Rheological properties of dioctyl adipate-modified asphalt binder
The low temperature performance of DOA modified asphalt binder was improved by 30%. The residual creep rate ratio of the plasticizer-modified asphalt binder was more than 15% higher than base
Rheological properties of dioctyl adipate-modified asphalt binder
The rheological characteristics analysis shows that DOA could increase the viscous components in asphalt binder. However, with the increase of plasticizer content to 3.0%, the creep rate increased by 35% and the creep stiffness decreased by 39% at 24°C. The low temperature performance of DOA modified asphalt binder was improved by 30%.

- What is Dioctyl adipate (DOA)?
- Dioctyl adipate (DOA) serves as a crucial organic compound with significant roles across various industries. This article aims to provide a brief overview of DOA, including its chemical structure, properties, and applications in different sectors. As a type of diester compound, DOA possesses unique chemical properties and diverse uses.
- What is the structure of Dioctyl adipate?
- The structure of dioctyl adipate is as follows: This structure imparts several key properties to dioctyl adipate (DOA): ● (1) Low-temperature flexibility: DOA maintains flexibility even at low temperatures, ensuring optimal performance in cold environments.
- What is a good solvent for Dioctyl adipate?
- DOA is a non-polar molecule, meaning it tends to dissolve well in other non-polar solvents. Some examples of good solvents for DOA include aliphatic hydrocarbons such as hexane and heptane. The structure of dioctyl adipate is as follows: This structure imparts several key properties to dioctyl adipate (DOA):
- Is Dioctyl adipate toxic?
- Dioctyl Adipate has low toxicity, with an oral LD50 of 3000 to 6000 mg/kg in rats, and minimal irritation to skin and eyes. While DOA is considered to be non-toxic, it is important to handle it with care to avoid potential hazards.
- Is Dioctyl adipate polar or nonpolar?
- Dioctyl adipate (DOA) is an organic compound belonging to the ester class, with a chemical formula of (CH2CH2CO2C8H17)2. Its molecular structure consists of two octyl groups (C8H17) connected by a central adipate group (CH2CH2CO2). DOA is a non-polar molecule, meaning it tends to dissolve well in other non-polar solvents.
- What is DOA used for?
- DOA is often used in combination with primary plasticizers such as DOP for cold-resistant agricultural films, wires, thin sheets, synthetic leather, and packaging films for frozen foods. It can also serve as a low-temperature plasticizer for many synthetic rubbers and resins such as nitrocellulose.
