This paper attempts an actual analysis of the cycle cost of urban pavements through the discussion of a case study: the City of Buenos Aires, Argentina. Three frequent paving solutions for the local street system are compared: plain concrete and two different asphalt alternatives. Construction, maintenance, reconstruction as well as...
Mechanistic Evaluation of Spalling Distress
In this paper, delamination formation is investigated. Stresses due to temperature and moisture variation are considered within the scope of the formation of the delamination. Tensile and shear stresses are determined numerically based on finite element analysis using simulated pavement moisture data. A finite element program is developed to allow...
Performance of the Ecopave System After Five Years Trafficking
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...
Erosion of Cement Treated Subbases Below Concrete Pavements
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 Actuality & Prospect of RCCP in China
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...
New Joints in Rigid Pavement – Highway and Airport
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...
Whole Life Costing
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....
Joint Load Transfer Testing
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...
Analysis of the Response of Concrete Pavement Slabs Jointed by Dowel Bars
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...
The Namur Test Road Behavior of Various Types of Contraction Joints After 17 Years of Traffic
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...
Non-Destructive Evaluation of a Reinforced Concrete Road by the SASW Method
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...
Concreting Bombay Metropolis Roads in India
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...
