| 摘要： | There is an effort to utilize waste materials in construction processes to diminish the amount placed in landfills. Mixed-color glass, which is not recyclable in the glass industry, has been used in asphalt, but there have been reservations about the durability of a pavement containing glass. The purpose of the project was to install and evaluate field test sections of an asphalt surface mix containing glass, i.e., glasphalt. Although there were no major problems in constructing the sections, the contractor had a problem obtaining a steady supply of glasphalt from the recycling company. The sections have performed satisfactorily for 2.5 years, but some safety problems have been associated with loose glass raveling from the pavement surface. One report of a child being cut and several reports of cut car tires necessitated a monthly sweeping of the curb and gutter sections during their early life, and one street will be repaved because of these difficulties. Because of these problems, the author recommends that glass not be used in surface mixes, especially in urban areas that are subjected to parking and pedestrian traffic. |
