Rubberized Asphalt
In this report, I will be talking about rubberized asphalt. I will talk about how this product first came about, and how it is made. Also I will talk about what the advantages of using this are and other information about it. In the world, there are many roads leading in every direction. Over time people began to develop ways so that it would be easier to travel. Starting from dirt roads, and using the river system and railroad, we have come a long way. Cars were not even thought of as a major way of transportation until today. With the growth of car companies there would be many tires that would come and go. Roads would be created spanning the length of the country. This would eventually lead to many tires being used and dumped into the junkyards and landfills, as well as roads crumbling over time to the great forces or nature with few people wondering how they could make a better road that could last longer then before. After a great span of time someone finally found out how to put it all together. They found out how to put use of the old tires in the junkyard along with a way to stop the roads from being weak and allowing them to have a greater life span with less cracks.
After this material is put down, cars cannot drive on it for an hour or longer. This is so that the mixture will be even and that no other place will have more rubber then another part. In traffic filled areas it could cause traffic for a short term. ame from asphalt, which is a mixture of aggregate, sand, bitumen, and other various additives. The three different ways are the wet process, the dry process, and the terminal blend process. This product can also be used in cold climates. Other names for it are the McDonald process, and the "Arizona" process. Since the asphalt can exhibit more permeability that makes it age at a much slower rate and also decrease oxidation. One example would be with the mosquitoes. There are disadvantages to this material also. The rubberized asphalt must be able to cool down to 150 degrees. It is a blend of asphalt cement, old claimed tire rubber, certain amount of additives in which the rubber component is at least 15% by weight of the total blend and has reacted sufficiently to cause swelling in the rubber particles. Rubberized asphalt has been tested in many various cold climates and has passed all the tests. This slows down the work for other companies that need work done with there asphalt jobs, but cannot get it at that certain plant that is making it.
