| Summary: | The management of scrap tires has become a growing problem in recent years.
Scrap tires represent one of the several special wastes that are difficult to handle. Thus,
there is a need to solve the rubber disposal problem. Recently, scrap rubber has been used
in asphalt highway construction, but there are still some limitations in the rubber
application. Scrap tires are believed to be able to produce better performance asphalt
pavement, which can provide quieter riding environment, and less defective pavement.
The purpose of the research is to determine the performance of the asphalt pavement with
the existence of scrap tires, compare with the conventional asphalt pavement. The
research will be conducted by adding the scrap tires to substitute small part of fine
aggregate in the asphalt mixtures. The scrap tires will be cut into small pieces and mix
together with the conventional mixtures of coarse and fine aggregates as well as filler.
The rubber modified asphalt are designed using Marshall Mix Design and tested using
Wheel Tracking Test and Beam Fatigue test to evaluate pavement performance on fatigue
and permanent deformation. The main purpose to conduct the research is to enhance the
conventional pavement performance. It is successfully determine the performance of
Rubber Modified Asphalt mixture is better than the conventional mixture. Perhaps the
research can help to promote the used of scrap tires in asphalt pavement for better
performance. |
