This report describes the development of a complete pavement system which incorporates an open graded drainage layer to effectively remove infiltrated water. Candidate materials for use as open graded drainage layers were investigated using laboratory studies of flow characteristics and loading studies to measure accumulated deformations. The research team found that the required hydraulic conductivity of an open graded drainage layer must exceed 1,000 fpd for typical interstate design. For extreme conditions, hydraulic conductivity requirements may approach 5,000 fpd. Two standard Illinois DOT aggregate gradations, CA-7 and CA-11, were found to have hydraulic conductivities in excess of 5,000 fpd. Stability tests conducted on the open graded drainage layers indicate that stabilization with PCC cement or asphalt cement would be required if the materials were to be trafficked prior to final paving. Minimum PCC cement contents of 6% by weight of aggregate are required for adequate stabilization. Minimum asphalt cement contents of 2.5% are required. Observations of open graded drainage layer construction projects were made to document the practicality of construction. These observations indicate open graded drainage layers may be successfully placed if construction equipment specially suited to these materials is used.

Familiarity with geotechnical aspects of pavement engineering is essential for the practicing pavement engineer. When designing pavements, accurate characterization of the existing subgrade condition becomes a crucial task. In the past, traditional geotechnical exploration and testing methods have been used to characterize existing subgrade conditions. However, with the introduction of the Mechanistic-Empirical (ME) pavement design, there is a need for improved and more appropriate methods of subgrade characterization, for prediction of future pavement conditions with better accuracy. Hence, this handbook will present a useful tool for practicing pavement engineers.
