Characterisation of Cold Asphalt Mixtures with the Addition of Active Fillers
(2023)
Climate change, the limited availability of natural resources, and energy crises are putting pressure on the global societies? to employ low-energy and low-emission technologies for road pavement construction. Cold Recycled Materials (CRM) is an efficient and low-impact solution. CRM with Bituminous Emulsion (CRM-BE) is one of the most common types of CRM. CRM-BEs are created at ambient temperature by combining a high amount of Reclaimed Asphalt (RA) with Bitumen Emulsion (BE). BE used in CRM is typically composed ...

Evaluation of Bitumen-Aggregate Adhesion Bond Based on Surface Free Energy and Comparison with Moisture Sensitivity and Asphalt Performance Tests
(2024)
The adhesion bond between aggregate particles and bitumen plays a crucial role in ensuring the durability of asphalt pavement, and it is influenced by factors such as bitumen-aggregate compatibility, moisture exposure, other environmental conditions, and traffic loads. Failure of the adhesion bond results in the detachment of bitumen from the aggregate surface and leads to stripping in the presence of moisture. This, in turn, leads to the development of macro cracks and disintegration within the asphalt pavement, ...

Design of flexible pavements with cold recycled asphalt bases: Comparison of five national approaches
(2020)
The Application of reclaimed asphalt is becoming increasingly important in the European Road Network. Beside the conventional recycling options (i. e. hot asphalt mixtures), cold recycling has been successfully applied in numerous road structures within the secondary and the main road network. However, the standard design procedures for common pavement materials as well as the approaches for cold recycling differ from one country to another. The comparison of five national pavement design procedures shows, that ...
