QES' responsibilities for the SR 125 San Diego Gap/Connector & Toll Road project were to provide a new, rigid pavement design on asphalt base course and to develop an innovative, full depth asphalt pavement section for the toll road portion of the project. A specific challenge was to design an asphalt pavement for heavy traffic loading to meet a tight existing budget. QES worked with the prime consultant to develop specifications and mixes, using on-site and locally available aggregates.
