About this file
This document is a Louisiana Department of Transportation and Development (DOTD) Material Specification (MS Spec. 164-004) for Polymer Modified Asphaltic Materials, revised on 12-20-2017. The specification provides detailed technical requirements for polymer modified asphaltic materials used in road maintenance, including two primary performance grades: PG76-22m and PG70-22m. The document outlines comprehensive testing methodologies, specification parameters, and acceptance criteria for these materials, covering tests on original binder, rolling thin film oven residue, and pressure aging vessel residue.
The specification includes two detailed tables: Table 1 covers Polymer Modified Asphalt Cements with extensive testing requirements across multiple properties such as rotational viscosity, dynamic shear, flash point, solubility, and creep recovery, while Table 2 addresses Anionic Emulsified Asphalt (SS-1h) with specifications for viscosity, distillation residue, sieve test, settlement, and penetration. The document emphasizes quality control, requiring materials to be uniform, free from water, and sourced from the Approved Materials List. Payment adjustments are specified for deviations from the established specifications, and samples taken at the point of delivery will be used to determine conformance, with refinery samples required to meet specification requirements or risk rejection.

SPECIFICATIONS
POLYMER MODIFIED ASPHALTIC MATERIALS
DESCRIPTION:
These specifications cover polymer modified asphaltic materials for road maintenance.
GENERAL REQUIREMENTS:
Polymer modified asphalt shall be prepared by the refining of petroleum. It shall be uniform in character, free from water, and shall not foam when heated to 350º. Asphalt shall be from the Approved Materials List.
Storage tanks, piping, retorts, booster tanks, distributors and other equipment used in delivering, storing or handling asphaltic materials shall be kept clean and in good operating condition and shall be operated in such manner as to avoid contamination of the contents with foreign materials.
Test methods shall be the latest in effect in addition to the ones included in this specification.
Final test results for polymer modified asphaltic materials will be applied to the proper table herein for conformance to specifications. Any deviation from the specifications will result in a payment adjustment as specified. If test results are such that a price adjustment would result from more than 1 test value, the payment adjustment for the greatest reduction shall apply.
The adjustment in pay for polymer modified asphaltic materials shall be applied only to samples taken at the point of delivery. Samples taken at the refinery shall conform to specification requirements; if the refinery sample fails to meet these requirements, the material will be rejected and shall not be shipped.
SAMPLING:
Sampling will be in accordance with the Materials Sampling Manual.

1Tank mixers are required. Submit written documentation of tank cleaning annually.
2The rotational viscosity will be measured to determine product uniformity. The rotational viscosity measured by the supplier shall be noted on the Certificate of Delivery. A binder having a rotational viscosity of 3.0 Pa·s or less will typically have adequate mixing and pumping capabilities. Binders with rotational viscosity values higher than 3.0 Pa·s should be used with caution and only after consulting with the supplier as to any special handling procedures and guarantees of mixing and pumping capabilities.
3Not all polymers are soluble in the specified solvents. If the polymer modified asphalt digested in the solvent will not pass the filter media, a sample of the base asphalt used in making the polymer modified asphalt should be tested for solubility.
If the solubility of the base asphalt is at least 99.0%, the material will be considered as passing.
4Prepare samples per ASTM D7173. Determine softening point of top and bottom per AASHTO T 53.
