HIGUERA-SANDOVAL, Carlos Hernando; ARANDA-LOPEZ, Jeiny Elizabeth  e  PRIETO-HERNANDEZ, José Alberto. Characterization of the Gap Graded Asphalt Mixtures with some Aggregates from the Tunja's City Region. Rev. Fac. ing. [online]. 2014, vol.23, n.36, pp.39-51. ISSN 0121-1129.

The hot Gap graded asphalt mixtures developed in this research, determined their viability to be used in the secondary road transit routes, as an alternative to the asphalt binder and the asphalt base. The aggregates came from two quarries of the Boyaca's Department Central Province, the Recebera Piedra Gorda and La Calera; together with the penetration 60/70's bituminous binder, from IncoAsfaltos S.A., asphalt plant, located in Mosquera (Cundinamarca). For the mix design, were used the Marshall and Ramcodes methodologies. The mixtures dynamic module's determination was carried out by a Nottingham Asphalt Tester (NAT)'s equipment. The results showed higher modules values for the mixtures made with Piedra Gorda aggregates. The pavement structure was designed with La Calera aggregates, in order to meet all specifications.
