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...

Concrete block pavement (CBP) is a durable pavement for carrying light as well as heavy loads, and it is being used widely for construction of city streets, parking places, gas stations, container stacking yards, residential areas and low volume roads. This paper presents the findings of a laboratory investigation on structural behaviour of CBP. Plate load and Accelerated Pavement tests were ca...

The depiction of the irregularity in nature is crucial for the realistic representation of the real world. For example, real pavement blocks are not always paved evenly, but partially sink over time. Many games or virtual reality systems however represent the pavement too neatly with perfectly flattened surface and clean texture images. In this paper, we suggest a method for representing realis...

Designing a new bridge structure or designing the rehabilitation of an existing is time-consuming process. It important for owners to proactively assess their structures make sure that by time replacement required, design phase elements such project, including necessary permits, are ready. Assessing future condition also helps owner evaluate variety choices options based on risk imposed each al...

Life-Cycle Assessment (LCA) analyzes the total energy and resource requirements and environmental impact of human-designed systems. Both policymakers and industry have shown a great deal of interest in applying LCA as a decision-making criterion during planning and design for new pavement construction, and maintenance and rehabilitation activities. This interest results from two different persp...

It is well known that road safety issues are closely dependent on both pavement structural damages and surface unevenness, whose occurrence is often related to ineffective pavement asset management. The evaluation of road pavement operability is traditionally carried out through distress identification manuals on the basis of standardized comprehensive indexes, as a result of visual inspections...

This paper describes the use of artificial neural networks (ANN) for predicting non-linear layer moduli of flexible airfield pavements subjected to new generation aircraft (NGA) loading, based on the deflection profiles obtained from Heavy Weight Deflectometer (HWD) test data. The HWD test is one of the most widely used tests for routinely assessing the structural integrity of airport pavements...

Reinforcement using an interlayer system has been demonstrated for more than four decades as a multi-purpose solution to improve performance, to extend service life and thus to reduce maintenance costs of road pavements. Among a large number of existing interlayer systems, glass fiber grids have shown effective use in pavement reinforcement with a hot mix asphalt overlay. Recently they have rec...
