Portable screed guidance system

A method for guiding a portable screed, the method comprising:

• measuring a reference inclination of the portable screed;
• measuring the vertical position of the portable screed relative to a reference plane;
• controlling the inclination of the portable screed during screeding to maintain the inclination of the portable screed within a desired tolerance of the reference inclination;
• and
• controlling the elevation of the portable screed during screeding to maintain the vertical position of the portable screed within a desired tolerance of the reference plane.

A portable screed comprising:

• a blade;
• one or more handles operatively associated with the blade;
• one or more inclination sensors adapted to measure and indicate the inclination of the portable screed during screeding;
• and
• one or more level sensors adapted to measure and indicate the vertical position of the screed relative to a reference signal during screeding.

A two-man portable screed comprising:

• a blade;
• first and second handles operatively associated with the blade;
• first and second inclination sensors adapted to measure and display first and second inclinations, respectively, of the portable screed during screeding;
• and
• first and second level sensors adapted to measure and display first and second vertical positions, respectively, relative to a reference signal during screeding.
