Decentralization has brought about significantly renewed interest in France in investments for regional and local roads, their rehabilitation and maintenance. Many methodological tools have been developed in the past 10 years to prepare and accompany these trends in areas in which cement concrete had played a sinall relative part in...

lIn Norway, most every car is equipped with tires having small steel studs to improve the friction between the tire and road during the winter season. These studded tires have an enormous wearing effect on ordinary asphalt pavement.

The layout commonly used at major motorway sites in the United Kingdom is the full contra-flow, which carries two traffic lanes in each direction on one carriageway, releasing the other carriageway for reconstruction. To improve operational efficiency, two adaptations of this layout, which operate with a reversible (or tidal) lane,...

The first Ree full scale testing project in Norway took place in 1981. Since then appr. 260.000 m2 Ree have been placed. The use of Ree in roads in Norway has been directed by the following main principles: 1. Ree shall be a pavement with good bearing capacity, good resistance...

A series of tests have been carried out to figure out the in-fluence of deviation of the dowels on concrete paving slabdowels with respect to slab movements through shrinking andthermal variations.The stresses produced in the slabs for various deviations withrespect to the theoretical position and according to the systemchosen to...

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...

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...

This work reports the results obtained with the three point bend tests (TPBT) carried out on beams made up of the concrete used for the construction of a by-pass highway and, by comparison, of medium (50 N/mm2) and high strength (98 N/mm 2) laboratory concretes. Typical parameters of fracture mechanics,...

The Illinois interstate highway network includes over 1700 centerline miles of jointed concrete and continuously reinforced concrete pavements. The pavements were constructed beginning in the 1950's through the 1980's and represent a wide range in designs and traffic loadings. This large highway network is now requiring extensive rehabilitation work as...

Generally due to an unsufficient vibration, the concrete around the construction joints may contain cavities, especially under the reinforcement. When very hot weather conditions prevail, these deficiencies may cause important deteriorations, possibly with mere fragmentation of the concrete around the joint. As there are over 5.000 construction joints on the...

The rehabilitation of portland cement concrete (PCC) pavements on high volume freeways have always posed a challenge. In the summer of 1989, the Ministry of Transportation of the Province of Ontario (MTO), Canada, accepted the unique challenge to rehabilitate one such freeway using various PCC pavement repair techniques in one...

Roller Compacted Concrete Pavements have been constructed on six US Forces military installations within the Federal Republic of Germany (FRG). These RCC pavements will be used as hardstands supporting either wheeled or tracked vehicles. RCC hardstands within the FRG have saved as much as 22 % of the construction cost...
