The curing compounds hitherto employed have not always been found satisfactory when applied to road concrete with superplasticizer, to concrete on small jobs, to concrete placed by slipforming and to cement-boundsurfacings. For this reason three new types of curing compound have been introduced, namely, compounds which - give good protection...
Construction of airfield pavements with concrete
Concrete pavements have for years been successfully used in airfield construction. The relatively high weight of the landing gear of large aircraft requires pavement thicknesses which are considerably higher than those of concrete roads. The construction of airfield concréte pavements requires appropriate placing techniques. On account of the high loads...
Critical views on the procedure for and assessment of concreteroad conditions (Results of an investigation carried out on behalf of the Ministry of Transport
The resu l.cs of a research project are reported in ,which a method for the visual surveying of the condition of concreee roads was developed. In collaboration with three Federal German States, the road maintenance procedure hitherto applied was examined. The furcher investigation comprised the development of data recording sheets...
Use of slags in concrete pavements and sub-bases
Industrial by-products have long been used in French road construction. Experience gained over the last twenty years with che extensive use of by-product gravel-sand stabilized with hydraulic binders as a sub-base material, as well as the results of highway engineering practice in neighbouring countries like Germany and Belgi~prompted the LPC...
