“…According to Table .1 , limestone samples in the study area can be compared with limestone samples from different well-known limestone deposits in Pakistan. Physical and strength tests on aggregates from the Wargal Limestone and Chhidru Formation yielded findings that were equivalent or parallel to those found in other investigations 5 , 21 , 23 , 42 , 61 . Aggregates with high strengths tend to have low soundness, abrasion value, impact value, crushing value, and porosity whereas lesser strength aggregates have greater soundness, Los Angeles abrasion value, aggregate crushing value, and aggregate porosity 5 , 62 – 64 .…”

The China-Pakistan Economic Corridor (CPEC) is an ongoing mega-construction project in Pakistan that necessitates further exploration of new natural resources of aggregate to facilitate the extensive construction. Therefore, the Late Permian strata of Chhidru and Wargal Limestone for aggregates resources were envisaged to evaluate their optimal way of construction usage through detailed geotechnical, geochemical, and petrographic analyses. Geotechnical analysis was performed under BS and ASTM standards with the help of employing different laboratory tests. A simple regression analysis was employed to ascertain mutual correlations between physical parameters. Based on the petrographic analysis, the Wargal Limestone is classified into mudstones and wackestone, and Chhidru Formation is categorized into wackestone and floatstone microfacies, both containing primary constituents of calcite and bioclasts. The geochemical analysis revealed that the Wargal Limestone and Chhidru Formation encompass calcium oxide (CaO) as the dominant mineral content. These analyses also depicted that the Wargal Limestone aggregates bear no vulnerability to alkali-aggregate reactions (AAR), whereas the Chhidru Formation tends to be susceptible to AAR and deleterious. Moreover, the coefficient of determination and strength characteristics, for instance, unconfined compressive strength and point load test were found inversely associated with bioclast concentrations and directly linked to calcite contents. Based on the geotechnical, petrographic, and geochemical analyses, the Wargal Limestone proved to be a significant potential source for both small and large-scale construction projects, such as CPEC, but the Chhidru Formation aggregates should be used with extra caution due to high silica content.

“…The main purpose of this test is to assess the petrographic analysis of specific grades of asphalt in terms of adhesive properties at a constant temperature of 25°C [1]. The chemical configuration of the aggregate surface and the degree of roughness significantly impact the nature of the asphalt aggregate bond.…”

“…Pakistan is abundant with limestone aggregates, produced by crushed intact rock. Margala hill Limestone, Kirana hills aggregate, Khyber Limestone, Wargal Limestone, Skaser Limestone, Kohat Carbonates are the major source of aggregate in Pakistan [1,[11][12][13]. These aggregates were utilized by the National Highway Authority (NHA) for the construction of highways, under China-Pakistan Economic Corridor (CPEC) mega project.…”

The China-Pakistan Economic Corridor (CPEC) is a massive in-progress construction project in Pakistan that connects more than 70 countries via multiple trade channels such as highways, railways, roads, and fiber optics. This project also involves the development of local infrastructure and industrial zones in Pakistan, which demands the discovery of new resources of aggregate to facilitate the construction. Therefore, physical characterization research was carried out on the Kirman hill region (Jurassic limestone), District Kurram, Pakistan, to investigate their suitability for utilization as construction materials using site investigation and laboratory studies. The results outline that all typical engineering parameters are within acceptable limits set by international standards like BS, ASTM, and AASHTO. Bituminous tests revealed that Jurassic limestone is appropriate as an aggregate for asphalt wearing coarse. Likewise, the petrographic study performed shows proper matching with engineering tests. The petrographic analysis of Jurassic limestone showed a minute amount of deleterious content; as a result, it is resistant to Alkali silica reaction (ASR) and Alkali carbonate reaction (ACR) expansions. Based on engineering and petrographic analysis, the Jurassic limestone, Kirman hill region, District Kurram, Pakistan is recommended as a potential aggregate for (i.e., base course, subbase course, cement concrete, and asphalt) and other mega and minor civil construction projects.
