Evaluation of Asphalt Emulsion for Use in Warm Mix Asphalt

Article Preview

Temperature grows up and climate changes year by year as result of global warming. One of the main reasons is the carbon dioxide emission. How to overcome global warming effect by means of energy conservation and carbon reduction is one of the important subjects and one of government's important administrative policies. Nowadays, the price of the international crude oil raised causes the price of the asphalt and ignition oil going up. Warm mix asphalt (WMA), a new-type mix asphalt technology, which has the characteristics of environmental protection, energy conservation and good workability is from Europe. Compared with Hot mix asphalt (HMA), the properties of the WMA is same as the HMA. Thus, the technology of WMA with emulsion asphalt mixture under energy conservation, carbon reduction, and cost reducing by way of temperature control, is introduced by this study in order to change the traditional HMA. The study used dense-graded aggregate with three nominal maximum aggregate sizes (NMAS) of 9.5mm, 12.5mm and 19mm is tested by indirect tensile strength, moisture sensitivity and permanent deformation test for evaluation and the results will be for reference of the HMA mix plant factories.
