1000' of Skyline View Lane has been repaved and looks great!

On Thursday, 24 October, our road was repaved by the Granite Construction Company.  Mark Barton negotiated an exceptionally good price of $13,602 which was less than half what was expected to grade the existing road base, clean the existing pavement, add a binder, lay at least 3” of asphalt, and roll / compact it.  New resident, Marko Pala managed the project, worked out the technical details, and supervised the paving effort.  I leaned on shovel, watched the crew of 5 work, and took the pictures below.

The original plan was to lay 3” of asphalt, 10’ wide, from about 90’ of the gate (to cover the gravel added last year) to the bottom of the hill at Wheeler's, about 865’.  The plan was revised on paving day to merge the pavement with Guardsman Pass Road and extend it to the end of Wheeler’s driveway to provide a flatter transition to the hill, about 1000’.  In places the depth was increased on the south side of the road to ensure the grade tilted into the hill instead of away from it.   The two pullouts by Curtis’s were also paved to the width of 16’, which was the maximum capability of the paving machine.   A water bar was added to the middle of the hill to direct water to the ditch above the culvert.  The additional material may have increased cost by 10%.

The crew started at 7:30 AM and worked to about 4:30PM. 

The pictures show: the road base was cut/filled and graded to the level of the existing pavement, swept, and a binder was sprayed on the asphalt; the paving machine literally pushed the trucks up the hill (11 trucks were used); a roller compacted and smoothed the road surface; two guys controlled the thickness and measured the depth with gauges (the thickness was mostly greater the 3”); although not specified a technician used an instrument to measure compaction as part of Granite’s internal quality control; there was a lot of debate over the need for a water bar, it’s location, and shape.  It was decided to put it in the middle of the hill, and shape it like a triangle to make it easier to driver over (Granite’s suggestion).  The bottom 2 pictures show the pull-outs and the transition to GPR.  Granite did a nice job with the transition, filling holes at GPR and tilting the road away from the slope.

Remaining issues include, monitoring the ditches and water bar to ensure drainage is adequate, and modifying the gate to ensure there is adequate clearance for snow.  When the pavement was added, clearance at the gate bottom corner was decreased from about 8” to 4”.  We need to cut/re-weld the gate.  Perhaps Ross or Paul Nell could accomplish this. 


There are also concerns that snow/ice on the newly paved hill could melt and freeze at night presenting very hazardous morning conditions.  Drivers need to be very cautious  on the hill this winter.  It has also been suggested that a path be maintained on the side of the hill for walkers.
