Using Porous Asphalt Surface Surfaces

These tasks go hand and hand with the City Public Works Drainage Division which administrates permits, and is responsible for the implementation and the execution of stormwater best management practices through the use of various resources such as personnel, and medium and heavy equipment. Public Works maintains more than 350 miles of storm sewer drainage system within the City and approximately 150 miles of drainage ditches and thousands of storm water inlets. Public Works crews work continually throughout the year removing trash and debris, mowing drainage ditches, vacuuming stormwater inlets, as well as other tasks to maintain a healthy drainage infrastructure. Unfortunately, the City is faced with the challenges of sustaining its extensive MS4 program and existing drainage infrastructure due to the lack of additional financial resources. Certain sections of the City’s drainage system are more than 50 years old and deteriorating. As the City continues to grow and expand, the need for repairs, retrofitting and maintaining the City’s existing infrastructure is as equally important as creating new capital projects.

Many of these impervious surfaces have drainage systems that run directly into the watershed. As shown above in the center picture, there is direct drainage from the street to the watershed with no type of filtration, which in return has cause the glistening polluted puddle in front of the drainage pipe.

Although some individuals and governmental bodies sway towards minimizing and controlling usage, some other groups believe it is best to eradicate the usage of road salt altogether. Both of these are good suggestions and will definitely address the problem. However it is important to evaluate any suggestions and understand how the factors discussed above contribute to the increased use of road

Road runoff is a major source of nickel, copper,zinc, cadmium, lead and polycyclic which are created as byproducts of gasoline and other fossil fuels. De-icing chemicals Road salts,primarily ,chlorides of sodium, calcium or magnesium that can be toxic to sensitive plants and animals.

The most important point of this submission was that it was uploaded to Youtube, allowing it to be seen by the world and inform the general public about these low-impact development technologies. Even I didn’t know some of the benefits and applications of green roofs and permeable pavement before I started this work term so I hope that these videos will introduce the general public more about these technologies. As cities continue to grow, green roofs, permeable pavements, solar panels and other low-impact development technologies have a lot of potentials, so I hope through videos like these they will be more well known and accepted so that our communities could become more green and sustainable in the

Storm water is a great danger to the environment because it does not receive any treatment before entering waterways. A storm can overload the system, causing it to reach its max capacity. The water treatment plant is then forced to let the overflowing, untreated, water dump into the river. This leads to an almost opaque water, like that found in the Puget Sound. There is an average of 900 billion gallons of untreated sewage water entering larger bodies of water each year in the United States (Barnett). The rain that falls on surfaces drains into bodies of water through storm water collection systems, usually, without treatment. There is a strong relationship between concrete thickness and imperviousness in residential areas, leading researchers to believe that roads create impervious surfaces. When rain down the streets and rooftops, it absorbs all the harmful materials from those surfaces and flows into the major bays and the Puget Sound. The Environmental Protection Agency estimates the remodeling of the aging water system would cost between $300 billion to $1 trillion over the next 20 years (Barnett).

The condition of our roads the past couple summers has been pretty poor. Many of the main streets are filled with large pot holes and loose

Old asphalt often forms crumbles along the edges. The crumbles continue to spread and get worse

Storm water runoff is caused by rain draining through areas of pollution and then taking it into large bodies of water, this is one of the major water pollution areas. Storm water pollution effects every living organism on earth. With so many contaminates going into the water that we bathe in and drink, it is becoming a major problem. With 70% of the Earth being covered in water, this is every ones concern. Thomas M. Parris said in the article Managing Storm-water, "Storm-water run off is a major source of water pollution. When rain falls or snow melts, it picks up debris, chemicals, dirt, and other pollutants and often flows directly into lakes, streams, wet lands, and coastal waters.". With the proper analysis of risk and management, storm-water run off can

As you can see, road salt is effective but has its negative points. Not only can it harm aquatic life and bodies of water, but also roads, bridges, soil and vegetation. The questions here are, are the benefits of using 5 million tonnes a year of salt worth all of the negative aspects it brings.

You can’t just use any paver though. To make sure you get the right paver you want to look at its thickness. Different sizes will be able to hold different things. Like “Most planks and slabs are not suitable for vehicular applications” (Designing the Pavement System). But you also do not want to overkill it and use pavers that are too thick. This would make your costs go up by a lot. It will also take more time to install and get the pavers delivered to you. It will decrease the amount that will be able to fit on a pallet, thus decreasing the amount you can fit on a Semi truck. To figure out the thickness of paver required for what you are trying to make you would want to find out the Aspect ratio.

Both of these officials echoed the beliefs of B & E Seal Coat Products. We have been manufacturing a line of environmentally safe sealants since 2011. Our Safe Seal products are asphalt-emulsion sealants that provide extraordinary protection with none of the risks associated with coal-tar sealants or “false flag” sealants that are advertising as eco-friendly while still containing exceedingly high levels of PAHs. In addition, we also sell many of the tools and products needed for sealcoating, parking lot markings and asphalt repairs. You can submit our online form to request a free quote or call (616)

If you're planning a new parking lot for your place of business, one thing you must consider is water runoff. If rain can't seep through the parking lot surface, it must be diverted to a pond or storm sewer. The solution to this problem is to have the contractor use porous asphalt so water can drain through the soil naturally. Here are a few things you should know.

What is kinetic sand? Kinetic sand is a building toy that can be manipulated into different shapes and sizes. Kinetic sand wasn’t always meant for children. It was originally used for sculpting but now it is often sold as play sand for children. Kinetic sand can be molded, sticks mostly to itself and doesn’t dry out. This is probably why it is popular among children. Kinetic sand is made of sand (98%) and PDMS (2%). Polydimethylsiloxane (PDMS) is one of the popular silicon-based organic polymer. It is used in a variety of products such as, diaper rash cream, hair gels and different types of cosmetics. Kinetic sand itself isn’t in the Wendy’s chicken mcnuggets and french fries but the ingredients to make it is, that would be PDMS. PDMS is also

Have you ever felt depressed after you went to oil station with high oil price? Los Angeles, the place we are living, has abundant oil to produce. Why we are still suffering a high oil price even Los Angeles is one of the oil production places? In the center of Los Angeles, we had found an integrated tar pit left over by history. Do you know what the purpose of tar pit is? In the United States, most of asphalt was transported from Los Angeles and asphalts were used for road construction. As asphalt and gasoline are the subsidiary products of petroleum, the economic development in Los Angeles has boomed since 1900s and became the biggest base of petrochemical industry.
