Since 1985 more and more elastomer prnfiles MA iiced for longitudinal and transverse joints of German highways to get a watertight filler between the concrete slabs. Specially designed highway profiles are compression seals that can be installed even under wet and cold weather conditions. They can follow very large joint...
Status of a Five Year Old 170 mm Thick Jointed High Strength Concrete Pavement in Norway
The current pavement is a 8.6 km long part of the main highway North of Oslo. The concrete has a characteristic cube strength of 90MPa and the slab thickness is 170 mm. The subbase mainly consists of local natural sand and gravel. The general condition of the pavement is rather...
Noise Reducing Techniques on Existing Continuously Reinforced Concrete Pavements on Belgian Motorways
Most of the Belgian Motorways, with a concrete pavement, have a deeply grooved concrete surface. Although those wearing courses have a very good skid resistance, there is a great concern about the noise pollution. Not only noise barriers and the porous asphalt overlay, but recently also the grinding are an...
Pavement Design and Behaviour Heavily Trafficked Concrete Carriageways in the Seventies
In order to update pavement structure designing methods, the French Technical Network, SETRA (Roads and Highways Engineering Department) and LCPC (Central Public Works Laboratory) have used the LCPC road structure circular test track to study fatigue phenomena relating to several concrete pavement structures and to compare them with the "Californian...
Swedish Experience with and Recommendations for Thin Concrete Overlays on Old Concrete Roads
This paper describes the Swedish experience with thin concrete overlays on old rutted concrete roads. In Sweden, the use of studded tyres leads to wedi and rutting on highways with intensive traffic. In the late seventies, some concrete roads were built in the South of Sweden. A thin concrete overlay...
Reconstruction of Low Volume Roads in Austria Using Cement Stabilization Mixed in Place
In view of the growing need for economic methods for rural road rehabilitation and reconstruction the use of cement stabilization mixed in place with existing pavement materials (recycling of milled material) is considered to be an economic and resource-saving approach. This paper describes the preparatory works required (inspection of the...
Construction of Concrete Pavements on Bituminous Draining Bases
In January 1 9a9 1ro, ad section of 12 km, the access to Zaragoza from Huesca (Spain), was opened to the traffic. Works presented two main technical singularities in Spanish road design and construction. The first one was the introduction in Spain of the construction of rigid pavements on bituminous...
Development of a Roller Compacted Concrete Pavement Reinforced with Continuous Steel Bars
A roller compacted concrete pavement (RCCP) reinforced with continuous steel bars was recently developed at the New Tokyo International Airport. The construction is fast and the effectiveness of load transfer at cracked sections of the continuously reinforced concrete pavement is high. This RCCP was built in two layers. Steel bars...
Technique to Create Wear Resistant Concrete
Through expericnccs during the last years we have gained knowledge about the decisive factors to obtain a wear resistant concrete pavement. The most important factors are: the quality of the aggregate, the strength of the concrete, the adhesiveness between the cement paste and the aggregate particles, the maximum size of...
The Significance of Grain Size Distribution for the Behaviour of High Strength Concrete for Road Purposes
In the last years high strength concrete has been used more and more frequently for road construction in Norway. To obtain good abrasion properties and a good wurkaL,ility the quality of the coorco oggrogateE and the ovrall grain qi7 ,9 distribution is very important. By improving the abrasion properties it...
Surface Characteristics of a Recently Constructed Concrete Motorway in the UK
A full-scale trial has been constructed in the UK in which concrete surfaces with brushed, tined bnd exposed aggregate textures have been compared with traditional hot rolled asphalt. The concrete surfaces were applied to a 250 mm thick, continuously reinforced concrete pavement laid by railmounted paving equipment. The exposed aggregate...
Some Aspects of the Construction of the Azraq to Jafr Highway Project in Jordan
Hot desert environments with low humidity and strong winds provide some of the most difficult conditions in which to build good concrete roads. This paper briefly describes the materials, plant and some of the methods that were used to successfully construct the Azraq to Jafr highway in Jordan where these...
