The size of the particles determines whether it is a coarse aggregate (e.g. gravel) or a fine aggregate (e.g. ______)

The resulting concrete can be used in its natural state or ______, according to its use and application

Tests are required to establish elastic and delayed settlement of the rock under applied ______

Designing of cut slopes for highways, railways, canals, pipelines and penstocks may involve testing and analysis of the system of ______.

Considerable cost savings are possible if the orientation of the right-of-way can be adjusted based on the rock mechanics studies, but this is not always ______.

The decision to place portions of transportation routes underground is partly determined by judgments about the rock conditions and relative costs of open cuts and ______.

Fields of Application of Rock Mechanics Project: Transportation routes involve the design of cut slopes for highways, railways, canals, pipelines, and ______.

Adjustments in the right-of-way orientation based on rock mechanics studies can lead to significant ______ savings.

Cut slope is also known as "Back slope" or "cut bank". It is an artificial face or slope cut into soil or rock along the inside edge of the road. This is commonly found on the _____ edge of the road.

Ditch, also known as "Side drain", is a channel or shallow canal along the road intended to collect water from the road and adjacent land for transport to a suitable point of disposal. It is commonly along the _____ edge of the road.

Fill slope, also known as "Embankment slope", is the inclined slope extending from the outside edge of the road shoulder to the toe (bottom) of the fill. This is the surface formed when excavated material is placed on a prepared ground surface to construct the road subgrade and roadbed template. This slope is located on the _____ edge of the road.

Through cut is a road cut through a hill slope or, more commonly, a ridge, in which there is a cut slope on both sides of the road. It creates a road that goes _____ a hill slope or ridge.

A ditch is a channel or shallow canal along the road intended to collect water from the road and adjacent land for transport to a suitable point of disposal. It can be along the _____ edge or along both sides of the road.

The fill slope is the inclined slope extending from the outside edge of the road shoulder to the toe (bottom) of the fill. This slope is formed when excavated material is placed on a prepared ground surface to construct the road subgrade and roadbed template. Fill slopes are found on the _____ edge of the road.

Rock mechanics deals with the properties of rock and special methodology required for design of rock-related components of engineering schemes. 2 Fields of Application of Rock Mechanics Tests/Activities that usually require rock mechanics input: Evaluation of geological hazards in quantitative terms, selection and preparation of rock materials, evaluation of cuttability or drillability of rock and design of cutting and drilling tools, layout and selection of types of structures, analysis of rock deformations, analysis of rock stability, supervision and control of blast procedures, design of support systems, Hydraulic ______
