LB Series Asphalt Mixing Plant for Highway Construction
In modern road and bridge construction, technological advancement not only improves project quality but also accelerates construction progress. The asphalt mixing plant is a prime example of this progress. As a key piece of equipment in contemporary road construction, asphalt mixing plants play an indispensable role in infrastructure projects thanks to precise metering, stable output, and excellent quality of finished asphalt mixtures.
The LB asphalt mixing plants manufactured by HAOMEI Machinery adopt a forced batch mixing process and a modular design, making transportation and installation convenient and efficient. Their technical performance reaches advanced international standards, enabling the production of high-quality asphalt mixtures under various environmental conditions. With features such as accurate weighing, advanced control systems, and energy-saving, environmentally friendly operation, they are widely used in the construction of high-grade highways, airports, ports, and municipal roads.
Available models: LB800, LB1000, LB1500, LB2000, etc. Customers can select the appropriate model according to project requirements.

Structure and Working Principle of the LB Series Asphalt Mixing Plant
The LB series belongs to batch-type asphalt mixing plants, mainly consisting of the following systems:
Cold aggregate feeding system
Drying and heating system
Hot aggregate screening and storage system
Weighing system (aggregate, filler, asphalt)
Forced mixing system
Finished mixture storage and discharge system
Centralized control system
Through batch-by-batch precise weighing and forced mixing, the LB series ensures highly consistent quality for every batch of asphalt mixture, making it particularly suitable for the stringent requirements of highway pavement structural layers.
Why Choose an Asphalt Mixing Plant for Highway Construction?
1. Uniform mixture quality
The LB series ensures accurate aggregate gradation and asphalt content through precise proportioning and mixing control, effectively reducing the risk of pavement cracking and settlement.
2. Adaptability to complex terrain and climate conditions
Low-temperature start-up: Capable of normal operation at temperatures as low as -10°C, suitable for winter construction.
High-temperature protection: Hot air temperature can reach 200-260°C, ensuring complete asphalt melting for projects in hot regions.
3. Reduced construction costs
High material utilization: Waste heat recovery and refined screening systems reduce material waste, saving up to 15-20% in annual costs.
Low maintenance costs: Key components (such as mixers and drive shafts) are made of imported materials, with service life exceeding 10 years.
4. Dual dust removal system
A combination of a primary cyclone dust collector and a secondary bag filter keeps emissions below 20 mg/Nm³, making the plant suitable for projects near urban areas.
5. Automated control
The LB series is equipped with a fully automatic PLC control system, enabling automatic proportioning, automated production, fault alarms, and data recording. This significantly reduces manual operation errors and improves overall construction efficiency.
Typical Applications of the LB Series Asphalt Mixing Plant in Highway Construction
In highway projects, the LB series asphalt mixing plants are mainly used for:
Base course and surface course construction of highways
Major and medium-scale maintenance projects
Construction of high-grade highways and urban expressways
Bridge deck paving and service area road construction
