The optimization of road networks maintenance costs has increased its relevance during the last years due to the need for maximizing the use of the available economic resources. According to that, the County of Valladolid has been applying during the last years innovative tools in order to increase the level of precise and objective information to improve the maintenance activities of traffic signs and pavement markings along its road network. Following the above target, it has started to use dynamic survey technologies to inspect retroreflectivity levels for traffic signs and pavement marking, so that reliable information can be gathered safely in shorter periods of time. All the information that can be obtained, compiled within a specific inventory, is allowing to perform an optimized management of these elements as well as to carry out a fast and simple update of the signs and markings performance.

Dam Maintenance and Rehabilitation II - Proceedings of the 2nd International Congress on Dam Maintenance and Rehabilitation | Year: 2011

Proserpina Dam is a construction of clear Roman origin, related to water supply to the ancient Emerita Augusta. When this use was lost, the dam continued in service, its water being used for various purposes. This has involved the ongoing maintenance of the dam, with multiple performances which are only documented from the sixteenth century on. In the mid of twentieth century, the dam is put into use by the State Hydraulic Services, and in the decade from 1990 to 2000 are made important works on the dam. Recently the State Hydraulic Services (Guadiana river basin Authority and Ministry of Environment) are conducting a comprehensive rehabilitation of the dam and its environment, improving their safety and facilitating functionality and sightseeing, actions which are described in this paper. © 2011 Taylor & Francis Group, London.

In the Gudajira river basin there are two old dams, "Albuera del Castellar", wich could be of the first of the XVI century, and "Albuera de Feria" of mid XVIII century. In the second half of the XX century was built "Zafra" dam, wich immerses "Albuera del Castellar", and "Jaime Ozores" dam, wich together with "Albuera de Feria" gives water to a pool of supply. Actually, water supply to that pool is problematic due to the low capacity of both reservoirs, so it was decided to built a new dam, "Villalba de los Barros" dam. It is an embankment dam, 45 meters height, creating a reservoir of 106 hm 3. This will ensure the supply to the pool and some other villages, besides allowing some irrigation. The dam is currently under construction, highlighting the environmental monitoring of the works, conducted by the University of Extremadura, and the emergence of several archeological sites in the reservoir area.

Roads passing through built-up areas give rise to myriad conflicts between road users on one hand and the resident population on the other. Accordingly we need to find a method to allow us to consider which of the most problematic throughtraffic routes need to be replaced by bypasses, and among these, which should be built with highest priority. This paper sets out the methodology developed and used by the Castilla-León Directorate General for Roads and Infrastructure so as to ascertain what the needs really are and to articulate a proposed scheduling of such work. It is a simple, easily computerised system which, according to the most characteristic data in each section (traffic, number of inhabitants, accident rate, etc.) assesses each through-traffic route so as to determine if its replacement with an alternative route (bypass) is strictly necessary and what degree of priority should be assigned to the replacement, on the basis of an objective scoring from 1 to 100. Economic criteria are left out of these considerations, as needs are not linked to costs or cost-effectiveness. That is an issue for separate and in all events subsequent discussion.

This article presents the methodology, calculations, results and conclusions of a study on Strategic Noise Maps (SNMs) on roads with a traffic flow of more than 6 million vehicles a year, adopted by the Resolution of 23 December 2009 of the Cantabrian Department of Public Works, Spatial Planning, Housing and Urban Development, and implemented within the Cantabrian regional road network. As is to be expected, these "road arteries" are mainly located in the vicinity of the towns in the region with most population and industry, which causes there to be a considerably higher volume of daily traffic on such roads, without forgetting the other key factor that is tourism, which in summer also results in high pressure on the road network, especially in coastal areas. Thus taking Cantabria's Regional Road Network Capacity Plan as a reference, and in keeping with Law 37/2003 on Noise, strategic noise maps were produced on a total of five roads: CA-231-1, Santander-Liencres-Puente Arce; CA-140-1 and 2, Muriedas-EI Astillero; CA-130-1 and 2, Cajo-EI Empalme-Peñacastillo; CA-131-1, Barreda-La Revilla and CA-132-1 and 2, Viveda-Suances, specifically following all the aspects provided in Royal Decree 1513/2005 on environmental noise assessment and management. The study's findings regarding population affected by noise, in hundreds, were a total of 64 for levels of 55-59 dBA, 40 for 60-64 dBA, 28 for 65-69 dBA, 18 for 70-74 dBA and 7 for values in excess of 75 dBA, all linked to the overall annoyance indicator (Lden). If these findings are crossed with the total population in Cantabria, a rate of 1.10% is not exceeded in any event, and the largest affected area (Lden>55 dBA isophone) is less than 4.5 km2.

This article presents the acoustic analyses conducted on the recycled paving used in the project for the "Improvement of the platform of roads CA-234, CA-332 and CA-334, Section: Renedo-Zurita-Sierrapando-Las Presillas" in accordance with the prescriptions of the SPB, Statistical Pass-By Method, a fully standardised model according to UNE-EN ISO 11819-1 "Measuring of the influence of road surfaces on traffic noise. Part 1: Statistical Method of Vehicle Pass-By". Part of the study is also based on the comparison between two different road surfaces: 'recycled asphalt agglomerate' to which reference is made and 'conventional asphalt agglomerate', widely used in the Road Network of the Autonomous Region of Cantabria in recent years. For the latter comparative analysis, road CA-148, section Gama-Argorios has been chosen owing to its similar characteristics in regard to the surfacing being analysed and its perfect adjustment to the guidelines and requirements of the UNE Norm used. Derived from the meticulous application of the standardised method of reference, fairly reliable conclusions have been obtained which indicate a substantial diminution in the noise levels emitted by the recycled paving in comparison with conventional paving (≈2,6 dBA). However, other considerations taken into account relate to the need to conduct new studies, necessarily on the surfacing under analysis (recycled paving) with the purpose of discovering the acoustic performance of this same surfacing over the years.

This article tries to give the reader a clear view of the initiatives (in road safety) that are being taken in the regional government of Extremadura. While there are other pioneering administrations in this field, we have taken up the torch and, today, we are engaged in developing an ambitious program of road safety. The main measures are proving highly effective in relation to the decrease of the accident rate. In order to assess the validity of the initiatives proposed, in February 2012, was created the Regional Observatory for Road Safety meeting forum where knowledge and experiences are shared and where an assessment and analysis of registered accident rates and as monitoring of road safety management developed through writing projects and implemented, ongoing or planned works. It Includes interventions of different experts and contributions to the improvement of security are provided from different approaches, such as relevant studies in scope or new initiatives, proposals, legislation updates, etc., some of which are directly promoted by the general director.
