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....

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....

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...

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...

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...

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...

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...

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...

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...

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...

The record of the first concrete road construction in India dates back to 1914. However, till the end of eighties, cement was a scarce commodity in India; therefore, concrete road construction was relegated to the background. After liberalization of cement market, concrete roads staged a comeback and in the nineties...

The skid resistance of any surface is an important characteristic for the driving safety point of view. The rain affects the traffic security, because there are splash and sprays effects caused by the truck wheel. This fact contributes to the dynamic hydroplaning effect. In recent years many agencies research’s has...
