Supplemental Description Deflection Criteria I Minimal Deflection < 6 in ch II Low Deflection < 24 in ch III Medium Deflection < 60 in ch IV High Deflection < 96 in ch
Deflection values are based on NCHRP testing for corresponding level and is permanent deflection measured at the bottom of the barrier.
543 SECTION 637 WATER
637.1 -DESCRIPTION : This work shall consist of furnishing, and applying or incorporating, as the case may be, water required for compacting embankments, for stabilizing soils or other materials, as a dust palliative, or for any other specially designated purpose, in accordance with these Specifications and in accordance with the requirements of the Plans or as directed by the Engineer.
637.2 -MATERIALS : Water shall conform to the pertinent requirements set forth in these Specifications for its specific uses or, in the absence of such specific requirements for the designated use, the water shall be suitable for the purpose intended and shall be free of substances which would be deleterious to the work involved.
637.3 -CONSTRUCTION METHODS : The equipment to be used with the water operation involved will be approved by the Engineer as adequate and suitable for the purpose intended. Water shall be incorporated in the manner, in the amounts, at the times, and for the purposes prescribed in these Specifications or as directed by the Engineer.
637.4 -METHOD OF MEASUREMENT : When the Contract includes a separate item for "Water", it will be measured by the gallon, expressed in thousand -gallon units, and the quantity to be measured for payment will be the amount of water furnished and used for the purposes specifically designated as being included under the pay item. Measurements will be by means of tanks or tank trucks of predetermined capacity or by means of satisfactory and approved meters furnished by the Contractor. Water used by the Contract or for purposes other than those specifically included in the item shall not be paid for separately. When the excavation is less than 10,000 cubic yards and separate payment for water is not included in the plans the water shall be incidental to the work and shall not be paid for separately.
637.5 -BASIS OF PAYMENT : The quantity, determined as provided above, will be paid for at the contract unit price bid for the item below which price and payment will be full compens ation for furnishing all the material and doing all the work prescribed in a workmanlike and acceptable manner, including all labor, tools, equipment, supplies, and incidentals necessary to complete the work.

544 SECTION 638 PROJECT MARKERS, RIGHT -OF-WAY MARKERS, SURVEY MARKERS , AND OUTLET MARKERS
638.1 -DESCRIPTION : This work shall consist of furnishing, and placing or installing at the points designated on the Plans, in the Contractor’s Proposal or by the Engineer, metal (signpost) project markers, right - of-way markers, concrete survey markers, and outlet markers in accordance with these Specifications and in reasonably close conformity to the lines, grades, dimensions, locations, and sections shown on the Plans, in the Contractor’s Proposal or established by the Engineer.
638.2 -MATERIALS : Right -of-way Markers shall consist of # 6 (# 20) deformed reinforcing steel bars meeting the requirements of AASHTO M 31 and caps provided by the Division. Materials for project markers shall conform to the requirements specified on the Plans. Survey mar kers shall be constructed of concrete conforming to subsections 715.12 or 715.19. Survey Markers constructed without reinforcement shall contain sufficient steel near the top to provide magnetic detection. The materials for Outlet Marker Signs, such as f or the sign panels, their supports, and for the legend and background, are to be of a type and method of fabrication that will be consistent with the conditions and estimated period of use. Signs shall have black letters for the legend on a white backgrou nd. Reflective sheeting will be permitted, but not required.
CONSTRUCTION METHODS
638.3 -RIGHT -OF-WAY MARKERS : 638.3.1 -Right -Of-Way Marker Inst allation: Markers shall be set plumb and to a minimum depth of thirty -six ( 36) inches and shall be flush to the ground. When rock is encountered in areas of proposed markers, they shall be grouted to a depth of eighteen ( 18) inches into the rock. Right -of-way markers shall be installed at points designating the right - of-way boundaries and at each break in the right -of-way line as shown on the Plans or as directed by the Engineer.
638.3.2 -Installation: Markers shall be set plumb and to the depth shown on the Plans. The holes shall be backfilled with suitable material and thoroughly tamped. Right -of-way markers shall be set at points designating the right -of-way boundaries and at each break in the right -of-way line as shown on the Plans or as directe d by the Engineer. Right - of-way markers shall be accurately set to the mark given by means of intersecting strings. If approved by the Engineer, other equally accurate methods may be substituted.
638.4 -CONCRETE SURVEY MARKERS : Survey markers shall be installed where indicated on the Plans or as designated by the Engineer. When locations for survey markers conflict with other construction, the survey markers shall be offset as directed by the Engineer. Precast concrete markers shall be set plumb and to the depth shown on Plans. Installation shall be backfilled with suitable material and thoroughly tamped to obtain a very rigid installation. If a manufactured point on the bronze casting does not coincide with the survey point after installation, it shall be filed and the actual survey point shall be center punched and outlined by a cross.
