CONCRETE BLOCK PAVING IN THE NETHERLANDS DESIGN AND CONSTRUCTION

Abstract

Concrete block paving has become a dominant method for constructing flexible pavements in the Netherlands, especially in built-up areas with frequent repaving needs due to underground infrastructure maintenance. Traditionally, these pavements were based on a sand sub-base. However, recent advancements in pavement design have led to the adoption of a combined granular material and sand sub-base, catering to areas with heavy traffic and aiming for enhanced durability. This article explores the evolution of concrete block paving in the Netherlands, highlighting the transition from hand-paving methods to mechanical installation to improve labor conditions and reduce costs. It delves into the development of a new design method that calculates the expected lifespan of a pavement based on permissible rut depth, incorporating the effects of traffic loading and progressive stiffening of the pavement layers. A significant part of the article discusses the introduction and benefits of mechanical paving machines, which have revolutionized the paving process, making it faster and more cost-effective. These machines have also facilitated better working conditions for paviors, a necessity given the physically demanding nature of their work. Additionally, the article covers the establishment of a pavement management system designed to optimize maintenance schedules based on visual inspections and lifespan calculations. This system is crucial for efficient resource allocation and prolonging the service life of pavements. The findings and methodologies presented here are essential for future research and application in the field of pavement engineering, particularly in regions facing similar challenges as the Netherlands in terms of traffic conditions and maintenance needs.
