Abstract

In this contribution, 10,000 tonnes of marble waste dumps have been characterized in order to define the physico-mechanical and mineralogical parameters and determine their feasibility to be applied as main components in road bases and sub-bases. The Los Angeles abrasion values obtained (41-53%) exceeded those permitted for the standard technical specifications. However, particle-size distribution, plasticity and California Bearing Ratio (C.B.R.)(76, 83, 100% at 97, 98 and 100% of maximum density, respectively) satisfied, marginally, those specifications. Therefore, with a simple screening, these waste dumps would be applied as granular materials in roads. This is an alternative: a) environmentally sustainable, since future crushed stone exploitations would be reduced and removed a potential environmental passive; b) technically feasible, because the carrying capacity of the granular layers would not be affected; and c) economically profitable, because adds value to a currently non useful material and reduces the extraction and transportation costs.

评估大理石废料作为路面结构骨料的使用，cordoba，阿根廷

在这份报告中，对10 000吨大理石废料堆进行了特征分析，以便确定其物理力学和矿物学参数，并确定其作为道路基础和次级基础主要组成部分的可行性。获得的洛杉矶磨损值(41-53%)超过了标准技术规范允许的值。然而，粒径分布、塑性和加州承载比(C.B.R.)(分别在最大密度的97、98和100%时为76、83、100%)略微满足这些要求。因此，通过简单的筛选，这些垃圾场将作为颗粒材料应用于道路。这是一种替代方案:a)环境可持续，因为未来的碎石开采将减少，并消除潜在的环境被动;B)技术上可行，因为不会影响颗粒层的承载能力;c)经济上有利可图，因为增加了目前无用的材料的价值，降低了提取和运输成本。
