Sudden rains cause trouble in our paving operations. The fresh concrete behind the paver is spread out over quite a distance and we have a hard time reaching it all in time to give protection. Is there any way to make this easier?
Some contractors have a mechanical device from which polyethylene sheeting can be quickly unrolled; the device is located on the front end of the machine they use for spraying liquid membrane curing compound on freshly placed concrete. It is claimed that 1,000 lineal feet of pavement can be protected in this way within a few minutes.
