Cold Mix (Mechanical Stabilization) Asphalt Plant

PMT (plant-mix base) materials are prepared by mixing at least three different types of aggregates with a certain proportion of water in the mechanical plant by passing through the primary crushing and screening process, which is used in the formation of the plant-mix base layer of the road body. On the road, the laying process is carried out with a paver.

E-MAK is a young and dynamic member of Simge Group, which has been operating since 1977. With its technology and products, E-MAK became the one and only asphalt producers of Turkey, in a very short time. E-MAK, which is completely domestic and national, exports more than one product to many countries abroad.

PMT base materials are prepared by mixing at least three different types of aggregates with a certain proportion of water in the mechanical plant, through primary crushing and screening processes, which are used to form the plant-mix base layer of the road body. On the road, the laying process is carried out with a paver. It is produced in the form of PMT Type-1 and PMT Type-2 following the Highway Technical Specification Section 402.04 and the TS EN 13242 standard. It is obtained by mixing at the optimum water content in E-MAK automatic mechanical stabilization plants by using at least 3 different aggregate groups in its production.

The low bearing capacity of the existing floors makes it necessary to reinforce them. Otherwise, the hot mix asphalt to be applied to the ground may be subject to collapses and fractures depending on the ground below. Plantmix material should be used before asphalt application to strengthen the ground and remove undulations on the existing surface. Plantmix is obtained by mixing the appropriate amount of aggregate and stone dust in the plant.

Plantmix reduces the thickness of the superstructure by at least one third compared to the stabilized foundation. Even on a road with the least traffic, the stabilized foundation layer goes up to 58 cm. In a main artery with heavy vehicle traffic, we see that this thickness reaches a very high thickness of 120 cm.

The formation of pits on the existing ground causes an increase in the amount of asphalt to be used. To prevent this from happening, the ground surface before asphalt should be covered with plantmix base material. Removing the unevenness and pitting on the floor causes savings in the coating material. Thus, the total cost is much more affordable.

How E-MAK PMT Works

This foundation layer needs to be designed. It is designed according to the percentages passing according to the sieves used in the crushers production in line with the 15-day sieve analysis average. Some construction sites make a mixture of 3 and 4. It is more convenient to prepare and break the 3 of the mixtures in the construction site environment. Because its efficiency is higher. Namely, crushed material types enter the mixture as 0-10 mm, 10-19 mm, 19-38 mm.

In the 4 typed mixtures it is broken into 19-38 mm, 12-19 mm, 5-12 mm, 0-5 mm. This situation may differ according to the sieve diameter in the crusher.

Plant Mix layer should be prepared following BSK laying on the substrate and should be strong in terms of compression. The density prepared with the modified proctor method must be equal to 100% on the road.

There should not be any foreign materials such as clay and silt in the Plant Mix layer. If it is produced from solid clean aggregate, it is possible to obtain high efficiency on the road. The undulation that will occur during laying should be minimized in this layer, otherwise the undulations on the way will cause the same effect on the BSK surface.

Plant Mix, which is produced from a special and strong alloy resistant to wear, is one of the basic aggregate preparation systems.

The mechanical plant works automatically. If necessary, you can operate it manually. Dosing bands of Cold Aggregate Silos; It is connected with the electric motor and has the feature of stepless dosage adjustment. During production, the belt speeds can be brought to the desired level from the control cabinet with the speed control unit. There are 4 layers of cord fabric on the 1000 mm wide belt. The movement of the total bands is directly integrated with the motor-reducer group of at least 11 kW. The parts in which the mixture is made in the mixer consist of wear resistant exchangeable steel cast plates (Ni Hard 4). Mixer arms are made of cast steel material and prepare the mixture in a way that does not leave a swept place in the mixer. The automation system is operated with automatic control control.

E-MAK always stands by its customers not only during pre-sales and sales but also after sales.
