3. DW SHALL BE A MINIMUM OF 3' LENGTH, MEASURED FROM THE GRADE BREAK.

4. INSTALL WHOLE DW TILE UNITS ABOVE GRADE BREAK WITH 3' LONG UNITS. INSTALL

FACTORY EDGE OF DW UNITS ALONG GRADE BREAK BETWEEN GRADE BREAK AND BACK

OF CURB.

5. THE DW DOMES SHALL BE ORIENTED SUCH THAT THE ROWS ARE PARALLEL WITH THE

DIRECTION OF THE CURB RAMP. DW AT FLUSH TRANSITIONS SHALL BE ORIENTED IN

THE DIRECTION OF THE CROSSWALK. WHEN MULTIPLE TILES REGARDLESS OF SIZE ARE

USED, THEN THE DW DOMES SHALL BE ALIGNED BETWEEN THE TILES AND

THROUGHOUT THE ENTIRE DW INSTALLATION. DW TILES SHALL HAVE FACTORY EDGES

TOGETHER AT JOINTS.

6. THE EDGE OF THE DW TILE SHALL HAVE A BEVELED EDGE SLOPED AT 1 :2 MAXIMUM.

WHEN THE DW TILE EDGE OR A DOME IS CUT AND THE RESULTING EDGE/DOME IS

NOT FLUSH WITH THE SURFACE OF THE CURB RAMP, THE EDGE/DOME SHALL BE

BEVELED AT 1 :2 MAXIMUM SLOPE, IN ACCORDANCE WITH THE APPROVED DW

MANUFACTURER'S REQUIREMENTS. SEE DETAILS 4 AND 5.

7. RIGID CEMENTITIOUS DW PANELS MUST LIE IN A SINGLE NON-WARPED PLANE.

8. THE COLOR OF THE DW SHALL CONFORM TO FEDERAL STANDARD 595B TABLE IV,

GUTTER ELEVATIONS AND TO LIMIT CROSS-SLOPE ON RAMP TO BE 1.5% MAXIMUM.

ADJACENT PANEL EDGES SHALL BE FLUSH (NO VERTICAL OFFSET.)

10. WHEN THE CURB IS WIDER THAN 8 INCHES, THE CURB WITHIN THE CURB RAMP

SHALL BE 8 INCHES MAXIMUM. THE WIDE CURB OUTSIDE, WHERE OCCURS, SHALL

TRANSITION AT THE FLARED SIDE AS SHOWN ON DETAIL D.

11. SURFACE-APPLIED DW UNITS MAY BE USED ONLY WHERE PROVIDING CAST IN PLACE
