This paper describes work on the skid resistance properties of some fine aggregates available in Indiana, as an attempt to improve the driving safety characteristics of concrete pavements. In this work the British Polishing Machine and the Portable Skid-Resistance Tester were used for laboratory evaluation of some mortar mixes. Aggregates...

On asphaltic roads the so called «wash-boardeffect » in front of traffic lights is a well known phenomenon. Regular reconstruction of these areas places a significant and recurrent burden on road managing authorities. Because of the large volumen of traffic at these intersections repair works also lead to a huge...

This paper describes the studies, reports and experimental sections related to this new type of pavement, not conventional, composed of a thin concrete layer, but with a steel reinforcement, in sufficient quantity to resist the traffic loads. The description goes back to the first studies and tests carried out inthe...

The first known applications of RCC pavements in low-volume roads in Spain took place around 1969-1970. They included pavements located on housing developments, urban streets and rural roads. These applications have been increasing until now, when the technique is used in different parts of Spain and in other countries (Norway,...

This paper describes a method developed by the Belgian Road Research Centre for the design of cement concrete pavements and overlays. The object of this method is to avoid fatigue cracking of the surfacing (or overlay) and excessive permanent deformation of the subgrade soil. It results from the application of...

Questions regarding the environment are being particularly felt in certain countries, and noise con-trol requirements have led to the development ofthin free draining materials able to limit tirepavement contact noise.We shallbe dealingherenotwith a thin free draining pavement structure, butwith a porous concrete pavement of 40 cm thick-ness. Theoretical studies have...

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....

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...
