Highway Construction Standards

All public roads/highways constructed or reconstructed subsequent to the date of this Ordinance in the Town of Grand Isle that are intended to qualify for maintenance by the Town, must meet the following standards. All public roads proposed, as part of a development plat, must have a Right-of-Way width of 60 feet.

Width of right-of-way: 60 feet. (Must be surveyed and recorded)

Width of public roadway: 20 feet traveled way with two foot shoulders either side,

centered in the Right-of-Way.

Location of traveled way: To be located where necessary to retain less than 9% grade.

Preparation of Subgrade and Sub-base conditions: Public roadway sub-base will be excavated to the extent required by the stone/fabric system. All boulders, organic material, soft clay, spongy material and any other objectionable and unsuitable material shall be removed and replaced with approved material according to the Engineering Plan. Approval of the Road Foreman is required prior to placing of stone course.

Base conditions: At least 15” of accepted and approved stone/fabric base will be placed the entire width of public roadway and shoulders. This item shall consist of a base course composed of fabric and stone as approved by the Road Foreman and constructed on a prepared subgrade in accordance with the sections as shown on the accepted drawings. All materials shall be secured from approved sources. Such material shall consist of hard, durable stones, which show uniform resistance to abrasion. The stone shall be 3” minus in size, a 4” inch layer of sand will be placed on top of the base coat. All bottom course material shall be deposited so as to distribute the material and compacted at optimum water content.

Public roads will be covered with 6” of approved surface material. This item shall consist of an upper course of crushed quarry material to be placed over the top of fabric and stone and sand then topped with finished stone, which will have been prepared in accordance with these specifications. This upper course shall be placed in accordance with the lines, grades, and typical cross sections as shown in the Engineering Plan. The upper course of crushed quarry material shall be deposited and spread in a uniform layer, and compacted at optimum water content.

Drainage – Drainage must be placed so that there will be no ponding of water within the highway right-of-way. Minimum culvert size will be 18” diameter. Larger may be required in some cases. Drainage ditches adjacent to public roads shall be provided where necessary and shall be a minimum of 18” below the finished grade.

Grades: All final grades must be approved. (It is suggested that the center line elevations be plotted and presented at the time of application for acceptance) Any public road, which the Town may accept into the Town Highway system, must meet the Selectboard’s approval for grade and design.

Approaches: All approaches to State Highways must be approved by the District Highway Engineer. Approaches to State Aid and Town Highways must be approved by the Selectmen or their agent.

Highways are to be paved prior to Town acceptance with hot bituminous concrete mix or a double tack coat with chipseal, meeting all of Vermont State Highway specifications.

1. Bituminous Concrete Pavement: This type of pavement shall be composed of mineral aggregate, mineral filler if required, and bituminous material, plant mixed and laid hot. This pavement shall be constructed in two (2) courses of the prepared or existing base in accordance with these specifications and in conformity with the lines, grades, thickness, and typical cross-sections shown on the accepted drawings. The course aggregate shall consist of clean, hard crushed rock or screened crushed gravel, free from dirt or foreign matter. It shall be reasonably free from soft and elongated pieces. The fine mineral aggregate shall consist of sand or a mixture of sand and stone screenings of which at least fifty percent (50%) by weight shall be sand. The sand shall consist of clean, hard, durable grains, free from injurious amounts of vegetable matter or other harmful substances. The asphalt cement shall conform to all the requirements as set forth by the State of Vermont Department of Highways Specifications for Highway construction. The bituminous concrete is to be laid and rolled by experienced crews, in two layers. The first, the binder course to a depth compacted to 1 ½”. The second application compacted to a depth of 1” of hot bituminous concrete, surface mix. All work to be done in a professional manner and must be approved by the Road Foreman. Equipment for spreading and finishing the mixture shall be a mechanical spreading and finishing machine provided with an activated screen and heated as required. The machine shall be capable of spreading the mixture without segregation and shall be approved by the Road Foreman before being used. The base coat will stand a minimum of twelve months before application of the finish coat of pavement.

2. An alternative to bituminous concrete pavement is the use of a double tack coat with Chipseal composed of ¾ and ½ inch stone base with a 3/8 inch stone surface layer combined with a water based emulsion binder meeting all of Vermont State Highway specifications. This material must be applied by experienced Construction crews using equipment, which has been approved by the Road Foreman before use.

Trees and Foliage: All trees and shrubs will be removed for a distance of 20 feet from the center line of the public roadway. (In some circumstances, these requirements may be waived.)
