The use of Titanium Dioxide (TiO2) in the form Ultrafine particles as a coating for concrete pavement have received considerable attention recent years these can trap anti compose organic and inorganic air pollutant by photocatalytic process. In spite promising benefits, durability resistance to wear coatings has not been evaluated. objective this study is determine effect on with spectrophotom...

Steel slags are the major byproduct from the conversion of iron to steel in the basic oxygen (major type), electric arc and open hearth (minor type) steelmaking processes. Steel recovery from the slag results in a processed aggregate with both positive (wear resistant, skid resistant, rough textured, angular, well graded, stripping resistant) and negative (heavy, expansive) features. Considerab...

In this study, nanoindentation was conducted to extract the load-displacement behaviour and the nanomechanical properties of asphalt concrete across the mastic, matrix, and aggregate phases. Further, the performance of hydrated lime as an additive was assessed across the three phases. The hydrated lime containing samples have greater resistance to deformation in the mastic and matrix phases, in...

Abstract Self-healing on pavement is solution to reduce the handling of road damage without doing heavy construction. Calcium Alginate capsules are mixed in AC-WC (Asphalt Concrete Waring Coarse) Asb Lawele as an added ingredient healing from cracks. Marshall Test specification reference assess can use Asphalt Concrete. Optimum Content 6.2% used make Modification Mix with Alginate. contains 2% ...

Asphalt concrete is widely known to be a self-healing material, by repeated loading the micro-cracks have appearing and disappeared when both faces of fissure touch. This process applied until crack completely gone material regains its prior resistance. In this study, two strategies are presented boost healing rate in porous asphalt, one them induction heating. method used mixing 1.1% steel woo...

In this study, stiffness modulus parameters of asphalt concrete were determined experimentally for different temperature and exposure times. The stiffness modules were calculated according to Nijboer stiffness module. Basic physical properties and the quantity of bitumen of asphalt core samples were designated for determining the stiffness modules. The samples were exposed to 17 C (reference te...

The anisotropy refers to the material properties that are direction dependant. In the past, the HMA has been typically modeled as an isotropic material due to a lack of sufficient data for detailed quantification of its direction-dependency. However, it is reasonable to assert that HMA may exhibit significant anisotropic behaviour due to the major compaction direction and the resulting preferre...
