Roller concrete has been adopted from dam-building technology, where it is used as a rapidly constructed and durable solid concrete. In road construction, roller compacted concrete is predominantly used in foundations, as a supporting layer. For surfacing or as a layer of surfacing. Some applications in Belgium are discussed. This...
Abrasion Resistance of Concrete Pavements
The property of abrasion resistance is the ability of a material to resist mechanical abrasion. This paper deals with different test methods, especially road wear simulators, requirements and influencing factors for wearresistant road surfacing concrete. The average annual daily traffic (ADT) adjusted for the proportion of traffic with studded tyres,...
The Concrete Pavements in the Mexican Highways
In Mexico, since november of 1993 to september of 2002, a total of 3046 km of concrete pavement lanes are either in operation or construction, where 74% of them are built as new structure and the rest, 26 % has been used as reinforcement placed on an existing aphalt pavement....
CRCP A Long-Lasting Pavement Solution For Todays Motorways, the Dutch Practice
Continuously reinforced concrete pavement (CRCP) structures are becoming more popular for high quality transport purposes and long lasting pavement solutions in The Netherlands. This increase raised the demand for practical guidelines, recommendations and standardisation with respect to design, construction details, the preparation of tender documents and construction. Up to now...
Flexural Stress Analysis of Rigid Pavements Using Nisa
Design of pavements involves a study of paving materials their behavior under loads, climatic conditions & the under lying sub grade reaction. For the present study an attempt has been made to propose an alternative method of design of rigid pavements using NISA package. 2-D plane strain and axisymmetric solid...
Frost Damage Prevention of Concrete Pavement
Due to severe frost damage at the main platform on a military transportation airfield in the Netherlands, investigations have been carried out to find the course of this damage. Tests have been carried out to compare the frost sensitivity of Portland cement and Fly-ash cement. Also the influence of several...
The Use of Statistical Experimental Design to Investigate the Autoclave Curing and Standard Curing of Cement
28 day compressive strength of Portland cement mortar was investigated for standard curing and for autoclave curing. The effects of %C3S, %SO3 and Blaine on strength development in both curing methods are compared via the use of statistical experimental design techniques. Box-Behnken response surface methodology was adopted to create a...
Development and Application to the Test Pavements in the Real Way of Eco-Friendly Hybrid Type Permeable Concrete Pavement
A new type of pavement structure was proposed and applied to the construction of two different trunk roads. The hybrid structure is composed of two basic layers of the porous concrete surface course which has sufficient functions of smoothness, skid resistance, permeability and low noise and of the less permeable...
Combustion of Asphalt and Concrete in Case of Fire in Roads
The present study concerns the comparison of the behaviour at high temperature of an asphalt and that of concrete, the purpose being to define the parameters of choice of the material for the construction of roads, in particular in tunnels. To do this, laboratory tests of fire, thermal behaviour and...
Experimental Sections of Ultra-Thin White Topping in Tournai
The technique of ultra-thin white topping, which has been used in the USA since the beginning of the 1990s, is characterised by a thickness of between 5 and 10 cm. They are characterised by a mesh of closely spaced joints in which the distance between the joints depends on the...
Continuously Reinforced Concrete Pavement in a Tunnel in Liege Belgium
In June 2000, a new motorway link (E25-E40) was inaugurated in Liège to solve transit and local traffic problems. It serves more than 65,000 vehicles a day in both directions. With multiple technical, environmental and security-related constraints, the 5 kilometres of this infrastructure prefigure numerous works such as bridges, roads,...
Analysis of Cracking Mechanisms in Concrete Pavements and Related Recommendations For Pavement Construction
In addition to the stresses caused by traffic loads concrete highway pavements may be subjected to considerable stresses due to environmental action effects and other related damaging mechanisms such as early age shrinkage, loss or absorption of moisture, temperature induced strain gradients and in some instances also alkali-silicareactions. Due to...
