Near-freezing temperatures are delaying pavement scheduled
for Jones-Maltsberger and for the western segment of the parkway, causing
project managers to find creative solutions to getting work done while waiting
on critical asphalt work.
TxDOT specifications require temperatures above 60 degrees
to lay asphalt. That temperature is not a problem for most of the year in this
part of Texas, but with the winter norther blowing through the area work across
the area is slowing.
Millers will be moving across the western portion of the
parkway this week, preparing the road for a final surface of asphalt. Paving
crews are tentatively scheduled to move in next week – Monday – if temperatures
have risen enough to get the work done.
On Jones-Maltsberger, the subgrade and base is built;
project managers are waiting for paving crews to come through to finish the
future southbound lanes of the city street so traffic can be moved to its next
phase. That shift – the final shift before traffic is put into its final
configuration – will divide northbound and southbound traffic, allowing for a
work area between the two directions of traffic.
Temperatures are also impacting the ability to pour
concrete, which requires temperatures at least in the 40s before concrete can be
poured. Most of the work being held up by inability to pour concrete is on the
east side of the project, including the concrete paving blocks near the brush
site operated by the city of San Antonio on Old Bitters Road.
