HERRIMAN CITYPAVEMENT MAINTENANCE PROGRAM Herriman City
Engineering Department
Introduction
Herriman City has experienced tremendous growth over the last several years
Many new subdivisions and associated roads have been constructed in the City
Deterioration
The rapid growth and construction activity has exposed our roads to traffic and heavy loads, which in some cases accelerated the deterioration of our roads
InventoryCurrently Herriman City has as
an inventory of 17,821,898 SF of asphalt road.
A well implemented preventive Road Maintenance plan is needed to take care of our roads and keep them operative and functional.
Preventive Maintenance
Preventive Maintenance not reactive maintenance
Deterioration = Life
Very Cost Effective Applicable for all pavements Right treatment, right pavement, right time Importance of life-cycle cost analysis
Preventive Maintenance
Pavement Life Curve
Starting Early Saves Money
“Every $1 spent in keeping a good road good precludes spending $6-$14 to rebuild one that has deteriorated.”
