Application of Diatomite Modified Asphalt

Article Preview

Abstract:

The present domestic modifiers are mainly by-products of petroleum --- costing high and non-renewable, which lead to the difficulty in their wide use. This paper explores the mechanisms of purified diatomite, enhancing the stability of asphalt mixture under high temperature, low temperature or with water. At the same time, the paper makes analysis on the economy of project application, providing theoretical and economical references for spreading purified diatomite as a new modifier.
