Pavement surface deflection measurements are usually conducted with different nondestructive testing methods. One of the most commonly used method is Falling Weight Deflectometer test (FWD), where an impulsive load is applied on pavement surface and the deflections are measured at a number of points radially distributed from the centre of falling weight. All the testing parameters are adjusted to correspond to the effect of loading due to standard axle on the investigated road. Laboratory for Transportation Engineering from Faculty of Civil Engineering Universi-ty of Rijeka in cooperation with Croatian Civil Engineering Institute (IGH) measured pavement deflections on the second longest and one of the most loaded Croatian highways A3 Bregana – Zagreb – Lipovac (E 70). This highwayis characteristic for a greater amount of heavy vehicle traffic whichis approximately 20% of total AADT and some highway sections were built 30 years ago, which were the reasons for the investigation of road’s structural capacity. In this paper part of the data collected with FWD test on one road section for both highway lanes will be presented. The aim is to interpret collected data for driving and passing lane for one highway section in Croatia.

Sight distance (horizontal, vertical) is one of the key factors in ensuring traffic safety at the level intersections and access points. Despite the relatively clearly defined demands in the legislation (eg. Act about public roads), where are defined responsibilities - both road owners and land owners in ensuring sight distances - in the everyday practice in this field situation is very different. Often - especially within/inside urban areas - inadequate sight distances "solve" with just a road mirrors, which often is not enough (or good solution). The purpose of this paper is to make a comparison of different standards/guidelines/ policies that define the scope of the sight distances on the level crossings/access points, carry out an analysis of sight distances and perform the analysis of sight distances according to real motor vehicle speeds. The aim of this paper is to examine the adequacy of existing calculations stand-ards in the level crossings and access points and define differences between calculations - ac- cording different standards/regulations.
