High Temperature Properties of Asphalt Modified with Two Kinds of OMMTs

Abstract:

Article Preview

In order to improve the rutting resistance of the asphalt pavement, the base asphalt needs to be modified. Two kinds of nano-organic montmorillonite (nano-OMMT) with different interlayer spacing were used as the modifier. The content of the two OMMTs in asphalt is the same, being 3wt%. The high temperature properties of the modified asphalts were compared. The effect of interlayer spacing of nano-OMMT was discussed. Results have shown that different nano-OMMT interlayer spacing leads to different high temperature properties. The asphalt modified by 3wt% of the OMMT with the interlayer spacing of 2.8nm shows better high temperature resistance that modified by the OMMT with the interlayer spacing of 3.8nm. More nano-OMMTs with other interlayer spacings should be used to explore the effect of interlayer spacings on the properties of asphalt.
