Retraction Note: Prediction of aggregate modified index (AMI) using geomechanical properties of limestones

Limestone aggregates are considered as construction materials with special suitability for use a part of base courses, asphalt and Portland cement concrete. The different applications is determined by aggregate parameters including the Los Angeles abrasion value (LAAV), impact (AIV), crushing (ACV). In this paper, combination all these presented an index (AI); Hamedan Limestones were classified based on new index. physico-mechanical properties can also be used to evaluate their any specific engineering application; therefore, rock samples measured. AI was modified using p-wave velocity parameters, changed into (AI/V p = AMI). Statistical analyses, simple multiple regressions, applied offer some rational approaches identify those that more appropriate prediction AMI. Consequently, velocity, uniaxial compressive strength, dry density Brazilian tensile strength show significant correlations AMI at α-level = 0.1.
