The depiction of the irregularity in nature is crucial for the realistic representation of the virtual 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 surfaces and clean texture images. In this paper, we suggest a method for representing re...

Road networks are a national critical infrastructure. The road assets need to be monitored and maintained efficiently as their conditions deteriorate over time. The condition of one of such assets, road pavement, plays a major role in the road network maintenance programmes. Pavement conditions depend upon many factors such as pavement types, traffic and environmental conditions. This paper pre...

As more and more utility installation and/or maintenance activities are located in highly congested urban roadways, frequent pavement utility cuts in such areas may cause more traffic disruption as well as deteriorate pavement life and quality. Utility owners normally need to obtain permits from public road authorities before commencing utility activities; however, public road authorities in Ta...

Accelerated Pavement Testing (APT) facilities are nowadays considered fundamental for the thorough understanding of the performance of pavements. The amount of information that can be derived from APT investigations can serve as the basis for a more performance-related pavement design but also for the development of new pavement types and innovative materials. In the design and use of such faci...

A pavement management system (PMS) is a valuable tool and one of the critical elements of the highway transportation infrastructure. Since a vast amount of pavement data is frequently and continuously being collected, updated, and exchanged due to rapidly deteriorating road conditions, increased traffic loads, and shrinking funds, resulting in the rapid accumulation of a large pavement database...

This paper describes the Accelerated Testing with the LINTRACK-facility of the innovative ‘Rollpave’ test pavement that was developed within the theme ‘Modular Pavement Structures’ of the project ‘Roads for the Future’ of the Dutch Ministry of Transport, Public Works and Water Management. The concept of ‘Rollpave’ is a thin pre-manufactured asphalt wearing course that is rolled on a reel. On si...

Semi-flexible pavement surfacing is a composite pavement that utilizes the porous pavement structure of the flexible bituminous pavement, which is subsequently grouted with appropriate cementitious materials. This study aims to investigate the compressive strength, flexural strength, and workability performance of cementitious grout. The grout mixtures are designed to achieve high strength and ...

As every driver knows, when pavement deteriorates, it becomes rougher. What drivers may not realize is that the roughness they feel in the seat of their vehicles not only makes the drive less comfortable, but it also leads to a cycle of increasing deterioration rates with increasing roughness severity. To prevent this cycle of everincreasing roughness and deter iorat ion, engineers try to perfo...

Municipal engineers are faced with the difficult task of managing the urban roadway network. Maintaining this significantly large and expensive infrastructure requires effective planning and design. However, the majority of currently available design tools were developed originally for analyzing highway pavements. Little attention has been given in the past to urban road related issues. The env...

In this paper, we test whether an autonomous robot can be used to measure the International Roughness Index (IRI), a description of pavement ride quality in terms of its longitudinal profile. A ready-made robot, the Pioneer P3-AT, was equipped with odometers, a laptop computer, CCD laser, and a SICK laser ranger finder to autonomously perform the collection of longitudinal profiles. ProVAL (Pro...
