The paper describes the approach adopted for the design and construction of a continuously reinforced concrete road base (CRCB) pavement for a major trunk road proect in the north-east region of the United Kingdom. The trunk road, known as the South Docks Road, is currently under construction and programmed for...
Design and construction of continuously reinforced concrete composite pavement for the A63 South Docks Road Hull
Slab behaviour of plain undoweled concrete pavements
The behaviour of plain concrete slabs, belonging to pavements with no dowels through transversal Jo~nts, is described. The slab behaviour is observed by means of field instrumentation, measuring absolute deflections produced by environment variations (temperature and moisture), by support rigidity variations and by a controled axle load. Deformations are measured...
Erosion of concrete pavement sub-bases
A special session of the 65th annual meeting of the Transportation Research Board in Washington, in January 1986, brought together some 50 practitioners and research workers on the theme "Erosion of sub-bases; stepping of slabs and pumping of concrete pavements"; ~he presentation of 3 U.S. papers and two French ones...
Road concrete with superplasticizers
Road concrete made with superplasticizers has successfully been used for about ten years now. Its special features with regard to mix composition and method of placing were reported in detail at the London symposium in 1982. This method of construction is increasingly being applied in Austria: - For the maintenance...
Maintenance and Rehabilitation of Concrete Roads
For the repair of concrete roads to be effective and economic it is essential to have planned maintenance procedure. Details of such a procedure are to be published in the forthcoming publication "Manual for the Maintenance and Repair of Concrete Roads" ,which is to be adopted for roads administered by...
Development of the technological concept for roadbases made of hydraulic bound granular materials in the Federal Republic of Germany
A number of research projects relating to the cementbound sub-base (CBSB) are currently in progress in the Federal Republic of Germany. Their object is to develop an optimized technological approach with a view to further improvement and even greater economy in the use of this well proven form of construction....
Use of and construction method for concrete block paving in the Federal Republic of Germany
For hundreds, indeed thousands of years, the only form of road surfacing was with stone blocks. The invention of tbe internal combustion engine and the tremendous growth of motorization, in conjunction with the use of asphalt, thrust the block-paved road into the background and bad a major effect on the...
Critical assessment of various construction techniques
The long-term behaviour of various types of road pavement construction can be estimated or prognosticated from a methodical assessment of the condition of the roads and the associated data collection. Prognoses can be made not only with regard to technical cri teria, but also with regard to overall cost trends...
Side drainage and sub-soil drainage layer operation and performance
A very favourable result emerges from the assessment of the soundness of structural arrangements adopted and developed over the past ten years (3rd International Conference at Purdue, April (985). After briefly reviewing this positive achievement resulting from closely concerted action of road managers, practical engineers and researchers, the authors more...
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...
Noise protection walls (Design and construction)
Since 1972 between 250,000 and 300,000 m2 of acoustic screening (noise reduction) barriers have been built in France, i.e., 70 - 80 km of such structures of medium height (2 - 6 m), along the roads. They have been installed under a policy of both road and rail traffic noise...
Construction alternatives for drainage when reconstructing motorways
Arrangements for surface and for the harmless di.scharee of saepaee water are dealt with. A differentiated analvsis of the long-term behaviour of the solutions adcp ced is g~ven, depending on the substantially different soils occuring as road foundation and subgrade. In connection with surface drainage the drainage arrangements at the...
