Opening concrete pavements to traffic the day after placing has been a routine practice in Vienna for many years, but increasing traffic requires even shorter closure times. On motorways even a single lane can be closed to traffic only at night or at weekends. With a w/c of 0,35 and...

In 1996, the Florida Department of Transportation (FDOT) started a research project to evaluate design, construction and performance of the ultra-thin whitetopping on asphalt pavements. Three UTW test tracks were constructed at the FDOT research facility in Gainesville, Florida. The design of the UTW test tracks included thicknesses ranging from...

This report details the construction of a 300 m long experimental section of road for heavy traffic in Villamayor, Salamanca, Spain, using "high performance porous concrete" (HPPC). HPPC is made with the same materials as conventional compact concrete (Ccc), i.e. cement (two types have been used for this project), coarse...

In 1981 to 1985 and 1993/94 static and dynamic tests on block pavements were carried out on a 1:1 scale at the professorship of Road Construction at the Technical University of Dresden. The pavements were loaded with a plate bearing test equipment (approx. 0.7 N/mm 2) with a static stress...

The construction method involving the placement of a 30 cm-thick concrete roadway pavement on a 30 cm-thick crushed aggregate unbound roadbase instead of a 2.6 cm-thick concrete pavement on a bound roadbase has proved its worth in Germany for more than 10 years, generally for heavy-traffic motorways. It has several...

Continuously Reinforced Concrete (CRC), invented in the United-States in 1921, has been developing in France since 1983, in the following contexts: - New constructions (50 km of motorway) The structures chosen are alternately: • CRC + lean concrete • CRC + bituminous concrete + stabilized capping layer - Strengthening of...

The paper presents the progress to date of various worksites where stabilisation by recycling in situ with cement has been applied. This technique, which is the best way of recycling the existing road, consists in fact in mixing on site cement with the readily available crushed stones. It requires little...

Since 1975, the year in which the first continuous concrete plant was introduced for a road construction project, the use of a continuous production process has become more widespread, and even generalized, in France. Applications in other European countries have started to appear, yet do remain in the nascent stages....

High strength concrete (HSC) having a flexural strength considerably higher than that of ordinary pavement concrete would be a suitable material - to replace only a single lane of concrete pavement deteriorated by heavy duty traffic (see Fig. 1) or - for constructing new pavement for high load with limited...

Deterioration of Bombay Metropolis roads during rainy season is a perpetual phenomenon. During the monsoon of 1988, the major roads constructed with hydrocarbon binders suffered severe damage causing great inconvenience to the users. In view of the mounting pressure from the public, at large the municipal authorities decided to switch...

In order to harmonize FWD condition surveys on concretee pavements in the Netherlands, CROW's committee UEC1 has developed an structural evaluation procedure for jointed concrete airfield pavements. The committee has developed procedures for in-situ testing and models for determining of the mechanical pavement properties based on FWD measurements. With respect...

Calculation of steel-concrete structures calls for understanding the bonding mechanisms, then, to reproduce them, formulating models of behaviour representative of the interface between the two materials in contact. In view of the researches already performed in this domain, we thought it essential to make use of a new test that...
