A. 
After completion of the rough grade in accordance with § 152-12 and prior to laying of the foundation course, the subgrade shall be shaped to line and grade and thoroughly compacted with an approved self-propelled roller weighing not less than 10 tons. All hollows and depressions which develop during rolling shall be filled with acceptable granular material and again rolled. This process shall continue until no hollows or depressions develop. The subgrade shall not be muddy or otherwise unsatisfactory when the foundation course is laid upon it.
B. 
Any soft or unstable portions of the subgrade which develop under the roller shall be completely excavated and removed from the right-of-way and shall be replaced with acceptable granular material and the area regraded and compacted as above.
A. 
Before fine grading of subbase material or construction of curbs and sidewalks is started, all storm and sanitary sewers and all utilities, including house connections and hydrants, shall have been installed, and all fill and backfill shall have been thoroughly compacted to the satisfaction of the Town Superintendent of Highways.
B. 
Fine grade shall conform to the prescribed width of pavement and shall conform to the typical cross section of the road pavement and to the approved line and grade.
A. 
After the fine grade and all curbs have been constructed to the satisfaction of the Town Superintendent of Highways, the developer shall furnish and place a foundation course of approved crusher run stone or crusher run gravel to the depth as called for in these specifications. All materials acceptable for these courses shall be hard, durable and sound and shall be well-graded from coarse to fine. One hundred percent by weight of the particles shall be of such a size as will pass through a two-inch square hole, 25% to 60% by weight shall be 1/4 inch, and 5% to 40% by weight shall pass through the No. 40 mesh sieve and 0% to 10% by weight shall pass through the No. 200 mesh sieve.
B. 
The materials shall be placed on the finished subgrade in six-inch layers and shall be thoroughly compacted by rolling with a self propelled ten-ton roller. Water shall be added to the material in such amounts as the Town Highway Superintendent may consider necessary for proper compaction. After compaction, the surface shall be true to grade and cross section, and any depressions shall be eliminated by the use of additional granular material thoroughly compacted so that it will not weave under the roller, and the total depth after compaction shall not be less than 12 inches.
