A: INTRODUCTION The Wisconsin Transportation Technology Transfer Center (Transportation Information Center) has developed a roadway management program for Wisconsin local agencies. This system has been developed in cooperation with local road agency associations and the Wisconsin Department of Transportation. Wisconsin's pavement management system has evolved from a basically paper system devel...

The paper presents results of sensitivity analysis to crack propagation of a pavement bituminous layered structure using the Finite Element Method (FEM) and Artificial Neural Networks (ANN). The performed preliminary study determined stresses and displacements in the pavement layer system. The pavement structure consisting of asphalt layers, a base layer, subbase and subgrade layers was analyze...

This study introduced at first the background of numerous highway widening projects that have been developed in recent years in China. Using a large ground settlement simulator and a fiber Bragg grating (FBG) strain sensor network system, a large-scale model test, with a similarity ratio of 1:2, was performed to analyze the influence of differential settlement between new and old subgrades on p...

Three kinds of epithelial cells comprise the surfaces of the gill filaments and lamellae of larval lampreys (ammocoetes): ammocoete mitochondria-rich cells (AMRCs), intercalated mitochondria-rich cells (IMRCs) and pavement cells. Selected characteristics of these cell types in ammocoetes of Geotria australis held in distilled water and in 10% sea water were compared using an ultrastructural ste...

Stormwater quantity control is an important issue that needs to be addressed in roadway and ancillary transportation facility design. Pervious concrete has provided an effective solution for storm runoff for parking lots, sidewalks, bike trails, and other applications. It should be readily adaptable for use on roadway shoulders. Being a relatively new material for use in pavement for roadways, ...

BACKGROUND Walking for physical activity is associated with substantial health benefits for adults. Increasingly research has focused on associations between walking behaviours and neighbourhood environments including street characteristics such as pavement availability and aesthetics. Nevertheless, objective assessment of street-level data is challenging. This research investigates the reliabi...

In this work we model an inductive loop detector with the purpose of studying the influence of significant vehicle characteristics on the obtained inductive signatures. Since this model will allow us to obtain the vehicle inductive signatures by means of a simulator without making use of expensive, not only in time but also in resources, tests in real scenarios, we will have a powerful tool to ...
