Abstract

Sardinia is characterized by the production of a large quantity of granite by products. The extraction of granite for ornamental purposes is an important economical resource, but also determines temporary alterations of the landscape and more often permanent waste deposits producing environmental impacts. This paper reports about an ongoing research aimed to re-use granite by products efficiently and in eco-friendly manner to construct unbound pavement layers for rural roads construction durable pavements with re-using disposed materials. The potential application of using granite by-products according to the South African G1 protocol was studied aiming at reducing the environmental impact by reusing granite by products and the thickness of the surfacing bituminous layers. The results reported in this have shown the benefits of constructing unbound granular layer with granite by products for rural road pavements in the terms of mechanical strength, road durability, and economical and environmental impacts.
