DOWNLOAD EBOOK →Due to an increase in demand to shorten construction time as much as possible, the purpose of this project was to determine the optimum strength for concrete pavement before opening it to traffic and without jeopardizing long-term performance. Six test cells in MnDOT’s MnROAD project were constructed in 2017 with varying degrees of early loading. Various tests were performed during and immediately following construction and, four years later, ride quality and load transfer efficiency were used to quantify long-term damage. A finite element analysis was then performed using ISLAB2000 to determine the effects of load location and temperature gradient on the Portland cement concrete (PCC) longitudinal stresses to explain the absence of premature failure. A mechanistic-based early opening damage analysis procedure was created to determine the optimum timing for opening of a concrete pavement to traffic. The procedure accounts for the effect of site conditions and pavement characteristics. A web-based tool was developed to facilitate implementation of this procedure.

DOWNLOAD EBOOK →This report discusses the accomplishments of the Center for Portland Cement Concrete Pavement Technology (PCC Center) at Iowa State University, which was founded in April 2000. The report discusses the advisory groups that guide the Center, and describes the facilities included in the Center. The two Center facilities are the PCC Pavement and Materials Research Laboratory and the Mobile Concrete Research Lab. The report details the combined test capability of the Center's two labs, and describes the research undertaken at the Center. Also included in the publication are long-term planning efforts and technology transfer studies.
