Possibility of Using Concrete Roads in Turkey

Highways Members Only

Axle loads are increasing all over the world including Turkey. Asphalt pavements are not able to carry this heavy traffic safely and economically. Using asphalt pavement for heavy traffic cause early deterioration of the pavement and higher cost of pavement maintenance. As an alternative, concrete pavements may be used instead...

The Pavers System a Knowledge Sharing Concept in the Design and Assessment of Road, Airfield and Industrial Pavement

Highways, Industrial Members Only

Rigid pavement thickness design is either still based on the classical Westergaard solutions or is based on a more comprehensive finite element rigid pavement model to resolve the shortcomings of the layered elastic Burmister model. The latter gives a principally better representation of the slab edges and joints. However, because...

The Application of the Selected Cements in Building Concrete Pavements of the Rural Roads in Poland

Highways Members Only

For the present Polish Catalogue of Typical Concrete Pavements is published. This document allows to apply cements CEM II and CEM III besides CEM I in road constructions. In order to verification of usefulness these cements, the experiment concrete pavement with CEM II and CEM III and for comparison CEM...

SFRCS for Concrete Roads in Heavily Trafficked Situations

Highways Members Only

The concrete slab is the main structural component of the road. It transmits loads to the sub-base. SFRCs (Steel fiber reinforced concretes) can be used in the road-base as a structural part of the road. Steel fibers allow greater joint spacing in road construction; they have a significant positive effect...

Development and Application to the Test Pavements in the Real Way of Eco-Friendly Hybrid Type Permeable Concrete Pavement

Highways Members Only

A new type of pavement structure was proposed and applied to the construction of two different trunk roads. The hybrid structure is composed of two basic layers of the porous concrete surface course which has sufficient functions of smoothness, skid resistance, permeability and low noise and of the less permeable...

Concrete Safety Barrier in the UK

Highways Members Only

This paper describes the usage of concrete safety barrier on high speed roads in the UK, drawing on experiences gained over the 10 years since their introduction, and the enhancements and improvements developed in this time. The paper is primarily concerned with in-situ slipformed concrete safety barrier and comments on...

Concrete Pavements on Bridges

Highways Members Only

Pavements on bridges are a very problematic element for each road administration. Classic European solution, concrete bridge deck with waterproofing membrane and pavement with asphalt wearing course, makes a lot of problems with maintenance, road closures etc. The paper presents results of research in the field of concrete pavements on...

Long-Term Behaviour of Concrete Pavements in Germany

Highways Members Only

Until about 1970 in general Jointed Reinforced Concrete Pavements (JRCP) with expansion joints were in use in Germany. In 1965, the highway administration came to be convinced for the first time by theoretical investigations to construct a Jointed Plain Concrete Pavement (JPCP) with short contraction joint spacing of 5 m...

A Low Cost Equipment For Accelerated Testing of Pavement Materials

Highways Members Only

Testing the behaviour of different pavement materials under repeated application of loads has been recognized as very essential to predict the performance of pavements. Most of the methodologies /equipments used to carry out such tests involve huge sums of money both in terms of initial investment and recurring expenditure. Also,...

Backcalculation Analysis of Concrete Pavements Using Fuzzy Logic Approach

Highways Members Only

It is known that concrete and flexible pavements are similar each other from the structural view point. Nowadays, especially, because of the innovations in airplane technology, airplane weights have been increased. Therefore airport maintenance has become more important. It is possible to obtain information about structural performance of a pavement...

Benefit of Reduced Fuel Consumption from Economic and Environmental Perspectives – a Novel Approach

Highways Members Only

Road traffic now represents one of the major sources of environmentally and hygienically harmful emissions. A reduction of the total quantity of traffic-related emissions would therefore yield great environmental benefits. A number of independent studies have demonstrated that the properties of the road, such as surface texture and rigidity, affect...

Cement Containing Granulated Blast Furnace Slag in Local Roads Building

Highways Members Only

The number of roads with concrete surface in Poland is small. During the last few years the cement industry has taken up extensive promoting activities that resulted in increased interest in construction of concrete roads – both motorways as well as local roads. It has turned out that durability of...
