Abstract-Since highways are widely used modes, it is necessary that it should be maintained properly. Subgrade being the support for the whole pavement, it needs the utmost care in its construction. Many suggestions have been put forward by various scientists to improve the subgrade. The usually adopted methods are stabilization methods. This paper deals with the improvement of properties of ka...

Introduction: More than 80 fossil meteorites have been found in the ~4 m quarry layer of midOrdovician marine limestone in southern Sweden (Thorsberg quarry) [1, 2]. The analysis of noble gas data [2] in chromite grains from these meteorites has revealed a clear negative correlation between He, Ne concentrations and mass of the samples [3]. Similar correlation has been found also for cosmicray ...

The purpose of this study is automated handling of massive rocks for moving them to a proper place and for breaking them down at a rock quarry. This paper reports our first approach in laboratory environment using a robotic manipulator with a small sized laser range finder(LRF) to handle a relatively small object. For tumbling operation, we apply image processing techniques onto range images cr...

This paper reports on the unsupervised analysis of seismic signals recorded by four stations situated on the Vesuvius area in Naples, Italy. The dataset under examination is composed of earthquakes and false events like thunders, quarry blasts and man-made undersea explosions. The goal is to use these specific data for comparing the performance of three projection methods that are well known to...

In this study, the process of anthropic decay on stone materials and on the lithobiontic microbial colonization associated was investigated by means of both laboratory simulation (granite) and field experiments (dolostone ́s historical quarry), all of them stone materials traditionally used in heritage construction. A wide variety of salts including sulphates, phosphates and chlorides resulted f...
