Using Roof Shingle for Asphalt Pavement Research Paper

Using Roof Shingle for Asphalt Pavement - Research Paper Example In addition it contains between 32% and 42% of a coating filler such as limestone followed by some 28% to 42% of granules. The remaining portion of asphalt shingles is composed of fiberglass, cotton rags, paper and adhesives (Carter, 2008). The use of asphalt is pervasive throughout shingle manufacturing and asphalt constitutes a major part of shingles. The large amount of asphalt present in roofing shingles make these shingles suitable for recycling applications such as for constructing roads. It is estimated that the United States alone manufactures around 12.5 billion square feet of asphalt shingles in a single year (Asphalt Roofing Manufacturer's Association, 2012). In recent years there has been a renewed emphasis to recycle asphalt shingles for road based applications since the shingles contain a large amount of asphalt that can be reused. The Environmental Protection Agency estimates that around 11 million tons of waste is created each year from asphalt shingles in the United States. This waste is comprised of around one million tons of scrap generated by various asphalt shingle manufacturers while around ten million tons of waste is generated from construction sites (Environmental Protection Agency, 2005). This indicates that asphalt shingle supply can be considered as a reliable source for use in road construction given its continuous supply. Another notable aspect is that asphalt shingles and their related waste comprises around 8% of building related waste. Also, asphalt shingles represent around 10% of the waste created from demolition debris. Recycling one ton of asphalt shingles is estimated to conserve one barrel of crude oil (Owens Corning, 2011). Asphalt shingles can be recycled for use in a number of different road based applications including aggregate for road construction, creating pavements, to control dust content on gravel roads etc. It is typical to use asphalt shingles to form the hot aggregate mixture used for manufacturing and paving roads. The amount of asphalt shingles is kept constant at 5% in the aggregate mixture for desirable properties. It has been researched that increasing the amount of asphalt shingles to 7.5% in the aggregate mixtures renders the mixture soft and compromises pavement performance. In addition, using asphalt shingles from construction projects may also result in brittle pavements that might crack especially at low temperatures. For this reason asphalt shingles are typically used where stone mastic asphalt mixtures are required (Newcomb, Stroup-Gardiner, Weikle, & Drescher, 1993). Waste asphalt shingles are recycled by shredding them to half an inch size for batch plants and shredding them to a quarter inch size for continuous feed plants. These materials are added to the overall aggregate mixture before the virgin asphalt is added for binding. The waste shingles that are typically used for creating HMA contain hard asphalt. The combination of this hard asphalt and the soft virgin aspha lt tend to provide highly desirable properties to the overall aggregate mixture. Generally the resulting mixture of waste hard asphalt and soft virgin asphalt provides better stability as well as better resistance to rutting which make it desirable for use in pavements. The departments of transport of a number of states have approved the use of asphalt shingles for constructing roads and pavements. Asphalt shingles have mostly been approved for use in hot mix asphalt (HMA) pavements. While the use of asphal

Should College Athletes Get Paid Research Paper

Should College Athletes Get Paid - Research Paper Example Therefore, they are potential candidates for endorsing and advertising products. It is thus justified to pay them especially noting that athletes have a limited time for fame. Although some critiques argue that it is difficult to determine how much to pay each player, a good mechanism can be devised. It is ironical that athletic organizers can be able to organize college athletics and fail to make a good payment scheme for the players. It is also important to note that most of the college athletes who get into college with scholarship are actually from low-income families. Additionally, most of them are particularly talented in athletics and not in books. Whereas their academically talented counterparts are in class making their future, college athletes are on the field practicing. Therefore, they can hardly get formal employment in the job sector. This makes it important to consider them for payment since athletics is their career. If they do not start to be paid in college, they wi ll hardly make it in life since other better talented athletes will come and replace them with time. However, it is strongly argued that paying college athletes will turn college athletics into businesses such as FIFA. Rich colleges will attract the best talents and other colleges will be denied a chance to nurture their own talents. However, it is worth noting that colleges, including college athletics cannot be run without rules, laws, and regulations. Therefore, efficient and effective control mechanisms can be used to regulate how colleges source for athletes. Figures and statistics show that not all college athletes make to professional teams. This is because college athletes are large in number and therefore, cannot fit in the national or... This essay declares that figures and statistics show that not all college athletes make to professional teams. This is because college athletes are large in number and therefore, cannot fit in the national or professional teams. Although few make it through, those who are not lucky end up in poverty. It is thus justified to pay them while they are still in college. This way, they will be able to save some money for their studies. If well paid, they can even have enough money to start good businesses when they leave college. Those who do not make it to professional teams will thus be able to establish their lives from college savings. It is true that many colleges do not make profits out of college athletes. This paper makes a conclusion that there is a lot of support for pay for college athletes. Since the athletes are the primary source of athletics money, they should then be paid. College athletes are potential candidates for endorsements and advertising products. It is thus justified to pay them especially noting that athletes have a limited time for fame. If they do not start to be paid in college, they will hardly make it in life since other better talented athletes will come and replace them with time. Athletes should be paid while in college. This way, they will be able to save some money for their studies. If well paid, they can even have enough money to start good businesses when they leave college.

Agricultural Wastes as Growing Medium for Pomelo Citrus Grandis Essay Example for Free

Agricultural Wastes as Growing Medium for Pomelo Citrus Grandis Essay The study was conducted to evaluate the use of agricultural wastes as useful growing media for pomelo (citrus grandis) as compared to fertile soil. This agricultural research aims to determine the higher-value uses of agricultural wastes such as animal manure, rice hulls and bran by using it as media for growth of pomelo. The scope included only the utilization native duck manure, fresh rice ban, fresh rice hulls and parboiled rice hulls. The process involves the preparation of pomelo seedlings, preparation of growing media, transplanting method, sustaining growth and monitoring growth of pomelo seedlings in terms of height of the plant and the number of leaves. The pomelo seedlings were observed to survive during the experimentation period. However, the growth varied from one medium to another. To compare the growth rate of pomelo seedlings in agricultural wastes and soil, the t-test was used. It is determined by the mean sample of growth of pomelo plant in the growing to media as labeled T1 to T3 as compared to a standard mean sample, that of the soil, T4. The computed value of t at pgt;. 05 is 1. 23 and 2. 47 less than the critical value 2. 920. This result revealed that there is no significant difference between soil and animal manure-parboiled rice hulls as growing media of pomelo plant. While the greater tcomputed value of T1 and T2 divulged that there is a significant difference between the growth rate of pomelo in the soil and in fresh rice bran (T1) and hulls (T2). This proves that agricultural wastes can be used as growing media for pomelo seedlings. This also affirms that agricultural wastes can help plant breeders to lessen expenses in terms of growing media necessary for plant growth.

The Child by Tiger †Dick’s Character :: The Child by Tiger

The Child by Tiger – Dick’s Character In "The Child by Tiger", Wolfe does a superb job of making the story reveal a truth about human experience. Dick's killing rampage in the short story showed how the human sole has a tendency to become violent. Characterization and excellent choice of tone and mood used in the story display how the Dick becomes violent. Wolfe carefully develops Dick's character in the short story. At the beginning of the short story, Wolfe describes Dick's actions precisely. Wolfe illustrates anything from Dick's movements to his talk. Furthermore, Dick is depicted as an honest hard working and notably talented individual. Wolfe does all of this for a simple reason, to show that any human sole can turn evil, no matter how intelligent, honest, or hard working. For this reason, Wolfe's characterization of Dick is essential to the short story. Without a good characterization of Dick before his sole turns violent, the story would have no meaning and would just be about a mad man. However, with Wolfe's exquisite characterization, the reader find outs how an innocent god fearing man can turn violent. Overall, Wolfe's characterization is key to the short stories meaning. Outstanding tone and mood choice also help show the truth about the weak human sole. First, the Wolfe's informal tone of the story is significant. I believe Wolfe's tone help set up the readers for the shock of what Dick does. However, the tone the author sets is important because of the shock we get, we also see how fragile the human sole is and how it can easily change. In this case, the author's informal and almost ironic tone surprise the reader but also help show the significance of Dick's experience. Second, the author's mood for the story is quiet deceiving. Since the plot of the story is to show how any human sole can turn evil, the author sets an ironic mood. Though the mood is informal, the irony of the situation is of a "good" mad turning "evil". Wolfe sets up this mood by his description and analysis of Dick's character and actions at the beginning of the story. The mood is ironic because when the violent side of Dick comes out, our mood towards the story changes because we are shocked at what has happened to innocent Dick.

My Professional Development At East Central University

The last four years of my life have been a personal challenge for me because I have been living in foreign country. During these time, I had to adjust and learn a new culture by improving my communication skills and understanding the way that people react to specific situations. Moreover, while working on my professional development at East Central University, I have had to overcome the difficulties of being an international student. Some people (sometimes including myself) would think of these difficulties as a disadvantage; however, I consider these complications of being international as a challenge. Therefore, these challenges make me work harder than anybody else, because I like to prove myself to people with my actions, work ethics, and show that I am as proficient and capacitated as any other student. As I mentioned before, the main challenge that I had to overcome was the communication which it represent a vital skill on my profession. As an athletic training student, I was required to perform daily communicate with athletes, coaches and other athletic training personnel about athletes injuries and other problems related with the well-being of the patient. Due to the importance of communicating vital information to others I was determined to work as hard as anybody else, so I can had that personal satisfaction of doing my job well.
