terminals. Accordingly, concrete parking lots are constructed with a wide variety of construction equipment, ranging from hand tools and vibratory screeds to large highway paving equipment. Because of the relatively high stiffness of concrete pave-ments, loads are spread over larger areas of the subgrade compared with asphaltic pavements.
Longitudinal joints often look coarse, open-graded or segregated (Figure 4). This can happen for several reasons: The joint contains segregated material cause longitudinal joints occur at the edge of the paver screed and auger system their constituent material can come from material pushed out beyond the end of the auger and/or screed. Because it has been moved more and moved beyond the end ...
In addition, the stringline becomes an obstacle for equipment, concrete delivery trucks, and finishing crews. ... The carpet shall be a single piece long enough to reach across the width of the plastic concrete and having enough longitudinal length in contact with the concrete to produce the desired texture.

This is called tining. Tining can be done with a machine, or by hand with a tool. The first 2 pictures below show the end result with tining of the concrete pavement. The piece of equipment shown below is not paving at the moment, but it shows the...
· A construction joint is a joint between slabs that results when concrete is placed at different times. This type of joint can be further broken down into transverse and longitudinal construction joints. Longitudinal construction joints also allow slab warping without appreciable separation or cracking of the slabs.
