Superpave Gyratory Compactor expands Hot Mix Asphalt testing capabilities

G2 Project Manager James Berry

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.

Transformers: Dominick’s Grocery to Emagine Theatre

 

You know it as a movie, but G2 Consulting Group became “Transformers” when it helped convert a former Dominick’s Grocery Store into a 10-screen Emagine Theatre – the first in the state of Illinois. The fast-tracked project consisted of a 70,000 square foot slab-on-grade building that required the removal of portions of floor slab and grade cuts of up to 10 feet to construct the individual theaters. Building columns were relocated as needed and the roof beams were reinforced to carry additional loads.

Fast Facts

Project Owner
Emagine Theatre

Project Scope
G2 Consulting Group worked collaboratively with Tower Construction (GC) during all phases of the project to construct the first Emagine Theatre in Illinois.

Services Provided
Geotechnical Investigation
Environmental Engineering Services (Phase I, Asbestos Survey)
Quality Assurance / Materials Testing / Steel Inspection
Clean Construction or Demolition Debris (CCDD) Services

Challenges / Solutions
G2 Consulting Group found that existing fill soils were present below the floor slab and allowed for new foundations to wear on existing soils provided they were observed and properly documented during construction.

The project moved at a very fast pace and G2 was available to cover inspections on short notice – sometimes within two hours of being called. This allowed the project to move forward without delays.

How did we accomplish “Smart. Results. Fast”?

Soil borings within the interior of existing buildings can be challenging due to height and width restrictions of drilling equipment. G2 used its contacts with local drillers to determine the best equipment to allow for access and drilling within the building and work was completed in two days. G2 also coordinated environmental surveys at the same time as drilling to minimize delays to the project and minimize interruptions to the building.

G2 fast-tracked CCDD testing on short notice to allow for offsite disposal of soils and allow the contractor to stay on schedule with soil removal. There was no place to stockpile soils and any delays with soil removal would have hindered the project timeline.

New FedEx Facility @ Former Detroit Artillery Armory

Chris Nicol, PE/Project Manager

Chris Nicol, P.E.
Project Manager

FedEx Corporation will occupy a 300,000 square foot distribution center currently under construction on the former site of the Detroit Artillery Armory in Oak Park, Michigan. The property had included a 494,000-square-foot building that was a machine gun manufacturing plant during World War II, which has been demolished. The property then was turned over to the Michigan National Guard after the war for training and storage until the early 1990s, and then just for storage until 2000.

G2 Consulting Group was retained by Giffels Webster to perform a geotechnical investigation on the 60 acre site, which had varying depths of fill remaining from former uses. G2 characterized subsurface materials and developed deep and shallow foundation designs for consideration. After reviewing options, Scannell Properties, the construction developer, decided to remove and replace existing fill and construct shallow foundations. G2 now is working with Scannell Properties to perform QC during construction for earthwork, foundations, pavements, floor slabs and structural steel.

Waterford Mott High School Expansion

Waterford, Michigan

 

Waterford School District added 55,000 square feet to Waterford Mott High School, including a new gymnasium and auditorium. Unsuitable soils made construction of conventional shallow foundations difficult. G2 Consulting Group reviewed a number of alternatives to identify the best approach. G2 assisted during construction to confirm that design intent was followed in the field.

Fast Facts

Project Owner

Waterford School District

Scope

Prior to construction, G2 performed a geotechnical investigation including soil borings and test pits to define soil and groundwater conditions and developed recommendations for foundation design and construction. During construction, G2 performed all QC/QA testing, including auger-cast pile installation and static load testing.

G2 Services Provided

Geotechnical Investigation

Materials Testing and Special Inspections

Challenges/Solutions

      • Unsuitable soil conditions consisting of fill and organic matter were found on site to depths of up to nine feet. G2 considered several foundation alternatives to address variable soil conditions and recommended extending strip and spread footings through the unsuitable material, widening existing foundations to support the adjacent loads, and using a tangent force auger cast retaining/foundation system.
      • When the construction team was in the process of removing unsuitable soils near existing foundations to accommodate widening, the team realized that organic matter extended below the existing foundations as well. G2 quickly evaluated the situation on site and designed and installed an auger cast pile foundation in one day.
      • G2 observed construction operations and performed tests during all phases of construction to verify design intent: earthwork operations; auger cast pile installation and subsequent load tests, excavation and backfill of utilities and foundations, concrete placement for foundations and floor slabs, construction of an MSE wall in the auditorium area, grout and mortar testing for masonry construction, steel erection and pavement construction.

Smart. Results. Fast. Soil conditions were less than ideal for the planned construction. G2 developed a cost effective multi-faceted approach and offered real time response to unexpected conditions, maintaining the construction schedule.
