New Alaska Database Aids Treatment Selection By Steve Saboundjian, P.E., and Angela Parsons, P.E. A laska’s new web-based pavement preservation treatment database provides an online treatment strategy selection program to support Alaska’s asphalt pavement preservation program. The recently enacted MAP-21 surface transportation legislation strongly emphasizes the concepts of asset management and preservation. The law contains language that is helpful to pavement preservation (PP) and is expected to bring great benefits to owner agencies, the preservation industry, and road users. The promulgation of this law almost coincided with the completion of a PP study for Alaska in fall 2012. In its continuing efforts to enhance its preventive maintenance program, the Alaska Department of Transportation & Public Facilities (ADOT&PF) has collaborated with the California Pavement Preservation Center and the Alaska University Transportation Center to complete a PP research project titled Developing Guidelines for Pavement Preservation Treatments and Building a Pavement Preservation Program Platform for Alaska. The main product of this effort was the development of a web-based PP treatment database with an online treatment strategy selection program to support Alaska’s asphalt PP program. TRACKING FIELD TRIALS For many agencies, it has always been a challenge to keep track of field trials and performance of new PP methods. Field trials seldom are properly documented or shared with other entities and agencies. To enhance management of PP innovations and promote effective techniques, the research team developed a treatment database which will keep track of the performance of innovative projects and promote the use of effective PP techniques. This tool, located at http://ceresearch.ecst.csuchico. edu/cp2c/AlaskaPPDB/, has long-term value in helping ADOT&PF and local agencies obtain PP performance information, such as multiple year condition survey results, expected life, and life-cycle cost from the project data. More specifically, the purpose of the database is to: • Centralize and archive important preservation project information in a database residing on a secured server • Monitor PP innovation projects/treatments including interactive web mapping to display project locations (through Google Map embedded in the application) • Enhance collaboration and technical information transfer by using an online system to share information on PP activities amongst Alaskan entities, and • Develop a pavement treatment selection program based on the information in the database, such as pavement condition, traffic, environmental conditions, life-cycle cost or cost-effectiveness. The database can be accessed by three user levels: general users, advanced users, and database administrator. To promote knowledge sharing amongst agencies and industry, anyone Summer 2013 pavement preservation journal 27 PARTNERSHIPS ADOT&PF BY IVAR ENGEL Pneumatic (rubber-tired) roller compacts chip seal http://ceresearch.ecst.csuchico.edu/cp2c/AlaskaPPDB/ http://www.naylornetwork.com/FPP-nxt/
