Effect and its Mechanisms of Hydrated Lime on Water Stability of Hot Asphalt Mixture YANG Wenfeng1, a 1 Aviation Engineering Institute, Civil Aviation Flight University of China, Guanghan, P.R.
Introduction Currently, asphalt concretes have been the mostly used highway pavements structure and highway engineering has proposed keen demand for some kinds of asphalt and aggregate [1].
While the fundamental investigation and engineering practice of hydrated lime utilization has been relatively lesser.
Relying on a certain highway construction, the paper has investigated the application of hydrated lime in asphalt mixture from the points of indoor tests, engineering practice and the corresponding mechanism.
