    Cold mix asphalt with polymeric stone for low traffic volume roads
    (2023-07-30) Rivera, José Julián; Battista, Nicolás Daniel; Oviedo, Adrián Mariano; Rebollo, Oscar Raúl; Zapata Ferrero, Ignacio; Fensel, Enrique Alberto; Delbono, Héctor Luis; Martínez Reguero, Adriana
    The use of polymer-based household waste in the wearing course of flexible pavements has been analysed, either as an asphalt bitumen modifier or as a dry additive. However, there are not enough records in which this waste is used to make up the aggregate to be used in an asphalt mix. This article presents the development carried out at LEMaC, consisting of pieces made from the mixture of household waste polymers and soils, which has been called Polymeric Stone. This material is used to design a cold-mix asphalt, and its use has been validated after evaluating a series of properties.

    Method to determine the dosage of bituminous tack coat in function of the texture of milled asphalt layers to be overlaid
    (2019) Rivera, José Julián; Bianchetto, Hugo Daniel; Martínez Reguero, Adriana
    In the rehabilitation of flexible pavements with asphalt layers, it is necessary to apply a bituminous tack coat with a pre-established dosage, which usually does not take into account the degree of texture generated if a milling operation is previously performed, since this increases the surface at the interface. On the other hand, when milling, grooves are obtained that could lead to the runoff of bitumen emulsion with excessive deposition in their valleys due to dosages greater than those needed. This work analyzes the above mentioned and achieves a compromise solution, with its corresponding method of application, based on the mechanical behavior obtained with different degrees of texture and validated for typical materials used in Argentina.
