Asphalt quality meets standards
Airport road construction is an important project to ensure aviation safety and is the cornerstone for the efficient operation of an aviation hub. Airport roads have to cope with the huge pressure of aircraft landing and taking off, but also to meet the high standard requirements within a limited time.
As the core of the construction, the asphalt mixing plant needs to maintain stable operation, and its production efficiency and quality control directly determines the project progress node and runway operation safety coefficient. Therefore, the asphalt mixing plant must overcome the multi-dimensional technical challenges of raw material ratio optimization, construction efficiency and low equipment failure rate, so as to achieve a seamless connection between construction and airport operation.
Macroad, as an outstanding asphalt plant supplier, always starts from the actual needs of customers, and deeply understands the pain points in airport road construction. Whether it is facing the high standard of asphalt quality requirements or adapting to the tight construction window, we are committed to making the equipment more understanding of the customer’s needs – reducing the risk of downtime with reliable production capacity, and grasping the construction time with rapid deployment technology. With reliable production capacity to reduce the risk of downtime, with rapid deployment technology to seize the construction time, with all-weather stable operation to escort the smooth progress of the project.
We believe that only by truly solving on-site problems can we help our customers pave every inch of the runway with more solidity and reliability.
Airport Road Construction Achieves in Both Quality and Efficiency
Project Characteristics
- Asphalt quality requirements are extremely high: need to withstand the impact of aircraft landing and taking off and aviation fuel corrosion, the runway area leveling requirements, the requirement of uniform mix temperature
- Constrained construction time: subject to air traffic control restrictions, paving and compaction had to be completed within the 3-6 hour night time window.

1.Asphalt Performance Defects: low quality asphalt, insufficient resistance to high-temperature deformation, and easy aging of asphalt
Measuring accuracy guarantee system
- Equipped with hot aggregate metering hopper with cumulative measurement as well as overflow and waste tanks, with automatic compensation for fallout and overweight alarm and locking function to improve weighing accuracy;
- Built-in upper and lower air extraction and dust removal pipeline design, eliminating the airflow-induced weighing value drift, ensuring weighing accuracy;
- Adopting the first batch of error control technology to improve the weighing accuracy and ensure the quality.
Optimization of powder metering structure
- The unloading port of powder bin adopts valve control, which ensures the precision of powder metering;
- Powder metering hopper adopts cone design to ensure full unloading and weighing accuracy.
Dynamic measurement control technology
Dynamic and accurate control of the secondary measurement technology, based on the amount of stone asphalt secondary correction measurement, strictly guarantee the ratio of oil and stone, to avoid the loss of asphalt, but also to ensure the quality of the finished product asphalt.
2.Construction efficiency constraints: high pressure on short-term centralized material supply, high frequency of equipment start-up and shutdown, loss of service life
Optimization of the durability of core components
The use of high-precision boring machine to process the shaft holes, to ensure the concentricity of the shaft end, the mixing shaft in the use of bearing wear is small, long service life, reduce the failure due to wear and tear of the large shaft, so that the equipment is more durable
Drive system synchronization enhancement
The mixing drive adopts the motor and reducer and the big shaft direct connection mode, non-traditional chain drive, transmission synchronization is good, to ensure that the mixing shaft mismatch due to unsynchronized rotation is avoided, reducing the incidence of failure
Vibration system stability design
The vibrating screen adopts 4 layers of double vibration motor linear screen, linear vibrating screen maintenance is convenient, vibration motor work 1500 hours before maintenance; drive device using Bonang worm gear reducer, stable performance, reverse self-locking ability, reduce due to power outages, faults brought about by the sprinkling of material
Optimization of buffer structure
Optimized design of elastic tensioning device, the plate chain works as a buffer, reducing the risk of wear and breakage of the plate chain, reducing the failure rate.
Core equipment selection guide
Facing the requirements of both quality and schedule in the construction of airport roads is undoubtedly a challenge for many asphalt mixing plant manufacturers. Facing the test for the construction of airport roads, stationary asphalt mixing plant and mobile asphalt mixing plant is the answer given by Macroad. Stationary asphalt plant in the asphalt quality to provide enough to meet the airport road on the asphalt quality requirements, in the face of the need to move frequently on the road construction of large airport equipment, mobile asphalt mixing plant can also play its advantages. So that for your project, only according to the local conditions, you can choose the most suitable asphalt mixing plant. Next let us understand the comparison of these two asphalt plant, so that you have a more detailed understanding of the two types of equipment.
