Microcracked semi-rigid structures
Under present economic conditions the use of bitumen is being reduced as much as possible. For more than twenty years the application of semi-rigid pavements has revealed the drawbacks but also the advantages of such structures. The chief advantage is their low cost, which can be further reduced if the...
Use of concrete block paving – Constructions in Belgium
Concrete paving blocks are an ideal material for the sufacing of trafficked areas, storage yards and residential roads in urban built-up areas. A number of examples of block pavings installed at Hasselt illustrate how it i~ thereby possible to create a pleasing "street image" which complies wi th the rules...
Determination of slab rocking at the joints of a cement concrete pavement
The amplitude of the deflection at the ends of the slabs at the transverse joints under the passage of a heavy load is an impo.tant c.iterion for assessing the effecciveness of the load transfe. at the joints and for the degree of deterioration of the carriageway. The technique applied at...
Experimental section of railway track on a reinforced concrete continuous slab
In 1975, on the Madrid - Barcelona railway line, an experimental section without ballast was constructed with a view to obtaining a track which would be of sufficiently good quality for use by fast trains while costing less to maintain. The 4,IOO-m-long section was located on a part of the...
Commnon loadbearing effect of concrete pavement and cementbound sub-base
The combined load bearing action of the concrete pavement and the cement-bound sub-base (CRSB) has a favourable effect on the long-cerm behaviour of che road structure in the case of unreinforced concrete road slab construction wichout expansion joints. as has proved effective in Germany: - Because of che roughness of...
Minor roads in concrete
In France, bituminous construction has for decades customarily been used for all kinds of minor roads. There are a great many reasons to explain this tradition. All the same, experiments with concrete have been made year after year, and some day, as a result of further dissemination of information and...
Non-destructive testing of motorway concrete pavements
The standard of serviceability of road pavements can be expressed in terms of safety for the user (skidding res is tance, riding quali ty). For highway managers a standard of structural serviceability is essential for optimizing the initial constructional expenditure and for predicting ~he time schedule for maintenance, strengthening or...
A British Railway Slab Track Project
Paved concrete track (PACT) is a continuously reinforced profiled concrete slab laid by a purposedesigned sLi.pf'o rm paving train on which the rails are continuously supported. This paper traces the development of the system by British Rail and includes a detailed description of the components of the system and the...
Improved jointed concrete pavement designs through field observations
This paper will provide specific recommenda~ions for the improvemen~ of jointed concre~e pavement design practice. Tbe recommendations will be based upon findings from a major nationwide research project recen~ly completed in the USA concerning field observations of pavement performance. A concre~e pavement performance database was established and extensive data collected...
