`
`SAND: granular material passing the No.4 (4.75 mm) sieve and predominantly retained on the No. 200
`(0.075 mm) sieve, either naturally occurring or the product of processing, i.e., manufactured sand.
`SAND ASPHALT: a mixture of sand and asphalt binder, cutback or asphalt emulsion. It may be pre(cid:173)
`pared with or without special control of aggregate grading and may or may not contain mineral
`filler. Either mixed-in-place or plant mix construction may be employed. Sand asphalt is used in
`construction ofboth base and surface courses.
`SATURATES: a mixture of paraffinic and naphthenic hydrocarbons that on percolation in a paraf(cid:173)
`finic solvent are not absorbed on the absorbing medium. Other compounds such as naphthenic
`and polar aromatics are absorbed thus permitting the separation of the saturate fraction.
`SCARIFICATION: ripping (usually with grader teeth), reshaping, and recompacting a pavement
`surface and/or base and/or subbase layer.
`SCARIFICATION: removal of the top 1 to 2 inches (25 to 50 mm) of an asphalt pavement using a
`bank of tines/teeth or a rotating milling drum.
`SCREEN: in laboratory work an apparatus, in which the apertures are circular, for separating sizes
`of material.
`SECONDARY CRACK: a crack extending parallel to a primary crack.
`SEGREGATION: a deficiency in pavement components where the coarse particles are separated
`from the fine matrix.
`SERVICEABILITY: the ability, at time of observation, of a pavement to serve traffic that uses the
`facility.
`SHALLOW PATCHING: a maintenance treatment where the surface layers( s) of asphalt concrete is
`removed and replaced with well compacted asphalt concrete.
`SHOULDER: the non-travel portion of a road on each side of the pavement.
`SHOVING: permanent, longitudinal displacement of a localized area of the pavement surface
`caused by the traffic-induced shear forces.
`SIEVE: in a laboratory work an apparatus, in which the apparatus are square, for separating sizes
`of material.
`SKID NUMBER (SN): a standard test measure of the friction between a tire and a wetted road surface.
`SLAB: a load bearing layer of Portland cement concrete, with or without reinforcement, sized to
`control and minimize shrinkage cracking.
`SLURRY SEAL: a surface treatment of asphalt emulsion, sand, Portland cement, and water, placed
`as a slurry. Single or multiple applications may be used.
`SOIL: sediments or other unconsolidated accumulations of solid particles which are produced by the
`physical and chemical disintegration of rock and which may or may not contain organic matter.
`SPRAY INJECTION: repair technique for potholes in asphalt-surfaced pavements and spalls in Pee(cid:173)
`surfaced pavements that uses a spray-injection device. Spray-injection devices are capable of
`spraying heated asphalt emulsion, virgin aggregate or both into a distress location.
