Attached are two copies of a report entitled "Lateral Load Distribution and<br />

Use of PCC Extended Pavement Slabs for Reduced Fatigue." The report was<br />

written by Mr. Mark Sehr, Highway Engineer Trainee, and the final editing was<br />

. done by ERES Consultants.<br />

The paper sumnarites data and findings from several studies on Lateral Load<br />

Distribution and Load Stress at Pavement Edge. It includes discussion of the<br />

advantages of extended (or widened) lanes for PCC <strong>pavement</strong>s and their effect<br />

on stress, strain, deflection, and PCC <strong>pavement</strong> deterioration.<br />

We believe Mr. Sehr has prepared an excellent report and that it should be<br />

distributed to the division offices and shared with the States. We don't,<br />

however, have a sufficient number of copies to accomplish the desired<br />

distribution. Feel free to,make copies or contact Mr. Donald Petersen at<br />

FE 366-2226 to arrange for the printing of additional copies, or if you have<br />

any questions concerning the report.<br />
