An attempt was made to develop a sustainable Transportation Infrastructure Management System TIMS) for a typical college campus and/or any low volume road network. First,a sustainable Pavement Management System PMS) was developed using different Maintenance and Rehabilitation M&R) techniques. MicroPAVERTM) PMS software was utilized to analyze the present condition and to predict the future condition of pavement for the University of Rhode Island URI) Kingston campus. Economic analysis was performed using the default rates of MicroPAVERTM) for different M&R policies and compared with the ones used in one of typical municipalities,i.e.,The City of Cranston,Rhode Island RI). Secondly,model input parameters were formulated for the American Association of State Highway and Transportation Officials AASHTO) Mechanistic-Empirical Pavement Design Guide MEPDG) to use in RI,because having a strong initial pavement is essential for sustainable PMS. Superpave specifications were used to generate material parameters to design the Upper College Road as a model pavement structure. Then energy efficient and environment friendly M&R strategies were explored to introduce into the developed PMS,i.e.,Cold In-Place Recycling CIR) and Warm Mix Asphalt WMA). A series of tests were conducted to predict their performances,e.g.,thermal cracking,fatigue cracking and permanent deformation or rutting. Finally,a Geographic Information System GIS) was used as a tool for automated drafting and data storage. Maps generated with different color coding will assist decision makers quicker and better interpretation. The results of the present study can be used for any pavement networks particularly with low traffic volumes,e.g.,cities and towns,and also have a reasonable potential to be used by any other larger agencies,e.g.,State Department of Transportation DOT).
