Sustainable Design of Concrete Bus Pads to Improve Mobility in Baltimore City

Major surface cracks and local failures were observed in concrete bus pads throughout Baltimore City, resulting in major replacement costs for Baltimore City. While concrete slabs are more durable than asphalt, there still exists a lack of appropriate load identification and definition of critical load scenarios for the appropriate design of the concrete bus pads such that major cracking is minimized. As such, the main goal of this research is to formulate a newly proposed design for sustainable concrete bus pads that can withstand various loading scenarios to minimize cracking. Specifically, the research objectives of this study are to: 1) evaluate appropriate design criteria for newly designed bus pads, including assessment from experimental test data from in-situ bus pads (strips) retrieved from the field prior to a replacement job, and 2) experimentally test a newly designed bus pad (strip) with embedded sensors that can be used as a testbed for load detection to optimize movement.
