Intelligent synergised techniques from foundation to surface layer

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.
