Conf. Paper (EUPAVE)

The upgrading of the A-495 between Gibraleón and San Bartolomé, in the province of Huelva (SouthWest of Spain), consists in an widenig of the cross section (which some years ago has been enlarged from 6 m in the original work to 8 m after a first rehabilitation) to 10 m...

We attempt to present the management of concrete pavements made by Aumar on motorways which is the concessionaire: data collection and its management, application of their model of pavement, performance of this one, repairs and rehabilitation.

This paper reports about the results of test sections on a concrete cycle track, where natural aggregates were replaced by selected crushed concrete. The test sections were built in 2006 and monitored directly after the winter periods. In the three tested concrete mixes respectively 50% and 100% of the course...

More and more importance is attached to the quality of the road surface, especially by the road users who want to drive on safe and comfortable roads. Concrete pavements often suffer from bad image due to the fact they are very old and have been designed according to other criteria...

The need for optimizing preservation and rehabilitation strategies used to maintain highway concrete and asphalt pavements has never been greater, given the current difficult economical outlook faced by highway agencies. Conventional bonded and unbonded concrete overlays have a long history of successful use to preserve and rehabilitate concrete and asphalt...

In Switzerland concrete pavements for roundabouts are considered a suitable and cost effective and above all a durable solution. The service life is estimated to be 40 to 50 years, what can only be achieved by concrete pavements.

The Sinard tunnel (length 980 metres), located South of Grenoble, is one of the few in France to have a concrete pavement. Once the tunnel was opened to traffic, in 2007, a campaign of photometric measurements was initiated to follow the evolution of photometric characteristics of the concrete pavement with...

A new section of main road Route Nationale 7 (RN7) has been under construction since 2007 between La Pacaudiere and Changy (Loire, France). The capping layer had to be treated with 1% lime and 5.5% cement. At the beginning of the working, the building company proposed another solution to build...

A 43 km long continuously reinforced concrete pavement was opened to traffic 34 years ago connecting three important cities in an industrial region in the North of Spain. Each carriageway has two lanes 3.75 m wide, an outer shoulder 3.00 m wide and an inner shoulder 1.50 m wide. A...

In 2004 the ACPA, PCA, and IGGA cooperated in a research effort at Purdue University’s Herrick Laboratories. The laboratory’s Tire Pavement Test Apparatus (TPTA) is capable of testing any texture design and is not constrained by construction capabilities or costs associated with field test section construction and evaluation. The research...

The noise emission performance of concrete roads has been a subject of thorough investigations in Austria in recent years. This focus is due to the predominance of concrete road surfaces in the Austrian high-level road network and to the long and successful tradition of using exposed aggregate cement concrete (EACC)...

The section of the E403 (A17) motorway between Bruges and Kortrijk was built in continuously reinforced concrete in the early nineteen eighties. The construction work was carried out in four phases with substantial differences between the phases with respect to the width of the pavement, the sub-base and the position...
