5.4.1.2.1. The Contractor shall form and install 4 inch thick concrete slab(s) over the subgrade region as illustrated in the applicable “backfill cross section” sketch. The 4 inch thick concrete slab(s) must match cross section, grades, finish and jointing of existing structures, to include but not limited to:

adjacent curb(s) and sidewalk(s).

5.4.1.2.1.1. The Contractor shall ensure the 4 inch thick

concrete slab is reinforced with welded wire or formed bar mats when either of the following conditions occur: (1) it was obvious that the originally removed concrete (see section 5.2.2.1) was reinforced or (2) the new slab is an “odd-shaped slab” as defined by section 14-1.3.1 of UFC 3-250- 01.

5.4.1.2.1.2. The installed slab must have a minimum

compressive strength of 3500 PSI (25MPa) when installed.

. 5.4.1.2.2. The Contractor must ensure the surface restoration includes positive drainage.

5.4.1.3. For areas of land where roadway(s), parking lot(s) or curb(s) and gutter(s) will be restored, install uniform lift (s) of sand, not exceeding 1 foot in compacted depth, to form a subgrade region. Each lift of sand shall be compacted to 95% of relative compaction as determined in accordance with ASTM D1557 before proceeding to the next lift. Hand compaction is not allowed. The subgrade region comprises the point

16 | P a g e where the initial backfill sand terminates, as illustrated in the applicable “backfill cross section” sketch, up to approximately 10 inches below ground level.

5.4.1.3.1. The Contractor shall form a 6 inch thick lift of MDOT 21AA material over the compacted sand subgrade region. This will form the base course. This base course shall be compacted to 95% of relative compaction as determined in accordance with ASTM D1557. Hand compaction is not allowed.

5.4.1.3.1.1. For roadway(s) and parking lot(s) only:

5.4.1.3.1.1.1 Apply tack coat uniformly to all

vertical surfaces abutting or projecting into new, hot-mix, at a rate of 0.05 to 0.15 gallon per square yard. Allow tack coat to cure undisturbed before applying hot mix asphalt.

5.4.1.3.1.1.2 The Contractor shall place a 2.5

inch thick leveling course (compacted depth) of MDOT 13A material over the compacted MDOT 21AA base course. This will form the leveling course. MDOT 13A material, forming this leveling course, shall be spread at a minimum temperature of 250 degrees F and compacted before the MDOT 13A cools to 185 degrees F. The leveling course shall be compacted in the following three rolling phases, in order: (1) breakdown rolling, (2) intermediate rolling and (3) finish rolling. Further details and requirements for each rolling phase can be found in general specification 32 12 16, section 3.7. Hand compaction is not allowed.

5.4.1.3.1.1.3. The Contractor shall place a 1.5

inch thick lift (compacted depth) of MDOT 13A material over the compacted MDOT 13A level course region. This will form the wearing course.
