Abstract
Beginning during the decade of 1920, the Brazilian highway system became the main way of transportation in the country, fomenting the search for asphaltic mix with better mechanical properties and resistance to the weather variations. The asphaltic mix is formed by minerals aggregates and binder (PAC Petroleum Asphaltic Cement). The aggregates are responsible for supporting the traffic weight and stability. The PAC is responsible for the attachment between the constituent particles and impermeable state. In this work it was investigated the formulation of asphaltic mix starting from the packing equations of the particles: Andreasen, Alfred and Alfred Inverted. It was produced bodies of proof varying the proportions of the aggregates and fillers, keeping constant the PAC (5% in weight) and the results were compared to an industrial standard formulation. The values obtained are in accordance with the DNIT norms, indicating that the equations of packing can be applied to the formulation of asphaltic masses.
