§ A201-1 Preparation of subgrade.

A. 
The subgrade area shall be cleared of fences, trees, logs, stumps, brush, vegetation, rubbish and any other perishable or objectional matter. The area shall be stripped of all topsoil, and any other unsuitable material encountered shall be removed and replaced with material suitable for fill under pavements.
B. 
The subgrade shall be properly prepared by bringing to the designed line and grade the suitable materials available at hand, if any, or such other suitable materials as loam, course sand, gravel, stone dust or cinders. These subgrade materials shall be mixed, stabilized, compacted and rolled with a ten-ton roller, in such a manner as to produce a stable surface upon which the stone base will be placed. If materials are sandy or of such consistency that they will not produce a hard surface, additional loam of approved quality free from all vegetable or other foreign matter shall be added. The subgrade shall be rolled thoroughly with a roller weighing not less than 10 tons until the entire surface is firm and will not heave or be otherwise distorted by the rolling operation. If any soft or other unstable areas develop within the surface limits of the pavement, the deleterious material shall be removed and suitable material replaced and rolled so that a proper subgrade true to line and grade is produced. Before the stone base is placed, this subgrade must be approved and accepted by the Engineer or Superintendent of Public Works.

§ A201-2 Stone base.

A. 
Upon the subgrade, a base course of broken stone shall be uniformly placed so that after rolling and compacting a minimum depth of four and one-half (4 1/2) inches is obtained. The broken stone shall consist of clean hard, tough durable traprock resistant to wear and frost and free from an injurious amount of deleterious substances. An excess of flat or elongated fragments will be cause for rejection.
B. 
Broken stone shall be free from dust or dust coating and shall conform to the following sizes:
Passing Square Opening
Retained Square Opening
Percent by Weight
2-inch
1 1/2-inch
45 to 65
1 1/2-inch
1-inch
35 to 55
1-inch
0 to 10
C. 
The stone shall be evenly spread to a thickness that will produce the required thickness of the course after compaction.
D. 
After the foundation course has been laid loose, it shall be shaped and rolled with a self-power roller weighing at least 10 tons. Rolling shall be continued until a firm, even surface of the required cross section is obtained. Any defects in the grade of the surface shall be corrected while rolling. Should the subgrade material be churned up and mixed with the foundation course through any reason whatsoever or the surface of the foundation course become filled with mud or dirt before the course has been filled, rolled and completed, the affected areas shall be removed and replaced with clean stone. In confined areas not accessible to rollers, pneumatic tampers shall be used.
E. 
Upon the compacted stone base, hot asphalt, of Penetration Grade 85-100, shall be applied uniformly over the entire surface at the rate of two gallons per square yard. The asphalt shall be heated to a temperature of between two hundred seventy-five degrees and three hundred degrees Fahrenheit (250° and 300° F.) and distributed evenly over the entire surface by the use of an approved pressure distributor operating under a pressure of 50 pounds per square inch.
F. 
In small areas or adjacent to structures, application may be made with hand pots. In spreading adjacent strips, the material shall not lap over the previous application. Adjacent concrete pavement, curbs and structures shall be protected from asphalt by paper or sand covering.
G. 
Asphalt Cement Grade 100-120 will be required in cool weather, that is below 50° F.; application shall not be made when in temperature below 35° F.
H. 
Immediately after penetrating the stone base, there shall be evenly distributed broken stone filler at the rate of 40 pounds per square yard, or more, to the entire surface.
I. 
Broken stone filler shall be free from dust or dust coating graded as follows:
Passing Square
Retained Square
Percentage by Weight
1-inch
5/8-inch
0 to 10
5/8-inch
3/8-inch
50 to 70
3/8-inch
1/4-inch
20 to 40
1/4-inch
0 to 10
J. 
The stone shall be broomed to fill all surface voids without forming a distinct layer. While the asphalt is still warm, the surface shall be rolled with a ten-ton roller. After the first rolling, the surface shall be broomed and additional filler added where necessary. Rolling and brooming shall be continued until voids are filled and the foundation is compacted to true and even surface at the established grade. All loose stone shall be removed before the next course is placed.

§ A201-3 Asphaltic concrete surface.

A. 
Materials.
(1) 
Asphalt cement. The asphalt cement shall meet the following requirements:
(a) 
It shall be homogeneous and free from water.
(b) 
The specific gravity at 77° F. shall be between 1.00 and 1.04 for petroleum asphalts.
(c) 
The penetration at 77° F., 100 grams, five seconds shall be not less than 85 nor more than 100.
(d) 
The percent penetration at 77° F., 100 grams, five seconds shall be not less than 30.
(e) 
The percent penetration at 39.2° F., 200 grams, one minute to the penetration at 77° F., 100 grams, five seconds shall be not less than 30.
(f) 
The loss on heating at 325° F. shall be not more than a percent, and the penetration of the residue shall be not less than 60.
(g) 
It shall have a solubility in carbon tetrachloride of not less than 99.5% for petroleum asphalts.
(h) 
It shall not flash below 34.7° F. when tested by the Cleveland Open Cup Method.
(i) 
The ductility at 77° F. shall not be less than 60.
(2) 
Asphaltic concrete.
(a) 
After the base course has been completed, a one-course surfacing of one-and-one-half-inch asphaltic concrete shall be placed. The asphaltic concrete shall consist of a uniform mixture of broken stone, sand, mineral filler and hot asphalt cement which, when tested by means of laboratory sieves and screens, shall meet the following weight requirements:

(c) 
Material shall not be placed on wet base or placed while rain or snow is falling. No material shall be placed when the temperature is below 32° F.

§ A201-4 Preparation of subbase.

A. 
The subbase area shall be cleared of fences, trees, logs, stumps, brush, vegetation, rubbish and any other perishable or objectionable matter. The area shall be stripped of all topsoil, and any other unsuitable material encountered shall be removed and replaced with material suitable for fill under pavements.
B. 
The subbase shall be properly prepared by bringing to the designed line and grade the suitable materials available at hand, if any, or such other suitable materials as loam, course sand, gravel, stone dust or cinders. These subbase materials shall be mixed, stabilized, compacted and rolled with a ten-ton roller, in such a manner as to produce a stable surface upon which three coats of oil will be placed. If materials are sandy or of such consistency that they will not produce a hard surface, additional loam of approved quality free from all vegetable or other foreign matter shall be added. The subbase shall be rolled thoroughly with a roller weighing not less than 10 tons until the entire surface is firm and will not heave or be otherwise distorted by the rolling operation. If any soft or other unstable areas develop within the surface limits of the pavement, the deleterious material shall be removed and suitable material replaced and rolled so that a proper subbase true to line and grade is produced. Before commencing to oil, this subbase must be approved and accepted by the Engineer or Superintendent of Public Works.

§ A201-5 Finished surface.

A. 
After the subbase has been approved, one-half (1/2) gallon of MC-2 per square yard shall be applied with a blotter coat of sand sufficient to absorb any excess oil and rolled with a ten-ton roller.
B. 
Within 60 days, but not less than 15 days after applying the first coat of oil, 1/2 gallon of RC-2 per square yard shall be applied and covered with 3/8-inch crushed stone at 25 pounds per square yard, broomed, rolled with a ten-ton roller and all excess stone removed.
C. 
Within one year, but not less than 90 days after applying the second coat of oil, 1/2 gallon of RC-2 per square yard shall be applied and covered with 3/8-inch crushed stone at 25 pounds per square yard, broomed, rolled with a ten-ton roller and all excess stone removed.
