Sensitivity Analysis of Various Cost Elements in Flexible Pavement Design
This paper presents a method for predicting the optimum initial service life and optimum periods of resurfacing for flexible pavements. The method is based on consideration of total pavement costs including the cost of initial construction, routine maintenance and major maintenance and increased road user costs resulting from the maintenance operations. Standard economic analyses techniques wer...
متن کاملPreliminary Flexible Pavement Rehabilitation Design
The development of a knowledged-based expert system to assist ~he New Mex~co State Highway and Transportation Department m the evaluation and design of rehabilitation schemes for flexible pavements is described. The system uses information provided by users to establish preliminary rehabilitation schemes that would be reasonable and cost-effective. A cost-estimate module for ~anking th~ rehabil...
متن کاملFlexible Pavement Test Sections for Studying Pavement Design
It is a well-recognized fact that our pavement design procedures are inadequate in general and seriously lacking in many particulars. The fact that this statement can be applied on a county, state or national basis is little consolation to those in Indiana who must design and build pavements, for ever-changing traffic conditions, in such mileage and at such unit costs compared to the funds avai...
متن کاملArtificial Neural Network Application for Flexible Pavement Thickness Modeling
Flexible pavements are affected by moving vehicles, climate and other environmental factors. As a result of these factors, the pavement starts to deteriorate. In order to prevent further deterioration, a maintenance program should be carried out at right time and right places. For the determination of the structural carrying capacity of the pavement, non-destructive testing equipments are used....
متن کاملIs Flexible Pavement Design on the Right Road?
The principles underlying current mechanistic–empirical pavement design methods for fully flexible pavements have changed little in the past 30 years. They generally use linear elastic theory to determine the permissible strain at critical locations in the pavement structure to safeguard the road against excessive fatigue and structural deformation. These criteria are calibrated using performan...
