Based on a literature search, several types of fatigue relationships were collected, compared and analysed for plain concrete (specimens, pavements) subjected to repeated loading. A uniform fatigue relation - based on the FS- R concept - has been proposed for the flexural tensile strength. The 50%-probability curves have been analytically...
A Design Method of Composite Pavement with Asphalt Surface Course and Continuously Reinforced Concrete Base Course
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...
Consideration of Some Factors Affecting the Competitiveness and Potential for Future Use of Concrete Roads in the UK
Although concrete roads have traditionally been used in the construction of a small part of the UK network, there is continuing interest in the potential for concrete pavements. Consideration of the way in which whole life cost (WLC) may influence selection of the most competitive form of concrete structure when...
Revision of the Austrian Design Method for Standardised Concrete Pavements
The Austrian specification for pavement design also contains standardised construction types for concrete roads. After more than 10 years of experience with the application of these standard pavement types the specification has been revised comprehensively with a special focus on the following objectives: - establishment of an improved method for...
Study on Quality Control Method for Road Pavement Concrete Using Splitting Strength
The quality control of pavement concrete is carried out with bending strength in Japan. However, the bending strength test requires very heavy specimens of 15xl5x53cm and it is not easy to cariy out loading tests. This paper shows the results of several experiments on the feasibility of using the splitting...
Computational Modelling in the Theory of Concrete Pavements
The jointed concrete pavement is analysed as a system of interacting rectangular slabs transferring wheel loads into an elastic layered subgrade. The finite element plate analysis is combined with the assumption of a linear contact stress variation over triangular elements of the contact region division. The linking forces are introduced...
Experimental and Numerical Study of Behaviour of Concrete Pavements
The numerical methods are a fundamental tool in the analysis of concrete pavements. However, the numerical methods need experimental data in order to calibrate the model parameters. This means that only the use of both techniques, experimental and numerical, allows an efficient simulation of the behaviour of pavements. Therefore, a...
Pavement Design Procedures for New Construction and Rehabilitation with Overlay
The first part of the paper deals with the designing of rigid pavements by means of FEM. The NE10-SOILIN program uses the NE-10 finite elements composed of subelement 2D NE-10-M (tetragonal element), subelement 3D NE-I013RJCK and subsoil element. It models the Midlins slab placed on a generally multilayer structure. Under...
Standard Designs for Concrete Roads
A manual on standard pavement design has recently been presented in The Netherlands. This manual deals with various types of roads constructed in plain concrete, composed as Publication no. 120 under the auspices of CROW (CROW = Centre for Research and Contract Standardization in Civil and Traffic Engineering). The manual...
The Shrinkage Model in the Non-Linear Fem Program Parma for the Design of Reinforced Concrete Pavements
The design of reinforced concrete pavements presents complex problems of modelling, owing to the marked nonlinearity of structural response of the reinforced concrete, of the foundation and the unilateral behaviour of the interaction between pavement and foundation. The external actions to which a road pavement is subjected are the result...
Concrete Pavement on a Crushed Aggregate Unbound Roadbase a New Design for Heavy Traffic Motorways
The construction method involving the placement of a 30 cm-thick concrete roadway pavement on a 30 cm-thick crushed aggregate unbound roadbase instead of a 2.6 cm-thick concrete pavement on a bound roadbase has proved its worth in Germany for more than 10 years, generally for heavy-traffic motorways. It has several...
New Standard Design for Concrete Roads in Flanders (Belgium)
This paper describes the new pavement design catalogue for concrete roads in Flanders. The catalogue includes plain concrete and continuous reinforced concrete pavement. Structures for interlocking concrete block pavements were added. The catalogue contains structures for roads as well as for bicycle lanes. The structures are based on the concept...
