Rock aggregates constitute the enormous volume of inert construction material used around the globe. The petrologic description as igneous, sedimentary, and metamorphic types establishes the intrinsic formation pattern of the parent rock. The engineering properties of these rocks vary due to the differences in the transformation process (e.g. hydrothermal deposits) and weathering effect. The two most common mechanical tests used to investigate the performance of aggregates are the Los Angeles (LA) and micro-Deval (MD) tests. This study reviewed the geological parameters (including mineralogy, grain and crystal size, grain shape, and porosity) and the relationship to Los Angeles and micro-Deval tests. It was found that high content of primary minerals in rocks (e.g. quartz and feldspar) is a significant parameter for performance evaluation. Traces of secondary and accessory minerals also affect the performance of rocks, although in many cases it is based on the percentage. Furthermore, some studies showed that the effect of mineralogic composition on mechanical strength is not sufficient to draw final conclusions of mechanical performance; therefore, the impact of other textural characteristics should be considered. The disposition of grain size and crystal size (e.g. as result of lithification) showed that rocks composed of fine-grain textural composition of ≤ 1 mm enhanced fragmentation and wear resistance than medium and coarse grained (≥ 1 mm). The effect of grain shape was based on convex and concave shapes and flat and elongated apexes of tested samples. The equidimensional form descriptor of rocks somehow improved resistance to impact from LA than highly flat and elongated particles. Lastly, the distribution of pore space investigated by means of the saturation method mostly showed moderate (R = 0.50) to strong (R = 0.90) and positive correlations to LA and MD tests.

岩石集料构成了全球使用的大量惰性建筑材料。岩石学上的火成岩，沉积岩和变质岩类型确定了母岩的内在形成模式。这些岩石的工程性质因转化过程（例如热液沉积）和风化作用的差异而变化。用于调查集料性能的两种最常见的机械测试是洛杉矶（LA）和微型测试（MD）测试。这项研究回顾了地质参数（包括矿物学，晶粒和晶体尺寸，晶粒形状和孔隙度）以及与洛杉矶和微时代试验的关系。发现岩石中主要矿物的含量高（例如石英和长石）是评估性能的重要参数。次级和辅助矿物的痕迹也会影响岩石的性能，尽管在许多情况下它是基于百分比的。此外，一些研究表明，矿物成分对机械强度的影响不足以得出机械性能的最终结论。因此，应考虑其他质地特征的影响。晶粒尺寸和晶体尺寸的分布（例如，由于石化作用）表明，由≤1 mm的细晶粒组织组成的岩石比中粒和粗粒（≥1 mm）的岩石具有更高的碎裂性和耐磨性。晶粒形状的影响基于被测样品的凸凹形状以及平坦和细长的顶点。与高度平坦和细长的颗粒相比，岩石的等维形状描述符以某种方式提高了对LA的抵抗力。最后，通过饱和法研究的孔隙空间分布大多显示为中等（R = 0.50）至强（R = 0.90），并且与LA和MD测试呈正相关。
