ABSTRACT

Flexible pavement will deteriorate with time and sever distresses will appear because of many factors that might influence its surface particularly in terms of performance and serviceability. For example, excessive traffic loads, variation in temperatures, mistakes in job mix design and poor maintenance. Therefore, three main roads in Samawah city were investigated to evaluate their surface conditions by determining the present serviceability index (PSI). The roads were classified as poor and fair based on surface conditions. Following that, an improvement strategy of production of sustainable mixture was suggested by integrating a certain percentage of glass powder (5-15%) as a part of fine particles content. The modified mixture was tested and compared to the reference mixture in terms of Marshall properties and rutting behavior. With a 10% glass powder added, the findings showed that stability improved by 30% compared to the controlled mixture. On the other hand, flow and air voids content increased as the glass powder content increased. Rutting deformation presented an increasing trend as the content of glass powder increases. Finally, the sustainable mixture met the Iraqi SORB/R9 standards.

Keywords: Glass powder; Marshall tests; Present serviceability index; Rutting performance.
