Lime-Fly Ash-Aggregate Base and Subbase Courses
This paper describes the use of lime-fly ash-aggregate (LFA) base and subbase courses for highway pavements. This type pavement course is considered as an alternate to cement treated bases...
Theoretical Prediction of Temperature Distributions in Airfield Runway Pavements Due to Aircraft Operation
The determination of this transient temperature distribution is important in predicting the thermal effects on pavements due to aircraft operation. In this research, heat exchange at the...
