Review on the Pavement-repairing Measures as a Condition for the Choice of Road-Maintenance Strategy

The road-maintenance strategies vary from one country to another, and even between the road management authorities within a one single country. It is not surprising, as there is not best maintenance method, nor a universal set of strategies that can be applied equally everywhere. Generally, there are strategies acceptable in certain conditions, but the factors influencing the selection process are diverse and very complex. This paper will present a review of the various measures that can be applied on the roads, which is certainly the basic condition of selection of an appropriate maintenance strategy

Validation of the hdm models forcrack initiation and development, rutting and roughness of the pavement

Worldwide practice recommends validation of the HDM models with some other software that can be used for comparison of the forecasting results. The program package MATLAB is used in this case, as it enables for modelling of all the HDM models. A statistic validation of the results of the forecasts concerning the condition of the pavements in HDM with the on-field measuring results was also performed. This paper shall present the results of the validation of the coefficients of calibration of the deterioration models in HDM 4 on the Macedonian highways

Methodology for analysing capacity and level of service for signalized intersections (HCM 2000)

The augmentation of motorization level leads us to the need for mobility and demands better infrastructure, in urban and suburban areas. The complexity of this problem is esspecialy notable in urbаn areas where the need for mobility must be considered, as well as the integration of infrastructure network in the urban plan of the city. Besides the space delimitations, functional characteristics and space demands connected with different transportation in cities. This methodology analyses the needs of the urban traffic network in highly populated areas, where space limitation and movements in peak hours must be considered. That is why the analysis of capacity and level of service is key part of the urban traffic planning. Highway Capacity Manual gives the opportunity to analyse the capacity and level of service of the roads in urban or rural areas, by defining the delay of the analysed facilities. To obtain these information, we must have data for geometric, traffic and signalization parameters, when the intersection is signalized
