| Descripció: | This article describes the execution of both destructive and non-destructive dynamic laboratory tests on a porous asphalt material modified with recycled polyethylene strips derived from milk bags, with the objective of determining its properties and optimal temperature range for use. The plastic material was introduced into the asphalt mixture during the blending of the aggregate and asphalt, in strips approximately 40 mm x 50 mm in size. Dynamic modulus tests were carried out at 10, 20, and 30°C, and at frequencies of 1.6, 2.5, and 5.0 Hz. Fatigue laws were evaluated at three different strain levels and at temperatures of 15, 25, and 35°C. Rutting tests were performed using the LCPC (Laboratoire Central des Ponts et Chaussées, France) methodology at 60°C and 42 rpm. The main results obtained included the optimal temperature ranges for using the material, as well as the improvement percentages in its rheological and drainage properties. |
