Abstract:

At Ontario the main runway was rebuilt and 4-inch bituminous overlay put down at night while the runway was in daily use. Existing pavement was portland cement concrete with bituminous overlay on 7,000 feet of the 10,000 foot length. Non-destructive tests were made to locate weak spots for mud jacking or reconstruction. One-sixth of the runway was excavated 12 inches deep and backfilled with asphalt concrete. A maximum of 2,800 square yards were completed in one night. Paint and rubber were removed before placing overlay. A heater re-mix machine was used to heat and loosen the existing asphalt surface to fuse the new overlay to the underlying surface. Keeping the runway open avoided cancellation of 5,600 passenger flights.
