High-efficiency road construction systems precision-engineered to deliver operational uptime and low total cost of ownership under DNIT & DER specifications.
Navigating Highway Concessions, High-Load Logistics Corridors, and Tropical Pavement Challenges
Brazil represents the largest transport infrastructure market in Latin America, characterized by an extensive road network exceeding 1.7 million kilometers. As the primary backbone of the national economy, highways account for over 65% of freight movement and 95% of passenger traffic across the country. With major initiatives such as the federal Novo PAC (Programa de Aceleração do Crescimento) and accelerating private concession auctions supervised by ANTT (Agência Nacional de Transportes Terrestres), Brazil is undergoing a structural overhaul of its transport arteries.
Substantial public and private capital deployments aimed at expanding capacity, dualizing single-lane highways, and rehabilitating key export corridors linking agricultural hubs to coastal ports.
Agricultural corridors like BR-163, BR-364, and BR-101 experience continuous extreme axle weight from triple-trailer B-double combinations (9-axis road trains), necessitating fatigue-resistant asphalt formulations.
High ambient temperatures combined with intense seasonal monsoon rainfall cause rapid thermal oxidation, stripping, and subgrade softening if pavement processing lacks precise binder metering.
Due to the high cost of virgin bitumen and long hauling distances across states like Mato Grosso, Bahia, and Minas Gerais, Brazilian contractors are increasingly turning to Cold In-Place Recycling (CIPR) and Synchronized Surface Treatment (Chip Sealing). Machinery operating in Brazil must feature high-torque milling drums, automated emulsion metering, and robust cooling packages capable of continuous duty in 45°C ambient heat.
Strict Adherence to Regulatory Standard NR-12, CONAMA Environmental Mandates, and DNIT Technical Specifications
Importing equipment into Brazil requires strict compliance with Norma Regulamentadora 12 (NR-12), governing machinery safety, operator protection, emergency stops, electrical safety systems, and physical safeguarding. Our dedicated manufacturing line offers custom OEM packages equipped with safety interlocks, certified ROPS/FOPS cabins, fully enclosed moving parts, and dual-circuit braking systems directly compliant with Brazilian labor safety regulations.
Standard machinery designed for temperate zones frequently encounters hydraulic overheating and power derating in Brazilian regions such as the Centro-Oeste and Nordeste. Our equipment is outfitted with heavy-duty aluminum radiator stacks, variable-speed hydraulic fans, and tropical-grade engine cooling jackets engineered to sustain continuous full-load operations under ambient temperatures up to 50°C.
Brazilian paving practice widely employs modified bitumen, including SBS (Styrene-Butadiene-Styrene) polymers, crumb rubber from recycled tires, and asphalt emulsions (GAP, CQS). Our intelligent bitumen distributors and synchronized chip sealers integrate zero-dead-zone heating circuits, self-cleaning spray bars, and micro-processor controlled mass flow sensors calibrated specifically for high-viscosity modified binders.
To align with environmental standards established by IBAMA / CONAMA, our engine power plants offer optimized fuel injection maps, minimal exhaust emissions, low noise footprints, and high energy efficiency, enabling contractors to bid seamlessly on municipal, state (DER), and federal (DNIT) tender proposals.

Bridging Academic Dynamic Research with Heavy Machinery Manufacturing Since 1998
HEM Group was founded in 1998 by a distinguished group of professors from Chang'an University—China's premier institution for highway engineering and machinery research—alongside leading experts in the road building industry. Originally established as Xi'an Hongda Communications Technology Co., Ltd., the company stands as the earliest high-tech enterprise dedicated to independent research, design, and manufacturing of road construction equipment in China.
Since its inception, HEM Group has adhered strictly to high-tech R&D principles, aiming to build an international brand for construction machinery. Focusing on high-end road maintenance equipment, the company has secured a vast series of invention patents and breakthrough scientific achievements in mechanical dynamics, engine power matching, hydraulic transmission technology, and digital electronic control systems. In 2006, the organization was officially recognized as a "High-Tech Enterprise" by the Shaanxi Provincial Department of Science and Technology.
In 2017, to accelerate global trade and streamline technical partnerships, the group established its international branch: HME TOP Machinery Equipment Co., Ltd. This division oversees international technical exchanges, product export operations, global spare parts distribution, and localized technical field support. Today, HEM has developed a complete, vertically integrated chain of road construction and maintenance machinery, delivering one-stop solutions to contractors across South America, Africa, Asia, and Eastern Europe.
Our product portfolio spans the full spectrum of transport infrastructure development:
Over two decades of continuous manufacturing refinement backed by academic engineering heritage.
Comprehensive mix design, material processing advice, and site-level application engineering.
Tailor-made modifications for NR-12 compliance, tropical cooling, and specialized job-site needs.
Round-the-clock online diagnostic support, remote telematics, and rapid engineer dispatch.
Established support and service partnerships in South America, Southeast Asia, Africa, and Central Asia.
Delivering premium component reliability (Bosch Rexroth, Cummins, Danfoss) at direct factory pricing.
Streamlined Customs Support, Port Clearance, Spare Parts Warehousing, and On-Site Field Commissioning
