TONOPAH, NV - FULL DEPTH RECLAMATION PROJECT
Tonopah Test Range, A.K.A. Area 52, located 30 miles southeast of Tonopah, Nevada, is currently used for weapons stockpile reliability testing, research and development, owned by the United States Department of Energy and administered by Sandia National Laboratories, a division Lockheed-Martin, since 1957.
With its aging roadway infrastructure, including service and vital connecting roadways subjected to heavy military use and extreme climate changes at an elevation of 5,550 ft, engineers seek sustainable designs that meet the facility expectations.
With the facility’s remote topography and limited resources, the method of rehabilitating roadways can be an economical and constructability challenge. One sustainable method the design engineers utilized in 2010, was the method of Full Depth Reclamation (FDR). Utilizing the roadways existing materials minimizes the need for outside resources, while reducing costly expenses and energy demands associated with typical roadway reconstruction. FDR is the method of pulverizing the existing asphalt concrete and underlying materials, treated with cement, and constructing a new hot mix asphalt concrete wearing surface.
Since 2010 Pavement Recycling Systems, known for their large scale FDR capabilities, has contracted with Labelle-Marvin, Inc., to provide the on-going quality control services; including our materials testing and on-site construction inspection services at the Tonopah Test Range facility.

LACMA - LEVITATED MASS "THE ROCK"
The Levitated Mass, a.k.a. “The Rock”, weighing approximately 340-tons, has resided at the Los Angeles County Museum of Art (LACMA) for public viewing since mid 2012. How it travelled from Northeast Riverside County to LACMA near downtown Los Angeles may have been lost in the shuffle, but has not been forgotten by those involved in the transport process. The move represents a magnificent victory for the engineers who made it possible to travel the distance with minimal impact to the city infrastructure, pavements, traffic lights, power lines, and bridges.
One thing that may have gone unnoticed to the general public was the impact below the surface. The pavement was initially designed to support the City’s typical traffic use of automobiles, buses and trucks. A large oversized suspended granite rock cradled by a large metal sling with multiple tires and hydraulic steering to negotiate the city streets pounding the pavement traveling at a grueling 8 mph or less was something the original designers could not have foreseen.
Prior to its final journey, LaBelle Marvin, Inc. (LMI) measured the pavements in-place strength through various City’s streets and thoroughfares. Assessing the risk of catastrophic failure was not only important to the transportation of the equipment involved, it was critical in selecting the haul route. Re-routing the rock, ultimately delaying the rock arrival to the museum was a possibility however the city roadway strengths had to be verified to avoid damage and associated costly repairs. Precise field measurements combined with estimated wheel loading and associated variables minimized the potential for burdensome roadway reinforcement after the rock was placed in the final resting exhibit.
LMI provided pavement strength (Falling Weight Deflectometer) testing along the proposed haul route to determine the current load carrying capacity of the existing roadway and to extrapolate the projected fatigue resistance for the subjected roadway segments. The testing sequence was crucial to assess the existing or current roadway strength and to minimize the impact of the haul operations. The evaluation process determined where the pavement was capable of supporting such a large mass transport and defines where possible additional reinforcement through use of steel plating or similar precautions was required.
LMI has provided these types of pre-hauling roadway impact studies during heavy equipment hauls for similar projects including but not limited to the Space Shuttle Facilities at Vandenberg AFB, and public roadways relating to electrical transformer transport, railroad rolling stock relocation, large scale land fill operations, and oil industry equipment moves. LMI is currently performing pavement strength studies before and after each sequence of decommissioned electrical generator haul operations between the Edison Power Plant at San Onofre California and the long term storage facility in Utah. LMI welcomes the opportunity to apply our prior experience to your next scheduled move. Please contact our office for more information.

SAN ONOFRE NUCLEAR POWER PLANT
The San Onofre Nuclear power plant, located near the City of San Clemente, California and operated by Southern California Edison, has been in operation since 1968. Within the last year (2011) the plant has been moving four separate, 380-ton sections, of its retired steam generator to a long term storage facility in Utah, transported by a 192 wheeled vehicle. The transport vehicle has been engineered with high tech computer controlled steering which is strategically positioned over its massive 400-feet in length and measuring approximately17 feet in height. The length alone is astonishing to navigate safely throughout city and state roadways but meticulously maneuver its enormous weight over an estimated 21 day trip at a top speed of 25 mph is a tactical engineering feat in itself.
As with our numerous past structural investigations involving the measurement of critical impacts subjected to city roadways from massive hauling activities, LaBelle Marvin, Inc., currently provides the meticulous approach of performing a pre-run of this route by measuring the pavements potential supportive conditions before and after each move. Catastrophic failure is initially determined by our study, from evaluating the pavements potential distress prior to the transport, then analyzed by our technical staff to evaluate it long-term effects on each segments pavement life.
LMI has provided these types of pre-hauling roadway impact studies during heavy equipment hauls for similar projects including but not limited to the Space Shuttle Facilities at Vandenberg AFB, and public roadways relating to electrical transformer transport, railroad rolling stock relocation, large scale land fill operations, and oil industry equipment moves.
