Precision-engineered machinery manufactured to ISO and international quality standards for demanding paving megaprojects worldwide.
In high-specification asphalt paving—such as airport runways and interstate highways—traditional direct truck-to-paver unloading introduces structural flaws. As Hot Mix Asphalt (HMA) sits in haul truck beds, the outer layer cools rapidly while coarse aggregates shift to the perimeter. Unloading directly into a paver screed results in periodic thermal cold spots and localized aggregate pockets. These segregated zones suffer from under-compaction, leading to premature ravelling, fatigue cracking, and pothole formation within 24 to 36 months of deployment.
A Shuttle Buggy (Material Transfer Vehicle / Paver Feeder) acts as a high-capacity dynamic buffer between the transport fleet and the asphalt paver. By utilizing multi-stage re-mixing augers within an insulated surge hopper, our transfer equipment homogenizes mix temperatures to within ±2°C across the entire mat width, effectively safeguarding structural longevity.
Truck bumps against paver push-rollers create subtle horizontal indentations in the uncompacted asphalt mat. These micro-imperfections significantly degrade the International Roughness Index (IRI). Shuttle buggies decouple the haul truck fleet from the paver. Haul trucks deposit HMA directly into the shuttle buggy’s front receiving hopper without contacting the paver itself.
Operating continuously without stopping eliminates screed settlement marks, improves mat density uniformity, and boosts total daily paving production by 30% to 45%. Contract OEMs and highway engineering concessions achieve substantial bonus incentives linked to target smoothness specifications.
Our advanced paver feeder designs integrate dual-pitch variable flighting augers inside a 25-ton surge hopper. This system continuously cycles material from the perimeter to the center, preserving thermal energy during extended haul times in cold-climate regions or night-paving operations.
Discover the mechanical dynamic innovations, hydraulic drive systems, and smart electronic controls engineered into our high-capacity Shuttle Buggy systems.
Featuring triple-pitch cast chromium-alloy auger flights designed for extreme abrasion resistance. The counter-rotating auger system continuously draws material from all sections of the hopper simultaneously, guaranteeing comprehensive remixing of fine and coarse particles prior to discharge.
Equipped with heavy-duty heat-resistant alloy conveyor chains, insulated transfer tunnels, and optional gas or ceramic infrared heating elements to prevent asphalt buildup during high-stiff-mix applications (such as Stone Matrix Asphalt - SMA or rubberized modified asphalt).
Powered by global Tier 4 Final / EU Stage V diesel power plants coupled with closed-loop electro-hydraulic variable pumps. Intelligent load-sensing controls dynamically adjust engine RPM based on material mass demand, reducing fuel burn by up to 18%.

HEM Group was founded in 1998 by a distinguished group of professors from Chang'an University—China's premier academic institution for highway engineering, pavement dynamics, and construction machinery design. Originally established as Xi'an Hongda Communications Technology Co., Ltd., the company pioneered independent research into high-performance road machinery.
In 2006, the Shaanxi Provincial Department of Science and Technology officially designated HEM Group as a High-tech Enterprise. Our engineering breakthroughs span mechanical dynamics, engine power matching, hydraulic transmission integration, and digital electronic control systems.
To serve global road construction contractors, HME TOP Machinery Equipment Co., Ltd. was established in 2017 as the dedicated export sales arm, facilitating international technology exchanges, global logistics, and round-the-clock technical support.
Operating out of a modern 5,000 m² state-of-the-art production base, our facilities combine automated robotic welding cells, high-precision CNC laser cutting centers, and automated assembly tracks. Every unit undergoes strict non-destructive testing (NDT) of critical frame welds and continuous hydraulic pressure benchmarking before shipment.

Many state transport departments pay contractual smoothness bonuses for pavements exceeding target IRI standards. Achieving high IRI metrics using a Shuttle Buggy frequently repays 40% to 60% of the equipment capital expenditure within the very first highway contract year.
Haul trucks dump material immediately into the Shuttle Buggy receiving hopper without waiting for paver synchronization. Quick unloading reduces cycle times by 10-15 minutes per trip, allowing contractors to operate with 15% to 20% fewer trucks while achieving identical daily tonnages.
By eliminating truck impact against the paver push rollers, structural fatigue on paver tow arms and electronic grade sensors is minimized, cutting annual paver mechanical maintenance costs by up to 25%.
Frequently asked questions by project directors, fleet procurement leads, and highway engineers.
A Shuttle Buggy receives hot mix asphalt from dump trucks and transfers it into an internal surge hopper equipped with variable-pitch re-mixing augers. These augers continuously draw material from the sides and center simultaneously, re-blending coarse and fine aggregates while evening out temperature variations. This ensures a homogeneous mix is fed into the asphalt paver, eliminating cold spots and premature pavement failure.
A standard paver feeder acts primarily as a linear conveyor to move material into the paver hopper. A true Shuttle Buggy incorporates a large surge storage capacity (typically 20-30 tons) and active anti-segregation re-mixing augers inside an insulated hopper. This surge capacity allows non-stop continuous paving even during delays in truck arrivals.
Yes. We engineer our equipment with flexible power engine options. Depending on your region, we offer Tier 3, Tier 4 Final, or EU Stage V compliant diesel engines (Cummins, Deutz, or premium domestic engines), alongside customized hydraulic circuits, hopper sizes, and electrical configurations to match local regulatory standards.
Our augers are cast from high-chromium wear alloys with HRC 58-65 surface hardness, and conveyor floors are lined with Hardox abrasion-resistant steel. Under standard asphalt mix conditions (non-excessive quartz aggregates), liners and augers typically achieve 150,000 to 250,000 tons of throughput before major overhaul.
When haul trucks back up and bump into a paver, they transmit horizontal impact forces that cause small dips in the uncompacted mat under the screed. Furthermore, stopping the paver allows the screed to settle into the hot mix. By transferring material via a non-contact Shuttle Buggy, the paver operates at a constant continuous speed, dramatically lowering IRI values and maximizing pavement smoothness.
We provide comprehensive 24/7 technical support, on-site operator commissioning, and maintenance training. We maintain strategic global spare parts hubs across Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka, allowing rapid delivery of replacement parts to keep your fleet fully operational.
