Increasingly plastics become the material of choice by product designers because they provide useful properties and for this reason the worldwide production of plastics is growing year after year. At the European level the reference concerning the recycling and reuse of waste plastics obliges Member States to recover and recycle...
Investigation on the Possibility of using Concrete Containing Plastic Waste as Aggregates for Pavement Construction
The Surface Picture of Non-Reinforced Concrete Pavements During Its Usable Lifetime as a Decision Basis for Maintenance
The performance of road surface is the first and main indicator of information of the condition of the road. For some singular damages in-depth analysis is not necessary; for these an instruction for an appropriate maintenance measure is possible. However, by area-wide recurrent or systematic damages causes are important in...
Concrete Pavement of the Access Ramp Bridge of the Peza Truck Holding Area of the Bale-Weil Customs Facility, Switzerland
This document describes the design and construction of the concrete pavement for the relatively steep access ramp bridge of the PEZA truck holding area of the Bale-Weil customs facility. The pavement design takes into account the expected change in usage after 2008 as a motorway offramp and harbour access route....
The Way Ahead is Fibre-Reinforced
For several decades steel wire manufacturers produce steel fibres which can be mixed with concrete to improve its characteristics. FIBRICON® is a multi-fibre concrete a combination of concrete and three types of fibres. The fibre mix consists of drawn or rolled steel fibres with profiled end hooks or anchors....
Concrete Roads Constructed on the Lincent Land Reparcelling Site
The concrete road technique has been used for many years for the creation or improvement of roads in land reparcelling project areas. The designs used for these roads have had to develop for a variety of reasons: 1. Vehicles are becoming increasingly heavy. Semi-trailer rigs carry crops directly from the...
The European Standards on Materials for Concrete Pavements
CEN Technical Committee TC 227 is responsible for the European Standards dealing with road materials. As a part of its working programme, 33 standards have been prepared concerning materials for concrete pavements. Six of them deal with specifications for materials, functional properties of concrete pavements, dowels and joint sealants (hot...
The Superbus Concept and Its Supertrack Infrastructure
Superbus is an innovative new concept in personal public transport, developed by the Delft University of Technology. The Superbus consists of a highly advanced vehicle that can reach speeds up to 250 km/h a special Supertrack Infrastructure and advanced IT applications for services on request, road handling and comfort and...
First Use of Whitetopping in Switzerland
This document describes the design and construction of the concrete whitetopping repair of a severely distressed pavement of a road section at a regional road intersection. In the past, repair of this road section with asphalt overlays repeatedly failed to withstand the severe shear loading to which the pavement is...
Developments on the Modieslab Innovative Concrete Pavement Concept
Modieslab, a recently developed innovative and settlement-free precast concrete pavement structure, with a twin-layer porous concrete wearing course, was tested for its functional and structural properties on two full scale test pavements. Some functional properties, e.g. noise reduction, were very satisfying, however the resistance to raveling and especially the skid...
Heavily Reinforced Ultra Thin White Topping to Re-Strengthen Infrastructural Structures
Thin white toppings (TWT), as originally developed in the USA in 1918, are in majority placed as an overlay on deteriorated asphalt pavements. Usual thicknesses were 150 225 mm but since the last 30 years also ultra thin white toppings (UTWT) with thicknesses of 75 150 mm are...
Wheel Tracks, the Compromise Between Agricultural and Environmental Interests
In certain areas there is a need to surfacing sand roads due to agricultural developments: mechanisation and efficient management of farming activities are essential. Farmers must have direct access to the fields at all times without too many obstacles. However, attention must also be paid to various other aspects: environmental...
A Feasibility Study of Incorporating Bottom Ash in Roller Compacted Concrete Pavements
Roller compacted concrete as a pavement material has been gaining acceptance over the past years. RCC can be of particular interest in base course applications combing attractive cost with easiness of construction. RCC is a friendly pavement material to incorporate by-products of industries such as bottom coal ash. This paper...
