Abstract: The performance of road and airport wearing courses does not depend only on their bearing capacity. Many of the properties and characteristics of a pavement, such as its friction, drainability, and acoustic absorption, ...

Abstract: The performance of railway tracks can be assessed by separately applying different approaches, such as reliability, availability, maintainability, and safety (RAMS) and lifecycle costing (LCC). Results of these approaches ...

Abstract: The main objective of this research is the formalization of strategies and technical procedures for recycling porous European mixes (PEMs) back to permeable wearing courses. A number of issues were studied: mitigating the ...

Abstract: Bituminous mixtures with low nominal maximum aggregate size, NMAS, have appreciable acoustic performance. Their surface texture is crucial to balance acoustic- and safety-related requirements. Unfortunately, there is a ...

Abstract: Assessing the volumetrics of hot-mix asphalts (HMAs) is an important aspect of quality-control and quality-assurance procedures. The economic value of HMAs is usually assessed in terms of their mix bulk specific gravity (

Abstract: Acceptance procedures are usually defined in terms of the fraction of elements that fall outside certain specification limits, such as the data dispersion around a central tendency. In contrast, design methods usually ...

Abstract: Quality control/quality assurance tests can be used to demonstrate that an as-constructed pavement has characteristics different from the contracted specifications of the as-designed pavement because the bitumen employed ...

Abstract: Road safety builds on traffic and driver–infrastructure interaction: nighttime visibility represents a key-aspect of this complex interaction. Therefore, providing an adequate road lighting system and improving drivers’ ...

Abstract: Specifications limits and tolerances are crucial in the relationships among contractor, road agency, and citizens because they influence profits, acceptance procedures, and pavement durability. They mainly depend on processes ...
