Description
There are about 300 millions waste tires generated each year in the United States. In the state of California alone, more than 40 million waste tires are generated per year. Waste tires take up valuable landfill space and cause significant negative environmental impact. Waste tires can be recycled as asphalt rubber to be used in rubberized hot mix asphalt concrete. Rubberized hot mix asphalt concrete has been used in California for more than 20 years and it has been proven to be a very cost effective paving material when applied properly. However, when using recycled materials in real applications, one faces many challenges, especially, if the knowledge of how to use the recycled materials such as waste tires has not been well disseminated. To overcome these challenges and barriers, teaching materials have been developed to educate university students and professionals about asphalt rubber usages. The teaching modules developed in this study have been taught in real university environments. Several professor training workshops on using asphalt rubber have been given in California of the United States and the training materials were stored on a website. Researchers can use the materials as a source of information while practitioners can use them as guidelines.
