SIDEWALK: That portion of the roadway primarily constructed for the use of pedestrians. ERRATIC: Values which seem to vary excessively from the average. Pre-stressed concrete is economical for spans which are large or where the beam depth must be reduced to a minimum. When the water evaporates, the asphalt sets. IMPERVIOUS: Resistant to movement of water; a description of relatively waterproof soils such as clays through which water percolates at about one millionth of the speed with which it passes through gravel. (2) Fluid or semi-fluid cement slurry or slurry made with other materials for pouring into the joints of brickwork or masonry or for injection into the ground or pre-stressing ducts. Aprons are almost always extension of culverts. CONTRACT: The written agreement between the State (Client) and the contractor setting forth the obligation of the parties there under, including, but not limited to, the performance of the work, the furnishing of labor, equipments and materials and the basis of payment. Its heat rate and total heat generation are lower than for normal Portland cement. LUMINAIRE: Complete lighting device for the highway. Definition of Terms.” (a) The practice of civil engineering within the meaning and intent of this Act shall embrace services in the form of consultation, design, preparation of plans, specifications, estimates, erection, installation and Back-walls and parapets of abutments and wing walls of bridges shall be considered as parts of the substructure. Two main methods for pre-stressing are: post-tensioning and pre-tensioning. With respect to the Contractor, it is the obligation of complying with the Contract requirements during the construction period. ALIGNMENT: (1) The fixing of points on the ground in the correct lines for setting out a road, railway, wall, transmission line, canal, etc. OVERBURDEN: Material of inferior quality which overlies material of desired quality and which must be removed to obtain the desired material quality. ARTERIAL HIGHWAY: A general term denoting a highway primarily for through traffic usually on a continuous route. (2) A ground plan showing a route, as opposed to a profile or section, which shows levels and elevations. GABIONS: Compartmented rectangular containers made of galvanized hexagonal steel wire mesh and filled with stone. Vault : An arched masonry structure (with series of arches). The top layer is sometime called a “wearing course”. DILUTION: Reducing a concentration of soluble material by adding pure water. Where possible, they should be placed at points where cracking (or buckling) might start.

Two types are known, the first beneficial, the second harmful to concrete strength, but they may co-exist. SILT: Granular material passing the No. It is suitable for use when the structure must be put into early use or when long-term protection against cold temperatures is not feasible. FILLET WELD: A weld of roughly triangular cross-section between two pieces at right angles. UNIFORM FLOW: Flow which has a constant depth, volume and shape along its course. This is an indication of the clay content on a soil or aggregate. CLAY: Very fine-grained soil of colloid size (Finer than 0.002 mm), consisting mainly of hydrated silicate of aluminium. BLINDING: Mat or mattress or sealing coat. Veneered Wall: In a wall in which the facing material is merely attached to and nor properly bonded into the backing. Bevel: Any inclination of two surfaces other than 90 deg. PORTLAND CEMENT: A product obtained by pulverizing clinker consisting mainly of hydraulic calcium silicates. MILLING: (1) Removing a specified thickness of an existing pavement surface by grinding with a milling machine. EMBANKMENT: A ridge of earth or rock placed, shaped and compacted to carry a road, railway, canal, etc., or to contain water. Used on soils to determine coating requirements for new pipe and used to determine the extent of corrosion of existing metal pipes. QUARRY: An open pit from which building stone, sand, gravel, mineral, or fill, can be obtained. The requirement for a slab, which is two-dimensional, being therefore about 0.2% altogether. CONSISTENCY OF CONCRETE: Ease of flow or workability of concrete, measured by slump test or Kelly ball test. 200 sieve. A horizontal (usually ornamental) course projecting along the face of a building (usually introduced at every floor level or under Windows or below parapets) for imparting architectural appearance to the structure and also keeping off the rain water. Mat finish : A term applied to surface finishing (generally painting) which is free from gloss or polish (not shining). RIGHT-OF-WAY: A general term denoting land, property of interest therein, usually in a strip, acquired for or devoted to transportation purposes. CONSOLIDATION: The gradual, slow compression of a cohesive soil due to weight acting on it, which occurs as water, or water and air are driven out of the voids in the soil. Slag is also used in making expanding cement and super-sulphated cement. SCARIFIER, RIPPER OR ROOTER: An implement which may be self-propelled or towed behind a tractor, with downward projecting tines for breaking a road surface for approximately two feet deep or less. HEDGE: A row of closely planted shrubs forming a fence. POTENTIAL ENERGY: Energy due to position such as the elevation head of water or the elastic energy of a spring or structure caused by its deformation. BORROW: Suitable material excavated from sources outside the roadway prism (e.g., Borrow Pit), to provide fill elsewhere, primarily for embankment. Their location is important. The first occurs during compaction, water can flow out of concrete, lie on its surface, and thus encourage good curing for the first few hours during hot weather.
