Learn About Full-Depth Reclamation of Pavement with Lindsi Hammond

Full-Depth Reclamation of Pavement

Full-depth reclamation (FDR) of pavement is an alternative rehabilitation technique that uniformly pulverizes and blends together stabilizing agents with worn-out asphalt concrete pavement and a portion of the underlying materials.  The end result is a sustainable, cost-effective, and green approach to stabilized base course that is ready for a new pavement surface.  Successful FDR projects improve the structural capacity of the pavement and are developed through pre-construction engineering and design.

Presented by Lindsi Hammond, PE

Lindsi will be speaking at the ACEC/ODOT Region 1 Brownbag this Wednesday, May 25th at noon.  Lindsi joined GRI’s Beaverton office in August 2015 and has more than nine years of pavement engineering experience.  Her project work includes pavement management, pavement evaluation, and pavement design.  As a project engineer, she is responsible for completing the implementation and update of pavement management systems for airport and roadway systems, backcalulating falling weight deflectometer (FWD) data, and designing pavements using the AASHTO, Asphalt Institute, FAARFIELD, PerRoads, PCASE, and Portland Cement Association methods.

Mike Marshall is Taking Geologic Reconnaissance to New Heights

Mike recently completed a 5-day rope access course in Bend, Oregon.  Rope access refers to a set of techniques where ropes and specialized hardware are used as the primary means of providing access to GRI engineering geologists for geologic mapping.  His 5-day course prepared him for successful completion of a written exam and field evaluation for Society of Professional Rope Access Technicians (SPRAT) Level I certification.  GRI’s rope access technicians descend, ascend, and traverse ropes for access to shear rock faces to work while suspended by a harness. Mike now has the training and certification to safely and effectively access hard to reach geological features for close examination.

Mike Marshall, CEG, to Present at the AEG Annual Meeting

Mike will be giving a presentation on the geologic characterization and landslide hazard assessment of the Oregon Coast Range transmission line. If you are attending the meeting, this presentation will be a part of Technical Session #7 this Thursday at 8:40am. Below is a synopsis of the presentation:

 

Geologic Route Characterization and Landslide Hazard Assessment of
Oregon Coast Range Power Transmission Line

bpa-photo-lidar-msmThe Bonneville Power Administration (BPA) elected to replace an aging 115-kV power transmission line in the Oregon Coast Range, which is a belt of uplifted sedimentary and volcanic rocks near the Pacific Ocean. A geologic route characterization and landslide hazard assessment was conducted to characterize and map landslides and identify areas of potential slope instability that could damage transmission structures. The type and occurrence of landslides was evaluated using information gathered through review of geologic maps and literature, aerial photography, Statewide Landslide Database for Oregon (SLIDO), and lidar data. Landslides identified from literature and remotely sensed data were cataloged in GIS and a surface reconnaissance was conducted by GRI. A total of 76 structures were located in areas identified as landslide topography. Ground cracks indicative of slope movement were observed at nine structures and four locations were identified with loose guy wires during the surface reconnaissance. Each of the 331 structures assessed were assigned a hazard rating based on documented or observed landslide features, indications of recent mass movement, and/or observed ground cracks. Structures were rated from high to low risk for the prioritization of mitigation efforts. Of the 331 structures assessed, 12 structures were identified as having a high risk for future slope instability. All but three of the high-risk structures appeared to be associated with sidecast fill placed as part of access road and structure work pad construction. In general, the slope instability associated with the roads and bench areas appeared to be the result of oversteepened, loose sidecast fill placed on steep natural slopes or steep cut slopes.

George Freitag, CEG, to Present at the 2016 AEG Annual Meeting

George will be giving a presentation on the engineering geology of the Meyers Cone along Interstate 84. If you are attending the meeting, this presentation will be a part of Technical Session #17 this Friday at 9:40 am. Below is a synopsis of the presentation:

 

Engineering Geology of the Meyers Cone,
Interstate 84, Columbia River Gorge, Oregon

Lidar and new geologic data have revealed a previously unmapped Quaternary volcanic vent system near MP 49 along Interstate-84 (I-84) in Hood River County, Oregon.  We refer to the feature as the Meyers Cone, which is a 650-ft-high olivine basalt edifice with two prominent flow lobes, the Anderson Point and Trotter Point lobes that extend under I-84 into the Bonneville Pool.  Features including a 25-ft-high, 1,200-ft-long volcanic flow are preserved on the inside of the cone.  A northeast-southwest trending rampart system is present on the west side of the cone and goes toward other newly identified vents to the southwest.  Eruptions on the east side of the cone deposited on a pre-existing, north-sloping, alluvial fan complex. A band of east-west oriented tension features (scarps) on the upper portion of the fan are interpreted to be the result of destabilization of the fan by deposition of material near the fan toe.  The historic Fountain Landslide along I-84, east of the Meyers Cone, is located near the toe of the fan.  Previous workers interpreted the subject area solely as a distal portion of the Trout Creek Hill basalt (385 Ka) that flowed down the Wind River drainage from Washington and temporarily blocked the Columbia River. Beginning with railroad construction in the 1880s, the Historic Columbia River Highway in 1914-15, US-30 in the 1950s, and I-80N/I-84 in the 1960s, the geology of these transportation routes has been influenced by the Meyers Cone.  We propose that the cone should be officially named after Joseph Meyers, the Oregon geologist who first identified some of the flow features in the 1950s.
