A Comparative Experimental Study on the Hydraulic Conductivity of Treated and Untreated Open-Graded Base Courses

Résumé fourni par la source

An experimental program was conducted to determine the coefficient of hydraulic conductivity of both treated and untreated open-graded base samples made from four different gradations, three aggregate types and two binder types. For the same gradation, dolomite samples have the highest K value, followed by natural gravel and recycled concrete aggregate respectively. Treated open-graded samples have K values in excess of an order of magnitude while the difference in K value between the asphalt-treated open-grade samples was less than an order magnitude
