The experiment presented here has been carried out within the context of a partnership research contract signed between the Road Directorate (French Ministry of Civil Equipment) and the GTM Construction Company. The autors are thanking both partners, and the following organizations or companies, which contributed with equal success to the...
On the Use of Perious Cement Concrete for Wearing Courses and Its Efficiency Against the Noise Emitted by Heavy Trucks
Use of Superplasticized Fiber Reinforced Concrete in the Construction of Pavements
Fibre Reinforced Concrete (FRC) by itself has opened up a new era in the field of Civil Engineering. FRC has given altogether a new dimension to concrete technology. It is even difficult to imagine that just the addition of fibres into concrete mass can change the entire properties of concrete....
Pharmaceutical Waste
Studies are being carried out on the influence of pharmaceutical waste at the Ukrainian University of Transportation, a especially the liquid waste on the physicomechanical 3roperties of cement concrete
Fundamental Study on Bonded Ultrathin Whitetopping
Ultra thin white topping is a rehabilitation technique in which thin concrete overlay is placed on asphalt pavement in distress, and this work technique has been under research in Europe, USA and other countries. In this study, a small model experiment was conducted to see its applicability to the roads...
Fibre Reinforced Concrete Roads Surfaced with Concrete Paving Stones
The paper describes enhanced specifications for concrete block roads suitable for heavy channelised traffic in city centres. It describes two case studies and shows how bedding sand and fibre reinforced concrete roadbases can be specified to ensure zero rutting and a cost effective solution.
Recycling with Cement on the Motorway Salzburg-Vienna
A recycling concept has been used since 1991 for reconstructing 120 km of carriageway on the concrete motorway Salzburg - Vienna: The old concrete is crushed and the coarse material used as the aggregate for the new concrete pavement. The fine fraction is added to the old granular subbase thus...
Processes of Structure Formation and Properties of Cement Stone with Polymer Additives and Disperse Reinforcement for the Repairs of Road Pavements
The addition of special polymer additives and dispersc reinforcement can improve the physicomechanical properties of cement stone being used in road construction.
Use of Crack and Seat in Concrete Pavement Rehabilitation a Case Study
This paper describes the processes carried out in the crack and seat of an existing concrete pavement on the M40 Motorway in England.
The Use of Crushed Concrete Aggregate in Concrete for An Industrial Road at Ouffet
In standard specifications 300 of 1994 (CCT 300) issued by the Ministry of the Walloon Region, permission is granted in the chapter dealing with cement concrete surfaces of roads belonging to roads with light traffic, to replace a maximum of 50 % of the granulates with crushed stones. The aim...
Prediction of Soil-Cement Strength Gain
Prediction of the strength gain of soil - cement mixtures to be used as base or sub-base of roads is of practical importance. It is necessary to know with good approximation the strength developed under the 'in-Situ' curing conditions for a given age. This research work has studied the application...
Non-Clinker Slag Binder
The solution of questions of using slag as a binder material vit1i different catalysts is highly actual, since it helps in broadening the nomenclature of binder materials. increases qualth' and durability of products containing these stags. Ecological problems of regions vitIi developed metallurgical industries are solved as well.
Thin White Topping in Vienna
Conventional maintenance of rutted asphalt roads means resurfacing in short intervals or substitution of thick layers. Therefore, a new repair method was tested: Milling the top of the existing asphalt pavement, cleaning the surface and plaeing a dan layci of high performance concrete. The behaviour of the composite structure was...
