Article
Rockfalls on transport infrastructures are a serious hazard to users and many resources are invested in rock slope maintenance, stabilization, and protective measures. In volcanic territories, the risk of rock instabilities and rockfalls is very high due to the rugged natural slopes and origin of rock masses. With the aim of determining the influen...
Article
In volcanic terrains and in particular island regions, the aggregates come from the mechanical crushing of lava rocks and pyroclastic deposits. This study offers an experimental database of the geomechanical characteristics of different volcanic rock lithotypes and the aggregates obtained from these rocks. For this purpose, 971 aggregate samples an...
Article
The main volumetric and engineering characteristics of hot mix asphalt with crumb rubber modified bitumen from used tyres and high-porosity volcanic aggregates are presented and compared to the same mixtures with conventional bitumen. In volcanic territories, these marginal aggregates are the most common lithotypes and environmental protection cond...
Article
This study presents the results of the principal engineering properties of asphalt-rubber warm mixtures (AR-WMA) with waste crumb rubber from used tyres and highly-vesiculated basalt of scoriaceous nature, also considered a residual or marginal aggregate according to standard specifications. The temperature reduction was carried out using a liquid...

This article outlines the ultrasound data employed to calibrate in the laboratory an analytical model that permits the calculation of the depth of partial-depth surface-initiated cracks on bituminous pavements using this non-destructive technique. This initial calibration is required so that the model provides sufficient precision during practical...
Conference Paper
This study presents a geomorphologic review of the northern sector of Anaga Massif in order to establish a relative sequence of geomorphic processes. The present-day relief shows a polygenic nature, combining fluvial erosion with other prior erosive processes. The analysis of slopes and watersheds suggests the existence of an active instability pro...
Conference Paper
Open image in new windowRockfalls on roadways are a serious hazard to users. Many resources are invested in rock slope maintenance and measures of stabilization and protection to mitigate the risk. Catchment areas (ditches) are one of the least expensive and most effective protective measures to contain and restrict rockfall onto roadways. While th...
Conference Paper
Open image in new windowThe costs associated with rockfall risk are high. Many resources are invested in rock slope maintenance and stabilization, and protection measures to reduce rockfall hazards on transport infrastructures. However, few studies aim to evaluate the relative influence of the different factors (geometrical and material properties)...
Conference Paper
Los áridos son uno de los materiales básicos más importantes de la industria de la construcción. Junto con el agua, constituye uno de los dos productos de mayor consumo per cápita en el mundo y una de las cuatro materias primas más importantes de la producción minera mundial después del petróleo, el gas y el carbón. Una de las peculiaridades de los...

The current work analyze 5 factors that define the stop distance of falling rocks: block shape (F ), block size (T), talus height (H ), talus slope (H:V) and ditch inclination (H:V). The principal goal is to determine the influence of each factor to improve the territory planning decisions. We conclude that the lithology is a significant factor of...

In volcanic territories, such as many island regions with this geological origin, the risk of rock instability and rockfalls on transport infrastructures is prominent because of both topographical and lithological factors. The rugged natural relief makes it necessary to design roads and railways with limited width and steep adjacent slopes. The lithological characteristics, origin of rock masses, and even seismicity result in rock slopes with abundant potentially unstable blocks. The use of catchment areas to reduce the hazardous consequences of rockfalls on transport infrastructures is a simple, economic and effective measure. It also means low environmental impact and easy maintenance. In fact, this is a competitive solution compared to stabilization structures requiring important financial investment. Catchment areas are therefore an ideal method for protection of infrastructures in developing countries or with limited economic resources. This study offers a useful tool to optimize the slope-bench-ditch system design, permitting easy evaluation of its retention capacity at the planning stage or even when built, and justification of any possible improvements.
