Cover Page, Comprehensive Truck Size and Weight (TS&W) Study; Phase 1-Synthesis; Pavements and Truck Size and Weight Regulations; Working Paper 3. February 1995. Prepared for Federal Highway Administration, U.S. Department of Transportation; by Battelle Team, 505 King Avenue, Columbus, Ohio 43201-2639.

This online resource is provided as a teaching tool, that persons may be better informed, regarding the durability of flexible vs. rigid pavement surfacings.

This study is titled:

Comprehensive Truck Size and Weight (TS&W) Study | Phase 1-Synthesis | Pavements and Truck Size and Weight Regulations | Working Paper 3 | February 1995 | Prepared for the U.S. D.O.T./FHWA (United States Department of Transportation/Federal Highway Administration | Prepared by Battelle Team, 505 King Avenue, Columbus, Ohio 43201-2693.

The critical, essential reason for this, and preceding, studies was:

To determine the most long-lasting + durable type of pavement surfacing, for US Highways and for the newly commissioned Interstate Highway System.

The principal difference between the flexible and rigid pavement ESAL values is that tandem axles were found to have a greater effect on rigid pavements (Exhibit 1). "For example, a 34,000-pound tandem axle is about 1.1 ESALs on flexible pavement and about 2.0 ESALs on rigid pavements."
