The use of carbonate rocks is important worldwide due to their utility in various fields. However, their physical and mechanical characterization can determine their fields of application and their economic interest. The establishment of these properties allows the assessment of their economic importance and future use. Uniaxial compressive strength (UCS) is one of the most important mechanical properties used to test carbonate rocks. Los Angeles (L.A) and Micro-Deval (MDE) coefficients are essential properties used to verify the mechanical resistances of the aggregate to be used on roadways. Analyzing these mechanical parameters determine the economic interest of rocks. The purpose of this project is to explore additional carbonate resources in Tunisia, even when the determination of some parameters is not possible. For this purpose, 30 samples with different physical and mechanical properties were chosen from 8 different sites. Two of them are well known in Tunisia: one is exploited to extract aggregates of good mechanical resistance, and the other is exploited for marble stone mining. Laboratory test results show that many unexplored sites harbor rocks with good qualities which could be exploited in different applications. UCS, LA and MDE coefficient values show new good quality carbonate-rock resources. The results determined the physical properties of studied rocks to conclude the potential use of each rock and to estimate the parameters for which the measurements are not possible.

由于碳酸盐岩在各个领域的实用性，因此碳酸盐岩的使用在全球范围内都很重要。但是，它们的物理和机械特性可以决定其应用领域和经济利益。这些属性的建立可以评估其经济重要性和未来用途。单轴抗压强度（UCS）是用于测试碳酸盐岩石的最重要的机械性能之一。洛杉矶（LA）和微位移（MDE）系数是必不可少的属性，可用于验证要在道路上使用的骨料的机械阻力。分析这些机械参数决定了岩石的经济利益。该项目的目的是即使在无法确定某些参数的情况下，也要在突尼斯探索更多的碳酸盐资源。以此目的，从8个不同地点选择了30个具有不同物理和机械性能的样品。它们中的两种在突尼斯是众所周知的：一种被用来提取具有良好机械抗性的骨料，另一种被用于大理石石材的开采。实验室测试结果表明，许多未勘探的地点都拥有质量优良的岩石，可以在不同的应用中进行开采。UCS，LA和MDE系数值显示出新的优质碳酸盐岩资源。结果确定了所研究岩石的物理性质，从而推断出每种岩石的潜在用途并估计了无法进行测量的参数。另一个则用于大理石石材的开采。实验室测试结果表明，许多未勘探的地点都拥有质量优良的岩石，可以在不同的应用中进行开采。UCS，LA和MDE系数值显示出新的优质碳酸盐岩资源。结果确定了所研究岩石的物理性质，从而推断出每种岩石的潜在用途并估计了无法进行测量的参数。另一个则用于大理石石材的开采。实验室测试结果表明，许多未勘探的地点都拥有质量优良的岩石，可以在不同的应用中进行开采。UCS，LA和MDE系数值显示出新的优质碳酸盐岩资源。结果确定了所研究岩石的物理性质，从而推断出每种岩石的潜在用途并估计了无法进行测量的参数。
