Alterations or modifications to specifications. A. Whenever, in the opinion of the Superintendent of Highways, he finds that, for the best interest of the town, alterations or modifications should be made to specifications, rules and regulations, such alterations or modifications may be made on the recommendation of the Superintendent of Highways to and with the approval of the Town Board. B. [Added 9-20-88) In a major subdivision when the number of lots to be served by a proposed street is four (4) or fewer and, further, there is no likelihood of the street servicing more than four (4) lots, the Planning Board, at its discretion, may waive the major road specifications as set forth herein and, in their place, substitute the following alternative road specifications: (1) Base course for asphalt pavement (a) The base course shall consist of three-fourths-inch stone blend or crushed concrete compacted to a four- inch depth. If clay or other unsuitable material is found below the base course, it shall be removed and replaced with twelve (12) inches of compacted bank- run containing ten percent (10%) or more of gravel. The twelve•inch replacement depth may be modified according to existing conditions as approved by the Engineer. (b) The soil base shall be compacted to the satisfaction of the Engineer and shall be smooth, parallel to and at the required depth below the base course. The soil base shall not be in a muddy or frozen condition before placing base course material.

(b) The binder course shall be placed on the stabilized base course when it has been satisfactorily complet- ed and approved by the Engineer or Inspector. The material shall be placed only when the surface to be covered is dry and clean and weather conditions, in the opinion of the Engineer, are suitable. All defective areas in the base course shall be repaired as directed. The bituminous courses shall be placed with an approved finishing paver with screed heating equipment, capable of placing afourteen- foot width and to such appropriate loose depth that, when the work is completed, the required compacted thickness will have been meth The courses shall be compacted with ten-ton tandem steel wheel rollers or vibratory rollers of a type as approved by the Engineer. During the initial rolling, rollers shall travel parallel to the center line, beginning at an • edge and working toward the center, overlapping on successive passes by one-half (~) of the roller wheels. A minimum of four (4) passes of rollers will be required. A10828 u - zs - as § A108-42 HIGHWAY SPECIFICATIONS § A108-42 (c) The wearing course shall consist of one (1) of the following materials: [1] Asphalt concrete one an one-half (1F) inches in compacted depth.

The aggregate shall have the following composition: General Limits (Percent passage Screen size by weight) -inch 100 '/a-inch 90 to 100 l~-inch 0 to 15 (d) The double-application bituminous surface treat- • ment, when required, shall not be placed until the binder course has been satisfactorily completed, cured and approved by the Engineer. The liquid asphalt shall be evenly applied to the road surface by means of a pressure distributor, at one hundred twenty-five degrees to one hundred eighty-five A10830 11 -'LG - NR § A108-42 HIGHWAY SPECIFICATIONS § A108-42 degrees Fahrenheit (125° to 185° F.) and at the rate specified. The distributor shall be equipped with an accurate measuring device which indicates the exact number of gallons remaining within the distributor tank. Note that the rate of application may be adjusted depending on the specific gradation of the crushed blue stone to be used. No asphalt shall be • applied unless sufficient truckloads of aggregate are standing by at the paving site and, in the opinion of the Engineer, all asphalt distributed will be immediately covered with aggregate. Sufficient time shall elapse between the completion of the first course and the placing of the second course so that the bituminous material in the first course has time to set or cure. Prior to the placement of the second course, the surface to be paved shall bedrag- broomed, and the excess on the sides of the roads shall be evenly distributed across the entire width of the pavement. Any damage to the pavement shall be repaired with asphalt and stone applications prior to the placement of the second course. Additional stone shall be applied to take up any bleeding that occurs. All rolling shall be done by pneumatic-tired rollers or steel-wheeled rollers no heavier than eight (8) tons.
