PREDICTING THE EFFECT OF ADDING THE NANOALUMINA ON THE CHARACTERIZATION OF ASPHALT BASE COMPOSITE

Current paper has studied the causes of pavements flexibility besides various alternatives to solve the problems failure, for example: fatigue ,rutting, cracking of low temperature which are because of the sensitivity of the temperature and the susceptibility of the moisture and of either the mixture of the asphalt or asphalt/aggregate entirely. This study is designed to identify applicability that is potential and the best amount of Nanoalumina in asphalt in addition to the mixtures of the asphalt concrete. Most asphalt consists of nitrogen carbon, oxygen, sulfur, and hydrogen. At low loading or temperature that is high, asphalt acts as a liquid that is viscous which due to dichotomy that is classical. The paper aims to modify the quality of bitumen materials by increasing the durability. Five percentage of nanoalumina (0.5%, 1%, 1.5%, 2%, and 2.5%) (w/w) was added to pure asphalt. According to Marshall Test Nanoalumina modified the samples. Experimental tests have shown an improvement in physical and properties that are mechanical of mixtures of asphalt after adding Nanoalumina. As a result Nanoalumina has the ability to modify asphalt by reducing penetration and increasing kinematic viscosity.
