Article
This paper presents a field study showing the distribution of air voids in asphalt layers, and the potential effect of water on pavement performance. The paper also discusses the applicability of the European test method and equipment for assessing permeability of asphalt layers. A series of laboratory permeability tests were conducted on in-situ c...

Abstract The focus on the construction of new roads will certainly face a shift to the widening, maintenance and strengthening of the existing roads and pavements. However, the Hungarian stand- ard referring to asphalt pavement and overlay design is out- dated in many ways, and to efficiently use national resources a proper analytical design mus...
Article
The paper addresses the determination of a stiffness-temperature correction model for the use in a mechanistic overlay design method, developed at the Department of Highway and Railway Engineering, Budapest University of Technology and Economics. Eleven models are selected and evaluated based on 215 laboratory stiffness test results at various temp...

Asphalt industry finds itself battling ongoing economic difficulties and an urge to achieve a more sustainable development and growth. It means constant searching is needed for alternative materials and possibilities to use recycled and processed waste materials in asphalt mixes as long as an expected level of performance and durability is provided...
Article
The load equivalency factors for pavement design currently in use by the Hungarian standard have been developed using Weigh-in-Motion data obtained during the first few years of operations after installing some 30 measuring sites in Hungary in 1996. In the past years, and currently, data is collected mainly at the border crossings of the country, h...

However, the Hungarian standardreferring to asphalt pavement and overlay design is outdatedin many ways, and to efficiently use national resources aproper analytical design must be urgently develop...
Conference Paper
Full-text available
The current Hungarian overlay design manual was developed in the 1990s and no major review has been conducted since then. Therefore the technological and material advances e.g. modified binders and mixes, high modulus mixes, use of reclaimed asphalt pavements, asphalt grids and nets, compromises with local resources, changes in traffic loading and...
Conference Paper
Full-text available
The current Hungarian pavement overlay design method is outdated in respect of considering techniques that are already commonly used. In this paper we present the summary of a mechanical approach of overlay design currently under development at the Budapest University of Technology and Economics, Department of Highway and Railway Engineering. The s...

Full-text available
The use of crumb rubber from vehicle tyres in hot mix asphalt production has been a very promising option in the field of waste recycling and sustainability. The disposal of used vehicle tyres has been a serious and difficult issue. Due to their indestructible nature the options are burning or disposal, none of these are desirable in our global env...

the trade-off regarding stiffness and low-temperature behaviour of hot mix asphalt (HmA) mixes is well known – the higher the stiffness of an asphalt mix is, the lower its relaxation during fast cooling down in winter, resulting in thermal cracking at higher winter temperatures. the accumulated tensile stress together with the stress deriving from...
