1On an asphalt street, interconnected cracking that forms a chicken-wire or alligator pattern most often indicates which pavement condition?
A.Fatigue failure of the asphalt layer over a weak or moisture-damaged support
B.Surface oxidation of the binder with no structural involvement
C.A single thermal contraction crack that has not branched
D.Excess tack coat bleeding through a new overlay
Explanation: Asphalt Institute MS-16 treats alligator (fatigue) cracking as a structural distress. Repeated wheel loads crack a thin or aged asphalt layer when the base or subgrade cannot carry the load, especially after water has weakened the support. Mild surface oxidation or a single thermal crack does not produce the interconnected pattern, and bleeding is an asphalt-rich surface condition, not a crack pattern.
2A bowl-shaped pothole in an asphalt lane most commonly starts from which combination of conditions?
A.A fog seal that was applied on a cool morning
B.Localized alligator cracking or surface breakup plus water and traffic
C.A chip seal with 50 percent chip embedment
D.A longitudinal cold joint that was rolled from the hot side only
Explanation: MS-16 describes potholes as bowl-shaped holes that usually begin as small patches of alligator cracking or surface disintegration. Water enters, the asphalt and base loosen, and traffic pops the fragments out. Preventive sealing and timely patching stop that sequence. Fog seals, normal chip embedment, and joint rolling technique do not by themselves start a pothole.
3Bleeding on an asphalt pavement is best described as which surface condition?
A.Loss of fine aggregate that leaves a coarse, open texture
B.A depression confined to the wheel path from mix instability
C.A film of excess asphalt that rises to the surface and can become slick
D.A map of rectangular cracks caused by binder shrinkage
Explanation: Bleeding (flushing) is free asphalt that has migrated to the surface, often from too much binder, a rich mix, or a heavy seal coat. The film reduces texture and can become slippery when hot or wet. Raveling is the opposite surface loss of aggregate; rutting is a wheel-path depression; block cracking is an aging-shrinkage pattern.
4Raveling of an asphalt surface is the progressive loss of which materials?
A.Only the liquid tack film under a new overlay
B.Dowel bars from a concrete joint that was overlaid with asphalt
C.Prime coat from an untreated subgrade that was never paved
D.Aggregate particles from the pavement surface, often starting with the fines
Explanation: MS-16 defines raveling as the wearing away of the pavement surface as aggregate particles dislodge. It often starts with the fines and leaves a coarse, open texture. Causes include aged, dry binder, poor compaction, and a dry or dirty mix. Surface treatments such as fog seals, slurry seals, or chip seals are used to lock remaining aggregate and seal the surface before the raveling becomes structural.
5A fog seal is applied to an existing asphalt surface primarily to do which of the following?
A.Place a light application of diluted asphalt emulsion to seal and enrich the surface
B.Add several inches of structural thickness for heavy trucks
C.Fill deep ruts and restore cross slope in one pass
D.Replace a failed base under alligator cracking
Explanation: A fog seal is a light spray of diluted asphalt emulsion. MS-16 and preservation practice use it to seal small voids, enrich an oxidized surface, and slow raveling. It is not a structural layer, it cannot fill deep ruts, and it will not repair a failed base. Those conditions need patching, milling, or reconstruction before any thin surface treatment.
6Per NMDOT 2019 Section 407, a tack coat is applied to an existing pavement primarily to provide which result?
A.A penetrating prime that binds an untreated aggregate base
B.A bond between the existing surface and the new asphalt course
C.A wearing surface that replaces the need for an overlay
D.A dust palliative on an unpaved detour
Explanation: NMDOT 2019 Section 407 describes tack coat as asphalt material applied to an existing HMA, WMA, or portland-cement concrete surface. The residual asphalt film bonds the old surface to the new course so the overlay does not shove or delaminate. Prime coat, not tack, is the penetrating treatment for untreated aggregate. Tack is not a wearing course and is not a dust palliative.
7A chip seal (asphalt seal coat) is constructed by applying which two materials in sequence?
A.Portland cement grout, then a sand blotter
B.A thick hot-mix overlay, then a fog seal only on the joints
C.A liquid asphalt binder, then a one-size cover aggregate that is rolled into the binder
D.A slurry mixture first, then a chip seal on top of the slurry
Explanation: MS-16 and standard seal-coat practice place a uniform film of asphalt binder (usually emulsion) and immediately cover it with clean, one-size chips. Rolling seats the chips into the binder so they are held as the wearing surface. A Cape seal reverses that order: chip first, then slurry. Cement grout and HMA overlays are different treatments.
8The throw-and-roll pothole method is best classified as which type of repair?
A.A full-depth structural reconstruction of the lane
B.A routed-and-sealed working-crack treatment
C.A microsurfacing rut-fill pass
D.An emergency or temporary fill in which mix is placed and rolled with truck tires
Explanation: MS-16 and SHRP pothole research treat throw-and-roll as an expedient method: place cold or hot mix into the hole and compact it with truck tires so the patch can be opened quickly. It is useful in poor weather but is not a structural rebuild. Durable repairs use cut-and-patch, spray injection, or a full-depth dig-out when the base has failed.
9Per NMDOT 2019 Section 408, a prime coat is applied for which primary purpose?
A.To provide and apply asphalt material, and blotter if required, to an existing untreated or prepared surface so the binder can penetrate and bind the surface
B.To bond a new HMA overlay to an existing asphalt or concrete pavement
C.To seal working concrete pavement joints with silicone
D.To mill the existing asphalt to a uniform profile
Explanation: NMDOT Section 408 describes prime coat as providing and applying asphalt material and blotter, if required, to an existing surface. Prime penetrates and binds untreated or newly prepared aggregate so it will accept pavement and shed water. Tack (Section 407) is the bond coat on existing pavement. Joint silicone and milling are separate operations.
10Rutting in an asphalt wheel path is best described as which distress?
A.A random map of rectangular shrinkage cracks
B.A longitudinal surface depression caused by consolidation or lateral movement of the mix or support
C.A polished, slick film of free asphalt with no change in cross slope
D.A single crack that crosses the lane at a right angle
Explanation: MS-16 classifies rutting as a channelized depression in the wheel path. It comes from densification of a poorly compacted mix, plastic flow of an unstable mix, or deformation of a weak base or subgrade. Standing water in ruts is a safety problem. Block cracking, bleeding, and a single transverse crack are different distresses.
