About this file
This is a specifications document issued by the Louisiana Department of Transportation and Development (DOTD) that establishes standards for aggregate materials used in asphalt surface treatment applications, commonly known as chip seals. The document defines requirements for three aggregate sizes (Size 1, Size 2, and Size 3) and specifies that materials must be sourced from the Approved Materials List and comply with Subsection 1003.01 of the 2016 Louisiana Standard Specifications for Roads and Bridges. The aggregate may consist of crushed gravel, crushed stone, or lightweight aggregate. Crushed gravel Size 1 and Size 2 must have a minimum of 60 percent crushed material retained on the No. 4 sieve, while Size 3 requires 75 percent crushed retention on the same sieve. The specifications include detailed gradation requirements presented in tabular format, specifying the percentage of material passing various sieve sizes for each aggregate classification.
The document establishes specific performance standards for particle size distribution and material composition but does not include pricing information, contract terms, award dates, or funding details. Sampling procedures are to be conducted in accordance with the Materials Sampling Manual. The specifications were approved for the Maintenance Division and are effective as of the revision date of July 13, 2023. The document applies to Product IDs MS 274-006, 11478, 11479, 11480, 11481, 11482, and 54750.

SPECIFICATIONS
AGGREGATE FOR ASPHALT SURFACE TREATMENT
DESCRIPTION: This aggregate is for use in asphalt surface treatment applications, sometimes referred to as chip seals.
GENERAL REQUIREMENTS: Aggregate shall be crushed gravel, crushed stone, or lightweight aggregate from the Approved Materials List and comply with Subsection 1003.01 of the 2016 Louisiana Standard Specifications for Roads and Bridges.
SPECIFIC REQUIREMENTS: Crushed gravel Size 1 and Size 2 shall have 60 percent minimum crushed retained on the No. 4 (4.75 mm) sieve. Crushed gravel Size 3 shall have 75 percent crushed retained on the No. 4 (4.75 mm) sieve. Determine the percent crushed in accordance with DOTD
TR 306.
Comply with the following gradation:

1 The percentage passing the No. 200 (75 μm) sieve shall be 0 - 2 percent for crushed aggregates when the materials finer than the No. 200 (75 μm) sieve consist of dust fraction from crushing and handling, essentially free of clay.
2 Uncrushed gravel may be used for Size 1 aggregate if more than one application of Asphaltic Surface Treatment is required.
SAMPLING: Sampling will be in accordance with the Materials Sampling Manual.
