The composite pavement concept can be described as an association of bituminous layers or modular elements with cement concrete. The desired objective is the association of two or more layers of a different nature in such a way that the specific advantages of both types can be profited from thus...

In extensive examinations several measuring methods and parameters were tested and compared, in order to evaluate the effectiveness of different curing compounds and methods. Starting with basic tests concerning the time-dependent water-loss of concrete and the optimal application time of curing compounds, a simple test using a litmus-paper was developed....

A new concept of concrete pavement have been imagined and tested in France since 1998. It consists in a base layer of continuously reinforced concrete, bonded with a foundation layer of asphalt concrete. The stiffness of the asphalt material and its bonding with the concrete layer contribute to rigidify the...

Sponsored by the U.S. Department of Transportation, Federal Highway Administration, HIPERPAV (HIgh PERformance concrete PAVing) is a software tool capable of predicting the early-age behavior of concrete pavements. HIPERPAV successfully integrates materials, pavement design, climate, and construction operations into an easy to use Windows-based software package. Using a systems approach,...

The brightness of concrete pavements is, next to a multitude further, an essential advantage of this method of building vis-à-vis bituminous pavements, because brighter street surfaces affect positively the safety of the road users. Bright concrete surfaces provide above all an increase of safety in rain and in darkness (especially...

Skid resistance of a pavement surface is important for safety. Therefore the surface of a concrete pavement must have a roughness suitable for a high skid resistance but also for a low noise emission. These surface properties must be as durable as possible. In Germany there are various possible ways...

During last years more than hundred kilometres of concrete motorways at the southwest part of Poland were modernised and newly constructed. In the frame of modernisation the old existing concrete pavements, constructed in 30's of last century, were broken-up and the crushed concrete was re-used in new concrete pavement. Newly...

Temperature changes within concrete pavements are transient. Therefore the temperature characteristics along pavement thickness are not linear and have to be split into constant, linear and equilibrium parts for further investigations. The linear temperature gradients are causing additional loading on concrete slabs, which if not considered will influence the long-term...

Continuously reinforced concrete pavement (CRCP) has been constructed on major highways in several countries since the 1940’s. A large majority of these pavements have carried very heavy truck traffic but required low maintenance. Some have experienced problems due to inadequate design, support, and construction. This paper focuses on factors that...

This article gives an overview of the work that has been done so far to transform the N49 Antwerp- Knokke into highway E34. The work involved fits in with the major overhaul of the N49 between Antwerp and Knokke as far as the E34 motorway. According to the Flanders Regional...

The long service life of cement concrete roads, as well as the new objectives of contracting authorities taking into account significant extensions in hypotheses on the design service life of roads, streets and runways, oblige the technical civil engineering community to plan much more than in the past for the...

Shonan Ohashi Bridge that is on Route 134 is a steel box girder bridge of 530m in length. Six years ago, fatigue cracks were found at the welding tips of bottom deck plates. After the full inspection of the asphalt pavement and steel deck bridge, it was found that the...
