The state of Victoria in Australia has many major roads assets. These roads, stretching about 196,000 in km, have to be maintained and managed by VicRoads, the road authority of Victoria[1], and the local councils. Pavement Management Services (PMS) [2] company was employed by VicRoads in 2002/3 to do the analysis and detection of the pavement cracking in Victoria. PMS uses up to five industria...

According to the characteristics of airport pavement traffic, we discuss a method of building an airport pavement traffic model which is based on CPN theory and simulate a practical situation as well. The method overcomes the shortage of modelling with normal Petri Net theory, solves the difficult problems of airport pavement traffic such as complex traffic nets, frequent road changing, etc., r...

Road pavements have considerable environmental burdens associated with their initial construction, maintenance and usage, which has led the pavement stakeholder community make congregate efforts to better understand and mitigate these negative effects. Life cycle assessment (LCA) is a versatile methodology to quantify the effect of decisions regarding the selection of resources and processes. H...

Last years witnessed the growth of demand for road monitoring systems based on image or video analysis. These systems usually consist of a survey vehicle equipped with photo and video cameras, laser scanners and other instruments. Sensors mounted on the van collect different types of data while the vehicle goes along the road. Recorded video can be geographically referenced with the help of glo...

Good quality base and sub-base material for road pavement construction is becoming increasingly scarce. Dolerite is one of the more abundant natural road building materials in South Africa. Yet, it seems that the road design and construction fraternity shy away from using it in favour of more expensive commercially produced crushed material – and so artificially increase the scarcity of natural...

This work presents a hydraulic anti-lock braking system (ABS) for a motorcycle. The ABS has a hydraulic modulator and an intelligent controller. The hydraulic modulator is analyzed, and then equipped on a scooter for road tests. The intelligent controller controls the hydraulic modulator by estimated vehicle velocity to calculate the slip ratio of the wheels in real time. The performance of the...

The present paper deals with a view of the availability of high-speed sensor profilers, which has given dramatically increased possibilities to analyze imperfections in pavement surfaces such as roughness. Technical parameters of such profilers, for sensing and analyzing pavement surface profile are described. In addition, the main investigation concentrates on the evolutional process of paveme...

The main role of the present work is to conduct pavement performance evaluation of Cell Filled Concrete road constructed in Sidlaghatta taluk of Chickaballapura District in Karnataka. The study area selected is from Anur Hunasenahalli to T-07 (2.16 km) in Sidlaghatta Taluk. The above selected road is categorized under Village Roads (VR) and is constructed under the Technology Demonstration Proj...
