19 EXTENDING PAVEMENT LIFE BY SPECIAL MAINTENANCE ACTIONS Lino Lakes has typically engaged in chip seals, cold in place recycles or reconstructs to extend the life of a roadway. These maintenance actions are anticipated to last several years and be cost effective. Chip sealing includes pre -sweeping and filling of al l cracks in the pavement. A layer of emulsified (liquid) asphalt is applied uniformly across the pavement surface. This is followed by a uniform cover of traprock chips. Chip sealing creates a surface seal to the existing pavement, which provides additi onal support for traffic loads, and protection from weather conditions. Cold in place recycling involves reclaiming the asphalt surface in place, compacting the recycled material and placement of a bituminous wearing course over the entire surface. This t ype of action provides a structural improvement to the roadway. Reconstruction includes the complete removal of the existing pavement and aggregate base course. The roadway will be replaced with the City street standard of a minimum 32 -foot width (back of curb to back of curb) bituminous road with concrete curb and gutter.

This report includes updating the data to the previous report done in 2004. The existing model was used to stay consistent with what has been done in the City in the past. In order to maximize the life cycle of the pavement at minimum maintenance cost, the proper maintenance actions need to be undertaken at the optim um time. An updated proposed schedule for these special maintenance activities, different than what was proposed in th e 2004 report is provided below in Table 1 . This updated schedule includes performing maintenance activities based on the age of the pavement, not simply on the OCI value.
