The developer must submit a Final Pavement and Geotechnical Report for the project to the Office of Materials Technology. The report shall contain the Developer’s plans for addressing all soils, rock, groundwater, existing pavement, and new pavement issues on the project impacting Maryland Department of Transportation State Highway Administration (MDOT SHA) highway property. A geotechnical engineer, who is a registered professional engineer, and who shall also seal the Final Pavement and Geotechnical Report, will supervise the work.
The developer shall obtain all soils and pavement information necessary to properly complete the Final Pavement and Geotechnical Report, and the design and construction of the project. The Developer shall perform borings, sampling, in-situ and laboratory testing, analysis, and design required for this purpose. All subsurface investigations, including sampling and laboratory testing, must be performed in accordance with MDOT SHA Standard Specifications for Subsurface Explorations. If a specialized test is not covered by these specifications, then testing shall be performed in accordance with the latest AASHTO Manual on Subsurface Investigations, AASHTO Standards and ASTM Standards.
The existing structural capacity of all impacted shall be determined through infield non-destructive testing either a formal visual condition survey or deflection testing and/or pavement borings.
Laboratory testing shall be performed in an AMRL or MDOT SHA certified laboratory.
The recommendations contained in the Final Pavement and Geotechnical Report shall be incorporated into the plans and specifications developed for the project. The Developer shall be responsible for utility clearance and any traffic control required for his investigation. The appropriate district office must approve the Developer’s Maintenance of Traffic Plan for the subsurface and pavement investigation.
Any investigative methods that pose a hazard to the general traveling public shall not be used. Any borings taken in roadway or shoulder areas shall be backfilled in kind with material before the area is re-opened to traffic.
