Compare AASHTO with the ASTM and come with a conclusion which one is more restricted? And do you think it is a valid restriction? And is the restriction valid for our infrastructure durability ?

) List five different advantages of composite materials over conventional materials.

A metallic ore deposit of massive shape is given. The ore is reasonably strong to support itself. The rock above the ore is weak and cavable, and it can break into medium size pieces when unsupported. The ore grade is low and the ore grade distribution is consistent. A high-scale production rate is required. What kind of underground mining methods can be applied to extract this mineral deposit? Explain, in details, the type of mining method that you found for this ore deposit, provide illustrations.

Explain the importance of coefficient of uniformity and coefficient of curvature.

9) Congratulations, you have graduated and scored a job at one of the Charleston area’s largest consulting firms. You have just finished typical first day stuff (choosing your screensaver, arranging your cubicle, etc) when your new supervisor walks in. “Listen –new person, I have to go to a company shareholders pat ourselves on the back meeting this afternoon that just came up three months ago. I scheduled a meeting with a new client today and you need to brief the client on what regulations apply to their site. They own a large industrial/agricultural facility on a few hundred acres. They want to redevelop part of it and keep part of it operating as is; part has existing contamination; part has new chemical and biotechnology operations; part has day to day operations that result in hazardous as well as municipal solid waste. You need to brief them on what three (3) major federal regulations apply to their site and what those regulations mean. Youalso need to let them know specifically which regulations apply to their different on site problems and operations–here is a list of those operations or problems.” Thedescriptions of the specific regulations need to be very detailed.

The list: •Developing a genetically engineered strain of soybeans to resist cold and draught

•Groundwater contamination on a closed parcel of land from TCE contamination in 1945

•Soil contamination from 1980 –all carcinogens –wants to redevelop the site for new use

•Solid waste from the buildings, machine shop, and motor pool

•Hazardous waste (generated daily) from three ethylene crackers

•Low level hazardous waste from two ammonia production facilities

•Final research and development of a novel agricultural pesticide that willlikely hit the market next year•Production of a new food additive/preservative

•Production of a new cosmeticoThe company also wants to know under what act they can be fined if their production disposal practices and storage practices are not appropriate
