The lightweight aggregate is an aggregate that weighs less than the usual rock aggregate and the quarry dust is a rock particle used in the concrete for the experimentation. The significant intention of the proposed technique is to frame a mathematical modeling with the aid of the optimization techniques. The mathematical modeling is done by minimizing the cost and time consumed in the case of ...

Stone powder sludge produced from a crushed aggregate factory was used to replace fly ash and granulated blast furnace slag at replacement ratios of 0%, 10%, 20%, and 30% by mass.
Substitution of thinner but much more costly black bases for untreated crushed stone bases brings these subgrade discontinuities that much closer to the surface where the loads are. There is a major advantage to the use of thicker cushions of quality controlled
Decomposed granite is usually obtained from weathered stone sources and then is mechanically crushed to form a course gravel-like consistency. Other than being used as an aggregate, decomposed granite is also used for laying paths, or as a mulch for gardens. It can be laid loosely, packed down or secured with epoxies to create an asphalt-like ...

· Plastic deformation behaviour of graded crushed stone (GCS) base affects the service life of flexible pavement. This paper presents a simple prediction model to characterize the plastic deformation behaviour of GCS base. A relative deformation model was proposed based on the deformation model developed by Pérez. The plastic deformation test was conducted using a rutting tester under different ...
Crushed stone, one of the most accessible natural resources, is a major basic raw material used by construction, agriculture, and other industries that utilize complex chemical and metallurgical processes. Despite the low value of its basic products, the crushed stone industry is a major contributor to and an indicator of the economic well-being of ...

· Unlike crushed stone, gravel is usually sold and used in its natural state. If it is crushed, gravel loses its unique smooth rounded texture and becomes crushed stone. It is important to note that some contractors refer to any stone in certain size ranges as "gravel," even if it is crushed stone.

The crushed glass was varied from 0 – 100% in steps of 25% by weight to replace the both the natural fine and coarse aggregate in the same concrete mix. Concrete mixes were prepared using a mix proportion of 1:2:4 (cement: fine aggregate: coarse aggregate) at water-cement ratio of 0.5 targeting a design strength of 20 MPa.
