The Use of Milled Material Mixtures in Urban Pavements – First Experiences In Sao Luís – MA - BR

Waste materials from milling services in major urban roads in Sao Luis, Maranhao, in the Northeast of Brazil, are being deposited on the municipal’s asphalt plant. Local engineers have no experience on using milled materials, except for its use in filling up potholes. Due to environmental impacts and the limited availability of materials for pavement construction in the region, it’s necessary to make the best use of this material. The present paper describes a research conducted with milled material, which was obtained from asphalt concrete and sand asphalt wearing courses. Three types of mixtures were considered to be used as base layers: milled material + crushed stone and milled material + soil or even only milled material. These mixtures are compared with lateritic gravel, normally used as base material. Laboratory tests like resilient modulus, compression strength and permanent deformation were conducted to characterize these materials. Results intend to provide guidance towards finding compatible solutions, considering the base material, the pavement structure and the type of traffic supported, while giving appropriate destination to the waste material.
