Moisture damage to bituminous pavement occurs via several mechanisms, and appears in diverse forms such as blistering, stripping, and disaggregation. Blistering is a fulminating phenomenon in which the trapped moisture evaporates and upheaves the pavement surface layer within a few hours as a result of so-called blistering heat. In contrast, stripping and disaggregation are types of internal ch...

Abstract The increasing attention over cold recycling technologies as sustainable paving solutions requires a proper characterisation in terms of complex modulus for supporting the pavement design. Among recycled materials, cement bitumen treated materials (CBTM) benefit from presence both bituminous and cementitious binders. This research aims at characterising CBTM mixtures produced with thre...

The asphalt paver must fulfill a set of basic requirements, from sufficient bearing capacity for the expected loads, stability and good resistance to deformations resulting passage large loads at high temperatures, also securing an impermeable surface that achieves adequate drainage water. Hence, it is necessary search permanently continuously improved materials are resistant influence factors ...

poor adhesion between two successive bituminous layers causes adverse effects on the structural strength of the pavement and develops a numbers of premature failure. to improve the adhesion, it is a general practice to apply a tack coat over an existing or newly constructed bituminous surface before laying another bituminous layer. the main objective of this study is to explore the influence of...

The self-healing capability of bituminous materials has been known for many years. Researches were mostly focused on the self healing behaviour during load repetitions. The tests are either time consuming and/or complex. In this paper, a simple self healing test procedure is presented combining the fracture-healing-re-fracture test (FHR) with morphological observations. A fast displacement spee...

In anticipation of the introduction of high modulus materials in the Swiss standards, a research project has been carried out for the evaluation of these bituminous mixtures. Three full-size test sections were built in a test hall for ALT named Halle-fosse: Two sections with two different high modulus bituminous mixtures (named EME, abbreviation of the French designation of the mixture: Enrobé ...
