I RECENTLY RECEIVED A PAVEMENT DESIGN COMMENT FROM THE NEW JERSEY DEPARTMENT OF TRANSPORTATION WITH REGARDS TO THE DESIGN LIFE OF PAVEMENT STRUCTURES.
QUOTE: IT IS RECOMMENDED THE NEW PAVEMENT FOR 30 TO 50 YEAR RANGE DESIGN LIFE TO ACCOMODATE THE 75 YEAR LIFE OF THE BRIDGE STRUCTURE. THE DESIGNER SHOULD CHOOSE THE DESIGN WHICH PROVIDES THE MAXIMUM DESIGN LIFE WITHIN THE BUDGET CONSTRAINTS.
MY QUESTION IS : I HAVE BEEN LOOKING FOR THE 75 YEAR VALUE
THAT GOVERN THE LIFE CYCLE ANALYSIS PERIOD. IS THERE ANY REFERENECE OUT THERE THAT STATES THE BRIDGE STRUCTURE DESIGN LIFE VERSUS THE ATTACHED PAVEMENT DESIGN LIFE.
CAN ANYONE POINT ME IN THE DIRECTION TO A REFERENCE THAT STATES SOMETHING SIMILAR??????
