315.01Description

This Section shall cover the work of constructing a drainage plane layer composed of an approved free-draining material. This layer normally is used to facilitate drainage from the pavement structure layer through the shoulders; however, it may be used at other locations when shown on the plans or directed.

315.02Materials

Materials for use shall meet the appropriate requirements of Division 800, Materials, with specific reference to Section 822.

315.03Construction Requirements

The drainage layer shall be constructed in reasonably close conformity to the cross sections and dimensions shown on the plans and in the sequence noted in Subarticle 301.04(c). The thickness shown on the plans will be loose measurement before covering with another layer. The drainage plane materials shall be spread by approved equipment capable of providing a single layer of uniform thickness, uncompacted, and continuous from the inner base layer edge through the shoulder line. The equipment must be capable of spreading this layer without damaging or disturbing the underlying and contiguous layers. Multiple passes may be permitted on wide shoulders. There will be no density requirement for this layer. Care shall be taken to ensure firm contact between drainage layer and the contiguous base layers. Any disturbance to or loss of drainage plane material while uncovered shall be corrected prior to placing the overlying layer.

315.04Method of Measurement

Measurement of Drainage Plane Material will be in accordance with Article 301.07.

315.05Basis of Payment

Drainage Plane Material, measured as noted above, will be paid for at the contract unit price bid for the item of work involved in accordance with Article 301.08.

315-A Drainage Plane Material, ___ inches {mm} Thick - per square yard {square meter} PLANT MIX BITUMINOUS BASE AND PATB 180

PLANT MIX BITUMINOUS BASE AND PATB

327.01Description

The work under this Section shall consist of constructing a Plant Mix Bituminous Base layer composed of an aggregate and bituminous material hot mixed in a central plant and hot laid on a prepared surface in accordance with these specifications and in close conformity with the lines, grades, typical section, mix, and average weight per square yard shown on the plans or directed by the Engineer. The work under this Section shall also include the construction of a Permeable Asphalt Treated Base

327.02Materials

The material requirements for Plant Mix Bituminous Base shall conform to the requirements given in Section 410 unless noted otherwise by the requirements given in this Section.

The type of required mix will be shown on the plans. The minimum allowable VMA shall be

13.0The job mix shall be designed by the Marshall Method or a 60 gyration gyratory compactor

design. The Marshall Method must produce a minimum of 1200 pounds {5.5 kN} stability at 50 blows or a minimum of 2,700 pounds {12 kN} stability at 60 gyrations, unless shown otherwise on the plans. The design air voids shall be 4.0%.

Fine aggregate shall meet the requirements given in Article 802.04. Coarse aggregate shall be gravel, processed reef shell, crushed slag, crushed stone, or a combination thereof meeting the requirements given in Section 801 unless noted otherwise by the requirements given in this Section. The coarse and fine aggregates shall be combined in a total blend that will produce an acceptable job mix within the gradation limits shown in the following table. The blend shall be made from at least two stockpiles of different gradations. At least 10% of the blend shall be taken from each of the stockpiles. The requirements for allowing the use of RAP and RAS are given in Article 410.02.
