Continuously Reinforced Concrete Inlay at Townhill Compulsory Truck Stop

Highways Members Only

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...

European Long-Life Rigid Pavement

Highways Members Only

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 with Exposed Aggregates – Experiences in Germany

Highways Members Only

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...

Mechanical Characterisation of Cement Bound Mixtures with Waste Foundry Sand and C&D Aggregate for Road Pavement Foundations

Highways Members Only

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...

Numerical Model of Airport Slab under Thermal Loading

Highways Members Only

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...

Reclaimed Porous Asphalt Pavement Used as Aggregate in Cement Bound Concrete Pavement

Highways Members Only

In the Netherlands reclaimed asphalt pavement is normally used as cold aggregate to produce recycled hot asphalt mixtures. However reclaimed asphalt pavement originating from porous asphalt pavement can not be used in this process. Therefore it would be valuable if these residual aggregates could be used in concrete production. A...

Rapid Hardening Fiber Concrete for Airport Pavement Repair

Airports Members Only

Repair of concrete airstrips is a matter of particular interest. Besides being costly, it obstructs airport operations. Consequently, materials and construction procedures must comply with technical and operational demands. This article describes the development and application of a cementitious rapid hardening binder and a corresponding polymer fiber concrete for the...

Guidelines for the Design and Construction of Kerb-Guided Busway Infrastructure in the UK

Highways Members Only

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...

Design Philosophy of a Concrete Bone Roundabout (CBR)

Highways Members Only

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...

New Technique for Silencing Existing Concrete Roads

Highways Members Only

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...

Prestressed Concrete Pavements

Highways Members Only

In this paper the results of laboratory investigation preceding realization of continuous prestressed concrete pavement at Krakow – Balice Airport are presented. Three concrete slabs of dimentions 1.0 m × 3.6 m × 0.16 m were realized in the Laboratory of Technological University of Krakow. Two of them were prestressed...

Decision Support Model for Road Pavements Based on Whole Life Costing, Life Cycle Analysis and Multi-Criteria Analysis

Highways Members Only

In response to the growing importance of sustainable building, designers, consultants and pavement managers now tend to make more rational decisions than before when comparing the pros and cons of the construction, maintenance and management of various types of road pavements. Asphalt and concrete pavements offer specific advantages that need...
