Introduction: Precision on the Tarmac
Airport runway reconstruction demands more than just asphalt and machinery—it requires precision, timing, and consistency. At Meeker Airport in Colorado, a critical general aviation hub, the reconstruction of Runway 3-21 showcased how Material Transfer Vehicles (MTVs) can elevate paving quality and efficiency. This article explores the technical role of MTVs, their impact on project outcomes, and the broader implications for airport infrastructure.
Key Terminology Explained
United Companies, the contractor, acquired their Shuttle Buggy from a sister firm and became the only contractor in western Colorado with an MTV. This gave them a strategic advantage, especially as federal specifications increasingly required MTV use for quality assurance.
Historical Context: MTVs in Airport Paving
MTVs emerged in the 1990s as a solution to common paving issues like truck bumping and material segregation. Their adoption in airport projects grew as FAA standards tightened, demanding smoother, more durable surfaces. The Meeker Airport project exemplifies this evolution, where technology met regulatory rigor.
Best Practices for MTV Use
The final IRI of the Meeker runway was well within FAA specifications. The paving crew credited the MTV with helping achieve this result, noting that the smoothness of the finished surface was evident even without measurement tools.
Conclusion: Paving the Way Forward
Material Transfer Vehicles are more than just a convenience—they’re a cornerstone of modern airport paving. By ensuring continuous flow, remixing asphalt, and maintaining temperature consistency, MTVs help contractors meet the exacting standards of aviation infrastructure. As federal agencies increasingly mandate their use, the Shuttle Buggy and its peers are becoming essential tools in the quest for smoother, safer runways.

Key Terminology Explained
- Material Transfer Vehicle (MTV): A machine that stores and remixes hot mix asphalt (HMA) before delivering it to the paver, ensuring temperature consistency and reducing segregation.
- Shuttle Buggy®: A specific MTV model known for its patented anti-segregation auger and large storage capacity.
- FAA-Spec HMA: Asphalt mix formulated to meet Federal Aviation Administration standards for airport pavements.
- Straightedge Tolerance: A measurement standard requiring the finished surface to deviate no more than 3/16 inch over 16 feet.
- International Roughness Index (IRI): A metric used to evaluate the smoothness of pavement surfaces.
- Runway widened from 60 to 100 feet, maintaining a length of 6,500 feet.
- Apron and taxiway construction added significant surface area.
- Over 100,000 cubic yards of dirt moved and 70,000 tons of crushed aggregate base placed.
- 23,000 tons of FAA-spec HMA laid in two 2-inch lifts.
- Storage and Flow Management
The Shuttle Buggy stored up to 15 tons of asphalt, allowing trucks to unload immediately and reducing wait times.
- Remixing Capability
Its triple-pitch auger remixed asphalt to eliminate temperature and aggregate segregation, ensuring uniform compaction.
- Temperature Control
Infrared imaging showed temperature differentials below the critical 7°C threshold, a key factor in pavement durability.
- Reduced Rework
Minimal grinding was needed post-paving, attributed to the consistent flow and remixing provided by the MTV.

Best Practices for MTV Use
- Position MTV Close to Paver
Ensures minimal delay and consistent material delivery.
- Monitor Temperature with Infrared Imaging
Helps verify remixing effectiveness and compaction readiness.
- Use Experienced Crews
Operators familiar with MTVs can better manage flow and detect issues early.
- Coordinate with Asphalt Plant
Even short transport distances can affect mix quality; MTVs mitigate this risk.
- Document Performance Metrics
Track IRI scores and temperature differentials to validate quality outcomes.
