For reclaimed asphalt pavement (RAP) materials, in order to optimize their reuse at proportions ranging from 20% to 80%, it is essential to address several key technical challenges. These include the removal of aged asphalt from the RAP surface, accurate aggregate gradation, elimination of false particles and pseudo gradation, and stabilization of the surface asphalt content and its activity.
These measures aim to enhance the gradation consistency of the RAP, promote effective blending and penetration between aged and virgin asphalt, reduce variability in the final mixture, and ensure that the asphalt mixture meets all required technical performance standards.
Therefore, Tower type RAP asphalt recycling plant is necessary to carry out moderate asphalt stripping, grading, and removal of false aggregates and pseudo gradation. In response to these needs, specialized RAP recycling and processing equipment has been developed.
The Asphalt Recycling Plant can be configured with multiple process options based on the source and characteristics of RAP and the intended use requirements. Configurations include:
(1)Simple grading without asphalt stripping
(2)Basic stripping with three-grade material separation
(3)Fine stripping with five-grade separation (e.g., 0–3 mm or 0–5 mm suitable for asphalt mortar in patching works or cold addition and asphalt extraction)
(4)Micro-crushing into asphalt powder for centrifugal extraction or post-modification, enabling its application in new energy battery materials. 2.Asphalt Aging Response & Binder Selection
(1)Severely aged asphalt has reduced viscosity, making it easier to strip.
(2)Fresh asphalt is more difficult to strip.
(3)Lower temperatures favor easier asphalt detachment compared to high temperatures. Based on the degree of RAP aging, the Recycled Asphalt Pavement Production Plant adjusts the softening point of virgin binders—typically opting for asphalt with lower viscosity or higher ductility to achieve better compatibility.
3.Versatile Asphalt Stripping Techniques (1)Physical stripping (mechanical separation), which is cost-effective and efficient
(2)Chemical stripping using organic alkaline solvents, centrifugal extraction, or thermal distillation
(3)Biological stripping methods, which are still in development for specialized applications

Range of Configuration
1.High-Ratio RAP Recycling in Asphalt Mixes
The Tower Type RAP Asphalt Recycling Plant is designed for high-percentage RAP integration (up to 80%) into new asphalt mixtures. Recycled Asphalt pavement Production Plant ensures uniform blending of reclaimed and virgin materials, reducing costs while maintaining pavement performance.
2.Full-Depth Reclamation and Pavement Maintenance As part of a modern Recycled Asphalt Pavement Production Plant, this system is used in full-depth pavement reconstruction projects. It recycles milled asphalt into new base or surface layers for highways, urban roads, and airports.
3.Grading and Reactivation of Aged Asphalt Materials The Asphalt Recycling Plant facilitates precise grading, stripping, and rejuvenation of aged asphalt. It helps stabilize aggregate gradation and restores binder properties for consistent hot-mix production.
4.Cold and Warm Mix Asphalt Production Integrated with modern control systems, the Tower Type RAP Asphalt Recycling Plant can produce both warm mix and cold recycled asphalt, making it versatile for energy-efficient and eco-friendly pavement solutions.
5.Special Applications – Patch Materials & Binder Extraction This Asphalt Recycling Plant can also be adapted for producing fine recycled asphalt mortar for patching and small-scale repairs, or for binder extraction and refinement in a Recycled Asphalt Pavement Production Plant.
6.Integration in Smart Asphalt Mixing Stations The Tower Type RAP Asphalt Recycling Plant is often part of fully automated smart mixing stations. It integrates with batching, dust removal, temperature control, and storage systems to optimize overall plant efficiency.
Can the equipment be customized according to customer requirements?

Is Ninon provide installation and commissioning services?
Yes, we provide comprehensive installation and commissioning support, either on-site or through remote technical assistance, to ensure optimal equipment performance.
What is the warranty period for the products?
The standard warranty period for most core equipment is generally 12 months, with exact terms defined in the purchase agreement.
How to Choose the Most Suitable Equipment?
First, customers should provide information on the type and hardness of local raw materials (e.g., granite, river pebbles, limestone etc.).
Next, customers need to specify the desired finished product requirements, including fineness modulus and particle shape.
Then, based on the required production capacity (e.g., tons per hour), different models can be recommended—for example, a shaping sand making machine for higher output, or equipment tailored for ordinary or specialized mortar production depending on the application.
Finally, customers can select and customize the equipment based on site conditions, installation environment, energy consumption, maintenance costs, and overall project budget.
What certification standards do the machines comply with?
Our equipment complies with international standards, including ISO 9001 quality management certification，ISO 14001 – Environmental Management System. Third-party inspections, such as SGS reports, can be arranged based on specific customer requirements.
What are the available payment methods and Incoterms ?
We accept multiple payment methods, including T/T, L/C, and others as agreed upon in the contract. The Incoterms accepted are generally FOB,CFR,CIF,DAP,and also depending on the terms specified in the contract.
