He has helped engineering firms and overseas clients select and deploy HZS series batching plants and WBZ series stabilized soil mixing plants for commercial concrete, highway, water conservancy and overseas construction projects.
This WBZ800 Stabilized Soil Mixing Plant Case Study demonstrates how high-output mixing equipment solved tough on-site challenges for large highway widening and reconstruction projects.
When contractors source a stabilized soil mixing plant for highway expansion, capacity, batching accuracy and field durability become make‑or‑break factors.
Project Background: Complex Conditions for the G70 Highway Upgrade
The G70 Highway Expansion Project covers a 120‑kilometer road section in Northwest China. Construction teams faced complicated terrain and highly variable soil conditions.
The newly‑built road base and sub‑base needed to withstand heavy‑duty traffic as well as dramatic seasonal temperature changes.
To build a long‑lasting pavement structure, the project required continuous, large‑volume supplies of premium cement‑stabilized aggregate for base and sub‑base layers. Quality consistency was non‑negotiable for the whole highway widening work.
What challenges do remote highway expansion projects face for soil‑stabilized base construction?

For this WBZ800 Stabilized Soil Mixing Plant Case Study, contractors initially considered using multiple scattered small mixing plants for soil stabilization. However, this traditional approach brought obvious drawbacks.
- Poor logistical management and inconsistent quality control across dispersed mixing points
- Tight construction schedules plus remote working locations
- Strict engineering tolerance requirements: water content accuracy within ±1.5% and cement dosage precision at ±0.5%
Unevenly mixed stabilized material would create weak zones in the road base.
This risked ground settlement, expensive rework, project delays and budget overruns. The project needed one powerful central mixing solution.
Compared with multiple scattered small mixing plants, one centralized WBZ800 stabilized soil mixing station simplifies site management, unifies batching precision, cuts cross‑site transportation cost, and avoids inconsistent mixture quality among different mixing points.
Why Choose the WBZ800 Stabilized Soil Mixing Plant? A G70 Highway Case Study
The main contractor finally chose the WBZ800 Stabilized Soil Mixing Plant as the core continuous production unit for the whole site.
Known for its stable performance, high throughput and precise batching, this 800t/h cement‑stabilized aggregate mixing plant perfectly matched the project’s rigorous demands.
Core Technical Advantages Put Into Practice
- High Production Capacity Speeds Up Construction Featuring continuous mixing technology, the WBZ800 reaches a theoretical output of 800 tons per hour. Such strong production capacity keeps pace with multi‑team paving operations. Thanks to this mixing station, the soil stabilization phase moved forward far ahead of the original timeline.
- Superior Mixing Homogeneity Guarantees Material Performance Equipped with twin‑shaft mixing paddles, the WBZ800 fully blends soil, cement and water. Every batch of finished stabilized soil obtains uniform performance. Core sampling tests on‑site verified that all mixtures satisfied the project’s strict compressive‑strength standards for highway base courses.
- Computer‑Driven Precision Batching Reduces Material Waste Its PLC‑based automatic batching system works with high‑precision sensors and actuators. It accurately proportions every raw material. Exact cement and water ratios prevent waste of costly binders, and secure the structural integrity of the highway sub‑base.
- Heavy‑Duty Build for Harsh Field Environments Northwest construction sites are often dusty with wide temperature swings. The heavy‑duty frame and sealed component design of the WBZ800 lower maintenance‑related downtime. The mixing plant maintained steady round‑run material supply even under tough local site conditions.
