In recent years there is a change in atmospheric condition. One of the major reason behind this change is air pollution which is increasing day by day. Air pollution is mainly due to rapid industrialization and increases in a vehicular transportation system. The major components of air pollution such as SOx , NOx, CO, and many other gases are released due to the combustion of a vehicle engine. In developing country like India, roadways play a key role in the transportation system. Hence to curb the effect of this transportation system on our ecosystem new ways of elimination of this pollutants shall find out. Hence an attempt is made in this research to construct the pollution absorbing pavements i.e. to construct such pavements which will absorb these harmful pavements. The main aim of this research is to investigate the elimination of NOx i.e. Nitrogen Oxides by casting pavements of Cement, Flyash, Recycled Glass and Photocatalyst such as TiO2, i.e. Titanium Dioxide or Titanium (IV) oxide under varied conditions
