Explore our high-performance fleet designed for deep pulverization, asphalt milling, cold recycling, and precision binder distribution.
Pioneering China's Cold In-Place Recycling (CIPR) & Full Depth Reclamation (FDR) Equipment since 1998.
HEM Group was founded in 1998 by distinguished professors from Chang'an University—China's premier academic institute for highway engineering—and veteran road construction machinery specialists. Originally established as Xi'an Hongda Communications Technology Co., Ltd., we stand as one of China's earliest high-tech pioneers devoted to independent research, dynamic modeling, and mechanical design of advanced road construction equipment.
Driven by high-tech R&D, our engineering innovations span mechanical dynamics, diesel engine power matching, high-pressure hydraulic transmission systems, and digital electronic metering control. Officially recognized as a "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, HEM Group expanded its global commercial arm in 2017 via HME TOP Machinery Equipment Co., Ltd. to provide worldwide sales, OEM customization, and technical field services.
A comprehensive whitepaper overview on transforming deteriorated asphalt pavements into durable, high-load bearing structural bases using modern Cold In-Place Recycling (CIPR).
Our FDR machinery utilizes heavy-duty tungsten-carbide cutter rotors capable of milling and pulverizing asphalt bound layers and underlying granular bases to depths up to 500 mm in a single pass.
Precision liquid binding injection is critical to structural longevity. HEM's advanced injection manifolds dynamically spray calculated dosages based on travel speed and material mass flow.
Combining mechanical stabilization with hydraulic binders like Portland Cement or hydrated lime dramatically boosts structural layer coefficients (Resilient Modulus M_r > 3,000 MPa).
| Engineering Metric | Traditional Remove & Replace Method | HEM Full Depth Reclamation (FDR / CIPR) | Operational Gain / Advantage |
|---|---|---|---|
| Material Recycling Rate | 0% – 20% (High off-site disposal rate) | 100% In-Situ Recycled | Eliminates virgin aggregate hauling costs completely |
| Project Duration & Lane Closure | Weeks to Months (Deep excavation required) | 50% to 70% Faster Execution | Immediate traffic release after compaction & curing |
| Carbon Emissions & Energy Use | High fuel burn from truck transport & hot mixing | Reduced CO₂ Footprint by ~75% | Supports global ESG and green infrastructure standards |
| Direct Structural Cost Savings | Baseline 100% (High material procurement cost) | 30% to 50% Lower Direct Cost | Significantly increases project ROI for municipal tenders |
| Subgrade Fatigue & Reflective Cracking | Susceptible to reflective joint cracking | Homogeneous Flexible/Rigid Layer | Distributes wheel loads over broader contact areas |
HEM Group delivers continuous machinery synergy across road rehabilitation, mining aggregate processing, and heavy earthmoving projects.
Heavy-duty deep cold in-place recycling combined with intelligent bitumen distributors and high-density slip-form asphalt paving systems ensures long-lasting pavement strength under severe heavy-truck loads.
Empowering cost-effective rural road upgrade programs. FDR machinery turns low-grade gravel roads into stabilized cementitious base layers prior to surface chip sealing or micro-surfacing application.
Our integrated mobile crushing plants (Jaw, Cone, Impact) and mobile vibrating screens supply perfectly graded crushed aggregates, ensuring smooth raw material feeding for on-site hot mix plants.
Direct factory manufacturing with strict quality control guarantees operational reliability on your jobsites.
Operating from our modern 5,000+ m² facility, HEM Group combines industrial robotics, laser cutting, automated submerged-arc welding, and dynamic hydraulic calibration. Our close proximity to China’s machinery industrial clusters enables complete vertical integration, ensuring low-cost component sourcing without compromising engineering tolerances.
