Abstract:
Single toggle jaw crushers are widely used in mining and aggregate industries, but they suffer from significant liner wear, leading to increased maintenance costs and downtime. This research investigates the impact of a novel single toggle jaw crusher design with a passive displacement fixed jaw on liner wear. The investigation was done by carrying out a comparative analysis between the conventional jaw crusher design and the new jaw crusher design. During the evaluation of the conventional and new crusher designs, the liners were initially weighed with an electronic scale of 20 g sensitivity,

Hydrated Cement Treated Crushed Rock Base (HCTCRB) is produced by mixing a standard crushed rock base with 2% cement (by mass) and water then a re-mixing process is performed after the specific hydration period. This technique improves the engineering characteristics of the materials while still maintain the unbound properties. Performance evaluation of HCTCRB was investigated with variation of factors during manufacturing and construction. Finally, the experimental results were implemented for the pavement analysis and design.

ABSTRACT Crushed salt may be used as backfill material and sealing measures of open cavities, drifts and shafts in nuclear waste repositories located in rock salt formations. The host rock salt will gradually compact the crushed over time due to salt creep. A comprehensive understanding of the crushed salt compaction process is essential, yet crushed salt compaction involves several thermal-hydraulic-mechanical (THM) coupled processes and is influenced by internal, as well as external conditions.

Abstract:
The Colorado Geological Survey (CGS) estimates the total value of 2022 mineral and energy fuels production in Colorado to be $30.53 billion, a ~49% increase from the 2021 estimate of $20.51 billion mainly due to higher average prices for oil and natural gas. In 2022, the top commodities produced in terms of production value include: oil, natural gas, coal, molybdenum, gold, sand and gravel, cement, industrial gases (carbon dioxide), and crushed rock. Oil and natural gas production accounted for ~90% of Colorado’s total mineral and energy production value in 2022.

Abstract:
This report presents a case study for constructing aggregate subgrade improvement (ASI) layers using quarry by-product aggregates (QBA), a quarry mix of large primary crushed rocks (PCR) and sand-sized quarry fines. The construction took place at Larry Power Road in Bourbonnais Township in Kankakee County, Illinois, where the Illinois Department of Transportation placed two QBA mixes. The first mix (QBA_M1) consisted of 45% quarry by-products and 55% railroad ballast–sized 3×1 PCR. The second mix (QBA_M2) consisted of 31% and 69% quarry by-products and PCR, respectively. Two conventional ASI s
