greater impact on the unconfined compressive strength of the material[6] The combination of M 0 5 and M 10 20 can meet the strength requirements under medium and light traffic conditions Splitting strength The 7d and 28d age splitting strength tests were conducted on a mixture of coal gangue instead of crushed stones of
1 Introduction In the field of civil engineering the durability and stability of road bases are essential factors for ensuring the longevity and safety of road infrastructure [1 2] A crushed stone base is a widely used material for road construction due to its durability and cost effectiveness which is commonly used as a subbase material [3 4]
Produced with Crushed Stone Sand as Fine Aggregate Concrete is the largest man made material consumed by humankind with annual global consumption of 12 billion tons [1 2] By volume 70% of concrete comprises of 25 MPa target compressive strength of the control mixtures in each category The choice of the target compressive

Crusher dust is a fine material formed during the process of comminution of rock into crushed stone or crushed sand This dust is composed by particles which pass 75 μm BS sieve
Large particle size graded crushed stone mixtures LPS GCSMs can improve the shortcomings of conventional graded crushed stone such as low strength high deformation and a low modulus of resilience At present there is no systematic research on the gradation design and field evaluation of the LPS GCSMs In this study compaction and California
This increase correlated with a decrease in the unconfined compressive strength of RAP and RCCA mixes it is recommended to augment the thickness of the cement stabilized recycled crushed stone base layer in the road substrate the cement stabilized aggregates recycled base course with a 1 1 ratio between the surface material and the
Cement stabilized material showed higher strength values both early age and final compressive strength than conventional road base materials Those encouraging properties were confirmed by XRD
for base and subbase aggregate material is presented to identify possible similar material categories for which it is thought similar response and behavior will be exhibited HVS tests that were performed on pavements with unbound aggregate base layers were
