Abstract
Asphalt is the main material used to finish the internal and external streets of cities. Newly emerged in some countries, the use of colors which is added to the asphalt, it would be possible to use in the paving of this material widely in walking pavements, bicycle paths, parks and open spaces. By analyzing the international experiences as well as practical study, by a survey that was done by Iraqi professors in the specialized field of civil and road engineering, as well as architects, urban designer, and landscapers. Non-proliferation of Colored Asphalt and Street Print applications locally, this application has not been used in Iraq till now. There is a lack of knowledge on this subject, hence, the studies and research need to be carried out on this aspect, and find out their suitability for the local environment. The reasons that it is not used in Iraq are: cost of devices, staff, lack of experience, unavailability of materials, laws - culture- traffic engineering and lack of desire for development. It was found that, it is necessary to legislate engineering laws related to traffic engineering and educate vehicle owners about this new culture.
Highlights
Asphalt applications are very effective in residential and commercial evolution
Street coloring is done by using special phosphoric pigments, or by adding the dye to the asphalt mix, the goal is to give the function of corridors or spaces and categorize them with different colors, this method may be used for traffic and road engineering to determine traffic density and speed
[19] There are many companies specialized in colored asphalt produce and develop of colored powder and strengthening pluralism copolymer synthetic resin emulsion liquid preparation, it has lasting and rich colors, excellent performance, longer life and the construction more convenient, inexpensive, both can improve the physical characteristics of asphalt pavement, dust, easy to clean and wash, easy maintenance and other characteristics, and improve the ordinary black asphalt pavement monotony, with the surrounding public spaces with each other, coordination, more suitable for construction applications in the city
Summary
Asphalt applications are very effective in residential and commercial evolution. Through colored asphalts can be obtained texture and style, as well as add safety on the roads, adding architectural and aesthetic values, less expensive than Al-Muqarnas, natural stone or other types of industrial flooring, changing the color of road surfaces reduces the temperature in urban areas. There are many methods to get colored asphalt, using colorful aggregates, recycled glass, iron, slag, through these red, brown yellow, orange and green colors can be obtained in colored asphalt, and it can add various colors to asphalt through the cladding of surface material, such as printing on the streets. These materials break through the gaps and act as adhesives to the asphalt.
