There have been significant developments in concrete road pavement techniques in the past decade. To the traditional advantages of concrete pavements such as durability under heavy traffic and low maintenance cost have been added various other reasons for favouring them, such operational availability, aesthetics, architectural integration and contribution to a...
Very Thin Bonded Cement Concrete (VTBCC) a New Quality Surfacing
Mechanical Properties and Structure of Porous Concrete
A test road with 40 n-mi porous concrete top layer on a 180 mm thick continuously reinforced concrete pavement has been constructed in May 1996 in Belgium following the wet-in-wet method. A preliminary test program was conducted at the Catholic University of Leuven to reveal the influence of different polymer...
Cement Concrete Public Highways Recent Developments in Technical Literature and Applications
In a still recent past, research and innovation in the field of concrete pavements progressed mainly within the field of high volume pavements for roads and airports. This sustained and productive effort remains, giving rise to an expertise well documented in technical publications. Several countries converge in adopting constructive measures,...
Fatigue Properties of Plain Concrete
Based on a literature search, several types of fatigue relationships were collected, compared and analysed for plain concrete (specimens, pavements) subjected to repeated loading. A uniform fatigue relation - based on the FS- R concept - has been proposed for the flexural tensile strength. The 50%-probability curves have been analytically...
Fibrous Ferrocement – An Ideal Material for Bridge Overlays
The overlays of highway bridges are usually subjected to stresses like impact stresses, longitudinal stresses, due to the application of brakes and wear and tear stresses. The moving loads on bridges have a jumping action due to uneven surface on which they move. This jumping causes shocks and vibrations of...
Air-Entraining Agents in Road Concrete Code of Good Practice and Field Experiments
Air-entraining agents are increasingly recommended as a mean to counteract the ever more severe deterioration of road cement concretes in winter. However, their use is still raising problems as far as the specifications and the practical implementation of the technology are concerned. The results of research conducted by BRRC and...
Roller Compacted Concrete Pavement Using Recycled Concrete Aggregate
Usage of recycled concrete aggregates produced from crushed demolished concrete has been limited due to its higher cost and the difficulty caused from its major ingredients, cement mortar, and by-product powder. However, the exhaustion of aggregate resources and increase demand of preserving the natural environment require developing an effective application...
Verification of the Acting of the Recycled Building Material for the Production of Rigid Pavements in Concrete of Portland Cement
The objective of the present work is the study of the technical viability of the use of refused material of building construction like aggregates for concrete roads. The first stage consisted of the physical characterization of the aggregates obtained through the grinding, followed by a study of the granulometric composition...
Life Cycle Cost of Urban Pavements
This paper attempts an actual analysis of the cycle cost of urban pavements through the discussion of a case study: the City of Buenos Aires, Argentina. Three frequent paving solutions for the local street system are compared: plain concrete and two different asphalt alternatives. Construction, maintenance, reconstruction as well as...
The Dutch Visual Inspection Method and Standards for Levels of Maintenance of Concrete Roads
In view of the evaluation of the Pavement Management System used in the Netherlands, this system will be made suitable for concrete pavements. Thcrefore two main elements of thp cyctem, the visual inspection method and standards for levels of maintenance for concrete pavements has been developed. The visual inspection method...
Fundamental Study on Bonded Ultrathin Whitetopping
Ultra thin white topping is a rehabilitation technique in which thin concrete overlay is placed on asphalt pavement in distress, and this work technique has been under research in Europe, USA and other countries. In this study, a small model experiment was conducted to see its applicability to the roads...
Utra-Thin Whitetopping Applications in Mexico
Since 1993, tliiee experimcntal test sections have been built in Mexico to study the performance of Ultra-thin Whitetopping (UTW) under different traffic conditions. In this paper, the construction, instrumentation and load testing of an UTW test section built on a major highway is described. Based on the experimental results, UTW...
