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 asphalt 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 ...Download file to see next pagesRead More

A Woman on a Roof

...him and he believed that if he approached her she would be good to him. He keeps on fascinating about her until he gets rejected. “A Woman on a Roof” can be considered as a masterpiece written by Doris Lessing as it is a perfect reflection of the society towards the mid twentieth century. Lessing uses the roof and the happenings on its either side to make her stand understood by the reader. The woman finally speaks towards the end of the story and tells Tom off. Through this, Lessing has tried to portray the voice of women. Feminism is the main theme behind her work and she has perfectly portrayed that in her story. The men in the story hate the women and keep on getting aggressive...

Roof Rain Water Harvesting

...Water Engineering - Rain Water Harvesting Introduction Roof top rainwater harvesting refers to the process of collecting, conveying, storing and distributing the natural water for various non-potable applications. The objectives of such type of installations are to compensate for the reduction in the volume of water due to large scale building construction process. As the construction of car park requires large area of covered space it could limit the infiltration of rainwater which other wise would have infiltrated into the ground and enriched the prevailing ground water table. The various applications for which the water collected from the roof top collection systems usually used are...

...around the world. Several major research projects have taken place and are currently in progress. The National Cooperative Highway Research Program has a major study currently underway to evaluate skid resistance. The study is not yet complete, but it does show promise in offering improvements in skid resistance through the use of finer grade aggregates. However, due to the fine grade of the aggregate, water may be slow to run off and create a wet condition hazard. Friction is created where the rubber meets the road. The composition of the open coarse grade and its components are a first consideration. The microtexture, the fine aggregate in an asphalt mixture, is most influential force creating the...

Hot Asphalt Mix

...a permanent, exceptional pavement that has 2% air void going hand in hand with 98% air compaction. Conclusion A design of the mix of asphalt that is constituent of engineering characteristics that are related on the performance is needed. Compactor of Super pave’s gyratory has a crucial part in the production of compaction of laboratory asphalt mix that represents field compaction. It was hard to meet the Super pave’s air void and compaction due to possibility of the sand in the mixes. When the result showed air void of 2.618 there were different figures of the other results that ranged from 2 to 8. This shows that the mixtures did not meet the requirement of air void. This...

.... The percent of water absorbed for both specimen C and D was less than 3 percent consequently there was no need for paraffin-coated. The samples fall within PennDOT’s acceptance criteria because they have percent of air voids around 4% and 96% compaction. However, C proves to be the best sample since its values for percent air voids (3.22) and compaction (96.78%) are closer to PennDOT’s acceptance criteria. This means that design mixes C and D are suitable for asphalt pavement since they give assurance on the required degree of compaction and percent air voids in compacted bituminous samples.... G.

These include, a hot and dry weather, which characterizes the region, Flagstaff. In this regard, the idea is to have a roof that allows for high-efficiency ventilation, one that makes use of rapidly renewable materials, and finally on that only utilizes certified wood products. Notably, the roofing system should preferably allow for solar photovoltaic systems (Vassigh, Özer & Spiegelhalter, 2013). Based on these analysis points it then becomes critical to weigh the roof’s properties against the identified...

Pavement Design

...variable that factors in the type of material to use for each layer. For design purposes, layer coefficients are typically determined empirically based on the performance of the material. Agencies often set specific layer coefficient values for commonly used materials as a standard design policy. Some typical layer coefficient values are:Hot mix asphalt – 0.44, road mix (low stability) – 0.20, aggregate base – 0.13, engineered fill – 0.10 Since the layer coefficient can be affected by material properties as well as the position of the layer in which the material will be used, in some cases different values might be appropriate for local conditions. Drainage Coefficient A...
