Evaluation of Untreated Base Course Material for Drainability

In an effort to prevent pumping and reduce premature pavement failures due to infiltrated water, Utah Department of Transportation (UDOT) has contracted Utah State University (USU) to evaluate the hydraulic conductivity (k) of Utah's dense graded untreated base course material. The hydraulic conductivity describes the ease with which water will flow through the untreated base material. In addition to evaluating the k-value, USU also will introduce possible methods of increasing the flow rate through the base. The analysis will list the hydraulic conductivity of various gradations and their projected costs. This will allow officials at UDOT to choose the most effective untreated base course material with the least associated cost. This research involves looking at present untreated base material specifications and developing new, possible future, specifications to determine the hydraulic conductivity for each specified gradation and then analyzing the costs involved with preparing (i.e. crushing and cleaning) the material needed. It also will be necessary to evaluate if any additional construction costs are involved (i.e. having to use different construction techniques and equipment).
