ECOPAVE is a system of laying concrete through a modified bituminous paver, inducing transverse cracks into the concrete, and overlaying with a thin bituminous surfacing. The system has been developed through a BRITE project with partners in the UK and Denmark. It is coiisideied to provide economic benefits over the...

Laboratory tests have been carried out to examine the effect of the following parameters on the erosion behaviour in the case of cement treated subbases (CTB) below concrete pavements: aggregate mixture (gravel or sand), treatment (with wet treatment, without treatment), compressive strength requirement (varying cement content), arrangement of a geotextile...

The research on RCCP was launched in early 80' in China. The laboratory test started in 1981 followed by the first sectioii of field experimcnt road in 1982. And then extended resmrch was carried out in 1983 and 1984. A few years later in 1988, the research on Cement Concrete...

This paper describes a new design of joints in rigid pavement, in this case the angle between joints will be 120 grades in anypoint of the pavement between edges. This new concept about corners angle,change the original work of Westergaard for the "corner load",because it only considerate angles with 90...

is important to have the knowledge about the connections between different costs and different surface characteristics of a pavement. The costs are for the road, traffic safety, road user and environment etc. The surface characteristics are things like friction, micro- and macro structure, iuts, evenness, cracks, sloping and drainage etc....

The paper describes and evaluates plate hearing tests performed on airfield CC slabs, in order to ascertain the interaction of slabs across transverse and longitudinal joints and the joint load transfer. The applied characteristics of mad transfer I .T and T ,TF, varied, however. the great significance of temperature and...

The present paper aims to contribute to the study of the structural response of concrete slabs jointed by dowel bars in pavements. As is known, a common construction technique of pavements is this one that uses concrete slabs interconnected each other in both directions by equidistant dowel steel bars. A...

This article describes the behaviour after 17 years of service of the test sections constructed in 1979 on State road N 4 in the Belgian province of Namur. The object of this experiment, is to compare various types of contraction joint on the same site and under the same conditions...

The Spectral-Analysis-of-Surface-Waves (SASW) method is a non-destructive seismic method which has been used in situ to determine the elastic moduli of soils and pavements at low level of strain and the variation of these moduli with depth. The test is based on the dispersion of Rayleigh-waves which means that Rayleigh...

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...

The work was undertaken by contractors Ooms Avenhorn. Work took place in the months of July, August, September and October 1995. The roundabout was opened for traffic on 6I October 1995 (photo 6). More than two years after opening of the roundabout and the road metalling associated with it, it...

In the quest for introducing materials and techniques of construction, the Research & Development Division of the Road Development Authority, Sri Lanka has carried out several trials and successfully constructed an airport apron, a causeway of 2km length using Roller Compacted Concrete (RCC) pavements and a road of length 0.265km....
