Abstract: Large amounts of money are spent annually on sealing or overlaying cracked road pavements, however, the reflection of cracks through these materials is a problem experienced worldwide. In countries with well-developed road infrastructures where the road networks are ageing (and available funds are often decreasing) it is becoming increasingly important to apply successful and cost-effective rehabilitative measures. Even though materials such as bitumen-rubbers, geofabrics and polymer-modified binders demonstrate some ability to retard reflection cracking, they still sometimes fail prematurely. In South Africa, the lack of performance-related design procedures, criteria and specifications for the selection of materials to solve specific problems, has led to a number of research projects.
