Pavement deterioration rate is very difficult to predict because of the complexities in determining the pavement condition rating or difficulty in collecting detailed data, particularly in absence of sophisticated equipment or trained staff etc. A wide variety of Pavement Maintenance Systems (PMS) are used, but unfortunately either these systems do not use a formalized procedure to determine th...

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...

Scrap tire rubber and nylon fiber are waste materials that could potentially be recycled used to improve the mechanical properties of asphalt pavement. The objective this research was investigate scrap (R-F) modified warm mix mixture (WMA). high-temperature performance estimated by Hamburg wheel-tracking testing (HWTT) device. low-temperature cracking evaluated disk-shaped compact tension (DCT)...

Various forms of asphalt pavement distress, such as rutting, shoving, and bleeding, can be attributed, in many cases, to low air voids in the mixtures during production and placement. The occurrence of low air void contents during plant production may originate as a result of an accidental increase in binder content or mix fines (or both). When low air voids are encountered during production, t...

Reinforced cement concrete is getting extensively used for construction of different type of structures for the last one century. During this period, we have constructed many structures like buildings, bridges, industrial structures, pavement, water tanks etc. using this construction material. These structures have been created with huge investment of resources. It is essential to maintain thos...

The primary objective of this study was to assess the pavement structural deterioration based on Non-Destructive Test (NDT) data using an Artificial Neural Networks (ANN) based approach. ANN-based prediction models were developed for rapid determination of flexible airfield pavement layer stiffnesses from actual NDT deflection data collected in the field in real time. For training the ANN model...

Technological advances, financial possibilities and changes of demands have increasingly affected the pavement maintenance environment for outsourcing in recent years. This induces complexity in the contracting methods of pavement maintenance activities. Despite the fact that current contracting practices on pavement maintenance activities are not sufficient to deal with changes providing the i...

Suitable evaluation of distress is beneficial to understanding the in situ performance deck pavement. This study attempts evaluate long-term American ChemCo epoxy asphalt concrete on Xihoumen Bridge (XHMB) after 12 years service. The traditional indexes were adopted reveal XHMB. Then, based typical distresses, a new pavement index (PPI) was proposed characterize authentic condition. Finally, an...

The present era, in particular, the last 3 to 4 decades can be easily named “Plastic Age” and dealing with plastic waste has always been a challenging affair for Urban local bodies. Plastic roads are bituminous or pavement that have blended mix their wearing courses. being sustainable technology becoming very popular nowadays as substitute conventional India other parts of World. Evaluation is ...
