If the latter procedure is to be used the
distance between the runway and its parallel
taxiway must be carefully controlled Since the
mat width is 2 feet, a gap of almost 1 foot could
occur at each end of the interconnecting lateral
taxiway. The gap between the lateral taxi way
and the long taxiway and runway should not
exceed 2 inches.
Install W-degree connectors on the edge of the runway
at the point where the lateral taxiways will connect
with the runway. The 90-degree connectors may be
used at other points where two mat-laying patterns, at
90 degrees to each other, are to be joined.
NOTE: The 90-degree connectors can be used to
connect the end of the lateral taxiway with the long
The two procedures for installing 90-degree
connectors are as follows:
PROCEDURE NUMBER 1. Where the
adjoining pattern has not been laid, install a sufficient
number of 90-degree connectors along the 2-foot edge
of matting, such as the edge of the runway, equal to
the width of the taxi way or other section to be joined.
Lay a half-length mat into the first 90-degree
connector, so the end of the mat matches the end of the
connector. Engage the prongs of a full-length mat into
the prongs of the half-length mat previously laid and
push into engagement with the 90-degree connector.
Continue to lay mats in the above manner until the first
row is completed to the length of the 90-degree
connectors. Additional mats may then be laid in the
usual manner. (See fig. 11-25.)
PROCEDURE NUMBER 2. Where the
adjoining mat pattern has already been laid, adjust the
last few rows of matting (of the taxiway), so the space
