SAES-Q-006

Asphalt and Sulfur Extended Asphalt Concrete Paving

The SAES-Q-006 Standard provides the following information regarding the design and construction of asphalt concrete paving:

• The standard covers the minimum mandatory requirements for the design and construction of asphalt concrete paving, including the use of Sulfur Extended Asphalt.
• It does not apply to airfield pavement. Design and construction details for permanent airstrips are covered in Standard Drawing AA-036257 and appropriate FAA specifications.
• Helipad design and construction details are covered in Standard Drawing AA-036246.
• The standard does not apply to asphalt concrete paving for non-traffic areas such as secondary containment dikes or erosion control for slopes.

The standard specifies the mandatory requirements for asphalt concrete paving, ensuring that the design and construction meet the necessary standards and quality. However, specific details regarding the design and construction process are not provided in the excerpt.

Specification for Asphalt and Sulfur Extended Asphalt Pavement

The specification for preparation of subgrade materials in the construction of asphalt and sulfur extended asphalt pavement includes the following requirements:

1. Vegetation Removal and Surface Leveling:

• All vegetation on the subgrade should be removed.
• Depressions should be filled, and the surface should be leveled.

1. Rough Grading and Surfacing:

• If rough grading is part of the contract, it should be completed before the surfacing construction begins.
• Soft and unstable material that cannot be compacted should be removed and replaced with approved material.

1. Compaction and Moisture Content:

• The entire subgrade should be compacted to a minimum of 95% of the maximum dry density determined by ASTM D1557 or AASHTO T180.
• The moisture content should be within 1.5% of the optimum moisture content or to 85% of relative density determined by ASTM D4253 and ASTM D4254.
• Corrections should be made for any holes, ruts, soft places, or defects in the subgrade.
• The subbase or base course should not be placed on soft or unstable material or areas that are not drained.
• Construction operations should be delayed if the subgrade is dusty or muddy until it meets the approval of the Saudi Aramco representative.

1. Alignment, Grade, and Cross-Section:

• The subgrade should conform to the alignment, grade, and cross-section shown on the plans.
• Variations should not exceed +6 mm as measured with a 3 m straight edge.

1. Compaction Methods:

• In areas inaccessible to a roller, compaction can be achieved using a mechanical or hand tamper approved by the Saudi Aramco representative.

1. Approval and Drainage:

• The Saudi Aramco representative should approve the constructed subgrade before starting the construction of the subbase or base course.
• Proper drainage should be maintained during the placement and compaction of the base course or subbase surface.
• If berms of earth are deposited, lateral ditches should be cut through them to ensure surface drainage.

1. Maintenance:

• The finished subgrade should be kept smooth and compacted until the subbase, base course, and surface course are placed.

These specifications ensure that the subgrade is properly prepared to meet the requirements for the subsequent layers of the pavement construction.
