Reuse of Plastic Waste in Road Construction Essays
Reuse of Plastic Waste in Road Construction Essays Reuse of Plastic Waste in Road Construction Essay Reuse of Plastic Waste in Road Construction Essay What is plastic A material that contains one or more organic polymers of large molecular weight, solid in its finished state and at some state while manufacturing or processing into finished articles, can be shaped by its flow. Types of plastics 1. Thermosets. 2. Elastomers. 3. Thermoplastics. NATURAL RESINS solids or semi solid materials light yellow to darkbrown in colour carbon, hydrogen and oxygen. globules on the bark . SYNTHETIC RESINS derived primarily from petroleum. polystyrene, polyesters and acrylics sed in the manufacture of varnishes, plastics, adhesives and rubber. Various Resins Of Plastic Polyethylene terephthalate (PET,PETE) Density polyethylene(HDPE) Vinyl(Poly vinyl chloride or PVC) Low Density Polyethylene(LDPE) Polypropylene(PP) BASIC PROCESSES Segregation . Cleaning process . Shredding process . Collection process . 2. Wet Process Waste plastics by direct mixing with hot bitumen at 160Aââ¬Å¡Aà °C Mechanical stirrer is needed Addition o f stabilizers and proper cooling. Since the wet process require a lot of investment and bigger plants Not commonly used.. ADVANTAGES OF PLASTIC ROAD Use higher percentage of plastic waste. Reduce the need of bitumen by around 10%. Increase the strength and performance of the road. Reduce the cost to around Rs. 5000/Km. of single lane road. Generate jobs for rag pickers. Develop a technology, which is eco-friendly. DISADVANTAGES OF PLASTIC ROADS 1. Cleaning process Toxics present in the co-mingled plastic waste would d start leaching. . During the road laying process But the presence of chlorine will definitely release noxious HCL gas. 3. After the road laying The components of the road, once it has been laid, are not inert. It is opined that the first rain will trigger leaching. As the plastics will merely form a sticky layer, (mechanical abrasion). once the road is started to be used will cause the release of fine polymer particles. When air-borne, these will cause a particulate problem. CONCLUSION Plastic will increase the melting point of the bitumen use of the innovative technology not only strengthened the road construction but also increased the road life Help to improve the environment . plastic road would be a boon for Indiaaââ¬Å¾? s hot and extremely humid climate where durable and eco-friendly roads which will relive the earth from all type of plastic waste Reference: seminarprojects. com/Thread-reuse-of-plastic-waste-in-road-construction-full-report#ixzz1gliWsmVK vvvvvv

Difference Between a Book Report and A Book Review
Difference Between a Book Report and A Book Review The difference between book report and book review is critical, so you have to pay close attention to what you are expected to come up with: if you need to sum up and enumerate, youre in for a book summary (book report), but if you need to analyze, you want to write a book review. There is a great deal of confusion when it comes to discussing book reports and book reviews. As a matter of fact, these two terms keep used quite interchangeably, while a deeper dig-in shows some principal differences between the two. If you submit a book report and you were asked to write a book review, your grade is most likely to go down. The opposite situation, i.e. when you submit a book review instead of a book report, may also entail adverse consequences. Book review writing is believed to require greater intellectual effort than book reports, thats why your marker will most likely forgive you this mistake. HOW TO WRITE A BOOK REVIEW Speaking of differences, first of all, you will have to understand that a book report is simpler (a more primitive if you will) kind of writing, where you have to narrate re-tell the story. A book report is practically identical to a book summaryà and they can be used interchangeably. In contrast,à a book review requires you to analyze the book and see beyond the obvious. In it, you will need to examine its contents, understand the plot, the main message of the book, see if the author has managed to convey the message to the reader; you will also have to state strong and weak sides of the book and say whether or not you like it. More differences between the two terms are as follows: LENGTH.à Book report will usually take 200-250 words. Book reviews will range from 200 words if its a simple book to 1000+ words if its a piece of scholarly literature that needs thorough analysis and evaluation. ACADEMIC LEVEL.à Book report is considered to be a K-12 level assignment. Book review is more of a college-level type of assignment. STRUCTURE.à The structure of two papers resemble one another: first off, you would need to introduce the author, the book, state when and who the book was published by. You would need to mention characters, mention the plot, genre, and major themes. MESSAGE.à If you write a book report, you would need to simply sum up the book plot, characters, state major themes and say a few words about the major characters. If you are writing a book summary, the main idea is to say whether or not you like the book, whether or not you would recommend this book to other readers and why.
