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 Concrete Block Pavements
In recent years several investigations were carried out in Germany aimed at reducing the tyre-road noise on concrete block pavements. The results show that these pavements can be constructed with a surface producing the same low traffic noise level as the reference asphalt road surface. In the paper, conclusions are...

Moisture Effects on the Bahaviour of PCC Pavements
Results of immersion-drying laboratory lest on pavement con-crete pieces show that tbe deformations produced by internalmoisture variations are as important as those produced bytemperature changes. Indirect measurements of internal mois-ture in actual pavements demonstrate the predominant existenceof a moisture differential between the slab surface and bottom.The resulting upward warping in...
The Road Retreatment Plant Arc 700
The retreatment of old cement pavement is an old technique hat needed rustic equipment coming from agricultural equip-nent or very often meant for the stabilisation in place of fine.oils.faking into account the scatter of measuring out of Portland:ement, the lack of power and efficiency of the mixing equip-nent, this technique...
Road Surfaces Roughness by Shotblasting
According to the findings made on French road network about .helow skidding resistance, GAILLEDRAT Pére & Fils com-rany developed a new surface treatment concept: THE SUR-:;'ACESHOTBLASTING.l'his technique which allows to treat most of the slippery road.urface problems on asphalt or concrete pavements. permits toncrease the surface roughness "as requested" and...
Design Charts For Small Element Precast Concrete Slab Pavements Using a Combined Finite Element Westergaard Approach
Small element precast concrete slab pavements through their use in urban areas where vehicular over-run is predominant have suffered severe failures which incurred a substantial public expenditure for their maintenance in the UK. This has created a need for the development of a rational design method that would lead to...
Evaluation of Existing Pavements and Conçrete Overlay Design in the Netherlands
Working Committee «Overlay in concrete» is founded to create a manual containing practical methods for designing and building concrete overlays for road and airport pavements for Dutch conditions. Results of the Working Committee activities are presented in this paper. A method to determine the bearing capacity of existing pavements is...
Practical Rehabilitation Options For an Aar Affected Jointed Concrete Pavement
As a result of fine cracks that initiated in the vicinity of the joints of an unreinforced jointed concrete pavement, structural failures rapidly developed under traffic. Structural failures manifested as punch outs where severe pumping at wider cracks occured and it was clear that only reconstruction or overlaying could be...
