The paper presents a study, on several samples of asphalt mix, with different compositions, in order to investigate the influence of the composition, on the properties, which asphalt mix must fulfil. For all kinds of aggregates, the granulometric analysis was made, and the bitumen content was varied, to study the influence on the properties of the mixture.

The optimization of the solidification of the cast parts is based on the exact knowledge of the solidification mode of the part. The only solution for the rapid, and low-cost, optimization of technological problems related to the solidification of castings is the computer simulation of solidification. The solidification of castings from metal alloys is a complex physico - chemical process, which has a great influence on the quality of castings. The optimization of the solidification process of the castings has a direct influence on the consumption of liquid alloy, labor and energy. This is explained by the reduction of the percentage of waste and specific consumption. In these paper, the programs applied for optimizing the technology for making the landmark are MAGMA and Click2Cast.

The paper presents an analysis of the soil quality, in the petroleum field from Independenta, Galati. The study was determined by the fact that the hydrocarbon spills from the activity carried out here can have a significant impact on the environment. The paper presents the determinations carried out on soil samples related to heavy metal content and pH. Samples were taken from different areas, starting from a contaminated source, and continuing with the surroundings. For each area, three samples were taken at different levels of depth. Concentration values were compared with the legislation [1] setting out the procedures and technical rules for identifying environmental damage in order to determine the responsibilities for remedying them.

In this is paper present the calculation of the overall risk level for workplacedriver. Risk assessment is the first step towards safer and healthier jobs, and it is the way to reduce accidents at work and occupational diseases. The new trends in managing an organization are to consider as performing an organization that is equally concerned with improving the quality of products / services and increasing economic efficiency, as well as providing adequate working conditions for employees and environmental protection environment, by increasing the quality of life in general. All of these components are addressed within integrated management systems, which usually aim to organize the operation of companies. Employee health and safety, protection of neighbouring populations, flora and fauna, water and soil are just as important as the organization's profit. But what does the health and safety component of work in this integrated system involve? The increase in profit results from the reduction of material losses due to accidents and damages, the reduction of absenteeism due to medical leave, the elimination of losses caused by penalties resulting from non-compliance with legal requirements, etc.
