Module 8: Pavement Analysis Flashcards
Constructed with asphaltic cement and aggregates, and usually consists of several layers.
Flexible Pavement
The lower layer or bottom-most component of a flexible pavement is called the
Subgrade
Constructed with Portland cement concrete and aggregates with flexible pavements.
Rigid Pavement
Joints placed in concrete pavements, which are usually placed transversely, at regular intervals, to provide adequate expansion space for the slab to expand when the pavement is subjected to an increase in temperature.
Expansion Joint
Joints placed in concrete pavements, which are usually placed transversely, at regular intervals, across the width of the pavement to release some of the tensile stresses that are induced due to a decrease in temperature.
Contraction Joint
Joints placed in concrete pavements, which are usually placed transversely across the pavement width to provide suitable transition between concrete placed at different times or on different days.
Construction Joint
A gap between the slabs that is typically filled with preformed joint material for the full depth of the slab.
Isolation Joint
The pavement thickness of a turnout shall no case be less than ____ for asphalt.
100 mm
The pavement thickness of a turnout shall no case be less than ____ for concrete.
230 mm
Vehicles parked near intersections can obstruct the flow of turning traffic. Thus, parking should be prohibited within the minimum distances from the boundaries of intersecting roads for parallel parking - ___ m on both approach and exit sides.
6 m
Vehicles parked near intersections can obstruct the flow of turning traffic. Thus, parking should be prohibited within the minimum distances from the boundaries of intersecting roads for angle parking - ___ m on both approach and exit sides.
12 m
The maximum design speed through roundabout should generally ___ in urban areas
40 kph
The maximum design speed through roundabout should generally ___ in rural areas
50 kph
An expressway with full control of access
freeway
An area within a roadway or between roadways from which vehicular traffic is intended to be excluded.
island
Part of the road that carries the traffic and has a set of layers or material placed over the natural ground (subgrade)
Pavement
The critical section of a contraction joint is located at
the edge and will crack approximately 45 degrees
The modulus of subgrade involves is dependent on
Pressure and Deflection
The basic formula for determination of pavement thickness was first suggested by
Goldbeck
Cement grouted pavement is classified as
Semi Rigid Pavement
Minimum thickness of the base of a flexible pavement is
100 mm
Newly constructed pavement with Ordinary Portland Cement attains its working strength after ____ days
28
An ideal pavement is constructed with
Portland Cement Concrete
The poorly graded sub-grade soil, thickness of sub-base, is
300 mm
