In 2026, Kyrgyzstan will comprehensively promote the modernization of national roads, covering many key projects such as reconstruction and expansion of national highways, laying of cross-border traffic corridors and upgrading of urban road pavements.As the market demand for high-quality hot mix asphalt continues to soar, the 160 ton/hour intermittent asphalt mixing plant has become the core equipment of local engineering contractors and infrastructure projects.
Compared with continuous drum mixing equipment, intermittent asphalt mixing plant has outstanding advantages such as accurate proportioning, rapid switching of mixture ratio and stable quality of finished materials, which is perfectly suitable for the construction environment of Kyrgyzstan with many mountains and complicated road conditions.In combination with the actual local project in Kyrgyzstan, this paper comprehensively analyzes the 160-ton intermittent asphalt mixing plant suitable for local working conditions from the dimensions of market demand, project overview, equipment structure, production process flow, core technical parameters, efficiency operation and maintenance scheme, application scenario and common fault handling.

In 2026, relying on its own transportation development plan and the implementation of the "Belt and Road" cross-border infrastructure project, Kyrgyzstan will greatly increase road infrastructure investment, and plans to build and renovate hundreds of kilometers of asphalt roads in several states.However, the existing old asphalt mixing equipment in China generally has problems such as low hourly capacity, poor adaptability of mixture formula, unstable measurement accuracy, etc., which can not keep up with the construction rhythm of large-scale highway reconstruction.
From the perspective of geographical climate, Kyrgyzstan is dominated by mountainous and plateau terrain, with great difference in temperature difference between day and night, long and cold winter, scattered construction sites, and high-capacity intermittent mixing station, which can solve local construction pain points from three aspects:
The local area is suitable for outdoor paving operations for a short period of time, and the equipment has high continuous discharge efficiency. It can match the compact construction plan and ensure that the paving project is completed on schedule.
The equipment adopts single pot metering scheme, which can quickly mix ordinary asphalt, modified asphalt and SMA mastic macadam mixture, and adapt to various surface construction standards of expressways, rural roads and urban roads.
The whole machine is divided into modular structure, which can be transported to remote mountain construction sites through intermodal transportation, effectively reducing the time spent on site assembly and commissioning, and adapting to the needs of scattered construction sites.
If there is no stable and reliable asphalt mixing equipment with high production capacity, a series of engineering problems such as insufficient asphalt raw material supply, delay of construction period and uneven pavement quality will easily occur in road projects.

Each pot of raw materials independently weighed, operators can quickly adjust the asphalt aggregate ratio, mineral powder content, modified additive ratio, as required to produce ordinary asphalt concrete, SBS modified asphalt, SMA special pavement mixture;
Compared with higher tonnage equipment, the purchase price, total installed power consumption and floor area of 160 tons mixing plant are lower, which is suitable for the construction land conditions of most projects in Kyrgyzstan.
All thermal insulation layers of hot storage bin, asphalt storage tank and conveying pipeline shall be thickened to reduce heat loss under plateau low temperature environment and stabilize the discharge temperature of finished asphalt;
RAP recycled asphalt addition interface is reserved for the whole machine, and the old pavement milling material recycling module can be installed in the later stage to recycle waste pavement materials and greatly reduce the cost of local road maintenance raw materials.
