Analyses the current road pavement maintenance technical specification, put forward a new evaluation method for maintenance and overlay of old asphalt pavement. Considering the uncertainty and complexity in the process of performance evaluation, and based on the entropy and the Kohonen network theory, the performance evaluation system is established in Kohonen network of fuzzy entropy method, c...

This study demonstrates the use of Class F fly ash in combination with lime or lime kiln dust in the full depth reclamation (FDR) of asphalt pavements. FDR, in the context of this paper, is a process of pulverizing a predetermined amount of flexible pavement that is structurally deficient, blending it with chemical additives and water, and compacting it in place to construct a new stabilized ba...

Municipal engineers are faced with the difficult task of managing the urban roadway network. Maintaining this significantly large and expensive infrastructure requires effective planning and design. However, the majority of currently available design tools were developed originally for analyzing highway pavements. Little attention has been given in the past to urban road related issues. The env...

This paper discusses the continuation of the research work started in 2004. The previous results have been published both in ASPRS and ISPRS conferences. Now we intend to emphasize the latest developments and extended application areas of the system. Due to the increasing demand of the transportation authorities for rapid, accurate data acquisition about the road pavement, a mobile mapping syst...

This study aims to quantify and compare the life-cycle environmental, economic and social impacts of two pavement materials: namely 10mm Asphalt Rubber Stone Matrix Asphalt (ARSMA10) and 10mm Polymer Modified Stone Matrix Asphalt (PMSMA10). To achieve this objective, a comparative sustainability framework was developed by: 1) combining the Life Cycle Assessment (LCA) with pavement maintenance p...
