Relation between binder properties and damage characteristics of pavements (Performance orientated methods) (VSS1999/131)
Overview
Background & policy context:
Faulty or qualitatively insufficient binder, according to pavement experts, are the main reasons for a wide range of pavement damages. In particular thermal and fatigue cracking, missing interlayer bond strength, raveling and rutting have to be mentioned. The new research project has to find a relationship between these damages and the corresponding binder properties.
Objectives:
The objective of the project is to determinate the connection between binder properties and distress type; preparation of proposals for the transfer to the practice.
Methodology:
During the project following steps are done:
Finding appropriate road surfaces with binder damage proved to be far more difficult than expected. Despite a survey of the cantons of the planned number of sampling could not be conducted. This year, this should be taken again in attack and begin carrying out the checks.
