Macomb Correctional Facility – Pavement Rehabilitation Project

Pavement engineering

The Macomb County Correctional Facility rehabilitated its pavement to improve parking lots and walking paths.

New Haven, Michigan

When the Macomb County Correctional Facility required new driveways, roadways, sidewalks, a walking track, and basketball courts, G2 Consulting Group acquired the necessary background clearances for staff and provided geotechnical investigation services, and special inspections / materials testing services within the correctional facility.

Fast Facts

Project Scope
G2 performed a geotechnical investigation for earthwork operations, foundation design, and construction considerations and performed special inspections and materials testing services during construction.

G2 professionals explored the site during the geotechnical investigation for a complete pavement repair program. This included pavement recommendations and construction considerations related to roadway and driveway access and service equipment.

Within the correctional facility, G2 performed special inspections / materials testing scope of services that included evaluating earthwork operations, utility installation, flatwork, and site concrete, and bituminous paving.

G2 Consulting Group evaluated the existing conditions and provided solutions that allowed for work within a highly regulated correctional facility. The pavement repair strategy needed to work around the confines of correctional facility rules and regulations and also work within an expedited timeline. G2 worked with Anderson, Eckstein, and Westrick, LLC, to create a removal pl

an that allowed for efficient, expedited removal of materials without disrupting the operations of the correctional facility. 

Smart. Results. Fast.

G2 Consulting Group provided cost-effective solutions to keep the project moving forward during a tight construction schedule.

G2 Consulting Group understands the growing importance of renewable energy in the United States and it has positioned itself to be a key player in the power and energy sector by providing geotechnical services to companies who design and construct solar sites. Typically, these projects run on very tight timelines and cover multiple states. For example, during a tight two-month period (November 2, 2018 – January 3, 2019), G2 provided geotechnical services for 12 solar power plant sites in six states (Colorado, Florida, Georgia, Illinois, Texas, and Virginia).

Superpave Gyratory Compactor expands Hot Mix Asphalt testing capabilities

James Berry, P.E. Project Manager

G2 Consulting Group is expanding its Hot-Mix-Asphalt (HMA) testing capabilities at its Troy laboratory with the addition of a new Superpave Gyratory Compactor (SGC).  The new machine is a Model AFG2 manufactured by Pine Test Equipment, Inc. The SGC will allow G2 Consulting to test and determine the volumetric properties of the newer Superpave HMA mixtures (MDOT E series mixes) that are being used more and more by our local and regional agency clients.

What is Superpave?

Superpave stands for Superior Performing Asphalt Pavements. It is a mixed-design method that makes the best use of asphalt paving technology and enhances asphalt pavements’ ability to balance the high-temperature rutting and low-temperature cracking characteristics of asphalt concrete. Superpave replaces the Hveem and Marshall methods.

Why is it important?

Harvey Hurwitz, Senior Engineering Technician demonstrates compaction sampling.

Determining volumetric properties of compacted HMA samples is an important component of mix design development and project quality control and quality assurance testing. With the older Marshall designed mixes, this was relatively easy with simple mechanical compaction equipment. Superpave mixes require the much more sophisticated SGC to compact the laboratory samples for testing. The SGC allows us to produce samples in our laboratory representing a variety of different projected traffic loadings using compaction methods that more closely simulate mix compaction under repeated vehicle wheel passes rather than compaction with a smooth drum roller. Many regional agencies are requiring volumetric properties tests as part of standard QA/QC testing, and it is anticipated that MDOT Local Agency Projects will require QA volumetric testing for Marshall and Superpave HMA mixtures in the near future.
