Flexible road pavements deteriorate primarily due to traffic and adverse environmental conditions. Cracking is the most common deterioration mechanism; surveying thereof typically conducted manually using internationally defined classification standards. In South Africa, use of high-definition video images has been introduced, which allows for safer surveying. However, still a tedious manual pr...

This report provides a summary of the results of the various studies completed in the Partnered Pavement Research Program (PPRC) during the period 2000–2004. In addition, preliminary findings of investigations, initiated but not yet implemented during this period, are included. The results are based on the combined results of analytical developments, laboratory testing of pavement materials, an...

Considering the high price and number of natural resources used in transport infrastructure, extending pavement lifetime is a priority for engineers. One most common issues flexible maintenance are reflective cracks, which reduce driving comfort passenger safety. These cracks have two main origins, those initiated by shrinkage cement stabilized layer reflected from old to new overlay. During ro...

In this research study three dimensional (3D) finite element analysis are performed on a flexible pavement section for different material properties, temperature and loading conditions. The main objective of is to predict the rut depth under conditions temperature, loadings properties. Three model developed using ABAQUS depth. system assumed be an elastic multi-layers with each layer being isot...
