Mix-in-Place Recycling with cement stabilization is an economical and environmentally friendly method for the reconstruction of damaged asphalt roads and ways. The most remarkable characteristic of this method is that the entire existing road construction material can be used again for the new road pavement. This essay contains descriptions of...
Reconstruction of Bituminous Paved Rural and Urban Roads in the Federal Republic of Germany Using Mix-In-Place Recycling with Cement
Influence of Fly Ash on Abrasion Resistance of Concrete for Roads Pavements
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...
Roughness Condition and Rule Quality of Bicycle Lanes
The Netherlands are a flat country, where the bicycle is a good alternative for short and midrange transportation. The government tries to encourage the use of a bicycle by improving the bicycle infrastructure, thus trying to reduce movements by car. Bicycle pavements are managed at a local or county level....
Verification of the Acting of the Recycled Building Material for the Production of Rigid Pavements in Concrete of Portland Cement
The objective of the present work is the study of the technical viability of the use of refused material of building construction like aggregates for concrete roads. The first stage consisted of the physical characterization of the aggregates obtained through the grinding, followed by a study of the granulometric composition...
Eco-Concrete Block Paving
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...
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...
Roughness and Ride Quality of Airport Pavements
This paper describes a method for routinely evaluating airfield pavement surface roughness from an aircraft ride quality perspective. The method is designed to be as compatible as practical with existing pavement management system data collection and reporting processes. Ride quality has always been recognized as a major factor in a...
Reconstruction and Recycling of Concrete Pavements
After 30 to 35 years heavy traffic loading concrete motorways have to be reconstructed. In Germany, the old concrete pavement was ]ft in its place and overlaid with a new pavement. This reconstruction method may be really economical under definite circumstances but is hardly practicable for the contemporary reconstructions, especially...
The Influence of Friction Between Layers on Surface Deflections of Rigid Composite Pavement Structures
The paper presents the influence of friction between layers on surface detlections of rigid composite pavement structures. Pavement structures were analysed using BISAR Programme and non- destructive testing technique under different bonding conditions between the asphalt and the concrete layers. The analysis of the data involves the use of hack-calculation...
Test Sections of Noiseless Cement Concrete Pavements
Halfway through 1996, six different wearing courses were casted over a length of 3 km on the N255 Edingeri-Ninovc at Ilcrnc and Gaimaarden. 4 Different wearing courses each 4 cm thick, were casted on a continuously reinforced concrete pavement. In addition to the conventional wearing courses SMA 0/14 and ZOAB...
Reuse of Alkali Damaged Road Concrete in Cement Bound Road Bases
Aggregates were obtained from an alkali-silica damaged concrete road slab aggregates and used for road base concrete with different kinds of cement (low alkali cement, high alkali cement). After analysing the samples produced with these mixes, which were exposed for up to one year to different hardening conditions, no alkali-silika...
Wear Resistant and Noise Reducing Concrete for Road Pavements
Rutting, depending on the wear of studded tyres, is a problem in the Skandinavian couritiis. Concrete pavements have a good wear resistance. In Ai.ustria they have recently developed a low noise concrete with small aggregate size and exposed aggregate. Earlier experiences have shown that the wear resistance of concrete is...
