or temperature prevents good workmanship. Temperature restrictions and protection
requirements may be modified by the Engineer under unusual conditions.
2. Cold Weather:
a. Paving: Do not place aggregates containing frozen lumps, and do not
place concrete on a frozen subgrade or subbase. Take all necessary actions to
prevent the pavement from freezing.
l) Concrete mixing and placement may be started, if weather conditions
are favorable, when the air temperature is at least 34°F and rising. At the time
of placement, concrete must have a temperature in conformance with ACI 306R-
88, Table 3.1.
2) Stop mixing and placing when the air temperature is 38°F or less and
falling or if the temperature stops rising and does not reach 38'F.
b. Protection: Prior to applying protection, cure all concrete pavement and
curb/gutters, including exposed edges of the pavement and curb. In addition,
protect concrete less than 36 hours old as follows:
Night Temperature Forecast Type of Protection]
35°F to 32°F One layer of burlap for concrete.
31°F to 25°F Two layers of burlap or one layer of plastic on
one layer of burlap.
Below 25°F Four layers of burlap between layers of 4 mil
plastic or equivalent commercial insulating
material approved by the Engineer.
Keep protection in place until one of the following conditions is met:
a. The pavement is 5 calendar day old
b. 4,000 psi strength is attained.
c. Forecasted low temperatures exceed 35°F for the next 48 hours.
d. Forecasted high temperatures exceed 55°F for the next 24 hours
and subgrade temperatures are above 40°F.
1) Shut down paving operations in time to comply with protection
requirements outlined above. During cold weather, allow more time for
104
finishing and protection. Perform all finishing and covering operations prior to
darkness.
2) Equivalent commercial insulating material approved by the Engineer may be
used. This material must be waterproof and have a minimum R value of 1.0. If
initial set has not yet occurred, place a layer of burlap on top of concrete prior
to placing insulating blankets.
3) Use a method of protection and materials that will maintain the concrete
temperature above 40°F.
C. Payment: Payment will be made in accordance with Section 01270, Measurement
and Payment. No additional payment will be made for curing and required cold weather
protection but shall be incidental to the bid unit price for concrete pavement protection but
shall be incidental to the bid unit price for concrete pavement.
