Explore our industrial-grade road building, pavement maintenance, and high-efficiency bitumen modification plants engineered for worldwide infrastructure projects.
The global pavement engineering landscape is undergoing a paradigm shift toward sustainable, durable, and heavy-load resilient infrastructure. **Rubber Modified Asphalt Plants (RMAP)** stand at the epicenter of this transition. By recycling end-of-life tire rubber into high-value Crumb Rubber Modifier (CRM), road construction agencies and municipal contractors solve dual challenges: converting hazardous scrap tires into high-performance binders while extending pavement lifespan by 200% to 300%.
Modern highway authorities demand compliance with net-zero carbon targets. A typical 20 t/h Rubber Modified Asphalt Plant consumes roughly 1,500 to 2,000 recycled truck tires per kilometer of 4-lane highway, diverting non-biodegradable waste from landfills and drastically reducing virgin SBS polymer consumption.
The industry has evolved beyond basic wet-process asphalt rubber. Next-generation plants utilize dynamic double-stage high-shear milling units that homogenize hybrid binders incorporating SBS, crumb rubber (30–80 mesh), and chemical devulcanization agents for permanent storage stability without phase separation.
Legacy manual batching is obsolete. Today's global procurement standard requires fully automated PLC-driven metering systems, mass flow meters, real-time viscosity tracking, and cloud-integrated thermal oil temperature regulation ensuring batch-to-batch repeatability.
International contractors, Ministries of Transport (MoT), and asphalt batching plant operators mandate stringent engineering metrics before sourcing modified bitumen equipment from China. Below is a comparative technical analysis illustrating how OEM China Rubber Modified Asphalt Plants fulfill international standards (ASTM D6114, EN 14023, AASHTO M320).
| Performance Specification | Traditional Polymer Plant | HEM High-Shear Rubber Modified Asphalt Plant | Impact on Pavement Quality |
|---|---|---|---|
| High-Shear Milling Velocity | 2800 – 3000 RPM | 4500 – 5000 RPM (Variable Frequency) | Achieves ultra-fine rubber particle cleavage (<5 μm) ensuring stable suspension. |
| Crumb Rubber Dosage | 3% – 5% Maximum | 10% – 25% High-Concentration Loading | Significantly improves high-temperature rutting resistance and low-temperature flexibility. |
| Swelling & Reaction System | Single-Agitator Tank | Multi-Stage Thermal Oil Swelling Tanks w/ Anti-Settling Agitators | Ensures full devulcanization and swelling of rubber particles into the bitumen matrix. |
| Storage Stability (Tube Test) | Softening Point Diff > 5°C | Softening Point Diff < 2.5°C (Storage Stable) | Eliminates segregation during long-distance tanker transportation or static storage. |
| Environmental Control | Basic Venting | Integrated VOC Scrubber & Thermal Oxidizer Connection | Zero blue smoke emissions; fully compliant with EU and EPA environmental regulations. |
Founded in 1998 as Xi'an Hongda Communications Technology Co., Ltd. by an esteemed group of professors from Chang'an University—China's premier university for highway engineering and heavy machinery design—HEM Group represents over two decades of rigorous mechanical academic research applied to industrial asphalt production.
Recognized in 2006 as a official "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology, our engineering institute holds multiple patents spanning mechanical dynamics, engine power matching, hydraulic transmission technology, and digital electronic control systems.
In 2017, to streamline global export sales and technical assistance, HME TOP Machinery Equipment Co., Ltd. was established. Today, we deliver end-to-end turnkey machinery solutions tailored to demanding road infrastructure programs worldwide.
Our state-of-the-art facilities combine precision laser cutting, automated robotic welding, and dynamic rotor balancing test beds for continuous high-shear mills.
Procuring a Rubber Modified Asphalt Plant from China standardizes capital expenditure without compromising precision engineering. By leveraging fully integrated heavy industrial supply chains in Shaanxi and surrounding machinery manufacturing hubs, HEM Group offers distinct technical advantages:
Assures binder resilience under intense commercial truck axle loads. The crumb rubber network absorbs dynamic stress, preventing permanent deformation (rutting) at high summer temperatures exceeding 60°C pavement surfaces.
High shear rubber modified bitumen delivers elevated elastic recovery, shear resistance, and fuel-spill resistance necessary for aircraft landing impacts and heavy container handler traffic.
Open-Graded Friction Course (OGFC) asphalt mixes incorporating rubberized bitumen reduce tire noise dramatically while accelerating rainwater drainage to reduce hydroplaning.
Proven in desert climates (Middle East/Africa) and sub-zero freeze-thaw regions (Northern Europe/Central Asia), maintaining cracking resistance down to -30°C.
HEM Group provides a comprehensive product portfolio supporting road contractors from raw quarry aggregate crushing to final asphalt compaction and ongoing surface rehabilitation.
From asphalt mixing plants and pavers to chip sealers and bitumen decanters, our machines deliver uniform density and superior ride smoothness.
Leading environmental road maintenance solutions utilizing Cold In-Place Recycling (CIPR) and micro-surfacing technologies.
Heavy-duty excavators, backhoe loaders, mobile crushers, and screens built to withstand harsh mining and earthwork environments.
Trusted by infrastructure departments and engineering groups in over 60 countries across Asia, Africa, Eastern Europe, South America, and Oceania.
Direct manufacturer supply with full OEM customization, technical guidance, and competitive factory pricing.
