§ A206-40. Surface treatment of shoulders.

A. 

On rural-type roads where a five-foot-wide paved shoulder is required as shown on , the shoulder shall be constructed and shaped immediately following the construction of the base course pavement. Shoulders shall be constructed of select gravel, approved by the Town Superintendent of Highways and/or the Town Engineer, and shaped and rolled with a ten-ton steel-tired roller to grade as shown on .

B. 

A double surface treatment shall be applied to shoulders as follows:

(1) 

Apply a uniform application of RT-4 to the shaped and rolled gravel shoulders at the rate of 0.50 gallon per square yard.

(2) 

Uniformly spread with a gravity-type mechanical spreader about 25 pounds of clean 1/2-inch crushed stone or crushed gravel per square yard.

(3) 

Broom to distribute stone evenly and roll with a ten-ton steel-tired roller.

(4) 

Apply a uniform application of 64-P or MC-5 at the rate of 0.50 gallon per square yard.

(5) 

Uniformly spread with a gravity-type mechanical spreader about 25 pounds of clean 1/2-inch crushed stone or crushed gravel per square yard and roll with a ten-ton effective weight steel-tired roller.

C. 

It will be noted that the second surface treatment of pavement shall be simultaneous with the second surface treatment of shoulders so that the pavement and shoulders present a uniform appearance on completion.
