Section 611.3 - Construction Methods
A. Sub-Base
All underground sewer and water lines, utilities, laterals, service lines and related facilities shall be installed prior to any street construction.

B. Manholes and Catch Basins
If the surface course will not be applied within 90 days following the placement of the Binder Course, sanitary manholes and catch basins shall be installed so that their tops are at Binder Course grade level.
C. Base Course
After the sub-base has been properly prepared and the curbs or shoulders set, the Base Course of bank run gravel shall be spread for the full width and in such volume as to provide an eight (8) inch cross section after compaction with a ten (10) ton roller or equivalent.
D. Base Surface
Following thorough compaction of the Base Course, processed gravel shall be spread for the full width and in such volume as to provide a four (4) inch cross-section after compaction with a ten (10) ton roller or equivalent.
E. Binder Course
The Binder Course shall consist of an application of Bituminous Concrete Pavement (hot mix) Class I, Type I-1 applied as follows:
1. The Base Surface shall be clean of all debris, protrusions shall be removed from any holes, ripples or unevenness in the surface shall be brought back to true line and cross section, prior to Binder Course application.
2. The Binder Course shall be applied at a temperature of 250 - 350 degrees Fahrenheit by means of an approved paving spreader. Such material shall be placed in sufficient quantity to provide a minimum of compacted cross section of one-half (½) inch.
3. Compaction - The Binder Course shall be compacted as specified in section 401.03.11 of the R.I. Department of Transportation Standard Specifications.
F. Surface Course
The surface course shall consist of an application of Bituminous Concrete Pavement (hot mix) Class I, Type I-1, applied as follows:
1. The Binder Course shall be swept clean of all sand and debris. Ripples or unevenness in the surface shall be brought back to true line and cross section by the spot application and proper compaction of Class I mix.
2. The Surface Course shall be applied at a temperature of 250 - 350 degrees Fahrenheit by means of an approved paving spreader. Such material shall be placed in sufficient quantity to provide a minimum of compacted cross section of one and one-half (1 ½) inches.
3. Compaction - The surface course shall be compacted as specified in Section 401-03-11 of the R.I. Standard Specifications. Upon completion of the application and compaction of the Surface Course, the street shall be allowed to stand for a minimum of eight (8) hours without traffic.
Section 611.4 - Traffic Limitation
Traffic passing over constructed streets shall be limited to wheeled vehicles. No tracked equipment shall be permitted.
