غلطکهای تک درام معمولاً برای عملیات زیر ساختی استفاده میشوند. مشخصه استاندارد این دستگاه این است که هم درام و هم محور عقب دارای نیروی محرک هستند که این ویژگی، توانایی دستگاه را برای اجرای عملیات راهسازی در مسیرهای صعب العبور و حتی شیبهای تند فرآهم میسازد.
غلطکهای هام دارای تکنولوژی Tier 4در موتور دیزل هستند که کارایی دستگاه را به مراتب بالا برده و در عین حال مصرف سوخت را کاهش میدهد.
سری 3000 غلطکها دارای تکنولوژی هام ترونیک[1] هستند که قدرت شیب روی را به مراتب افزایش میدهد. طیف وسیعی از غلطکها که وزن 5 تا 25 تن دارند به درامهای سطح صاف یا پاچه بزی مجهز هستند. در طراحی غلطکهای مجهز به سیستم VIO، هم به روش فشرده سازی هم به روش ویبره (vibration)و هم به روش نوسانی (osillation) صورت میگیرد. به دلیل قابلیتهای بسیار زیاد و گسترده، این غلطک چند منظوره بسیار مقرون به صرفه است.
غلطکهای دو درام آهنی که سیستم فرمان مفصلی برای درام عقب و جلو دارد، به صورت کاملاً مجزا دستور گرفته و فرمان میگیرند. این غلطکها عموماً برای متراکم سازی آسفالت استفاده میشوند. غلطکهایی که در عملیات متراکم سازی آسفالت مورد استفاده قرار میگیرند دارای قابلیت شتابگیری، ترمز گیری هستند و سیستم فرمان بسیار نرم و ملایمی دارند که مانع از ایجاد دست انداز و ناهمواری در سطح آسفالت شود. سیستم سه مفصلی در این سری از دستگاهها، پایداری و قابلیت اطمینان در فرمانپذیری و کنترل دستگاه را تضمین میکند.
این غلطکها بسیار سریع العمل می باشند و کار با آن آسان است. ظاهر زیبای این دستگاه به دلیل وجود تقعر در جلو و عقب دستگاه و همچنین انحنا در کمر دستگاه است. غلطکها دو درام آهنی، سری DVنیز برای متراکم سازی آسفالت استفاده میشوند. این غلطکها قابلیت شتابگیری، ترمزگیری هستند و سیستم فرمان بسیار نرم و ملایمی دارند که مانع از ایجاد دستانداز و ناهمواری در سطح آسفالت شود. این دستگاه دارای دو درام فرمانپذیر مستقل از یکدیگر است و به دلیل وجود دو سیستم سه مفصلی مجزا، باعث میشود تا هر درام جهت دهی جداگانه و یا همزمان داشته باشد.

عملکرد متراکم سازی غلطکهای سه چرخ بر اساس بار خطی استاتیکی بالای آن است که به دلیل وزن بالا و عرض باریک درام میباشد. غلطکهای سه چرخ استاتیکی، برای اتو کردن آسفالت مناسب است.بکارگیریغلطکهای چرخ لاستیکی مدل GRWرا میتوان در پروژههای کوچک و بزرگ در سراسر جهان مشاهده کرد. علاوه بر متراکم سازی استاتیکی، اثر خمیری کردن آسفالت به واسطه استفاده از لاستیکهای پنوماتیکی است که باعث میشود سطح نهایی خوب و آب بندی مناسبی داشته باشد و به طور قابل توجهی برای اتو کردن لایه آسفالت و فشرده سازی مناسب باشد. مدلهای سنگین این نوع غلطک نیز برای عملیات زیر سازی خاک و عملیات بازیافت مناسب هستند.

Nature does not always provide the ideal ground conditions – whether for civil engineering or structural engineering projects. Quite often, the existing soil requires preliminary treatment to improve its bearing capacity. In other places, massive rock formations need to be levelled.
What methods are used for laying the foundations?
The construction of a new road – whether from asphalt or concrete – requires the production of an excellently bonded pavement structure, beginning with a stable base layer and going all the way to a precisely levelled surface course.
What are the most important criteria to be considered? What methods need to be applied? What machines used?
Roads are exposed to tremendous loads that will sooner or later leave their marks on them. A time will come when every road will be in need of a general overhaul. But no two damage patterns are alike.
Which rehabilitation methods offer a cure for distressed roads? What are the differences between them? Which are suitable to be carried out as mobile roadworks?
Natural crushed stone and recycled materials in graded grain sizes are used as standard aggregate for concrete, as well as for base, binder and surface courses in road and building construction. But how are large chunks of rock converted into aggregate of defined size?
Versatility and flexibility in application are the major trump cards that mobile crushers play in comparison to stationary crushing plants. What are mobile crushers used for? What are the differences between the various crushing techniques? What about the hardness of the rock to be processed?
Mobile crushers are used in quarries, in mining, on job sites, and in the recycling industry. The robust plants mounted on crawler tracks are capable of processing both rock and recycling material, producing mineral aggregate and recycled building materials respectively for the construction industry.
When processing natural stone or recycling material like demolition waste, concrete, asphalt, incineration ash or steel slag, an excavator or wheel loader feeds the material into the mobile crusher. Then then produced material is used for road construction or other, similar applications.
Crushing techniques distinguish between pressure crushing and impact crushing. Jaw crushers or cone crushers use the so-called pressure crushing technique where material is reduced in size mainly by high pressure between slow-moving wear parts. Impact crushers use the so-called impact crushing technique, in which the rock is accelerated by a massive fast-moving rotor and reduced in size by impacting against breaker walls. Jaw crushers are widely used for crushing medium-hard to hard rock, and are mostly used as primary crushers. Impact crushers work as both primary and secondary crushers for processing soft to medium-hard rock, producing larger quantities of fines. Cone crushers are used predominantly as secondary crushers for hard rock.
A comparison of renewal projects and newly built roads reveals that the number of renewed roads is significantly higher than the number of newly built roads.
To address environmental protection, efforts are made to reintroduce the high volume of RAP material into the materials cycle and to reuse a very high ratio. Since the 1970s, an effort has been made to recycle an increasing volume of reclaimed asphalt while continuously optimizing the energy-intensive process of asphalt production.
The highest theoretical additive volume of used asphalt mainly depends on its grading curve or, in other words, on its ingredients with regard to volume, size and composition. It therefore has to be one of the objectives to reconcile the grading curve of the crushed asphalt as much as possible with the grading curve of the final asphalt product.
Another significant benefit of this grinding technology is the substantially reduced generation of fine particles – the crucial advantage which prevents blockage of the transport paths and the parallel drum in the asphalt mixing plant as much as possible, providing ideal preconditions for feeding RAP into the asphalt mixing plant (up to 90% + x).

he BENNINGHOVEN granulator gently separates the reclaimed asphalt into its individual components – without destroying the original grain structure. This gentle grinding technology is the perfect precondition for nearly 100% re-use of the RAP material.
Another significant benefit of this grinding technology is the substantially reduced generation of fine particles – the crucial advantage which prevents blockage of the transport paths and the parallel drum in the asphalt mixing plant as much as possible, providing ideal preconditions for feeding RAP into the asphalt mixing plant (up to 90% + x).
