In the wave of high-speed development of infrastructure construction in Southeast Asia, high-performance, high-stability, high-precision pavement construction equipment is the core guarantee for the realization of high-quality landing of national key projects.In January 2019, ZOOMLINE independently researched and developed and manufactured ZAP-S320 stationary asphalt mixing plant successfully completed installation and commissioning and officially put into production in Cambodia. This asphalt plant is precisely supporting the key infrastructure project of Cambodia National Highway No. 1, which is procured and applied by China Road and Bridge Engineering Corporation (CRBC), a top domestic centralized enterprise and an internationally renowned engineering contractor. The successful landing of this high-end overseas benchmark project fully verifies the excellent performance and strict quality control system of ZOOMLINE asphalt mixing plant, and highlights the brand’s comprehensive strength to obtain authoritative recognition of the world’s top infrastructure enterprises.
Cambodia National Highway No. 1 is the core trunk road network project in Cambodia’s transportation planning, and it is a representative national landmark infrastructure project in the country, which bears the key mission of regional connectivity and opening up internal and external transportation hubs. After the completion of the project, it effectively improves the road transportation system in Cambodia, accelerates the flow of regional materials, drives industrial upgrading and economic development along the route, and has far-reaching strategic value for the improvement of local people’s livelihoods, urbanization and regional economic and trade development.
This key overseas infrastructure project is fully undertaken by China Road and Bridge Corporation (CRBC). As the world’s top centralized infrastructure enterprise, CRBC is deeply engaged in the field of major construction projects at home and abroad, and has built a set of standardized and highly demanding global supplier selection and equipment access system. For high standard and high specification national road projects such as Cambodia National Highway No.1, CRBC has set up a very high entry threshold for the capacity stability, measurement accuracy, environmental emission standard, continuous operation capability and overseas full-cycle service capability of asphalt mixing plant, and only selects high-quality equipment brands with international first-class manufacturing strength and mature overseas project landing experience.
Cambodia National Highway No.1 has the project characteristics of large construction volume, high construction standard and tight schedule, CRBC faced many construction difficulties during the equipment selection stage, and put forward a series of strict technical and usage requirements for asphalt mixing plant:
High production demand: the overall construction scale of the project is huge, and the demand for long-term continuous operation is outstanding, which requires the asphalt mixing plant to have a stable and high output capacity, and can continuously supply large quantities of high-quality asphalt mixtures around the clock to ensure that the construction process is uninterrupted, and eliminate the problem of delaying the schedule for the lack of production capacity of the asphalt plant.
Strict quality standard: the highway road surface asphalt mixture has the ultimate requirements of proportioning accuracy and material temperature stability, which directly determines the smoothness of the road surface, compaction density, wear-resistant durability and long-term service life, and requires the equipment to achieve high-precision metering, constant-temperature mixing, and constant performance of the material, to ensure the quality of the road surface construction from the source.
Environmental compliance: the local construction site in Cambodia implements strict green environmental control standards, with clear limits for construction dust and exhaust emissions, which requires the asphalt mixing plant to be equipped with a mature and efficient environmental protection and dust removal system to fully meet the local green construction specifications and environmental policy requirements.
Stable operation demand: overseas construction sites have limited operation and maintenance conditions, and equipment maintenance and repair is much more difficult than at home, requiring the asphalt plant structure is rugged and durable, low failure rate, and at the same time has the characteristics of easy operation and convenient maintenance, which can be adapted to the long-term high-intensity continuous construction conditions, and effectively reduce the cost of operation and maintenance of the project and the construction risk.
In the multiple rounds of asphalt plant equipment screening and evaluation of Cambodia National Highway No. 1 project, ZOOMLINE, with its excellent product performance, strict quality control system, mature overseas project delivery capability and good industry reputation, stood out among many similar brands at home and abroad, and successfully became the designated asphalt mixing plant supplier of CRBC.
