The method of producing a bowling lane having a surface characterized by a falling ball impact resistance of at least 60 inches, a coefficient of friction of about 0.16 and a Taber abrasion resistance of at least about 500 cycles comprising:
- laying a plurality of thermosetting resin impregnated glass core sheets between a plurality of thermosetting resin impregnated crepe paper core sheets in an alternating manner beginning with and ending with a crepe paper core sheet;
- consolidating said thermosetting resin impregnated core sheets, a resin impregnated decorative fibrous print sheet, and an overlying resin containing protective layer under heat and pressure to produce a unitary decorative plastic laminate sheet;
- and
- securing at least one such plastic laminate sheet to a substrate selected from the group consisting of natural wood, consolidated wood fibers, plywood, flakeboard, chipboard and hardboard to produce the desired bowling lane.
