Issues and Perspectives in the Application of Different Pavement Design Methods to Life Cycle Cost Analysis

2016

Life cycle costs analysis (LCCA) is an economic evaluation tool that can provide valuable guidance to transportation officials in management decision process. The application of LCCA to pavement management is vital because it permits the selection of the best alternative, based on the analysis of agency costs and user costs, taking into account (after selecting pavement type) different maintenance and rehabilitation (M&R) strategies within the same pavement type. Additionally, environmental costs can be considered. Issues arise when comparing the expected life of the pavement derived according to different pavement design tools, such as the Mechanistic-Empirical pavement Design Guide (M…

SURFACE AND MECHANISTIC PROPERTIES OF RECYCLED BITUMINOUS MIXTURES

2019

EXECUTIVE SUMMARY Problem Often, when the characteristics of a bituminous mixture are analised, there are major differences between in-lab and in-situ results. This is due to the fact that the procedures and techniques implemented during the design phase (in lab) may be different from those used on site. Then, is very important to be able to predict the main properties of a mixture particularly when innovative materials are used. For example, when crumb rubber is used, phisical and volumetric properties of mixes may change over time, in particular due to the swelling phenomenon that it alters different properties of the mixture (e.g., viscosity). This study aims to investigate the main aspe…

AN INTEGRATED MODEL TO EVALUATE TECHNICAL ENVIRONMENTAL AND ECONOMIC SUSTAINABILITY OF ROAD PAVEMENT

The unconditional exploitation of environmental resources, the emission of xenobiotic substances in nature and resulting pollution from the development of human activities have led, over time, to serious repercussions on the environment. Therefore these effects weigh on economic and social development. The need to deal with environmental issues and their relationship with economic development has led to the definition of sustainable development concept . The concept of sustainability combines three fundamental aspects which can not be separated, namely environmental, economic and social. The increasing sensitivity towards these socio-economic issues has driven research towards new fronts, u…

Pavement Management System model using a LCCA- microsimulation integrated approach

2014

The maintenance and the rehabilitation of the urban road pavements are not often based on systematic program and scheduling but rather on emergency or on other not identified reasons. Moreover the Life Cycle Cost Analysis (LCCA), the only peculiar procedure for the management pavement, finds its own application for highway and motorway, even if it is possible to search the best investment for the urban interstate and arterials. By the light of the quantity of the involved resources, it seems necessary to define an operative methodology for programming the maintenance and rehabilitation activities for the urban pavement. The paper is oriented towards the development of a multidisciplinary ap…

A multidisciplinary approach using LCCA and micro-simulation 10 model for the management of the urban pavements
