of inert material that is hard, durable stone as specified previously,
and coarse sand, clean, free of organic matter, free from loam and
clay, surface coatings, and detrimental materials as determined by
the Planning Board and consisting of no stones over three (3) inches
in diameter. The gravel shall be spread in two (2) layers, each thoroughly
watered, and rolled true to line and grade to conform to the typical

one-inch (after compaction) leveling course, if required, as determined
by the Planning Board, and a one-inch (after compaction) finish course,
in accordance with Massachusetts Department of Public Works Standard
Specification B-18, after the treated roadway has been subjected to
traffic for a time specified by the Director of Public Works. The
binder course shall be in place a minimum of one (1) year, including
one (1) full winter season. The leveling course shall be in place
a maximum of one (1) week before final coat. Final coat will be allowed
according Mass. Highway "Standard Specifications for Highway and Bridges"
commonly referred to as the "BLUEBOOK," except as noted in these subdivision

[Amended 10-18-2000 ATM, Art. 14]
(1)
Except as determined and directed by the Planning
Board's Inspection Engineer assigned to the development, with the
approval of the Planning Director. Determination and direction shall
be dependent upon the necessity and emergency of attendant circumstances,
weather conditions, and location of project;
(2)
The dispatching of trucks from the mixing plant shall
be so arranged that all material which is to be delivered for surfacing
any day may be placed and shall receive final compaction before nightfall
of the same day, unless artificial light, satisfactory to the Inspection
Engineer is provided;
(3)
When the air temperature falls below 50° F., extra
precautions shall be taken in drying aggregates, controlling the temperature
of the materials, placing and compacting mixtures;
(4)
The temperature of any mixture, with a tolerance of
+/- 15° F., when delivered at the project site, will be governed
by the temperature of the base upon which the mixture is placed, controlled
by the Mat Thickness Temperature Table listed in Section 460.61 of
the Massachusetts Highway's "Standard Specifications for Highway and
Bridges";
(5)
The mixture shall be placed upon approved surfaces that are clean from foreign matter and dry, and when weather conditions are suitable. The Inspection Engineer may, however, at the entire responsibility of the developer, permit work to continue when overtaken by sudden rain, limited to the material which may be in transit from the mixing plant at the time, and then only when the temperature of the mixture is within the temperature limits in Subsection E(4) above, and existing surface is not excessively wet. The developer will be cognizant that this pavement work may not be credited under the security arrangements.
