PERFORMANCE OF CONCRETE PAVEMENT WITH ECONOCRETE BASE. PROCEEDINGS, 4TH INTERNATIONAL CONFERENCE ON CONCRETE PAVEMENT DESIGN AND REHABILITATION, PURDUE UNIVERSITY, APRIL 18-20, 1989

A three-lane, 16 mile section of I-85 in Randolph and Davidson Counties, North Carolina, was opened to traffic in 1984. The spring following the opening of this section of highway, reddish-brown stains were visible on the concrete shoulders. Water was determined to be flowing under the slabs and blowing out through weak points along the joints. The data collected in an attempt to understand this phenomenon included: horizontal and vertical movements of the slabs, static and dynamic pavement deflections, temperature gradients of the pavement system, location of dowels in the slabs, concrete and soil material properties, and field observations to identify water movement. Possible causes of the problems were identified and methods to minimize damage to the pavement were recommended as a result of this study.
