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...

Newer technologies such as warm mix asphalt (WMA) and reclaimed pavement (RAP) have gained international approval been considered appropriate solutions that support the sustainability goals of highway sector. However, both present some shortcomings. The lower mixing compaction temperatures WMA reduce binder aging bond between aggregates coating binder, thus resulting in less rutting resistance ...

The majority of recent research in has been focused on the introduction, development, and evaluation performance-based specifications for design asphalt concrete mixtures. In Caribbean, most laboratories only use Volumetric Marshall Mix methodology. Road designers, engineers, consultants, contractors have all highlighted many shortcomings inadequacies volumetric mix selection process. consensus...

Recent technological developments have attracted the use of machine learning technologies and sensors in various pavement maintenance rehabilitation studies. To avoid excessive road damages, which cause high costs, reduced mobility, vehicle safety concerns, periodic roads is necessary. As part works, conditions should be monitored continuously. This monitoring possible using modern distress det...

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...

Roads are the main transportation system in any country and, therefore, must be maintained good physical condition to provide a safe and seamless flow transport people goods. However, road pavements subjected various defects because of construction errors, aging, environmental conditions, changing traffic load, poor maintenance. Regular inspections therefore recommended ensure serviceability mi...

The determination of pavement layer stiffness is an essential step in evaluating the performance of existing road pavements and in conducting pavement design and analysis using mechanistic approaches. Over the years, several methodologies involving static, dynamic, and adaptive processes have been developed and proposed for obtaining in-situ pavement layer moduli from Falling Weight Deflectomet...
