1960s, asphalt mixtures produced with RTR-MBs have been used in different parts of the world as solutions for different quality problems and, despite some downsides, in the majority of the cases, they were demonstrated to enhance the performance of road pavement.…”
