Reduction of construction time and cost of road pavements

Road authorities who want to build, rehabilitate or repair pavements wish, for many reasons, to do this in the shortest possible time and at the lowest cost. However construction time and costs are often conflicting parameters. Hence the issue of reducing construction time and costs, without affecting the quality of the works, must be considered as a problem of optimization. A number of tools are available including: tendering procedures, the selection of technical solutions, organization methods [...]

Dealing with the effects of climate change on road pavements

Climate change can have a direct impact on the performance of our transportation infrastructure. The purpose of the report is to sensitize the road sector to the likely impacts of climate change on road pavements and to provide guidance on how to go about: -Assessing the vulnerability of road pavements to the direct impacts of climate change, and; -Identifying and prioritizing possible adaptation measures for road pavements that could be applied immediately or phased in over time, so as to [...]

Evaluating the performance of automated pavement cracking measurement equipment

Crack type, severity and extent are among the most important data of a pavement management system. This report prepared by Technical Committee 4.2 Road/Vehicle Interactions of the World Road Association presents: A series of objective rules to measure and classify cracks in order to improve the reproducibility of the cracks measurements; Three methods of evaluation of the reliability of automated crack measuring equipment : one test at « research » level, one test at « project » [...]

Evaluating the performance of automated pavement cracking measurement equipment

Crack type, severity and extent are among the most important data used to identify maintenance and repair actions. The use of automated crack measurement systems is increasing although performance tests of these devices are only conducted infrequently, and these are very often incomplete and non-uniform. The objective of this technical report is to help road administrations select automated systems in regard to their needs, therefore increasing the quality of the crack data used in pavement management [...]

Review of the growth and development of recycling in pavement construction

This report presents an overview of the use of recycling techniques in pavement construction in many countries. It highlights the barriers to recycling and describes systems and approaches that assist in overcoming these barriers. The incentives that are discussed are related to client awareness, appropriate technology, the benefits of recycling from an environmental and economic point of view and the implementation of regulatory and legislative measures. The report contains an appendix including [...]
