Analysis of bituminous pavements with artificial and recycled aggregates on sustainable roads
Abstrak
Abstract This research carried out compares the behavior of traditional bituminous mixes with other sustainable mixes reusing recycled materials, waste or additives that improve mechanical or rheological characteristics. We have obtained the stresses and deformations in the pavement sections analyzed and the fatigue laws, determining the number of 13t axles that the material can support. For Heavy Vehicle (HV), with an Annual Average Daily Heavy Traffic (AADHT) of at least 800 HV by day (HV/d), the mixes investigated show a section durability loss of 12-15%, which can be considered acceptable. However, for minor traffic, for AADHT up to 25 HV/d, all the sustainable mixes tested improve the durability of the traditional mixes. However, for traffic below 25 HV/d, the data obtained do not recommend the use of sustainable materials in the case of a single pavement layer. As a wearing course, they can be laid in cycle paths or pedestrian areas.
