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 experimental continuously reinforced concrete (C. R. C. P.) road section has been realized in 1975 on a Romanian principal road, in a mountain area. There are presented the design method, the materials, the technology and the behavior after twenty years of traffic.

Due to the ever increasing traffic volumes, the repair of concrete pavements has become one of the most difficult problems. One of the means to help resolve this problem is the use of a high early strength concrete. At the Department of Civil Engineering of the K.U.Leuven a research program...

Field tests have been carried out with thin, high strength concrete overlays (whitetoppings) placed on top of the milled asphalt pavement The aim is to find methods to restore rutted asphalt pavements and iliclease their rutting resistance. The whitetopping was limited to 70 mm. Both plain and steel fibre reinforced...

The evaluation and control of vibrations induced in the environment by the road traffic is a problem of increasing concern mainly in urban areas. Several solutions are under development to define pavement structures capable of absorbing traffic vibrations so to reduce the impact on the environment surrounding the road infrastructure....

Within the scope of a research project different block pavings have been studied under realistic load of a road test machine considering the influence on the resistance to vertical deformations and horizontal displacements.

Eco-concrete block paving is considered to be a significant innovation for environmentally beneficial pavements in residential areas. The objective is to infiltrate rainwater on the spot. The use of permeable concrete block paving is restricted by its bearing capacity and the existing soil. The paper deals with fundamental rules, design...

This paper describes a structural design method developed for composite pavement which is composed of an asphalt surface course (ASC) and a continuously reinforced concrete base course (CRCB). The design method is based on the fatigue analysis of CRCB. In the analysis, loading and thermal stresses in (2RU13 are calculated...

Rollcrete Base - also called Cement-sound Granular Base (CBGB) - is basically a dry material bound by Portland cement, placed using an adapted asphalt paver, and vibrated externally. One of the first applications of rolicrete for the Trans European Motorway project was on the Tarsus - Adana - Gaziantep (TAG)...

The section Brussels-Louvain of the motorway E40 was constructed in 1971 with a pavement in continuous reinforced coticiete fui the tlnee tiaffic lanes and an asphalt pavellielli for the elulergency lane. tue to the increase of heavy traffic, the Flemish Government decided the construction in 1994 of a fourth traffic...

The paper presents the employed materials, including binder (Romanian patent) for the technology of mixing and laying of reinforcement concrete for an existing flexible pavement. After thirteen years of significant traffic (over 1.2 millions 100 kN axles) the pavement behavior is correct, proved by the state of slab margins and...

In Portugal, fly ash is often used as a cement replacement material on concrete for road pavements. The percentages of replacement generally range from about 30% in the top pavement layer up to 50% in the bottom layer. A study was carried out for evaluating to what extent such amounts...
