Evaluation of Recycled Aggregate (RAP) Presence Impact under Indirect Tensile Strength of Bitumen Stabilized Mix with Foamed Asphalt for a Base Layer

Abstract:

Foamed bitumen improves the properties of base layer, increasing the number of equivalent axles allowed, as result of this is a durable pavement. To achieve this, base layer’s design must count with an amount of filler, to increase the stony aggregate fraction. This research consists with two different types of filler, lime and cement, 1% in dosage respect to the stony aggregate weight. Has been discovered now, that the RAP (reclaimed asphalt pavement) aggregate in addition to mitigate environmental problems, has a significant impact value on the mechanic resistance of the mix.
