Block or slab pavements with concrete or natural stones are mainly used for communal areas, where a variety in creation is welcome, but also the lifespan of the pavement is very important. At pedestrian precincts, which are also trafficked by trucks, often high vertical and horizontal loads occur. If the...

In this paper, the economic analysis has been done on both flexible and rigid pavements. These cost analyses play a great role on the decision-making stages in selection of pavement types. In this analysis initial cost of rigid and flexible pavements have been determined for both flexible pavements and rigid...

In view of increasing operation and maintenance requirements on existing concrete roads, it is im-portant to gain knowledge about their present bearing capacity. For this task, the Falling Weight Deflectometer (FWD) has proved to be of practical value for years in Germany and other countries worldwide. The FWD is a...

Argentina has a rich history in concrete pavement construction. However, in the late 70s this type of pavement begins to lose protagonism in national road activity. In order to reinstate this solution for paving and rehabilitation projects, the Instituto del Cemento Portland Argentino, in the mid-90s, carried out a series...

The Brazilian Army looked the Associação Brasileira de Cimento Portland (ABCP) for a strategic partnership, aiming to transfer technology and train the troops for such works. The result of this partnership was a full concrete pavement construction and control technology course, lasting two weeks, covering all stages, also including practical...

As an example of Spanish experience in the design of long-life pavements, this paper is going to examine the above-mentioned construction project for a stretch of motorway with a pavement of exposed aggregateexposed aggregate concrete. The cross-section of the pavement comprises: - 23 cm of HF 4.5 (concrete with a...

Prescriptions for concrete pavements issued by the Spanish Road Administration are included in two types of documents: the Standard for Structural Sections of Pavements (6.1 – IC) and the Specifications for Road and Bridge Works (PG 3). These documents were updated considering the latest advances in materials, construction processes and...

The Sevilla – Cádiz motorway was the first one in Spain where a concrete pavement was constructed with a slip-form paver. It was opened to traffic in 1971. Shortly, longitudinal cracks appeared, deemed to the presence of plastic soils in the subgrade. Sometimes these craks were several centimetres wide. It...

Long-life concrete pavements require less frequent repair, rehabilitation, and reconstruction, and therefore contribute to improving highway safety and mitigating congestion. Experience with these pavements, including examples of concrete pavements that have remained in service for more than 35 years. CRCP set out to offer the market a new alternative in...

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...

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.
