Asphalt production:
the secret is in the mixing

A thermal mixing process is required to produce asphalt from aggregate and bitumen for road construction and an asphalt mixing plant is essential here. Whether road-mobile, transportable or stationary – every mixture is a winner with tailor-made solutions by BENNINGHOVEN, the specialist for asphalt mixing plants.

Production process

We generally differentiate between two types of processes in asphalt production: continuous production and discontinuous or batch production.

Continuous production

In continuous production, there is no interruption to the mixing process. The individual components are continuously added to the mixing process. This process is particularly suited to large building projects requiring an aggregate or recipe that does not vary.

Discontinuous / Batch production

In batch production, the components of the asphalt mixture are first weighed before being mixed in batches in an asphalt mixer according to a specific recipe. This process is more flexible as the recipe for the mixture can be changed for each batch. What is more, a greater mixing quality can be achieved due to the more precise quantities added and adapted mixing cycles.

In Europe, the batch production process is the most widespread type of asphalt production.

The right type of asphalt mixing plant for the intended purpose

While road-mobile and semi-mobile plants are usually used in areas with a less-developed infrastructure, high-performance stationary plants are normally popular in conurbations. BENNINGHOVEN provides flexible solutions for reliable and economic use and each BENNINGHOVEN plant is suitable for the production of both roller-compacted and mastic asphalt.

Stationary asphalt mixing plants

High-performance, stationary plants are more commonly used in conurbations. They are usually positioned at an easily accessible location, allowing for delivery to as large an area as possible while keeping delivery routes to building sites short. They are found, for example, close to motorway exits or in industrial estates in large cities. Some stationary asphalt mixing plants are located directly at mineral deposit sites such as quarries in order to minimize the cost of mineral aggregate deliveries. This type of plant requires a concrete foundation.

Transportable asphalt mixing plants

Transportable or semi-mobile plants are suitable for job sites which will only be operating for a specific period of time. They are generally acquired with the option of moving the plant to a different location, if required. This type of plant can be fitted with a fixed concrete foundation or a mobile steel foundation.

Transportable asphalt mixing plants in container design

The BENNINGHOVEN asphalt mixing plant in container design ECO can be used as a stationary plant but can also be moved to a new location quickly and without any problems. Production in standardized ISO sizes allows for easy transport and reduced erection times.

Road-mobile asphalt mixing plants

Road-mobile plants are suitable for job sites which will only be operating for a specific period of time. This plant is moved together with the mobile roadworks from one works section to the next. At the assembly site, the road-mobile asphalt mixing plant only needs a space that can be accessed by a truck for its foundation.

Customized Solutions

Whether standard or customized – BENNINGHOVEN asphalt mixing plants come with a vast range of equipment options. An ideal solution can be found to cater each and every market requirement. From mobile to stationary, with capacities ranging from 80 - 400 t/h – one thing never changes: BENNINGHOVEN plants stand for optimum mixture quality.
