Every spring, the Engineering Department completes the annual asphalt street pavement condition survey. From this survey, the annual Street Resurfacing Priority List is developed based on the observed condition of the streets. The list is used as a guide for the preparation of the annual street resurfacing contract. A brief explanation of the priority system is as follows:

• Priority 1 - Street requires resurfacing as soon as possible
• Priority 2 - Street requires resurfacing in the next one to two years
• Priority 3 - Street should be surveyed every year, maintenance procedures may extend time until resurfacing required, resurfacing necessary in approximately two-four years
• Priority 4 - Street in fair condition, survey condition again in two years
• Priority 5 - Street in good condition, survey condition again in three years

The “Type” column of the list indicates which method of resurfacing will be done. “R” indicates the method by which the existing surface is heater scarified and rejuvenated and a thin (1”– 11/4”) bituminous wearing surface is added. “M/O” denotes a method by which an optimum thickness (11/2” – 2½”) of the existing surface is milled off and a new surface of approximately equal thickness is added. “O” represents a straight overlay method where the existing surface is leveled with thin layer of bituminous material and then a 11/2” – 2” bituminous overlay is laid.
