    Quality Control of Bituminous Mixtures Through the Indirect Tensile Strength Test. Experiences in Spain and Argentina

    Quality Control of Hot Mix Asphalt Production in both Argentina and Spain is carried out by evaluating the mixture composition and the parameters obtained according to the Marshall method. Once the asphalt mix is placed and compacted, quality control consists of extracting core samples to determine their thickness and density. This methodology, however, does not take into account the mechanical performance parameters of the asphalt layer once it has been executed.

    For this reason, a research project has been developed at the Roads Laboratory of the Universitat Politècnica de Catalunya, based on the application of the Indirect Tensile Strength (ITS) test on core samples extracted from the pavement. Based on the results obtained, an acceptance criterion for bituminous mixtures has been proposed that allows for the evaluation of their mechanical quality, not merely their compaction.

    Currently, a study is being conducted at the Pavement and Road Engineering Laboratory of the Universidad Nacional de La Plata, in collaboration with the Transportation Infrastructure Area of the Universidad Nacional del Comahue, aimed at assessing the potential implementation of this method in Argentina.

    This paper presents the aforementioned proposal and provides an analysis of the results obtained in both countries.

    Experiences with the Falling Weight Deflectometer (FWD) Used for Construction Quality Control of the Different Pavement Layers

    Given the difficulty in securing budgets in Colombia, along with the lack of a maintenance-oriented culture among government agencies, it becomes imperative to execute road construction works with total quality. In order to achieve this total quality, it is essential, among other factors, to carry out thorough quality control at each stage of the pavement construction process.

    How much is road infrastructure worth?

    In general, drivers and pedestrians use roads, bridges, sidewalks, intersections, traffic lights, informational signs, and other elements without realizing how much their construction and maintenance have cost the country. It is only occasionally, such as when a user reaches a toll booth on a highway, that they are directly confronted with the reality that road infrastructure has a cost that society as a whole must finance or pay in order to benefit from its service.

    Origin of the Duality of an Argentine Road Sign

    The advent of the motor vehicle has caused an explosive growth in traffic flow on the roads and a notable increase in speed. These circumstances generated the need to rationalize the road signage system, which, with a universal character, would be understandable to all road users anywhere in the world.
