work- ing control on the jobsite.
2. Batching: The process of proportioning the cement, water, aggregates
and ad- ditives prior to mixing concrete.

cen- terline, caused by shrinkage or differential thermal stress of the asphalt

using a back-and-forth motion while moving across the surface.
6. Raveling: Wearing way of the pavement surface caused by dislodging of
aggre- gate particles and binder, usually a result of insufficient asphalt binder
in the mix or stripping of asphalt from particles of aggregate.
7. Batching: The most important process to prepare concrete.

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.

  1. Contraction 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 due to a decrease in temperature.

  3. Transverse Joint: Joints, placed in concrete pavements at right angles to the center line of the pavement.
  4. Bleeding: Generally, the dry materials used in making quality concrete are heavier than water. Thus, shortly after placement, they have a tendency to settle to the bottom and displace the mixing water to the surface.
