The number of commercial vehicles using Irish roads has increased considerably in recent years, leading to higher demands being placed on pavement materials and increased use of polymer modified bitumens. This has also coincided with significant changes in Governmental policy which has produced large increases in Irish recycling rates. Improved recycling levels are set to provide Ireland with a newchallenge: to find potential uses for the large quantities of recycled polymer that are becoming av ...[more] |

Round Robin Test SPB measurements : final report / A. Bergiers
Brussels : BRRC, 2010
For the revision of standard ISO 11819-1 “Statistical Pass-By method”, which is currently ongoing, ISO/TC43/SC1/WG33 would like to include a method to measure the acoustical quality of a road in a built-up urban environment. The adapted conceived method is called “Backing board method”. Different experiments were performed within the European SILENCE project to assess the accuracy of ...[more] |

In recent years, several tests have been conducted with additives to road salt (such
as agricultural bi-products), with one of the purposes being reduction of the amount of salt used for winter maintenance. The Norwegian Public Roads Administration seeks to optimize salt usage in winter maintenance in order to minimize environmental impacts. In this respect there is a need for a better understanding of
how road salt additives can reduce usage of road salt. Focus is directed to the extension of ...[more] |

The time spent searching for free parking spaces can produce considerable environmental pollution. Information on parking availability can be a powerful instrument for reducing these search costs. This paper develops a demand assignment model to evaluate the benefits of manipulating information with the objective of reducing the time and distances involved in finding a parking-place; including the walking distances involved. Using the full search procedure it was found that improvements of some ...[more] |

Vegetable oils have been studied as a feasible substitute for diesel fuel, and short term tests using neat vegetable oils have shown results comparable to those of diesel fuel. However, engine problems arise due to the high oil viscosity after long-term usage. Vegetable oil/diesel blending as biodiesel fuel has been shown to be one technique to reduce vegetable oil viscosity. The goal of this research is to demonstrate the feasibility of producing this biodiesel fuel via vegetable oil extraction ...[more] |

Since ethanol is a renewable source of energy and has lower carbon dioxide (CO2) emissions than gasoline, ethanol produced from biomass is expected to be used more frequently as an alternative fuel. It is recognized that for spark ignition (SI) engines, ethanol has the advantages of high octane and high combustion speed and the disadvantage of ignition difficulties at low temperatures. An additional disadvantage is that ethanol may cause extra wear and corrosion of electric fuel pumps. On-board ...[more] |
