Mechanical Properties of Colored Pavement Containing Metal Oxides

Color in materials leads to surface variety and the increase of architecture power in structure performance. The colored materials are produced to make different view keeping mechanical features of the materials. The present study aims at investigating the features of asphalt and concrete colored Pavement, so different additives (iron oxide, chromium oxide) are used to analyze the behavior of colored covers. Metal oxide was added to Bitumen and cement with weight ratio of 25%, 5%, and 75% making 70 samples with the dimensions of 20*10*20 cm. The samples in the day number seven were tested by three-point bending and Los Angles test. The pavements resistance and the effect of freezing in -18 0C and 23 0C were analyzed. The findings revealed that the percentage of bivalent and trivalent iron oxide in asphalt and concrete pavement increase the bending and pressure strength. Furthermore, Los Angeles experiment shows that the addition of iron oxide crisps the behavior of the covers. In other words, the more metal oxides are added, the more crisp the asphalt and concrete pavement will be.
