(1) Sampling of Test Materials. The test materials were sourced from the aggregate yard on-site, ensuring a gravel particle size range of 5 mm to 31.5 mm. Using a gravel vibrating screen combined with standard testing sieves, 100 kg of gravel in the 9.5 mm to 16 mm size range and 100 kg in the 16 mm to 26.5 mm size range were screened.

California Bearing Ratio (CBR): The CBR test is a simple strength test that compares the bearing capacity of a material with that of a well-graded crushed stone (thus, a high-quality ... the American Society for Testing and Materials (ASTM ...
The CFG (cement-fly ash-gravel) pile composite foundation system has been widely used in buildings, highways, railways, and bridge transition sections owing to its proven engineering ...
Gravel piles not only enhance the bearing capacity of the foundation but also expedite soil drainage and consolidation. Additionally, they offer benefits of simplicity in structure and cost-effectiveness [1], [2]. The performance strength of gravel piles depends on the confining pressure exerted by the surrounding soil on the pile body.
R-Value (California Test 301, ASTM D 2844, AASHTO T-190): The R-value test method is used to measure the potential strength of subgrade, subbase, and base course materials used for transportation pavements. 2,7; Table 7 provides a number of testing procedures that can be used to determine aggregate suitability for a variety of uses.
These codes specifies testing procedure and methods for concrete, masonry, aggregates, steel, soil and other building materials. Codes and standards are living documents, continually …
This paper presents a special case study on the performance of geosynthetics-reinforced and pile-supported embankments (GRPS) over silty clay of medium compressibility. A full-scale high-speed railway embankment with four instrumented subsections over medium silty clay was constructed in three stages. Three of the sections were reinforced by geosynthetics …

Additional studies shall be made as necessary to evaluate slope stability, soil strength, position and adequacy of load-bearing soils, the effect of moisture ...
It covers such topics as: 1) Administrative requirements; 2) pile shaft strength requirements; 3) soil-pile interface strength requirements and capacity; 4) design loads; 5) design stresses; 6) …
The behavior for a laterally loaded pile is sophisticated when it is located in the sloping ground. The gravel soil is a typical strata of western Sichuan province of China, but the response of piles in the gravel soil ground has been very little studied. The field tests in this study were conducted to investigate the single pile response for varying gradients of gravel soil …
Grouted gravel pile is a new technique of piles for reinforcing soft soils. It has been successfully used in construction of projects of expressway and high-speed railway.
Gravel is a common geotechnical material in civil engineering. To investigate the lateral bearing behavior of monopile in gravel materials and deeply understand the microscopic mechanisms, parametric three-dimensional discrete element analyses are performed to study the lateral interaction between the single pile and gravel. First, using the experimental data of two …
