Municipal road renovation and traffic infrastructure upgrading projects in Dhaka, Bangladesh, South Asia have long faced severe construction environment constraints. High temperature and scorching heat all year round, concentrated heavy rainfall in rainy season, high dust pollution on construction site, coupled with increasingly strict local environmental protection policies, make it difficult for conventional standard asphalt mixing plants to adapt. Ordinary asphalt plant generally has problems such as capacity fluctuation, frequent shutdown failure, substandard mixture quality, excessive emission, etc., which seriously slows down the construction progress and affects the pavement construction quality. In response to the harsh construction pain points in South Asia, ZOOMLINE launched a customized ZAP-S80 80TPH stationary batch type asphalt mixing plant, which officially landed in Dhaka in 2021. With stable 80 tons/hour capacity, precise grading control system and energy-saving and environment-friendly operation advantages, the equipment solves local infrastructure construction problems in one stop and continuously delivers high-quality asphalt mixture for infrastructure construction in Dhaka and surrounding areas.
The customized asphalt mixing plant landing project is located in Dhaka, the capital of Bangladesh. The equipment model is ZOOMLINE ZAP-S80 stationary asphalt mixing plant. The installation and commissioning were completed and officially put into operation in July 2021. The project is a benchmark customized project for ZOOMLINE to deeply cultivate the infrastructure market in South Asia. The core services are key infrastructure projects such as Dhaka municipal road reconstruction and urban traffic network upgrading. It is also a typical case of localization adaptation of medium and high-end engineering equipment in China-Bangladesh infrastructure cooperation. It is specially tailored for the harsh construction scenarios of high temperature, high humidity and high dust in South Asia.
The client of this cooperation is a well-known local engineering contractor in Bangladesh, undertaking key infrastructure projects such as municipal road renovation, traffic trunk line reconstruction and expansion, urban and rural road network improvement in Dhaka and surrounding areas for a long time. The customer has been deeply engaged in the local infrastructure industry for many years, with huge project volume and concentrated construction cycle, and has long-term, large-scale and uninterrupted supply demand for asphalt mixture. At the same time, municipal infrastructure projects have strict standards for pavement flatness, durability and construction qualification rate, so customers put forward extremely high requirements for the operation stability, production efficiency, mixture quality and environmental compliance of bitumen mixing plants.
Dhaka’s special geographical climate and construction environment make it difficult for general asphalt batching plants to adapt. Customers have long faced multiple construction problems, which are mainly divided into two dimensions: natural environment constraints and equipment operation and construction.
In view of multiple construction bottlenecks, customers abandoned the traditional general asphalt batch mix plant procurement ideas and defined precise equipment investment and upgrading objectives:
One is to purchase specialized customized bitumen batch mix plants suitable for South Asia’s high temperature, rainy and high dust conditions to solve the equipment adaptability problem from the root cause;
The second is to achieve 80TPH stable continuous production capacity and match the high-intensity and uninterrupted supply demand of infrastructure construction materials.
Third, relying on high-precision mixing control system, ensure the quality of asphalt mixture, improve pavement construction standards and project acceptance rate;
Fourth, realize low energy consumption and ultra-low emission green production, conform to local environmental protection policies, and reduce long-term operation energy consumption costs and compliance risks.
ZOOMLINE iteratively optimizes the parameters of the whole system of ZAP-S80 asphalt mixing plant in combination with local climate characteristics, construction intensity, environmental protection standards and customer core requirements in Dhaka.
