Reliable and durable asphalt surfacing systems still remain to be desired for the long-spanned orthotropic steel bridges as the nationally and internationally reports on distresses in deck pavement. Based on ten-year research works, this paper has presented a brief review and discussion of the Chinese practices and experiences of deck pavement on long-spanned steel bridges, including issues of ...

Every year a great amount of money is expended for the rehabilitation and reconstruction of roads and pavements in most countries. Besides, making an ideal decision on this based on the types of failures determined, takes too long. The rough-set theory is an e ective tool for the analysis of information systems in a Pavement Management System (PMS) database gained by both objective and subjecti...

Previous research suggests that people tend to see faces in car fronts and that they attribute personality characteristics to car faces. In the present study we investigated whether car design influences pedestrian road-crossing behaviour. An immersive virtual reality environment with a zebra crossing scenario was used to determine a) whether the minimum accepted distance for crossing the stree...

We evaluated the strength and durability characteristics of latex-polymer-modified, pre-packed pavement repair concrete (LMPPRC) with a rapid-set binder. The rapid-set binder was a mixture of rapid-set cement and silica sand, where the fluidity was controlled using a latex polymer. The resulting mix exhibited a compressive strength of ¥21 MPa and a flexural strength of ¥3.5 MPa after 4 h of cur...

Infrastructure systems in the US are in an urgent need of maintenance and rehabilitation. According to the most recent factsheet published by the American Society of Civil Engineers, one of the top five infrastructure concerns of today in the US is transportation systems. The major challenge facing maintenance managers in state Departments of Transportation (DOTs) today is to preserve the road ...

Local Authority road networks commonly include roads with different functional characteristics and a variety of construction types, which require maintenance solutions tailored to their needs. Given this background, on local road network, pavement management is founded on the experience of the agency engineers and is often constrained by low budgets and a variety of environmental and external r...

Plastic is considered one of the most significant industrial inventions this era due to its excellent properties, which lend well many manufacturing applications. These days, there are tons Polyethylene Terephthalate (PET) waste products that generated around world. This presents a real environmental hazard because PET not biodegradable. paper delineates physical and chemical properties justify...

Moisture damage to bituminous pavement occurs via several mechanisms, and appears in diverse forms such as blistering, stripping, and disaggregation. Blistering is a fulminating phenomenon in which the trapped moisture evaporates and upheaves the pavement surface layer within a few hours as a result of so-called blistering heat. In contrast, stripping and disaggregation are types of internal ch...

The objective of this project was to develop a structural index for use in network-level pavement evaluation to facilitate the inclusion of the pavement’s structural condition in pavement management applications. The primary goal of network-level pavement management is to provide the best service to the users for the available, often limited, resources. Pavement condition can be described in te...

The quest for the discovery of mathematical principles that underlie biological phenomena is ancient and ongoing. We present a geometric analysis of the complex interdigitated pavement cells in the Arabidopsis thaliana (Col.) adaxial epidermis with a view to discovering some geometric characteristics that may govern the formation of this tissue. More than 2,400 pavement cells from 10, 17 and 24...
