XCMG has built a complete set of systematic road construction techniques spanning from subgrade treatment to pavement formation and maintenance renewal, ensuring seamless connection, precision and efficiency for every process step.
With the continuous acceleration of global infrastructure development, road engineering imposes higher demands on construction equipment: not only must it be efficient and reliable, but it must also form systematic and intelligent construction synergy.
XCMG boasts a full range of road machinery products — bulldozers, motor graders, rollers, pavers, milling machines and cold recyclers — built for this purpose.
Construction preparation and site clearing
The starting point of road construction is site preparation. XCMG bulldozers play a key role in clearing, levelling and earthmoving.
Their powerful powertrain, elevated drive structure and reinforced chassis design ensure traction and stability in complex terrains such as rocky soil, mud and soft ground.
The blade can perform combined movements including lifting, tilting and angle adjustment, enabling both rough grading and efficient operation on slopes, ditches and other complex working conditions.
Bulldozer operations provide a level, stable foundation for subgrade construction, establishing a prerequisite for subsequent shaping and compaction.
Subgrade shaping and grading
After bulldozer work is completed, XCMG motor graders undertake fine grading tasks. Their adjustable mouldboard and load-sensing hydraulic system make shaping operations more flexible and precise.
Operators can adjust the mouldboard angle and depth in real time based on the road design’s longitudinal and cross slopes, achieving millimetre-level precision control.
Paired with the 3D intelligent control system, the motor graders can automatically complete slope correction and cross-section forming, improving subgrade accuracy and construction efficiency and providing ideal geometric conditions for the compaction layer.
Subgrade compaction
Compaction is a core link determining road lifespan and load-bearing capacity. The XCMG roller family — single-drum, double-drum and pneumatic tyre rollers — forms a multi-level compaction system from deep layers to surface layers.
Single-drum rollers, with high amplitude and large centrifugal force, achieve densification of deep fill and rock layers.
Double-drum rollers ensure uniform compaction of middle and upper-layer materials with high-frequency vibration.
Pneumatic tyre rollers eliminate surface voids through flexible kneading compaction, resulting in more uniform density distribution.
The intelligent compaction system displays vibration frequency, amplitude and compaction density in real time, automatically identifies under-compacted and over-compacted areas and optimises vibration parameters through algorithms to avoid structural damage from over-rolling, thereby ensuring compaction quality and construction efficiency.
Base and surface course paving
When the base layer compaction is complete, XCMG pavers take centre stage. This equipment is suitable for asphalt and stabilised soil construction, utilising a hydraulic independent drive system and load-sensing control technology to ensure stable power output.
The paving screed employs a double-beam support and eccentric suspension torque-limiting structure, increasing deformation resistance by 30 per cent. Combined with the single tamping compaction device, it enhances pavement density and smoothness.
The operating system features wireless remote control and a multi-function display interface, enabling remote monitoring and precise parameter adjustment. Coordinated with subsequent final rolling by rollers, road surface smoothness and appearance quality reach internationally advanced levels.
Milling and recycling
In road maintenance, rehabilitation and widening projects, XCMG milling machines and cold recyclers constitute an efficient and environmentally friendly system for old pavement recycling.
Milling machines are responsible for precisely cutting the old pavement surface. They can achieve rapid switching between different widths and depths via a quick-change milling drum system.
The fourth-generation base frame and optimised transmission system ensure stable material discharge and reliability even under heavy loads.
Cold recyclers pulverise the old material in place, mixing it with recycling agents (cement, lime or water) to achieve in situ recycling. This recycling process not only reduces the consumption of new materials and transportation costs but also cuts carbon emissions, aligning with sustainable construction concepts.
Operator comfort and safety assurance
Beyond mechanical performance, XCMG road products also focus on operational safety and ergonomic comfort.
The cab features a fully enclosed, vibration-damped design with a wide-view layout. The seat is multi-directionally adjustable and equipped with air conditioning and a noise reduction system.
All equipment meets ROPS/FOPS protection certification and is equipped with panoramic camera systems and intelligent monitoring systems to ensure safe and controllable operation in complex working conditions.
Efficient construction processes need continuous support. XCMG’s global service network covers major engineering markets, providing spare parts reserves, preventive maintenance and remote diagnostic support.
On site, the remote service platform enables early fault warning and parameter calibration, ensuring stable progress of the process flow, with both construction cycle and quality being controllable.
Forming an intelligent road building ecosystem
Future road construction will be an intelligent, interconnected, systematic project.
XCMG, with its complete product sets, intelligent technology and green concepts, creates a total process solution from foundation to surface layer and from new construction to recycling, enabling road construction to evolve from traditional mechanical coordination to a digital ecological synergy.
Behind every new road lies not just the roar of steel and machinery but also the crystallised wisdom of XCMG’s systematic road construction techniques — making every stretch of road a link connecting the world to the future.
