Partners
MAXRAP brings together leading academic institutions and industrial partners from India and Germany to advance research and innovation in sustainable pavement technologies.
In-Person MAXRAP Workshop 2026 at IIT Madras | 21 September 2026 | Registrations Open | Workshop Flyer
MAXRAP is an Indo-German collaborative research project focused on advancing the sustainable use of reclaimed asphalt pavement (RAP). By integrating advanced material characterisation, innovative processing technologies, and mechanistic pavement engineering, the project aims to establish a scientific framework for maximising RAP utilisation while improving pavement performance, conserving natural resources, and reducing the environmental footprint of road infrastructure.
About MAXRAP
Road infrastructure is one of the largest consumers of natural aggregates and bituminous binders. Reclaimed asphalt pavement (RAP) represents a valuable resource that can significantly reduce the demand for virgin materials; however, maximising its utilisation requires a scientific understanding of material behaviour, processing techniques, and performance. MAXRAP addresses these challenges through an integrated research programme combining advanced characterisation, mechanistic pavement engineering, and industrial-scale processing to enable sustainable pavement recycling.

RAP Processing and Beneficiation
Developing efficient techniques for processing and beneficiating reclaimed asphalt pavement for optimal reuse.
RAP Binder Characterisation
Advanced chemical and rheological characterisation of aged binders from RAP materials.
Binder Modification and Rejuvenation
Exploring sustainable modifiers and rejuvenators to restore aged binder properties.
Recycled Mixture Design
Design frameworks for asphalt mixtures incorporating high RAP contents.
Performance Evaluation
Laboratory and field performance evaluation of recycled asphalt materials and mixtures.
Sustainable Pavement Engineering
Integrating sustainability principles into pavement design and construction practices.
Why MAXRAP?
MAXRAP goes beyond conventional approaches based solely on the percentage of RAP incorporated in asphalt mixtures. The project investigates material recyclability, binder interaction and blending, RAP processing, and the recovery of usable constituent materials. By connecting binder- and mixture-scale characterisation with industrial processing, MAXRAP aims to develop a rational framework for maximising RAP utilisation.
