ABSTRACT:
The present invention relates to a heated mat assembly for preventing snow and ice accumulation on a driveway. The device comprises a substantially rectangular, rubber pad having planar upper and lower surfaces and four peripheral edges. Disposed between the upper and lower surfaces are a plurality of inner layers preferably constructed with a fiberglass cloth. Embedded within the inner layers are a plurality of heating elements in communication with a thermostat and power cord for selectively activating the heating elements upon the thermostat detecting a temperature below a predetermined value. Along the entire length of opposing edges of the pad are a pair of troughs for draining water from the upper surface directly onto a street. Adjacent each trough are a pair of straps having a grommet at a distal end thereof for receiving a fastener means to anchor the pad to the soil immediately adjacent the driveway. The device may remain connected during colder months and will only be activated when ambient temperatures fall below a predetermined value. When warmer months arrive, the device may be easily rolled up for storage.
