Construction of Cement Concrete Pavement on National Highways started in India during the year 1991 when Ministry of Surface Transport, Government of India, under took four laning of 112 Kms. long Delhi – Mathura Section of NH-2. Construction of Cement Concrete Pavement picked up in 1998 with the implementation of...

Since 2001 the design with an interlayer of geotextiles is a standard structure in the German pavement catalogue RStO 01. Geotextiles shall guarantee uniform, elastic support of the concrete slab, hence reducing stresses due to temperature and moisture gradient, reduce pumping processes and prevent an origination of reflection cracks from...

The design period of pavements in Austria is in general defined with 20 to 30 years. According to the Austrian standards and guidelines for pavement design the design life for bituminous roads is 20 and for concrete roads is 30 years. Looking at existing roads, it can be recognized that...

The European Long-Life Pavement Group (ELLPAG) was formed in 2000 as a working group by the Forum of European National Highway Research Laboratories (FEHRL) members, under the auspices of the Conference of European Directors, to report the current state of knowledge on long-life pavements in Europe, in particular on the...

Concrete road surfaces with useful properties and a long useful life have been constructed for many decades, but further development is still required due to changing boundary conditions. Here, the important challenges are the increase in traffic load as well as specific requirements to traffic safety, environmental compatibility and economic...

In recent years, a new material has been experimented in Italy for road pavement foundations. It is a mixture made of Waste Foundry Sand (WFS) and Construction and Demolition (C&D) aggregate, water and CEM 32.5R cement, the performances of which can be compared to those of traditional cement bound granular...

The paper presents the analysis of the numerical model of airport slab and foundation under thermal loading. Various types of constrain (unilateral and bilateral) between slab and foundation have been taken into consideration. Numerical data has been compared with experimental results, concerning vertical displacements of airfield plate subjected to the...

The precision and applicability of two non-destructive measuring methods for dowel bars alignment: • Ground Penetrating Radar (GPR) and the • Pulse Induction method (PI). was investigated. The project was sponsored by the German Federal Ministry of Transport, Building and Urban Affairs (Bundesministerium für Verkehr, Bau und Stadtentwicklung BMVBS). The...

The aim of this paper is to present an overview of the construction of a continuously reinforced concrete inlay at the compulsory truck stop on an interstate freeway: National Route 3, Section 3, km 20.0. The truck stop is situated in a truck lane on the southbound carriageway of the...

The Guided Busway Design Handbook, produced in 2004 and the Guided Busway Construction Handbook (2006) are best practice guides to guideway construction. This paper describes development of the handbooks which drew on experience from across industry and lessons learnt from previous projects. Ongoing work since publication of the handbooks to...

The Netherlands has made a clear decision to increase traffic mobility by reducing the use of traffic lights wherever possible. If traffic lights are not to be used, crossings need to be changed. The easiest solution is to change crossings into roundabouts and this solution (depending of the volume of...

Some concrete roads have been constructed and finished or textured that lead to an unfavourable texture. This kind of textures can lead to unacceptable high noise levels. However, from the civilengineering point of view these roads can be very durable. In those cases, only the surface needs a treatment to...
