The aggregate to be used for asphalt concrete shall consist of very hard crushed rock, shall have a minimum compressive strength of 1250 kg/sq.cm., shall be of the gradation indicated below, and shall not be readily wet by water. Fine aggregate shall consist of natural sand or sand obtained from siliceous crushed stone. The admixture shall meet the requirements of CNR. Solid or liquid bitumen shall be as specified by the "Norme per l'accettazione dei bitumi per usi stradali" (standard for acceptance of bitumens for road work), Pamphlet 2 of CNR (1951).

MIX PERCENTAGE BY WEIGHT

Siliceous sand 25%

Aggregate - size 2-7 mm. 15%

5-10 mm. 20%

10-15 mm. 16%

15-18 mm. 20%

Bitumen 4-5%

When viscosity type cut-back asphalt is used, the admixture shall be added to a percentage ranging between 2% and 3% of the total weight. When solid high penetration asphalt is used, the aggregate material shall be dried and heated beforehand at a temperature of 120-160 degrees C and the dust removed. The material shall be hauled and spread in such a manner as to avoid excessive heat loss and to prevent the mix from being altered or soiled. Variations in the mixture shall not exceed 1% for asphalt and 10% for each aggregate grading. When concrete is spread manually, the ordinary methods shall be followed using steel rakes. Concrete shall be rolled by quick reverse type rollers weighing no less than 5 tons. Roller wheels shall be sprinkled with water to prevent pick up of the bituminous material. Rolling shall progress gradually from the edges of the hardstand to the center. The first trips shall be run with particular care to avoid the danger of waves or cracks in the course. When the course has settled, the roller shall be run transversely over the surface. Rolling shall stop upon compaction. All edges and borders around the paved surface and its single sections, such as joints where work is resumed, lateral curbs, underground utility outlets, etc., prior to receiving the asphalt concrete course, shall be coated with one layer of asphalt to insure full waterproofing and adhesion of the parts. All joints and borders shall be tamped and hand finished by special rectangular base type tampers.

Irregularities or waves on any point of the finished surface shall not exceed 5 mm.

11a-08 WEARING COURSE. The pavement shall be completed by application of a hot-laid close type asphalt concrete course. The size and quality of coarse and fine aggregate, sand, and admixture shall be as described in paragraph 11a-09. After adding the admixture, the voids in the total mix aggregate material shall not exceed 20-22% of the total volume. When mixed, the bitumen shall have a penetration value of 80-100 (or even up to 120), and its contents in the mixture shall be 6-7.5% of the dry aggregate weight. The maximum allowed percentage of voids shall be 5%. Aggregate shall be preheated at a temperature not to exceed 120 degrees C, and the binder 130 degrees C. The mix proportions shall be as follows:

a. Coarse aggregate From 40% to 60% (3-15 mm.)

b. Fine aggregate From 25% to 40% (sand grain spassing 2 mm. sieve)

c. Admixture From 4% to 10% (asphalt powder passing 0.297 sieve)

d. Bitumen From 5% to 8%.

When the base surface has received an emulsified asphalt layer at the rate of 1 kg/square meter, the mix shall be hot-laid in the quantity necessary to attain the final required thickness. The course shall then be rolled as specified in paragraph 11a-07. The finished surface shall be coated with hot-laid asphalt applied at the rate of 0.700 kg/square meter, and the remaining voids filled with asphalt powder and by rolling.

The rolling will be executed with the number of times (in any case not fewer than 20) deemed necessary to obtain perfect compaction according to the quality and hardness of the material used.
