The fast development of car technology has caused a steady increase in the speed of vehicles and increasingly higher demands on braking and traction. International studies show that every increase in average speed causes increase in personal injury accidents. Yet the present transport infrastructure in general and cement concrete pavement...
How Does the Micro and Macrotexture of Cement Concrete Pavement Affect the Skid Resistance of Road
Combustion of Asphalt and Concrete in Case of Fire in Roads
The present study concerns the comparison of the behaviour at high temperature of an asphalt and that of concrete, the purpose being to define the parameters of choice of the material for the construction of roads, in particular in tunnels. To do this, laboratory tests of fire, thermal behaviour and...
Modieslab Innovative Prefabricated Modular Concrete Slab For Concrete Roads and Airfields
The Dutch Federal Highway Administration introduced the project Roads to the Future in the year 2000. Amongst other innovations, the MODULAR ROAD, was one of the sub-projects. In a contest several parties in the roudbuilding business were asked to develop an idea for a modular type of road that had...
Investigation of Maintenance Needs For In-Service Concrete Pavements
Given the large number of concrete pavements that have performed well over time and lived up to prior expectations, as well as the knowledge that is now available regarding the reasons for failure in certain concrete constructions, it should be possible to carry out an evaluation of these pavement types....
Rapid Replacement of Deteriorated Concrete Slabs Under Traffic
In the course of utilization the utility value and condition of concrete pavements decreases due to traffic and environmental burden. Their utility value is judged by edge/corner demolitions, settlements, horizontal movements and the overall condition. In case of damage individual slabs must be replaced. The aim of this study is...
Repair of Concrete Pavements Under Op-Eration
Don't we all loath them traffic jams. Irrespective of how we are affected by them, either directly as a user of traffic infrastructure or as a construction worker involved with its upkeep or indirectly as a conscious citizen aware of their economical impact, we all wish they could be...
Rehabilitation of Concrete Slabs by Sifcon-Overlays
A new means for rehabilitation of severely cracked concrete slabs is a thin overlay of SIFCON (Slurry Infiltrated Fibre Concrete). This high strength concrete with an extremely high content of conventional steel fibres (about 10 % of volume) was invented in the USA and further developed by the central laboratory...
Use of Crack and Seat in Concrete Pavement Rehabilitation a Case Study
This paper describes the processes carried out in the crack and seat of an existing concrete pavement on the M40 Motorway in England.
Repair of Concrete Pavements Using High Performance Concrete
When heavily trafficed concrete pavements are being renewed, the work generally has to be carried out under considerable time-pressure. A newly developed, high performance repair concrete is ideally suitable for such repair work on account of its high early and final strength as well as its durability. It is produced...
A Study on the Thin Precast Concrete Pavement for Rehabilitation of Asphalt Pavements
Precast concrete pavcmrnts have the merit to supply concrete slabs of good quality. In the concstructiori of precast concrete pavements, it is not necessary to use any special machines. And the special merit is that traffics can open immediatly because of unnecessary of curing. So this type of concrete pavement...
Use of Calcium Aluminate Cement in High Strength Concrete for Fast Repair of Old Concrete Slabs
The oxides present in the chemical compositioii of calcium aluminate cement, especially monocalciiim aluminates. is what gives the concrete manufactured with this type of cement its slow setting, quick hardening properties. The products generated during hydration of anhydrous phases in calcium aluminate cement. will depend on ambient conditions at the...
Pavement Design Procedures for New Construction and Rehabilitation with Overlay
The first part of the paper deals with the designing of rigid pavements by means of FEM. The NE10-SOILIN program uses the NE-10 finite elements composed of subelement 2D NE-10-M (tetragonal element), subelement 3D NE-I013RJCK and subsoil element. It models the Midlins slab placed on a generally multilayer structure. Under...
