Asphalt concrete made with RAP with the addition of PG 70-16 Asphalt

The present investigation presents the characteristics of samples of recycled asphalt pavement (RAP) as recovered in the field.The RAP was recovered from the Tampico-Mante highway in Altamira Tamaulipas to be characterized in the materials laboratory and compared with the quality standards for asphalt mixtures of the Secretariat of Communications and Transportation (SCT). Subsequently 1 2 3 and 4 % by weight of asphalt cement grade PG 70-16 was added to make specimens and their characterization following the guidelines of a Marshall design performing tests of granulometry asphalt content specific weight flow and stability with the purpose of evaluating the compliance with the standard N-CMT-4-05-003/16 Quality of Asphalt Mixtures for Roads of the SCT.Key words: RAP recycled pavement asphalt asphalt mixtures.
