Poor adhesion between two successive bituminous layers causes adverse effects on the structural strength of the pavement and develops a numbers of premature failure. To improve the adhesion, it is a general practice to apply a tack coat over an existing or newly constructed bituminous surface before laying another bituminous layer. The main objective of this study is to explore the influence of...

The objective of the present paper is to examine effect Recycled Asphalt Pavement (RAP) on marshall properties and indirect tensile strength HMA through experimental investigation. A mixture with 0% RAP was used as a control mix evaluate mixes 5%, 10%, 15% RAP. One type brought from Bab Al-moadam’s road in Baghdad for this purpose. testing program included Marshall Indirect Tensile Strength tes...

This paper presents parts of the results from a research project sponsored by Taiwan Environmental Protection Administration (TEPA), investigating both the physical and environmental properties of asphalt mixtures using different amount of incinerator bottom ash (IBA) as fine aggregate substitution. The Marshall mix design method was used to determine the design asphalt content and evaluate the...

Abstract: In this paper we consider various Marshall-Olkin distributions and develop autoregressive minification processes with stationary marginals as exponential, Weibull, uniform, Pareto, Gumbel, Lomax etc. The applications in reliability modelling and stress-strength analysis are considered.Problems of estimation of parameters is addressed. Various properties are examined. Modelling with re...

In this paper, we consider the reliability of k-out-of-n: F systems and its conditional form with exchangeable components in the stress-strength setup. We assume a random stress common to all the components in the system level. Applications of these results to illustrate the reliability for the system consisting of three components with the multivariate FGM and multivariate Marshall-Olkin distr...

Damage to asphalt construction has made several attempts increase the strength of construction, one which is by utilizing shell waste as an mixture (filler) expected and durability pavement. The addition filler with varying levels 0%, 5%, 10%, 15%, 20%, 25% taken from percentage fine aggregate. Based on results research conducted, Marshall Test for mixtures best variations material meeting requ...

Building upon previous projects from the first phase of collaboration with the Luce Foundation, the Berkley Center’s Religion and Global Development Program and World Faiths Development Dialogue (WFDD) are exploring key religion and development work at the country level in Bangladesh, Senegal, Kenya, and Guatemala. A team of researchers, under the leadership of Katherine Marshall, will draw fro...

Justin Marshall is Professor of Neurobiology and Marine Biology at the University of Queensland in Australia within The Queensland Brain Institute. He can be labelled a visual ecologist as he studies comparative eye design and how this is guided by the physics of light. He has co-written a book called “Visual Ecology”, co-edited a book called “Sensory Processing in Aquatic Environments”, is co-...

Using Reclaimed Asphalt Pavement (RAP) in asphalt mixes has become a common practice in many countries as experience indicated that the recycling of asphalt pavements is very advantageous from different perspectives. Some of the advantages of utilizing RAP include conservation of asphalt and aggregate resources, conservation of energy, and reduction in life-cycle cost. In this study, the suitab...
